How to Make Marshmallow Fondant

Save Recipe

Marshmallow Fondant is easy to make, beautiful to decorate with, and uses just THREE ingredients!

Hi Bold Bakers!

Have you ever heard me say I’m not a cake decorator? I mean at all! Over 15-plus-years as a professional pastry chef, I was rarely in the position where I had to decorate a cake — never mind covering the thing in fondant.

So, why make marshmallow fondant? More traditional rolled fondant recipes require a few more ingredients and you more than likely won’t have them on hand. Marshmallow Fondant is a bag of marshmallows and icing sugar, That’s all you need.



Making your own fondant is inexpensive and fast. I have a great tip on fondant making and coloring on this post for my traditional Fondant recipe.

What’s the difference between Marshmallow Fondant and regular Fondant?

Actually there is really very little difference between marshmallow fondant and traditional fondant when it comes to the ingredients in them. Although marshmallow fondant is just 3 ingredients, and traditional fondant is many more, they are basically made up of the same things.

Marshmallows fondant is quicker and easier to make because the first step is already done for you when you use marshmallows that are already made. Basically all you need to do is melt down the marshmallows, then add a little water and powdered sugar to get it to the right consistency. If you are new to cake decorating, and are starting out, I strongly recommend marshmallow fondant over traditional fondant.

Start to finish I just find it so much easier to work with!

How To Make Your Own Marshmallow Fondant

Quick and easy, with very few ingredients — that’s how!

First, you need to melt your marshmallows. Pour your big bag of marshmallows into a microwave-safe bowl, add a little bit of water, and put it in the microwave until melted. Once melted, you add in your icing sugar (recipe measurement below!) and you mix — you can do this by hand, but it will take some elbow grease for sure.

After the fondant begins to come together, you drop it onto a well-oiled surface and you knead (and add some more icing sugar) until it’s nice and smooth! Once it’s kneaded, you can then add any color you’d like to it.

How To Store Marshmallow Fondant

To store Fondant and use at a later date, cover it in a little vegetable oil (like below) and store it in an airtight bag. The less air the better so your fondant doesn’t dry out.

How to Make Marshmallow Fondant

Marshmallow Fondant is easy to make, is beautiful, and uses just THREE ingredients!

Course: Dessert
Cuisine: American
Author: Gemma Stafford
  • 1 Bag (10oz /280g) mini marshmallows (good brand)
  • 2-3 tablespoons water
  • 4 cups (453g/1lb) powdered sugar
  • Flavorless oil (little for hands while kneading)
  1. First melt marshmallows and water in a double boiler or in a microwave for 30 seconds at a time. Set aside once melted.

  2. *To make it in a kitchen mixer*, add in 3/4 of the powdered into the mixing bowl, followed by the marshmallow mixture, then mix together on low speed until you have incorporated a lot of the sugar and your fondant is coming together to form a ball. (NOTE: If your dough is still sticky at this point, add more powdered sugar until it forms a ball.)

    Then turn out on the counter add the rest of the reserved sugar bit by bit. Then knead — Knead Knead! — for about 7 minutes until it is soft and shiny. If it starts to feel a bit dry, add 1/2 Tbsp. water at a time until it feels soft and pliable – then keep kneading.

  3. *By hand*, stir 3/4 of the powdered sugar into the marshmallow mixture, then knead in the remaining 1/4 until it is all incorporated into the mixture. Then turn out on the counter and Knead Knead Knead! for about 7 minutes until it is soft and shiny. Incorporate the reserved sugar as you knead. If it starts to feel a bit dry, add 1/2 Tbsp. water at a time until it feels soft and pliable – then keep kneading.

  4. Note: be sure to grease your hands and counter before dumping mixture from bowl
  5. To add color to your fondant. Add a small amount of food coloring with a toothpick, then Knead Knead Knead! for about 7 minutes until it is soft and shiny. If it starts to feel a bit dry, add 1/2 Tbsp. water at a time until it feels soft and pliable – then keep kneading.

  6. To store your fondant to be used later, grease the outside of the ball and double wrap in saran wrap, then put in a ziplock bag to keep it moist.
  7. Roll your fondant on on your surface well dusted with icing sugar. Move it around so it is not sticking in one spot. Roll it to the desired size of your cake.
  8. For the hearts cut them out with a cutter. You can actually cut these out in advance and let them dry out. I let my hearts dry out in the open air to firm them up. They are easier to apply when they are firm.
  9. Your Fondant will last for weeks when stored airtight. Even your cut out hearts will stay perfect until you need them.

Recipe Notes

I do my best to give very precise recipes but with a global audience and different brands of marshmallows and sugar sometimes there is a difference and yields different results. 

If you find your fondant is sticky after you have added the powdered sugar then add more until it firms up into a ball.

    Hi Gemma do you need to sift powdered sugar first i have made a marshmallow fondant before that you needed to sift it and it was such a chore trying to do that.

    • Gemma Stafford on March 1, 2019 at 1:29 pm

      Hi, yes this will make it nice and smooth 😀

    • Nick on March 26, 2019 at 2:42 pm

      Love the recipe; going to try it out tonight for my son’s bday party coming up this weekend. I’m making an ice cream cake; can this be frozen? If so what happens; does it become hard and crack or brittle?

      Thank you for your help

      • Gemma Stafford on March 27, 2019 at 4:05 pm

        Hi, they will become hard, but after defrosted they will return to the correct texture.

  2. gina081369 on February 22, 2019 at 7:04 pm

    Hi, can I use powdered milk instead of powdered sugar to mix with the marshmallow in making fondant?

    • Gemma Stafford on February 22, 2019 at 11:04 pm

      I would not suggest that.

  3. Tina on February 22, 2019 at 6:25 pm

    Hi Gemma,I really like your recipes.Thank you for sharing it.What type of marshmallow that you use?I have tried mine but it is still sticky.How long do i have to leave it aside after melting, before kneading with sugar icing?

    • Gemma Stafford on February 22, 2019 at 11:08 pm

      Hi, you can use generic marshmallows here and no need to wait after they are melted.

  4. Jessica on February 21, 2019 at 5:05 pm

    I am making a wolf themed cake. I saw a cute picture where the wolf was made of fondant but was it looked like a flat cut out of the wolf, but it was standing up on the top of the cake. If I roll the fondant out, cut out the outline and let it air dry, will it harden enough that it won’t just flop over? If so, how long do I need to let it dry before it hardens enough that it won’t flop or fold down?

    • Gemma Stafford on February 21, 2019 at 9:10 pm

      Hi, yes that will work and sounds adorable. I suggest 24 hours to dry.

  5. Christina on February 18, 2019 at 9:21 pm

    Hi! What do you consider a good brand for marshmallow? Jet-Puffed?
    Thanks! 🙂

    • Gemma Stafford on February 19, 2019 at 3:22 pm

      Yes, any generic bran will do here. Enjoy!

  6. Christina on February 18, 2019 at 9:16 pm

    I wanted to make this for this weekend and I was wondering, is vegetable oil considered flavorless oil? Thank you! 🙂

    • Gemma Stafford on February 19, 2019 at 3:23 pm

      Yes, that’s perfect.

  7. Rea on February 11, 2019 at 4:07 pm

    Hi Gemma,
    Attempting to make my first fondant covered cake for my son’s birthday in a few days. I made a batch of a fondant following your instructions. It turned out great. Thanks to you. I have a question whether this fondant can be used to make figures. I plan on making an airplane topper. Will it work or do I need to buy tylose powder? TIA

    • Gemma Stafford on February 12, 2019 at 10:05 am

      Hi,great job! Yes you can use it to make all kinds of shapes. Enjoy!

  8. Helen Darby on February 11, 2019 at 1:03 pm

    Can I make moulding icing from this recipe

    • Gemma Stafford on February 12, 2019 at 9:59 am

      Hi, yes you can 😀

  9. Jessikah on February 11, 2019 at 8:29 am


    I made this last night and it was really hard to work with and roll out Andy by hard I mean it was super firm. Reading the reviews I’m thinking I did something wrong! Any thoughts?

    • Gemma Stafford on February 12, 2019 at 10:29 am

      Hi there, if that’s the case you might have added too much powdered sugar which can make it on the dry side. To avoid this you sift the powdered sugar.

  10. Marline on January 30, 2019 at 5:10 am

    Hi Gemma, i am new to your group… My name is Marline….i would like to know when we make fondant can we use it the same time or do we have to keep it in the fridge and use it the next day? And how do we need to store the fondant? Please help me thanks Marline

    • Gemma Stafford on January 30, 2019 at 4:50 pm

      For this you can use it right away. To store it i suggest putting it in a plastic bag some flavorless oil to make sure it does not stick! Enjoy!

  11. Gugu on January 29, 2019 at 7:54 am

    Hi Gemma, I’m not sure if you received my question earlier.
    I’m about to try making the marshmallow rolled fondant for the very first time, what type of marshmallow should I use? Here we have Manhattan fluffy and puffy And Beacon mallows, and they cum in 2 colors in a bag

    • Gemma Stafford on January 29, 2019 at 4:11 pm

      For this you can use kind of generic marshmallows 😀 Enjoy!

  12. Alicia Mitic on January 28, 2019 at 2:35 pm

    One more question (sorry!). Is it okay to use normal size marshmallows rather than mini ones if they are better quality?


    • Gemma Stafford on January 29, 2019 at 1:02 am

      Hi Alicia,
      You can use larger marshmallows, but they are formulated differently. You may need more powdered sugar to bring it together. I suggest you make a sample recipe, see how it works for you,
      Gemma 🙂

  13. Alicia Mitic on January 28, 2019 at 2:29 pm

    Hi Gemma,

    Approx how big a cake would this fondant recipe cover? I’m wondering how much to make to cover a dolly varden shape.


    • Gemma Stafford on January 29, 2019 at 1:01 am

      Hi Alicia,
      This is a difficult question for me to answer! The recipe here will cover a 7 inch cake or so. After that it depends on the complexity of the shape and the size of your cake. To attach a fondant to any cake it is best to use a buttercream crumb coat. Set this up in the fridge. It will make your cake easier to manage.
      Thank you for being in touch, I wish you well with your cake,
      Gemma 🙂

  14. Chantal Batchilder on January 27, 2019 at 10:14 am

    Can you freeze the finished product? ( cake covered in fondant) also how thin do you roll the fondant?

    • Gemma Stafford on January 28, 2019 at 2:11 am

      Hi Chantal,
      You will see in this recipe how I use it ( There is a lot of information here for you. You can freeze this once it is finished. Defrost slowly in the fridge to prevent the frosting sweating.
      I hope this is of help,
      Gemma 🙂

  15. Aggie on January 20, 2019 at 4:03 pm

    I have a question
    Can you make it ahead of time and store somewhere?

    • Gemma Stafford on January 21, 2019 at 2:04 am

      Hi Aggie,
      You can, and you will need to wrap it really tightly in cling wrap to exclude all the air. Best not to store it too long, it would be as quick to make it as to get it ready for rolling if you store it in the fridge. A cool room temperature for a day or so, fridge for a few days.
      I hope you enjoy this recipe,
      Gemma 🙂

  16. MK on January 16, 2019 at 2:15 pm

    Hello Gemma,
    I’m a newbie with anything related to baking. I can count with one hand of how many times I have baked in my whole life and I don’t own a mixer. What other ways can I mix the marshmallows and powdered sugar? Will a spatula in bowl work? Perhaps I should just buy the ready made Fondant. Will have to go shop to make two special cakes for my dad, and my soon to be 3 years old son!

    Look forward to your help.
    Thank you dearly!

    • Gemma Stafford on January 19, 2019 at 1:39 am

      Hi there,
      Really you cannot make powdered sugar without something to help, a pestle and mortar would do it for you, but it will be a challenge.
      I think if you do not have some equipment, and no experience, you may need to either use marshmallow fondant, or buy it ready made, though I am reluctant to say that.
      Fondant is a tricky thing to make, experienced bakers often avoid it. Marshmallow fondant is easy, and effective, provided the ingredients are right, you will not need equipment for this one, just use what you have and a bit of elbow grease.
      I hope this all goes well for you, it is so nice to have a special cake, made especially for you,
      Gemma 🙂

  17. Patricia C Orourke on January 13, 2019 at 9:23 pm

    Hi Gemma,

    I want to try your marshmallow fondant. I would like to put it on your Best chocolate cake, which I love. I have seen other recipes that add butter to it. Would it be easier with the butter, although probably not as white in color? Why do they add the butter.

    Thanks for your help.


    • Gemma Stafford on January 14, 2019 at 2:40 am

      Hi Patricia,
      Butter, or shortening, is an ingredient in rolled fondant, which keeps the fondant from drying out, allows it to be rolled easily, makes it easier to store for a period of time. Some marshmallow recipes include it, but it is not necessary, it is easy to do it without it. Some recipes will use a white vegetable shortening to prevent the color change, it is a choice. If you are storing it before using it then a slick of shortening will keep the surface pliable, when stored in an airtight wrap.
      If you are making it, and applying it right away then the butter/shortening is not necessary. Try it, even a sample, to make sure you are happy with it, that will be your best teacher!
      Thank you for your kind words, I hope you enjoy this recipe, and the process, it is satisfying!
      Gemma 🙂

  18. Nichole Sheffield on January 2, 2019 at 8:55 pm

    Hey Gemma I want to attempt to make my son a crayola box cake and it has fondant on it can I use this marshmallow fondant to cover the whole cake? and what kind of cake would you suggest

    • Gemma Stafford on January 3, 2019 at 4:54 pm

      Hi there, yes you can and i would suggest my funfetti birthday cake recipe, its one of my favorites! Enjoy and send my birthday wishes!

  19. JB on December 29, 2018 at 10:49 am

    I found this very difficult to make. Once the marshmallow started to cool it became very sticky and hard to work, consequently the mixer would have a tough time turning. I did eventually manage to get it to turn into fondant but it took along time.

    • Gemma Stafford on December 30, 2018 at 10:52 pm

      Yes this can be very sticky, great job!

  20. Yhe Ziadeh on December 15, 2018 at 2:25 am

    Hi Gemma
    Thanks for sharing this wonderful recipe though I feel intimated making fondant I still want to give this a shot
    Quick question can I grease the bowl before microwaving the marshmallow to avoid them from sticking?
    Thank you and have a nice day

    • Gemma Stafford on December 16, 2018 at 5:29 am

      Hi there,
      sure, but just the slightest slick of oil. You can oil your hands too when making this type of thing, it is a big help. Don’t be intimidated, make a little sample to see how it works for you,
      Gemma 🙂

  21. Leanne Krauss on December 10, 2018 at 2:38 am

    Hi Gemma

    I normally really dont like fondant , I find it tastes very plastic and that bad taste tends to linger in your mouth much more than the cake its self . That being said, I decided to try make my very own fondant using this recipe for my sons airplane birthday cake this weekend . I did not have high hopes…… but I was so happy with the results !!!!

    It tastes really good, was easy to use and there was NOTHING left after the people had eaten the cake ( normally at parties there is alot of fondant left on plates as people prefer to leave it and not eat it ) there was none of that . Cake was finished before I could blink .

    I only had a little challenge when I took it out of the fridge ( I made it 3 days before the cake ) and found that it was not the correct colour for my cake , tried to add some colouring , but it was a bit hard and needed to be manipulated a bit before I could work with it again, but that I’m assuming is to be expected when keeping it in the fridge .

    I’m very new to baking , but have found Gemma’s website so easy to use, and the recipe’s are so delicious

    THANK YOU GEMMA for making me a BOLD BAKER

    • Gemma Stafford on December 10, 2018 at 3:49 am

      Hi Leanne,
      Now I am doing my happy dance! Thank you for this, I am really pleased, especially from a novice bold baker, actually I think you are really observant. Store bough fondant is a great thing to have to hand, but it is designed for its appearance, not always to be eaten. I am so happy that this one worked out well for you, you have learned a lot,
      Gemma 🙂

  22. Susan Van stryp on December 6, 2018 at 7:24 pm

    Hey. Has anyone used home made marshmellow for the fondant?

  23. kcajandie on December 3, 2018 at 9:00 pm

    Hi Gemma,

    I am a big fan of yours! I made my very first marshmallow fondant in no time, thanks to you!

    I just have quick questions though.
    Where is the best area to store the marshmallow fondant and use it on a later date?
    Can it be stored in the refrigerator or in an open area/room temp.?
    How would you know if you cannot use it anymore? What are the signs?

    Your answers would be much appreciated.

    Note: I have made mine last Nov. 27. I have stored half of the fondant in the refrigerator with food colors and the half of it in a room temp. (hot weather) without food colors.

    Thank you and more power.


    • Gemma Stafford on December 4, 2018 at 10:21 am

      Hi there! Great questions. It will keep very well as long as it is covered in an airtight container. I usually keep it for up to 3 months in the fridge. When it is too old to use it will harden and be very stiff, no longer light and fluffy. Enjoy 😀

  24. Jackie on December 3, 2018 at 8:37 pm

    Hi Gemma,

    I am a big fan of yours! I made my very first fondant in no time. Thanks to you!

    Just have a quick questions though. How many days can I store the marshmallow fondant?
    Can I store it in the refrigerator or in a room temp.?

    More power to you!

    • Gemma Stafford on December 6, 2018 at 10:56 am

      Hi there, i would store it wrapped up tight in the fridge. Enjoy!

  25. Prateek on December 3, 2018 at 1:13 am

    Hi Gemma, could you please suggest some cakes that could be used under fondant?
    I know of pound cake, apart from that, what else can I use?

    • Gemma Stafford on December 3, 2018 at 6:29 am

      Hi there,
      Really any firm cake will take fondant. Here ( is a Victoria Sandwich. This is a moist but firm sponge. It is the one I use in the Crazy Cupcake recipe too. It can be flavored as you wish, coffee, chocolate,lemon drizzle etc.
      Try it, experiment, it is proportional too, and easy to remember if you measure with scales.
      I hope this is of help,
      Gemma 🙂

  26. Mafa on December 1, 2018 at 11:56 pm

    Hi ma’am
    How can we make this with out microwave oven ?

    • Gemma Stafford on December 2, 2018 at 5:20 am

      Hi Mafa,
      On the stove for this, really gently. Do not over heat the ingredients and keep on stirring.
      I hope this works well for you,
      Gemma 🙂

  27. Leigh Wolfsperger on December 1, 2018 at 8:22 am

    Hi! I used you buttercream recipie and it turned out great for my daughter’s cake, now Im wanting to use the easy fondant for my son’s.
    The questions I have is can I flavor this fondant? I have used store bought fondant and we all dislike the taste. Thank you! Leigh

    • Gemma Stafford on December 2, 2018 at 2:33 am

      Hi Leigh,
      you have hit on a good point. fondant is all about the look of it, the way you can decorate with it. If you are making a rolled fondant then you can easily add a few drops of peppermint, as you will find in some chocolate candies, or even fruit flavors. You could use lemon juice too in the making of it, but what matters is that you do not unbalance the recipe.
      You can experiment a bit with this, but the flavor should be in the cake, that will work best for you,
      Gemma 🙂

      • Leigh Wolfsperger on December 2, 2018 at 10:52 am

        I made the fondant, it is still extreamly sticky after adding the amount of powdered sugar you said, should i continue to add more until it gets more firm? Thank you for your help!

        • Gemma Stafford on December 5, 2018 at 9:57 am

          Hi Leigh,
          All things being equal, using the same ingredients as me, this should not need loads of extra sugar. Powdered sugar is highly absorbent, the slightest difference in the liquids will have a big effect.
          Now you need to keep going, add more sugar and knead it in.
          I hope this works well for you, I know, it is a tricky thing,
          Gemma 🙂

  28. Prateek on November 30, 2018 at 8:43 pm

    Hi Gemma, can I knead the fondant using stand mixer?

    • Gemma Stafford on December 1, 2018 at 2:57 am

      Hi Prakeet,
      Yes, on a low speed, for a few minutes. Add a little more icing sugar/powdered sugar if you need to to get the texture you want,
      Gemma 🙂

      • Prateek on December 3, 2018 at 1:11 am

        I came across two problems
        1) My sugar didn’t dissolve completely, I could feel the sugar crystals while eating
        2) My fondant wasn’t stretchy enough, if I’d pull the fondant, it would break, unlike the store bought fondant which is pretty elastic
        So, what’s the solution here?

        • Gemma Stafford on December 9, 2018 at 8:14 pm

          Hi Prateek,

          Did you use a fancy marshmallow ir just generic standard marshmallows?


  29. Anandi on November 26, 2018 at 3:17 am

    Hi Gemma my 9year old sis birthday is coming on 9 December so can u suggest me some beautiful birthday cakes ???? for which would be better for her age

    • Gemma Stafford on November 26, 2018 at 4:47 pm

      Hi there! This is a great one, Enjoy!

    • Geoff Foden on December 3, 2018 at 1:42 pm

      Hey – it’s my son’s birthday on the same day 🙂
      I am inspired however, to make this icing – practice with it and perhaps be Cake Dad 🙂

      • Gemma Stafford on December 3, 2018 at 3:34 pm

        Hi Geoff,
        Yes, do try it, it is perfectly possible,
        Gemma 🙂

  30. Emmanuel Orihuela on November 11, 2018 at 10:14 pm

    Hello. I was wondering if I could use a hand mixer instead of a stand mixer. Would that work?

    • Gemma Stafford on November 12, 2018 at 10:44 am

      Hi, as the marshmallow is very hot i would suggest using a stand mixer for safety. Great question!

  31. Diana on October 31, 2018 at 9:22 pm

    Hi Chef Gemma! I made my first ever fondant cake using marshmallows. And it’s sticky. But I like it. More practice needed. Thank you ????

    • Gemma Stafford on November 1, 2018 at 8:27 am

      Delighted you liked it, Diana!! Next time add more powdered sugar if you feel it needs it.


  32. Helena Figueiredo on October 28, 2018 at 4:33 am

    Hello Gemma, sorry for troubling you.
    I need your advise “urgently”. 🙂
    It´s my granddaughters birthday party on saturday. Yesterday I made a batch of marshmellow fondant, but feel its very dry.
    1- When we add little water, we knead the paste, but don´t add any more sugar, right?
    2- How much glycerin can be added?
    Thank you for your help. 🙂
    Best regards,

      Hi Helena,
      I think you need to microwave it for a few seconds to soften it out, then use oil on your hands to get it to come together. Water is never a good idea for this type of thing. You need either glycerin/oil/crisco to help, but very little.
      I hope this is of help to you,
      Gemma 🙂

    Hi Gemma

    Your biggest fan in South Africa. I wanted to ask you, can I use your mashmallow fluff for mashmallow fondant? Mashmallows are expensive here and they are usually two colours in a bag. Making fluff was cheaper for me. Thank you

    • Gemma Stafford on October 25, 2018 at 2:50 am

      Hi Mabel,
      Yes, you can do that. You will need to add sieved powdered/icing sugar to the fluff, carefully, until it comes together in a clean ball. Then it is kneadable. Pop it out on to the table using icing sugar to help knead and roll it.
      Thank you for being in touch from your lovely country,
      Gemma 🙂

    Good day to you Gemma! Thank you for sharing your amazing baking skills to the world, especially this video and recipe about fondant it pushes me to try it out, however as I made it, I discovered that my fondant became sweaty, I made my fondant 2 to 3 days before I rolled it out on my chocolate cake then I refrigerated it thinking I could preserve it that well, the next day when I excitedly preparing to decorate I saw my cake sweaty inside the fridge,I took it out worried if my buttercream icing can hold it while still sweaty, eventually I put it inside the fridge again before my niece can blew her candle on top of it. The cake looks good seeing it on far but closer look the sweaty fondant exudes her beauty, please tell me what did I do wrong on the process of keeping my fondant next time not to be sweaty, and how can I properly store fondant? God bless you Gemma! Thanks in advance for your response.

      Hi Gina,

      Sorry for my late reply. Really glad you like my recipes.

      I’m going to have to research this Gina because I’m not really sure as to why that happened. I have heard another person mention it before a while back.

      The only thing I can think of is that possible it was the moisture in the buttercream.

      Let me think on it,

    • Trish on October 29, 2018 at 8:12 am

      It’s because you refrigerated. I have to decorate my fondant cakes on the day

  35. BRYAN on October 1, 2018 at 7:45 pm

    Hello Miss Gemma… I watched almost all your videos in youtube. I say im a big fan. I badly need your help. Plsssssssssss…What to do to or what to add if I want a marshmallow fondant to be more elastic. People I know can cover a 9×4 and 7×4 2 tier cake with a Marshmallow Fondant recipe (4 c marshmallow : 4 c pow sugar.(roughly) Water and shortening). Pls pls pls. They wont tell me how to do it.

    Thank you!!!

    • Gemma Stafford on October 2, 2018 at 2:28 am

      Hi Bryan,
      Fondant can be a tricky thing. Do not over wet this as it makes it difficult to handle. The little oil/shortening, for your hands, works into the fondant to keep it smooth and pliable. In trouble, then a touch of glycerin will work its magic.
      If the fondant stiffens up pop it into the microwave for a few seconds, 5 – 10 seconds, this will really help with rolling it out.
      I hope this is of help. Get this right one time and it will always be good, then you can spread the word 😉
      Gemma 🙂

    Hi Gemma,
    can I use marshmellow of your own recipe ??you uploaded marshmellow recipe without corn syrup and you uploaded another recipe of fondant with corn syrup.
    I’m confused which recipe to follw because corn syrup and marshmellows are not easily available in maket.
    can you please tell me if I follow this recipe or making fondant and using marshmellow(made by your own recipe of marshmellows without corn syrup)?? icing suger is just powder suger?

    • Gemma Stafford on October 1, 2018 at 11:27 am

      Hi Yusra,
      If what you want is fondant then do not go to the trouble of making marshmallows.
      Here is some information which will help you. This will tell you what each of the ingredients will do in fondant, so it is easier to substitute.
      Powdered sugar is made up of sugar crystals. When you make a paste with them they will form even bigger sugar crystals, unless you do something to stop that process. Gelatin helps by preventing the crystals from forming and will give the fondant elasticity and structure.
      Glycerine, technically glycerol, is what’s known as a sugar alcohol. (Used now as a sugar substitute along with things like stevia and monk fruit, where it has a different purpose). Glycerin is sweet-tasting and like any alcohol it is a solvent. Glycerin helps keep sugar crystals from forming and breaks them down a little as well. Yet glycerine does far more than that in a fondant. Glycerin is also moisture retaining, and this explains why you find this as an ingredient in cosmetics too.
      In fondant glycerin traps and holds the moisture, but sugar is in fact one of the best known hygroscopic substances (water retaining) in the pantry. You will know this if you live in a humid place, and it is why cornstarch is added to powdered sugar to keep it dry.
      You don’t want the sugar to absorb moisture from the air, since water is also a solvent and will eventually make your fondant sticky and unmanageable. Glycerine keeps a rolled fondant firm and elastic by trapping and holding the moisture before the large sugar crystals can form to crack the fondant.
      A little light vegetable oil can help here, especially on your hands when making and rolling fondant.
      I hope this will help you, fondant is a tricky thing, try a little sample size at first.
      Gemma 🙂

  37. Vanessa on September 28, 2018 at 5:47 pm

    Thank you for making all of these videos. I love your recipes. I want to use this one to make my kids birthday cakes. I want to make some cut out shapes/figures ahead of time because I have a lot to do. How far in advance can I make my shapes and figures and how can I store them so they don’t become too hard? I’m thinking about starting on them maybe 4-5 days in advance, but am worried about them becoming too hard or inedible if I do this.

    • Gemma Stafford on October 1, 2018 at 11:17 am

      Hi Vanessa,
      I think you can happily make this 4 – 5 days in advance. do not refrigerate it, but rather keep it well wrapped in a cool dark place. If it feels hard to roll on the day you can pop it into the microwave for a few seconds, WATCH it, a little will do it, all will be well.
      I hope you have a lovely party,
      Gemma 😉

  38. Laura on September 26, 2018 at 4:18 pm

    Hello! Thank you so much for sharing your knowledge with us!! I want to decorate a store bought cake but I have never used fondant before, can I make the shapes/sculpt out figures a week ahead, And place in plastic bag? Is it supposed to harden? Also I have heard gel food coloring is better than the regular food coloring does this matter?

    • Gemma Stafford on September 29, 2018 at 5:51 pm

      Hi Laura,

      yes you can make your figures a week in advance. they are suppose to harden so that’s fine. gel is better because it’s more concentrated.

      Hope this helps,

  39. Macy Jackson on August 22, 2018 at 6:55 am

    Hi! I really would like to to try this for my daughter’s birthday. Can this recipe is enough to cover 9inch round cake?

    • Gemma Stafford on August 23, 2018 at 7:10 am

      Hi Macy,
      I used this on a three layer 6 inch cake, and it was perfect.
      This recipe yields about 26ozs of fondant. Depending on the depth, layers etc you will probably need about 40 ozs of fondant. This is a bit like ‘how long is a piece of string’ as it is also about how you roll it and how you apply it too. A buttercream crumb layer will be good for this, gives a smooth result and provided the filling.
      It is work running a little trial for this, perhaps 1/4 of the recipe to see how it works for you.
      Gemma 🙂

  40. Sarah on August 21, 2018 at 7:39 pm

    Hi Gemma,
    I’m excited to try this for my daughters birthday cake! But I’m still trying to figure out the filling for her cake. Have you ever refridgerated cakes with the fondant on it and had success? Was thinking of a cream filling but wasn’t sure if I needed to keep it to a filling that didn’t have to be refridgerated if I shouldn’t refridgerated it with the fondant on.

    • Gemma Stafford on August 22, 2018 at 2:13 am

      Hi Sarah,
      Fondant will take refrigeration, but after it is chilled it may sweat when removed to a very warm room.
      What you fill the cake with depends on the type of sponge you use. A very light sponge, like a Genoise/egg sponge loves a fresh cream filling, particularly with a layer of good Raspberry conserve. This is a really light cake, with little, or no, butter. The challenge then is to apply the heavy fondant. A butter type sponge, like a Victoria sponge ( as in this recipe, will take the fondant well, and a buttercream will be great for this, also loves a layer of jam. The beauty of this is that you can apply a crumb layer of buttercream, this allows the fondant to sit beautifully on the cake, will be great refrigerated, but will stand a cool room temperature. Anything over about 20c will begin to cause a problem if left too long. A Swiss meringue buttercream will hold up well too.
      I hope all goes well for you, we wil lbe waiting to see the results,
      Gemma 🙂

    Thank u gemma ur the best will continue to follow you if I can post pictures I will show u

    • Gemma Stafford on August 8, 2018 at 9:19 am

      I would love to see photos of what you make 🙂

  42. Donna Kemp on August 3, 2018 at 11:23 am

    Hi gamma I watch all your videos on Facebook I love your recipes on the fondant what kind of unflavored oil would u recommend

    • Gemma Stafford on August 3, 2018 at 2:54 pm

      Hi Donna,
      Really a light vegetable oil, a sunflower oil would be good, or a light flaxseed oil. You can judge by the color, very light yellow.
      Gemma 🙂

  43. dhar on August 2, 2018 at 7:06 pm

    hi gemma, i love watching all your videos..i want to make this marsmallow fondant but i dont have microwave oven..what is the option..thanks in advance

    • Gemma Stafford on August 3, 2018 at 2:14 am

      Hi Dhar,
      Use a double boiler. That means a heatproof bowl over a pot of simmering water. do not allow the bowl to touch the water, and keep it simmering, not boiling rapidly. you can use this technique for all sorts of delicate things, melting chocolate, making emulsion sauces, dissolving gelatin etc.
      I hope this helps,
      Gemma 🙂

  44. J_dog on July 30, 2018 at 5:52 pm

    Gemma if we don’t have marshmallows, (not that i don’t have any) what can we replace it with,

    • Gemma Stafford on July 30, 2018 at 6:06 pm

      Hi Janice,

      unfortunately for this recipe you need marshmallows. If you want you can always make this fondant


  45. Mel on July 19, 2018 at 6:56 pm

    Do I use pure icing sugar or can I use icing sugar mixture? And will this make enough to cover a 25cm cake? Thanks 😀

    • Gemma Stafford on July 20, 2018 at 10:08 am

      Hi Mel,
      An icing sugar/powdered sugar mixture has a touch of cornstarch added in order to keep the powder dry. This is good to use in any recipe really, it is pretty much standard.
      For frosting it is particularly useful, as it is important to keep it dry.
      I hope this is of help,
      Gemma 🙂

  46. Lisa Humphreys on July 19, 2018 at 6:50 pm

    Hello Gemma!!! I love your videos and use so many of your recipes! Thanks!
    I tried making this tonight for my sister’s 60 birthday cake but it is so loose. The recipes calls for 4 tbls if water which seemed like a lot. Is that a typo? With all the icing sugar in the mixing bowl, it’s still liquid. Thanks!

    • Gemma Stafford on July 21, 2018 at 2:04 pm

      Hi Lisa,

      Really glad you like my recipes. So I just looked at the recipe and although I didn’t find it wet I reduced the water just incase anyone else has the same problem. I hope you were still able to salvage your fondant.


  47. Tonya on July 17, 2018 at 9:11 am

    Hi gemma
    I have tried to make marshmellow fondant in the past and after rolling it out it is so sticky still that I cant get it to the size i need. I have tried making sure there is enough powdered sugar down so it wont stick but it is not working. What am i doing wrong?

    • Gemma Stafford on July 19, 2018 at 10:06 am

      Hi Tonya,

      It sounds like maybe your fondant you needed to add more powdered sugar when you were mixing it. I’m going to write a note in the recipe that if your dough isn’t firm like mine, add more sugar.

      I do my best to give very precise recipes but with a global audience and different brands of marshmallows and sugar sometimes there is a difference.


  48. Jackie on July 16, 2018 at 1:25 pm

    Hi, can you freeze fondant?

    • Gemma Stafford on July 16, 2018 at 8:15 pm

      No, Jackie but it lasts for months in the cupboard.


  49. lucy on July 14, 2018 at 7:40 pm

    Cool recipe! The fondant turned out perfect, and we used it to create a brain cake. I will make other things with it.

    • Gemma Stafford on July 15, 2018 at 12:11 pm

      Yay!!!!! I’m delighted you liked this recipe 🙂


  50. Em on July 12, 2018 at 8:00 am

    Hi Gemma,
    There are colored marshmallow available in stores, can I use it instead of food coloring? Thank you!

    • Gemma Stafford on July 12, 2018 at 9:58 pm

      sure, it will be a very light color but you can try that. 🙂
