3 Layer Cake made in the Microwave!!! You won't believe how soft and moist this cake is that was made in a microwave

3 Layer Cake Made in the Microwave

Save Recipe

Hi Bold Bakers!

I have been inspired by all of you to bake a full-size 3 Layer Cake Made in the Microwave. Yes, you heard me right!  Microwave Baking, or what I call “Micro-baking” is my thing. As you all know I am no stranger to Microwave Mug Cakes, or Microwave Mug Meals. If you can eat it, I can make it in a mug in the microwave. From more mug cakes than you can imagine to microwave snacks like Microwave Potato Chips, I have never been afraid of using my microwave to the max. But this time is different! I’m making a full shebang, bells, whistles and all,  full size, 3 Layer Cake Made in the Microwave!

I love creating recipes for the microwave. I know from listening to you, that not all of you out there have a full kitchen including an oven. And I know you sometimes want an amazing dessert fast.

So I decided to go extra Big and Bold this time and trade in my mug for full-sized Silicon Cake Molds. This means that after mixing up my Best Ever Funfetti Cake batter, I simply divided it between my 3 microwave safe cake pans, and set the timer to 2:30 minutes. Even I could not believe how perfectly baked these cakes came out after such a short time in the microwave. And of course, this is the perfect cake for my Best-Ever Buttercream Frosting recipe.

This means next time you want to make a cake for a special occasion, or just feel like you need that sweet slice, you can have one in minutes instead of hours. Honestly, you have to see this for yourself. Who wouldn’t want to go from zero to Funfetti in under 10 minutes? I can’t wait for all of you to give this microwave cake recipe a try!

Servings: 10 -12
Author: Gemma Stafford
Ingredients
  • 3 ⅓ cups (1lb 1oz/ 500g) all purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 ½ cups (12oz/355g) sugar
  • ½ cup (3oz/90g) light brown sugar
  • 1 cup (8oz/240g) butter, melted
  • 2 large eggs
  • 2 cups (16oz/480g) Buttermilk
  • 1 tablespoon vanilla extract
  • Buttercream Frosting
  • cup (3oz/90g) sprinkles
Instructions
  1. In a large bowl, mix together flour, both sugars, baking powder, baking soda, and salt. Set aside.
  2. In a large microwave-safe bowl, melt butter in the microwave.
  3. In a separate jug, whisk the egg, buttermilk, and vanilla extract until combined.
  4. Stir in buttermilk mix into the dry ingredients, followed by the butter until no lumps remain. The batter will be thick.
  5. Lastly, stir in sprinkles, but do not overmix because the sprinkles will bleed their color.
  6. Divide the batter evenly between 3 silicon microwave safe cake tins.
  7. One at a time microwave each cake for 2 minutes and 30 seconds. Remove from the microwave and allow to cool before turning out. (this cook time is based on my microwave which is 1200Watts so your cook time may vary)
  8. Once cooled turn each cake out out and level the tops.
  9. Frost cooled cake: Start by frosting a thin ‘crumb layer’ with my Best Ever Buttercream Frosting recipe. Chill for 30 minutes to set the frosting. Once that layer is set apply a second layer of thicker frosting
  10. Decorate as desired with sprinkles. There may be leftover frosting depending how much you wish to use.
  11. Cover cake and store at room temperature for up to 7 days. Enjoy!

      Yes, you can! Great idea!

  2. Michelle Gertrude Aricha on November 12, 2018 at 11:06 am

    I did the 3 layerocrowave cake. This is my first time in my life to bale anything. I didn’t have frosting or anything but the cake is beyond delicious and moist I cannot believe I have never naked in my entire life! Thanks Gemma. Now I’ll be baking every week using your different recipes. This is the best website I’ve ever come across. Wow.

    • Gemma Stafford on November 13, 2018 at 2:55 am

      Michelle, you have lifted my spirits! YEA, well done you. This is what I love to hear, brave effort well rewarded.
      Thank you for this lovely review, I appreciate it,

      Gemma 🙂

  4. Mary on November 2, 2018 at 6:16 am

    Hi I don’t like butter what can I use instead

    • Gemma Stafford on November 3, 2018 at 6:04 am

      Hi Mary,
      You can use a little oil, about 1/3 less than the butter quantity, butter is more than fat!
      Gemma 🙂

  5. Keren on November 1, 2018 at 3:02 am

    Hi Gemma am in Africa and don’t know where to get butter milk what can I use as a substitute

    • Gemma Stafford on November 1, 2018 at 8:47 am

      Hi Keren,

      You can also mix yogurt with milk and that will work. Also you can make your own really easily

      Best,
      Gemma.

  6. Nurdiniyati Burhanudin on October 26, 2018 at 6:29 am

    Hey Gemma!
    Just made this cake today for my husband’s 40th birthday! Along with your amazing crazy chocolate buttercream frosting. Didn’t have silicon moulds so I used my glass casserole bowl instead. They turned out amazingly delicious! Even my pro-baker neighbour said it was perfect! Thanks Gemma for all the great tips

    • Gemma Stafford on October 27, 2018 at 7:35 am

      I’m so happy to hear it. Well done to you, and I’m delighted everyone enjoyed the cake. Thank you for being part of the Bold Baking Community! #BoldBaker

  7. Rosemary on October 24, 2018 at 10:50 pm

    Gemma how long does this cake last and what preservatives can I add to it

    • Gemma Stafford on October 25, 2018 at 2:39 am

      Hi Rosemary,
      This type of cake will last well for a day or two.
      Generally we do not add preservatives to home baked goods. We rely on good ingredients to hold them for a few days. If you need to keep it longer you can freeze it. All baked goods are best stored in an airtight container in a cold place. Baked goods for sale and supply come under different regulations here in the US and in other places.
      Thank you for being in touch,
      Gemma 🙂

  8. Gloria L on October 24, 2018 at 1:24 pm

    I have a 9 inch square silicone cake pan and I would like the make one of your microwave cakes can you give me directions please?

    • Gemma Stafford on October 25, 2018 at 5:45 am

      Hi Gloria,
      This batter finishes at about 8 cups, which would be good in a single 9 inch square pan. The issue for you may be in the baking. That is not the best shape for microwave baking, though it does depend on the type of oven you have. There are too many variables for me to be sure about this, you would have to try it, I am sorry,
      Gemma 🙂

  9. LISA WOOD on October 22, 2018 at 2:47 pm

    HOW DO YOU MAKE ICING FOR THE YELLOW CAKE MIX PLEASE….THANK YOU…….:)

  10. Bonnie on October 22, 2018 at 3:22 am

    Lovely cake! I was wondering if you have a chocolate version being the chocolate person I am!
    Bake on!

    • Gemma Stafford on October 22, 2018 at 3:41 am

      Hi Bonnie,
      Thank you for your kind words. You can make this into a chocolate cake, easily! Remove one tablespoon of flour and add two tablespoons of cocoa, sieve it in with the flour, and as we say in Ireland ‘bob’s your uncle’ haha, chocolate cake for you!
      Gemma 🙂

  11. Melissa on October 15, 2018 at 2:14 pm

    Hi Gemma. Will this cake stand up to fondant icing? My oven is broken but I promised to make a specific cake for my grandson’s birthday. Thanks!

    • Gemma Stafford on October 17, 2018 at 7:40 am

      Hi Melissa,
      Yes! this will stand up, it is quite a firm cake.
      I hope your grandson has a great birthday,
      Gemma 🙂

      • K’Tie on November 27, 2018 at 1:27 pm

        If one doesn’t have a microwave can you still do the old fashioned way in the oven? Sorry if this is a dumb question I just want to be sure:(

        • Gemma Stafford on November 29, 2018 at 8:22 am

          Absolutely. Bake at 350oF (180oC) for about 25-35 minutes.

          Best,
          Gemma.

  12. Diksha on October 13, 2018 at 9:47 am

    Seems delicious recipe and super easy …..jus wana know the substitutes of egg which can be used in microwave…also does egg replacement powder works in microwave?thanks in advance

  13. GrannyGwen on October 12, 2018 at 5:12 pm

    I made your microwave carrot cake and it was superb. Then my microwave died and the salesman talked me in to getting a new one without a turntable. I can’t microwave a cake any more. I have tried again today and cooked it for an extra 2 minutes as it is 1000 watt. The outside,of the cakes are lovely but the mixture in the centre is still uncooked. I will use a cookie cutter to remove the centre and put something exciting in the middle. BUT ……… Do you have any ideas please?

    • Gemma Stafford on October 13, 2018 at 8:55 pm

      Oh gosh, Gwen that’s a tough one because the turn table usually helps with even cooking. Maybe you will need to turn your cake around 1/2 way though the cooking process. You might also need more time then I did.

      Hope this helps,
      Gemma.

  14. Seasons01 on October 11, 2018 at 8:47 am

    FYI – this has a different tecture then most cakes and bakes with a slight crust. Note that when you refrigerate left over the cake will be hard the next day. Make sure you take out in advance of eating. The butter that is used hardens the cake.

    There was not enough vanilla flavoring but I think that was my daughter not using enough. It says 1 tbls and I’m thinking my daughter used much less.

    My family said it was good but I didn’t get a request for another one like this.

    • Gemma Stafford on October 13, 2018 at 8:47 pm

      Thanks for your comments. Yes, feel free to add in a little more vanilla. I’ll check the recipe and maybe bump it up.

      Really glad you tried it as it’s one of the most popular cakes on my site.
      Gemma.

  15. vrushali on October 4, 2018 at 8:10 am

    Hi Gemma,
    Can I omit brown sugar and use white instead??

    • Gemma Stafford on October 5, 2018 at 7:25 am

      Hi there,
      Yes, that will be good,
      Gemma 🙂

  16. Namita on October 4, 2018 at 3:54 am

    Hi Gemma thanks for this recipe .I just want to ask can I use oil instead of butter or half oil and half butter .

    • Gemma Stafford on October 4, 2018 at 6:32 am

      Hi there,
      yes, but I have not done so and it will be an experiment. Choose a light vegetable oil for best results. alternatively choose a block of vegetable margarine which is easy to treat as butter in a recipe.
      Thank you for this question,
      Gemma 🙂

  17. Aparna on October 3, 2018 at 7:03 am

    Hi Gemma, I would like to know wat would be the proprtion of the ingredients, just to make one layer of the cake.

    • Gemma Stafford on October 4, 2018 at 5:59 am

      Hi there,
      That is a math question!
      It depends on the size you want. This cake is in 3 x 6 inch pans, but you can make it in 3 x 8 inch pans too, though it will be a thinner cake but it will be good. You have to divide the recipe by two or three according to the size of the pans. I would do this for you but as you know the way you measure your ingredients it will be easier for you.
      I hope this is of help,
      Gemma 🙂

  18. Yasangi Niluka Siriwardana on September 22, 2018 at 5:04 am

    I made this with half of the given amounts to celebrate 3months day of my baby boy. Very easy and great soft texture and it yielded about 12 small servings. Great recipe as always Gemma. Thanks heaps and much love from all of us!! Just want to know whether I can replace about 2 tablespoons Of flour with cocoa powder and may be add a splash of milk to bake a chocolate cake. TIA.

    • Gemma Stafford on September 22, 2018 at 9:10 am

      Hi there,
      good job, well done you. Cocoa is a really light thing, omit one tablespoon of flour and add 2 tablespoons of sieved cocoa. That will do it for you.
      I hope this is of help,
      Gemma 🙂

  19. Suyin on September 21, 2018 at 11:07 pm

    Hi Gemma, can you use the 3 layer confetti mix for microwave cupcakes? Kind regards Suyin

    • Gemma Stafford on September 22, 2018 at 1:28 am

      Hi there Suyin,
      Sure you can. If you have the right mold for these. The baking time will depend on the size and the number in the oven. You wil lhave to monitor them, and remove the ones which bake ahead of others. It will be FAST!
      Gemma 🙂

  20. Darlene Fabrizi on September 19, 2018 at 12:24 pm

    Can I use this same recipe and bake it in oven?

    • Gemma Stafford on September 20, 2018 at 7:22 pm

      Yes you can. Bake it at 350oF (180oC) for roughly 40 minutes 🙂

      Best,
      Gemma.

  21. Rachel on September 18, 2018 at 8:55 pm

    Hi, Gemma! Thank you for this recipe, it’s such a great idea! Funfetti is my favorite kind of cake! I am going to make this for my birthday. What size of cake pans did you use for this? Can you use regular cake pans? Thank you!

    • Gemma Stafford on September 19, 2018 at 1:35 am

      Hi Rachel,
      Good! that is the idea, get baking.
      The microwave will now accept any metal, the waves cannot penetrate and the magnetron may be damaged.
      3 x 8 inch pans, or 3 x 6 inch pans will work well here. Two 9 inch pans too.
      Glass oven ware will be good, and paper pan liners will help too. Test the recipe through the bake, ovens vary. When it feels barely firm to the touch on top it is baked.
      I hope this works well for you. You can try an experimental one first by dividing the recipe as close as possible in 1/3 and using one pan.
      Gemma 🙂

  22. Ameerah on September 18, 2018 at 3:26 pm

    Hi Gemma, hope you well. I absolutely love love your videos. I was so glad to see that someone made a video tutorial with a 3 layer cake that can be made in a microwave oven. I’d like to know how can I make this into a chocolate version?

    Another question, can any cake recipe be baked in a microwave?

    Thanks

    • Gemma Stafford on September 19, 2018 at 7:48 am

      Hi Ameerah,
      There are a number of cake recipes designed for microwave baking, but it does not mean that they can all be baked in this way.
      The recipe here is easily adapted to different flavors, and the addition of 2 tablespoons or so of cocoa would make a chocolate cake of this one. Equally the frosting can have cocoa added or even melted cooled 70% or so chocolate.
      The red velvet version is here too, and that is really a chocolate cake, colored and slightly spiced.
      Reading through the recipes will help you to understand what you can do with the ingredients, have fun!
      Check out the mug recipes too, a great way to try things.
      Gemma 🙂

  23. Gabriela Ioan on September 10, 2018 at 6:20 am

    Va urmaresc cu admiratie din Romania.Am facut toate cele 3 torturi cu trei niveluri dupa retetele Dvs.Au iesit foarte bine.
    Ieri am facut tortul de morcovi care a iesit minunat.A diferit doar timpul de coacere,eu avand un cuptor cu 800w.Va multumesc mult pentru retetele minunate.Poate pe viitor un tort gingerbread,de ciocolata sau tort rainbow.Cu multa simpatie si respect.

    • Gemma Stafford on September 11, 2018 at 6:17 am

      Hi there,
      Bună,
      Iată o rețetă care vă poate plăcea prea mult, ar trebui să funcționeze bine la cuptorul cu microunde sau pe aragaz.
      https://www.biggerbolderbaking.com/gingerbread-pudding-cake/) acest lucru ar trebui să funcționeze bine pentru dvs. Vă mulțumim că sunteți în contact,
      Gemma 🙂

  24. Yuva on September 1, 2018 at 5:24 am

    Hi Gemma, I found your website very recently and I tell you it’s a fantastic job you are doing. I loved it so much especially the basic recipes. Very helpful. I have tried your ice cream recipes it’s all delicious. Am gonna try your microwave cake recipe. But the thing is I don’t use egg, so here I have to add 2 and half cup buttermilk, substituting 2 egg with 1/4 buttermilk.?

    Thank you!! Keep inspiring ❤️

    • Gemma Stafford on September 1, 2018 at 7:45 am

      Hi Yuva,
      thank you for your very kind words.
      If I were substituting eggs in a recipe where buttermilk was an ingredient I would choose a different sub. Alternatively use a little more baking powder, that may help.
      Applesauce/flax egg/chia seed egg would be good with this type of bake. Yogurt too.
      I hope this is of help.
      Gemma 🙂

  25. AparnaSantheep on July 12, 2018 at 12:52 am

    Dear Gemma,

    I have tried this recipe many times and it was a hit all the time..This time I got an order from one of my friends and it is was my first order. I baked your microwave vanilla cake and it was a huge hit again..Have added the picture..it was a flower basket cake.. Thank you so much for this wonderful recipe.. You ate doing a great job.. it is beyond words..

    • Gemma Stafford on July 12, 2018 at 2:05 am

      Hi there,
      I am really happy to hear this Aparna, thank you so much for letting me know.
      I will check out the photos right now, thank you for submitting that too.
      I deleted some photos in error a couple of days ago, I hope your was not among them, it was easily done, meant to press approved, so cross with myself as I love to see them, and for others to see them too.
      Good to have you with us,
      Gemma 🙂

  26. Denise on July 6, 2018 at 6:13 am

    Love, love, love the Microwave cake recipe, I most likely will never bake a cake in my stove ever again. This has work well for me to find another use for the Microwave oven. Great recipe. BTW I have used box cakes and they turn out perfect. Keep up the great work you are doing for us all. Denise

  27. Mayra on July 4, 2018 at 3:59 pm

    Does buttermilk have to be used?

    • Gemma Stafford on July 4, 2018 at 5:34 pm

      You can replace the buttermilk with regular milk, Mayra.

  28. Katherine doCarmo on July 1, 2018 at 9:35 pm

    Hi, Gemma.
    Bold Baker here. I love all the recipes I have tried before and just finished up using my sweetened condensed milk for my cold brew coffee and I will definitely be making more! I want to make this cake for 4th of July for a family picnic. Only problem is, I don’t have the silicone molds yet. What temperature would you recommend baking and the time on it? Thanks so much! 🙂

    • Gemma Stafford on July 2, 2018 at 2:20 am

      Hi Katherine,
      This is a basic enough sponge cake, it will bake at 180c/350f for about 25 minutes, but keep an eye on it, it depends on the pans you use.
      Brownies are good too for a picnic, and easy to transport, requiring no filling, so no worries about melting frosting.
      The Best Ever Chocolate Cake is also a good one,(https://www.biggerbolderbaking.com/best-ever-chocolate-cake/) the frosting is stable, and it will work well for you too, so lots of choices. Refrigerate it overnight for ease of packing.
      I hope you have a great picnic with your family, it is a great day,
      Gemma 🙂

  29. Jennifer on June 26, 2018 at 1:36 pm

    My 4yo and I LOVE making this cake. Have made it several times already- always with purple icing though – her favorite. I would love to try a chocolate version. How much chocolate should I add and do I subtract the same amount from the flour or leave that quantity the same? Thanks in advance.

    • Gemma Stafford on June 27, 2018 at 5:25 pm

      Delighted you like this recipe, Jennifer. 🙂

      I’ll definitely add a chocolate version to my list. It would be tricky to make this one chocolate because you would have to remove flour otherwise it will be dense. Leave it with me.

      Best,
      Gemma.

  30. Bold Baker on June 26, 2018 at 12:45 pm

    I loved it!!

  31. jojo42 on June 19, 2018 at 6:37 am

    Hi Gemma,i wanted to try your recipe to work out the timings in my microwave but didnt want to make the whole quantity and waste it.I cut everything down to a third.I didnt have brown sugar so used all white,i used self raising flour and had no baking soda so just added a little baking powder had no vanilla so added lemon extract.Also the reason for testing is i have no silicone baking tins or round bowls so used oblong plastic containers about 7×4.5. Well im so chuffed but absolutely gobsmacked! I’ve ended up with a 3.5 inch high cake which is so light and delicious. Im gobsmacked because i only used a third of your recipe.Did i do it right? Im going to use this recipe forever now instead of the oven its amazing.

    • Gemma Stafford on June 20, 2018 at 12:55 am

      Haha! Jojo, I had no idea where this was going! It was like a suspense novel, lol.
      I am really happy that you managed this, in your own way. I think the extra little baking powder gave you a very light result, well done you, I am glad there was a happy ending!
      Gemma 🙂
