Hot Chocolate Mug Cookies for Two

Save Recipe

This Hot Chocolate Mug Cookie combines the flavor of a chocolate cookie and a warm cozy hot chocolate. Oh and its made in 2 minute in the microwave! 

Hi Bold Bakers!

When it gets cold in the winter time, I love a big mug of Hot Chocolate. And since it’s the holidays, I’m all about cookies. This year instead of making one or the other, you can make Hot Chocolate Mug Cookies and even share them with a friend or loved one. This treat is designed for sharing, and sure to please, so lets get micro-baking!

How to make a Hot Chocolate Cookie in a mug

My Hot Chocolate Mug Cookies are really the best of both of these treats. Think chocolate cookie meets melted foamy marshmallows. Leave the store bought cookies where they are, and surprise that special person in your life with this perfect treat. Combine a few ingredients you most likely already have, to create the chocolate cookie part of this mug cookie. Then, just as with hot chocolate, top this mug cookie with mini marshmallows and microwave for just one minute.

Do marshmallow melt in the microwave?

The best part of this Hot Chocolate Cookie in a mug is obviously the generous amount of melted toasted marshmallows that top the whole thing off. Marshmallows melt perfectly in the microwave creating that warm fluffy marshmallow fluff texture we all know and love in a hot chocolate.


You will not believe how good these Hot Chocolate Mug Cookies are and the best part is that this recipe is designed for sharing. This is the perfect little dessert to end any holiday celebration so I can’t wait for you to give it a try!

    Does it work without baking powder?? or maybe that is the difference between cookie in mug and cake in mug – ?
    I am addicted to your videos. And as soon as I have my new kitchen, my family is going to get really FAT!! 😀

    • Gemma Stafford on June 13, 2019 at 8:19 am

      Hi Lenka,
      Haha, as we say in
      Yes, that is exactly the difference in this recipe, generally, cookies do not have a raising agent, nor will brownies and blondies.
      Good question!
      Gemma 🙂

  2. Liv on March 1, 2019 at 8:29 am

    What kind of flour did she use. Self raising or plain?

    • Gemma Stafford on March 1, 2019 at 1:08 pm

      Hi, i used all-purpose.

  3. WK on October 12, 2018 at 10:20 am

    Made it. Disappointed. Its like cake. Definitely not a cookie!

    • Gemma Stafford on October 13, 2018 at 2:39 pm

      I’m sorry to hear you didn’t enjoy it. These do micro-bake up like cookies. Were you able to follow the recipe exactly?

  4. Valerie on October 11, 2018 at 9:31 am

    Absolutely loved this! A primo chocolate fix.

    I’ve made it twice so far and can already tell that it’s going to become one of my go-to recipes for those times when I just have to satisfy a chocolate craving. The second time I made it I added some chocolate chips, and will continue to add a few chocolate chips from now on.

    Thanks for such an awesome recipe Gemma!

    • Gemma Stafford on October 13, 2018 at 8:43 pm

      I LOVE to hear that!!!! Thanks for trying it out 🙂


  5. Kou on April 23, 2018 at 5:59 am

    I tried baking this with hot cocoa mix and they tasted great! This was the first ever mug cake which i made succesful! Thank you for the amazing recipe! 🙂
    I only added a small amount of sugar tho? But adding melted marshmallows definitely enhanced the sweetness of the cake!

    • Gemma Stafford on April 24, 2018 at 2:48 am

      Hi Kou,
      Good idea! Well done you. Yes, adjusting the sugar when adding the sweet marshmallow was clever, and the right thing to do. Thank you for being in touch,
      Gemma 🙂

  6. Ayuki on April 23, 2018 at 1:32 am

    Hi hi can i use hot cocoa mix instead? But what ingredients do i need to take out?

    • Gemma Stafford on April 23, 2018 at 2:57 am

      Hi there,
      This has been sweetened, and will have other ingredients too. Adjust the sugar a bit, but you need to experiment with this, it is a different thing,
      Gemma 🙂

    I made this with my grandchildren. It is an easy recipe to do with kids. They put peppermint marshmallows on top. Yummy!

    • Gemma Stafford on January 18, 2018 at 7:44 pm

      Delighted to hear that Molly 🙂

  9. Janet Sager on January 18, 2018 at 9:50 am

    Hi Gemma,
    I am going to present a workshop on microwave snacks for a 4-H Regional Energizer. Will be working with 4-H’ers from 8 to 18 and would like your opinion on what two or three snacks I should use for the workshop. Of course healthy snacks is the main focus for this group. Thanks for your opinion.

    • Gemma Stafford on January 18, 2018 at 8:06 pm

      Hi Janet!!

      Show them the potato chips, kale chips and my microwave popcorn. All recipes are on my site 🙂

      I hope they like them.

    Hi, Gemma, just discovered you on YouTube! I love your recipes and plan to try this one soon. I’ll substitute Splenda for white sugar but the “fake” dark brown sugar is icky. Any other substitute that won’t change the flavor profile?

    • Gemma Stafford on January 7, 2018 at 3:53 am

      Hi there,
      Yes, I hear you. The thing to remember about sugar substitutes that there are ‘horses for courses’ as we say in Ireland.
      Splenda/xylitol are great, and work well in baking, but they have some limits, as they will not caramelize, so you need to consider this too when baking cookies in the oven for instance. ( here is my way to make brown sugar. Molasses in small amounts seems to be a safe and acceptable thing, and I urge you to research this a little. Other than that proceed with the splenda, and do not worry about it,
      Gemma 🙂

    I found you on youtube.i really enjoy your videos..

    • Gemma Stafford on December 19, 2017 at 1:56 am

      Hi Jolene,
      Thank you, that is very kind, I am happy that you are here with us,
      Gemma 🙂

  12. Ian on December 14, 2017 at 3:30 pm

    Can I make these ahead

    • Gemma Stafford on December 15, 2017 at 4:34 am

      Hi Ian,
      This recipe is a good one to make ahead, because it does not contain any baking powder/raising agent. Brownie type recipes work well too. When there is a raising agent it can be spent before you get a chance to bake, so making ahead is not so good, but you are good to go for this recipe,
      Gemma 🙂

  13. MadaAbuAyyash on December 7, 2017 at 9:31 am

    Looks yummy 👌
    Can I bake it in a toaster oven?
    If yes.. what is the time needed?
    Thank you Gemma

    • Gemma Stafford on December 8, 2017 at 4:20 am

      Hi there,
      Yes, this recipe wil lwork well in a toaster oven. Use a muffin pan, not a mug, and bake at 180C/350F for about 15 mins.
      Gemma 🙂
