Delicious hot chocolate cupcakes with a hot chocolate sponge, marshmallow frosting and more – my favourite hot drink in cupcake form!

If you have followed me for a while you will know how obsessed I am with hot chocolates. They are cosy, and heavenly, and because its the winter festive season I thought they were the perfect cupcake to celebrate with. 

Hot chocolates

Honestly, I started going to cafes purely for hot chocolates as one point because I was just obsessed. I adore them. It’s being cosy in a drink, and I just adore it! I was a regular at a few coffee shops and they learnt my hot chocolate order very quickly. 

I adore all sorts of hot chocolate whether they’re plain, mint, orange, hazelnut, gingerbread and so on. I just can’t get enough. My favourite one to make at home is anything whittard because they’re so so delicious. 

I generally find baking with hot chocolate fine, but as long as it’s a good quality one. I tend to stay away from cadburys as the flavour doesn’t translate in the same way – but whittard, green and blacks, etc all work wonderfully. 


For the cupcakes I followed the same idea as my normal chocolate cupcakes because it really is a simple switch. I say to use good quality hot chocolates or even high cocoa content ones because of the flavour and sweetness. A lot of hot chocolates have a tonne of sugar added in, and this can become too sweet. 

I use a simple chocolate mixture of butter, sugar, self raising flour, the hot chocolate powder and eggs. It’s super simple, but effective. It means that kids tend to absolutely adore them as well, so in the colder months it’s something delicious for them as well. 

I am the person that would drink a hot chocolate in the middle of summer though, so of course these beauties can be made whenever. 


This marshmallow frosting has become insanely popular. I can’t actually keep up?! I posted it first on my s’mores cookie recipe not so long ago and the amount of people who have made it now is mental! I wouldn’t necessarily call it a marshmallow fluff as its a meringue based frosting, but it tastes marshmallowy and delicious. 

I know it may read slightly terrifying, but it’s so easy to make. You want to make sure your egg whites have no egg yolk in, and you’re mixing the meringue in a super clean bowl with a super clean whisk. You can leave the mixer running whilst you make the sugar syrup, but if you don’t have a stand mixer, you can start to make the meringue towards the end of your sugar syrup boiling to temperature. 

I use a thermometer to make sure that my sugar syrup has got to the correct temp, and it’s so easy. Because the syrup boils to 113ºc you don’t have to worry about the egg whites being raw. Whisking in the sugar syrup slowly cooks the egg whites to safe temperature. 


I used my favourite piping tip as always to pip my frosting onto my cupcakes because it’s heavenly and just looks beautiful. I did carried away as I always do, but sprinkling on some extra micro mini marshmallows, a little dusting of hot chocolate powder and a small flake each finished them off perfectly. 

I wanted the decoration of the cupcakes to represent the look of a beautiful hot chocolate, and it worked wonderfully! Of course, if you wanted to be a bit more classic to the idea of hot chocolate, you can use whipped cream to decorate the cupcakes instead. I would whip up 450ml of double cream with 2tbsp of icing sugar to soft peaks and pipe that onto the cupcakes instead. 

Tips & Tricks 

These cupcakes will last for 3 days, but can freeze for 3+ months

The marshmallow is best used fresh, but can be kept for 2-3 days in the fridge and re-whipped before use.

  • 175 g unsalted butter (room temp)
  • 175 g light brown soft sugar
  • 135 g self raising flour
  • 40 g hot chocolate powder
  • 3 medium eggs

Marshmallow Buttercream Frosting

  • 3 medium egg whites
  • 100 g caster sugar (for meringue)
  • 1 tsp vanilla extract
  • 100 g caster sugar (for syrup)
  • 65 ml water


  • mini marshmallows
  • flakes
  • hot chocolate powder



  • Preheat your oven to 180ºc/160ºcfan and line a muffin tray with 12 cases
  • Add the butter and sugar to a bowl and beat together until creamy
  • Add in the self-raising flour, hot chocolate powder and eggs and beat until smooth
  • Split between the cases and bake in the oven for 19-21 minutes until cooked through
  • Leave to cool on the side.

Marshmallow Frosting

  • Add the egg whites to a large bowl and start to whisk to stiff peaks
  • Add the 100g of caster sugar, 1 tsp at a time, whilst whisking.
  • Once all the sugar is in, whisk in the vanilla and leave the meringue to whisk on a slow speed just to keep it moving and stop it from sitting.
  • Whilst this is whisking, add the other 100g of caster sugar to a pan with the water. Heat this on a low heat to dissolve the sugar. 
  • Once the sugar is dissolved, turn up the heat and boil the mixture to 113ºc. 
  • Once heated, turn the whisk up high again and trickle the syrup into the meringue to make the marshmallow. Once all the syrup is in, whisk for a further 5 minutes. 


  • Pipe your marshmallow frosting onto the cupcakes however you fancy (I used a 2d closed star piping tip!)
  • Decorate with mini marshmallows, a flake, and a dusting of hot chocolate powder


  • These cupcakes will last for 3 days, but can freeze for 3+ months
  • The marshmallow is best used fresh, but can be kept for 2-3 days in the fridge and re-whipped before use.

    When you say they can be frozen . Is that with the marshmallow topping on?

  2. Carol Sammon on March 16, 2024 at 12:13 pm

    How can i make the frosting chocolate?
    Can i add cocoa powder?

  3. rachel on November 26, 2023 at 1:39 pm

    Absolutely loved this recipe. I have found a trick to making all cakes more moist is by adding 2 tablespoons of milk really helps make the sponges fluffier.

  4. Tracy Brown on June 28, 2023 at 6:01 pm

    Which size cookie scoop do you use as the link is for 3 sizes. xx

  5. Chanelle monks on May 10, 2023 at 11:33 am

    Turned out really lovely, just slightly dry? What have I done wrong?

    • Jane's Patisserie on April 24, 2023 at 9:45 am

      Hey! This just means they were over baked or baked at too high a temperature! x

  7. Caroline on January 8, 2023 at 8:34 pm

    Would this marshmallow frosting would be nice to cover an 8inch cake
    Thank you

    • Jane's Patisserie on January 10, 2023 at 3:02 pm

      Hiya! Depending on how many layers it is, it should be fine! x

  8. Gill Mitchell on December 21, 2022 at 6:21 pm

    Our frosting stayed quite soft.
    Just wondering what I may have done wrong?
    Could it have been from something as simple as putting the syrup in too quickly? Or not making the egg whites stiff enough at first?
    Any advise?

    • Jane's Patisserie on December 23, 2022 at 11:48 am

      Hiya! Yes it could be either, or not whisking the mixture for long enough! Hope this helps! x

  9. Elayne on December 21, 2022 at 2:04 pm

    Hi Jane….it’s my first time at making the marshmallow frosting – it doesn’t hold its shape and is very soft, loose… what did I do wrong and can I rectify it? Instructions followed to the letter, including the sugar temperature. Any help gratefully receive d!

    • Jane's Patisserie on December 23, 2022 at 11:46 am

      Hiya! This sounds like the egg whites or whole mixture wasn’t whisked for long enough! Hope this helps! x

  10. Jordan on December 20, 2022 at 5:37 pm

    • Jane's Patisserie on December 23, 2022 at 11:32 am

      Hiya! Yes, this should be fine! x

  12. Jasi on December 20, 2022 at 3:10 pm

    Can you make this using melted marshmallows or marshmallow fluff? If so please can you help ne with the instructions?
    The idea of making my own is a bit terrifying.

    • Jane's Patisserie on December 23, 2022 at 11:31 am

      Yes absolutely, take a look at the frosting recipe for my marshmallow cupcakes! Hope this helps! x

  13. Jordan on December 18, 2022 at 6:26 pm

    With this recipe where you mentioned to me about doing a butter cream do I make that and place that in the recipe to re place the marshmallows frosting and follow the rest of the recipe?
    Many thanks as I would like to have ago at making these

    • Jane's Patisserie on December 23, 2022 at 11:20 am

    Hi Jane! Love this recipe but I have loads of left over marshmallow icing, can I freeze It?

    • Jane's Patisserie on December 15, 2022 at 12:49 pm

      Yes, but it might need re whipping, and may have a slightly softer consistency after! Hope this helps! x

    Do these need to be kept in the fridge?

    • Jane's Patisserie on December 15, 2022 at 12:48 pm

      Hiya! No, they will be fine at room temp! Hope this helps! x

  18. Mel on December 13, 2022 at 1:19 pm

    These sound amazing! Do you think it would be possible to make them into baileys cupcakes but keeping the hot chocolate theme please? If so how much baileys would u recommend adding?

    • Jane's Patisserie on December 15, 2022 at 12:47 pm

      Try the sponge recipe from my baileys cupcake recipe! Hope this helps! x

  19. Jordan on December 12, 2022 at 7:12 pm

    Could you use double cream instead of meringue? I don’t like it.

    • Jane's Patisserie on December 15, 2022 at 12:42 pm

      You could absolutely use a whipped cream, though it may not last as long and will need to be kept int he fridge, or just a regular buttercream! Hope this helps! x

    • Jane's Patisserie on December 15, 2022 at 12:43 pm

      Hiya! They will last for about 3 days. Hope this helps! x

  22. Judith Davidson on December 12, 2022 at 11:49 am

    Could this be made as a traybake and please can you advise me?
    Also could you use a combination of Cadbury’s hot chocolate and cocoa as I have both in my cupboard?
    Thank you xx

    • Jane's Patisserie on December 15, 2022 at 1:51 pm

      Hiya! Sure, that should be fine! Enjoy! x

    thanks Jane ! love your recipes. I wanted to make your xmas tree brownies, could i use this recipe for the frosting with some green colouring ? would I need to add butter for firmness ?

    • Jane's Patisserie on December 15, 2022 at 1:50 pm

      Hiya! You can just colour the frosting yes! Though you have a fair amount left over, and it’s tough to make a small amount of this frosting! Hope this helps! x
