Marshmallow topped chocolate cupcakes (vegetarian)

Marshmallow fluff. It has been sat in my cupboard for too long. I just couldn’t think what to do with it… Until now!

Marshmallow fluff

Sumptuous chocolate cupcakes topped with dreamy marshmallow icing. Get involved!

Marshmallow topped cupcakes


  • 60g butter (at room temperature)
  • 150g sugar
  • 1 egg
  • 20g cocoa powder
  • 150g plain flour
  • 140ml buttermilk
  • 1/2 tsp bicarbonate of soda
  • 1 1/2tsp white wine vinegar


  1. Make buttermilk. Bring normal milk to the boil. Once it has cooled, add a teaspoon or so of lemon juice or white wine vinegar (whichever is on hand). Give it a mix ā€“ and voila ā€“ you have buttermilk!
  2. Preheat your oven to about 170C, and prepare your tin by lining it with cupcake cases.
  3. Mix the butter and sugar until it is light and fluffy.
  4. Mix in the egg.
  5. Mix in the cocoa powder.
  6. Add the flour and buttermilk, and lightly mix it round a couple of times.
  7. Add the bicarbonate of soda and vinegar, and fold the mix until everything is combined. Try not to mix it too much, else your cakes might not be soft.
  8. Spoon the mixture evenly between the cupcake cases, and bake them for about 25 minutes.
  9. Remove the baked cupcakes from the oven, and put them on a wire rack. Leave to cool completely.

  1. Throw the icing on the cake (and in your mouth), in any fashion you prefer!
