Kids will love this deliciously sweet chocolate and marshmallow birthday cake. Watch it disappear within minutes of serving


For the birthday cake:

  • 125g (4 oz) good-quality dark chocolate, broken into pieces125g (4 oz) unsalted butter
  • 175g (6oz) caster sugar
  • 5 large eggs, separated
  • 55g (2oz) plain flour
  • 125g (4 oz) ground almonds

For the filling and icing:

  • 250ml (9fl oz) double cream
  • 55g (2oz) marshmallows
  • 250g (9oz) good-quality dark chocolate, chopped

For the marshmallow topping:

  • 300ml ( pt) double cream, whipped
  • 150g (5 oz) marshmallows

Try not to rush when you're cutting the sponge into four: the layers aren't thick and the birthday cake will be very moist because of the chocolate.


  1. Preheat the oven to 180C (350F, gas mark 4). Melt the chocolate pieces in a heatproof bowl set over a pan of simmering water.
  2. Using an electric mixer, cream the butter with 125g (4 oz) of the sugar until pale and light. Beat in the egg yolks one by one. Whisk the whites and the remaining sugar until stiff.
  3. Add the melted chocolate to the butter mix with the flour and almonds, and fold in gently. Fold in the egg whites, then spoon into a 20cm (8in) round cake tin (greased and base-lined with greaseproof paper) and cook for 30-40 mins or until the centre is just set. Leave to cool for 5 mins, then turn out on to a wire rack to cool completely.
  4. For the filling and icing, heat the cream and marshmallows until the cream is just boiling and the marshmallows have melted, stirring continuously. Pour over the chopped chocolate and mix gently until smooth, thick and glossy.
  5. Carefully cut the sponge horizontally into four. Spread three layers with some of the filling and sandwich together. Use the remaining mixture as an icing and spread on the top and sides of the cake. Chill until set.
  6. Spoon the whipped cream on top of the cake and decorate with a mound of marshmallows.

with following the recipe to the letter this cake turns out well but you might need to let it stay in oven longer

this cake is really good and im making for my gcse cooking final product


when i saw this cake i was so happy to make it really i was


Whoever has made this cake, how did you get it to rise? I've attempted to make this cake and it just didnt rise or anything. Its way too soft to cut and its very crumbley. I wanted if anyone had any solutions or some help?! Thanks

Ryan :)

this cake is soooo nice :) 10/10


i hate this recipe it didnt work and i only got half a cake! i made the marsmellow cake, i read the instructions several times and did what you told me to do.the half that i had looked all burnt and over cooked but when i tried it was all sticky and goey inside i put it in the oven for even longer but it still was sticky. i am very dissopointed with you and your website (none of yyour cakes are healthy) more regrets jade dixon :(


This cake is totally amazing!! I was sooo happy with it- made it for 15 people so did double quantities but it tastes like something bought from a bakery!! Only thing I would say is... careful when you make the filling that it doesn't curdle... if it does (which is what happened to me), pour off the watery bit then spread the rest as you would do normally, and it actually looks and tastes fine- like truffle!!


my cakes r yummy!!!!
