Marshmallow Cake

This is a simple cake to make and perfect for a celebration. I made two of these cakes last month, for a family and friend’s Birthday. It's a simple sponge cake filled with vanilla buttercream and mini marshmallows. Although it looks quite massive and perhaps filled with a little too much buttercream, the light sponge and the fact that the filling is mostly marshmallows results in a cake that isn’t at all heavy. A friend commented that it was like eating a cloud!

This cake is a definite hit with me and I’ve also used the marshmallow buttercream on cupcakes, finishing them off with a chunk of Cadbury Flake. If you’d like to do the same, the buttercream recipe below would be enough to decorate 12 cupcakes.

Marshmallow Cake

200g caster sugar
200g unsalted butter, softened
4 medium eggs
200g self raising flour
1 tsp baking powder
2 tbsp milk
1 tsp vanilla extract
120g unsalted butter, softened
375g icing sugar
25ml milk
2-3 drops vanilla extract
100g pink and white mini marshmallows

1. Preheat oven to 190°C (170°C fan). Line two 20cm round tins with baking paper and set aside.

2. Cream the butter and sugar until pale and light. In a separate bowl combine the eggs, milk and vanilla extract, and in another bowl combine the flour and baking powder.

3. Beat half of the wet ingredients into the creamed mixture, then mix through half of the flour.

4. Add the other half of wet ingredients and mix until combined. Finally stir in the remaining flour until you have a smooth and light batter.

5. Divide between the two lined tins and bake on the middle shelf of the oven for 20-25 minutes. Once cool enough to handle, carefully transfer to a cooling rack.

6. For the vanilla buttercream, beat the butter with half of the icing sugar until smooth. Then add the remaining icing sugar, milk and vanilla and beat once more until smooth and creamy.

7. Set aside about 4 tablespoons of icing – you’ll need this to decorate the top of the cake. Stir the marshmallows into the rest of the icing until fully incorporated.

8. Pop your one of your cakes onto a cake board (I used a silver one from the supermarket and added a doily from a pack I bought from Lakeland) or plate and pile on the marshmallow icing. Use a palette knife or the back of a spoon to spread it evenly and then place the other cake on top.

9. Pop the icing you put aside earlier into a piping bag fitted with a large star nozzle, and carefully pipe stars onto the top of the cake.

10. Now for the finishing touches. Dust with icing sugar, sprinkle with pink decorating sugar, add candles... Et Voila! A springy, light, marshmallowy cake. Enjoy :-)

    Although I'd have to find some Vegan marshmallows.
