Gluten-free chocolate O’s cake

Servings: 8 | Preparation time: 10 minutes | Cooking time: 30 minutes


For the sponge:

  • 400g Schär Mix It! Universal
  • 90g cocoa powder
  • 6tsp gluten free baking powder
  • 300g butter at room temperature
  • 330g caster sugar
  • 6 large eggs, beaten
  • 4½ tbsp milk
  • 2½ tsp vanilla extra

For the filling:

  • 500g butter at room temperature
  • 1.2kg icing sugar
  • 1 tsp vanilla extract
  • 4 tbsp milk
  • 150g dark chocolate
  • 75g cocoa powder

For the decorations:


  1. Pre-heat the oven to 170°/150°C Fan/Gas Mark 3.
  2. Place the butter and caster sugar into a mixing bowl and beat well for 1-2 minutes using an electric mixer, until the mixture is light and pale.
  3. Add the remaining sponge ingredients and mix for a further 2 minutes.
  4. Place into two round 20cm cake tins that have been greased and base-lined with baking parchment.
  5. Bake in the pre-heated oven for 30 minutes, or until the cakes spring back when lightly touched.
  6. Leave in the tins for 10 minutes before turning out onto a cooling rack.
  7. To make the buttercream and decorate: Beat together the butter, icing sugar, vanilla extract and milk until soft. Place 2 generous tablespoons of mixture in one bowl and 4 into another (the smaller amount for the cake topping and the rest for the cake filling).
  8. Crumble 4 Chocolate O’s into the buttercream, to make the filling. Spread evenly between the sponge layers.
  9. Melt the chocolate in a small bowl over a pan of hot water or carefully melt in a microwave.
  10. Pour the chocolate into the remaining buttercream and mix well. Add more milk if necessary to achieve a soft consistency. Spread this over the top and sides of the cake.
  11. Decorate the top of the cake with your choice of Schär biscuits.
  12. 16-17 Chocolate O’s are required to decorate the base of the cake.
