How to Make Mary Berry Gluten-Free Chocolate Cake Recipe
- Prepare the oven: Preheat the oven to 180°C or 160°C fan. Grease and line two 20cm round cake tins with baking parchment.
- Mix the dry ingredients: Place the gluten-free flour, cocoa powder, caster sugar, and baking powder into a large mixing bowl and stir together.
- Add the wet ingredients: Add the softened butter, eggs, and milk. Beat using an electric mixer until smooth and fully combined.
- Fill the tins: Divide the mixture evenly between the prepared tins and level the tops with a spatula.
- Bake the cakes: Bake for 30 to 35 minutes until the cakes are risen and spring back when lightly pressed in the center.
- Cool completely: Leave the cakes in the tins for 10 minutes, then transfer to a wire rack to cool completely.
- Make the frosting: Beat the butter until creamy. Add the icing sugar, cocoa powder, and melted chocolate, then mix until smooth and fluffy.
- Assemble the cake: Spread frosting over one cake layer, place the second layer on top, then cover the top with the remaining frosting.
- Decorate and serve: Finish with chocolate shavings and serve once the frosting has set slightly.
