How to Make Mary Berry Chocolate Fudge 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 cake batter: Place the flour, baking powder, cocoa powder, caster sugar, butter, eggs, and milk into a large mixing bowl. Beat until the mixture becomes smooth and evenly combined.
- Fill the tins: Divide the batter evenly between the prepared tins and level the surfaces with a spatula.
- Bake the cakes: Place the tins in the center of the oven and bake for 30 to 35 minutes until risen and springy to the touch.
- Cool completely: Leave the cakes in their tins for 10 minutes, then transfer to a wire rack and allow them to cool fully.
- Make the frosting: Melt the chocolate and butter together in a heatproof bowl. Stir until smooth, then mix in the icing sugar, milk, and vanilla extract until thick and glossy.
- Assemble the cake: Spread one-third of the frosting over one sponge layer. Place the second sponge on top and cover the top and sides with the remaining frosting.
- Decorate and serve: Finish with chocolate curls or grated chocolate and serve once the frosting has set slightly.

Why is my frosting too thick?
Add a small amount of milk, one teaspoon at a time, until the desired consistency is reached.
Can I use milk chocolate instead of dark chocolate?
Yes, but the frosting will be sweeter and have a milder chocolate flavor.
How do I get even cake layers?
Use a kitchen scale to divide the batter equally between the tins before baking.
