Mary Berry Chocolate Fudge Cake Ingredients
For the Cake:
- 50g (2oz) sifted cocoa powder
- 6 tbsp. boiling water
- 3 large eggs
- 50ml (2fl oz) milk
- 175g (6oz) self-raising flour
- 1 rounded tsp. baking powder
- 100g (4oz) softened butter or baking spread
- 275g (10oz) caster sugar
For the Icing and Filling:
- 3 tbsp. apricot jam
- 150g (5oz) plain chocolate (around 40% cocoa solids)
- 150ml (¼ pint) double cream
How To Make Mary Berry’s Chocolate Fudge Cake
- Prep the oven and tins: Preheat the oven to 180°C/Fan 160°C/Gas 4. Grease two 20cm (8in) round sandwich tins and line the base of each with baking parchment.
- Make the cake batter: In a large bowl, blend the cocoa powder and boiling water to form a smooth paste. Add all the remaining cake ingredients (eggs, milk, flour, baking powder, butter, and sugar) to the bowl. Beat with an electric mixer or by hand until the mixture becomes a smooth, thick batter.
- Bake the cakes: Divide the cake batter equally between the two prepared tins and level the surfaces. Bake for 25-30 minutes, or until the cakes are well-risen and spring back when lightly pressed. Let them cool in the tins for a few minutes before turning them out onto a wire rack to cool completely.
- Prepare the icing and filling: Gently warm the apricot jam in a small pan. While the cakes are still warm, brush a little jam over the top of one cake (this will be the base) and the top of the other. To make the chocolate icing, break the chocolate into pieces and gently heat it with the double cream in a heatproof bowl set over a pan of simmering water, stirring until the chocolate has melted and the mixture is smooth.
- Assemble the cake: Let the chocolate icing cool until it is thick and spreadable. Spread a layer of the icing on top of the apricot jam on the base cake. Place the second cake layer on top. Use the remaining icing to cover the top and sides of the cake, smoothing it with a palette knife.

Recipe Tips
- How to get the perfect cake texture? This recipe uses Mary Berry’s famous “all-in-one” method. Adding all the cake ingredients to the bowl at once is simple and helps prevent the batter from curdling, resulting in a consistently moist cake.
- What is the purpose of the apricot jam? The thin layer of warmed apricot jam is a classic baker’s trick. It seals the sponge, preventing crumbs from getting into your chocolate icing and helping to lock in moisture.
- How to make a smooth ganache icing? The key is to melt the chocolate and cream together gently over low heat. Do not let the water in the pan touch the bottom of the bowl, as overheating can cause the chocolate to seize or the ganache to split.
- Can I use a different butter? Softened butter or a soft baking spread (like Stork) works perfectly. The key is that it should be soft but not oily to incorporate smoothly into the all-in-one batter.
What To Serve With Chocolate Fudge Cake
This rich cake is a wonderful treat on its own, but it’s also delicious with:
- A dollop of clotted cream or fresh whipped cream
- A scoop of vanilla bean ice cream
- A side of fresh raspberries or strawberries
How To Store Chocolate Fudge Cake
- Room Temperature: Store the cake in an airtight container in a cool place for up to 3-4 days.
- Freeze: The cake can be frozen, either iced or un-iced, for up to one month. Wrap it well in plastic wrap and then a layer of foil.

FAQs
Plain chocolate with around 40% cocoa solids is recommended for the right balance of flavor and sweetness. Using a much darker chocolate will result in a more bitter icing, while milk chocolate will be much sweeter.
The all-in-one method helps prevent this, but it can sometimes happen if your ingredients are too cold. Using room temperature eggs and softened butter is always a good practice.
Yes, but you will need to increase the baking time significantly (likely to 45-55 minutes) and check for doneness with a skewer. You would then need to slice the single cake in half horizontally once cooled.
