Ingredients
For the Malted Chocolate Sponge
- 225g unsalted butter, softened
- 225g caster sugar
- 4 large eggs
- 200g self-raising flour
- 25g cocoa powder
- 2 tbsp malted milk powder
- 1 tsp baking powder
- 2 tbsp milk
For the Chocolate Malt Buttercream
- 150g unsalted butter, softened

How to Make Mary Berry Malted Chocolate Cake
- Prepare the Oven and Tins: Preheat the oven to 180°C (160°C fan). Grease and line two 20cm round cake tins with baking parchment, ensuring the bases are well covered.
- Mix the Cake Batter: Place the butter, caster sugar, eggs, self-raising flour, cocoa powder, malted milk powder, baking powder, and milk into a large mixing bowl. Beat with an electric mixer for about 2 minutes until the mixture is smooth, pale, and well combined.
- Bake the Cakes: Divide the mixture evenly between the prepared tins and level the tops with a palette knife. Bake for 25 minutes, or until the cakes are well risen, spring back when lightly pressed, and a skewer inserted into the centre comes out clean.
- Cool Completely: Leave the cakes to cool in their tins for 5 minutes, then turn out onto a wire rack. Peel away the parchment and allow the sponges to cool completely before icing.
- Make the Buttercream: Beat the butter until very soft and creamy. Gradually add the icing sugar, malted milk powder, cocoa powder, and enough milk to create a smooth, spreadable buttercream with a light, fluffy texture.
- Assemble the Cake: Place one sponge on a serving plate and spread evenly with half of the buttercream. Top with the second sponge and use the remaining buttercream to cover the top. Finish with a light dusting of cocoa powder or grated chocolate.

Tips for Best Results
Why does my cake feel dry?
Overbaking is the most common cause. Check the cakes a few minutes before the suggested time and remove them as soon as they are just cooked through.
How do I get a stronger malt flavour?
You can increase the malted milk powder by 1 tablespoon in both the sponge and the buttercream without affecting the texture.
Can I make this cake without an electric mixer?
Yes, but be sure the butter is very soft and beat thoroughly with a wooden spoon to incorporate enough air.
Serving Suggestions
- Serve with a cup of tea or coffee for a classic afternoon treat
- Add fresh berries on the side for a lighter finish
