Step-by-Step Guide to Making Mary Berry Chocolate Sponge Cake

• Prepare the oven and tins – Preheat the oven to 180°C (350°F) and grease two 8-inch cake tins. Line the bases with baking parchment.
• Mix dry ingredients – Sift together self-raising flour, cocoa powder, and baking powder into a bowl.
• Cream butter and sugar – Beat the butter and caster sugar until pale and fluffy.
• Add eggs gradually – Mix in the eggs one at a time, beating well after each addition.
• Add vanilla and milk – Stir in the vanilla extract and milk.
• Combine dry ingredients – Gently fold the flour mixture into the batter using a spatula.
• Divide the batter – Pour the mixture evenly between the prepared cake tins.
• Bake the cakes – Bake for 20–25 minutes, until the sponge springs back when lightly pressed.
• Cool completely – Allow the cakes to cool on a rack before assembling.
• Prepare the buttercream – Beat butter and icing sugar until smooth, then add cocoa powder and milk.
• Assemble the cake – Spread buttercream over one sponge layer, place the second layer on top, and frost the top evenly.

What I Got Wrong (And How I Fixed It)

• Overmixing the batter – This made the sponge dense; folding gently fixed it.
• Cold butter during mixing – Softened butter creamed more smoothly.
• Uneven cake layers – Leveling the sponge helped create a neat cake.
• Adding frosting to warm cake – Letting the cake cool prevented melting.

Healthier Version of Mary Berry’s Chocolate Sponge Cake

You can make a lighter version by replacing half of the butter with Greek yogurt, which keeps the cake moist while reducing fat.

Using 70% dark cocoa powder or dark chocolate can also lower sweetness while deepening the chocolate flavor.

Reducing the buttercream slightly and serving with fresh berries is another simple way to lighten the dessert.
