Mary Berry Marble Cake
Print Recipe

Mary Berry’s Marble Cake is a moist sponge made from a basic butter cake batter divided into two portions—one flavoured with cocoa and one left plain. The two batters are alternately spooned into a tin and gently swirled to create a marbled pattern. Once baked, it can be finished with a dusting of icing sugar or a smooth chocolate glaze.

Ingredients

Scale

  • 225g self-raising flour

  • 225g unsalted butter (softened)

  • 225g caster sugar

  • 4 large eggs

  • 2 tbsp milk

  • 2 tbsp cocoa powder

  • ½ tsp baking powder

  • 1 tsp vanilla extract

Optional glaze:

  • 100g dark chocolate

  • 2 tbsp double cream

  • 1 tsp butter

Instructions

Step 1: Prepare the oven and tin

Preheat the oven to 180°C (160°C fan). Grease a 20cm cake tin and line the base with baking paper.

Step 2: Cream butter and sugar

In a large bowl, beat the softened butter and caster sugar together until pale and fluffy. This step ensures a light and airy sponge.

Step 3: Add eggs and vanilla

Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.

Step 4: Fold in the flour

Sift in the self-raising flour and baking powder. Gently fold with a spatula, adding a splash of milk if the batter feels too thick.

Step 5: Divide and flavour the batter

Split the batter evenly into two bowls. In one bowl, mix in the sifted cocoa powder and an extra tablespoon of milk to loosen the texture.

Step 6: Create the marble effect

Spoon alternating dollops of vanilla and chocolate batter into the prepared tin. Once all the mixture is used, swirl lightly with a skewer or knife to create the marbled pattern. Don’t overmix or the colours will blend too much.

Step 7: Bake the cake

Bake in the preheated oven for 40–45 minutes, or until a skewer inserted into the centre comes out clean. Let the cake cool in the tin for 10 minutes, then transfer it to a wire rack to cool completely.

Step 8: Add the glaze (optional)

Melt the chocolate, cream, and butter together over low heat until smooth. Pour over the cooled cake and spread evenly for a glossy finish.
