Print Recipe

The Mary Berry 9-Inch Sponge Cake is a British-style, all-in-one sponge that’s larger than the classic 8-inch version. Made with simple pantry ingredients—flour, butter, eggs, and sugar—it’s known for its airy crumb and golden crust. Ideal for layering or decorating, this sponge forms the base of many beloved Mary Berry desserts.

Ingredients

Scale

  • 350g self-raising flour

  • 350g unsalted butter (softened)

  • 350g caster sugar

  • 6 large eggs

  • 2 tsp baking powder

  • 3 tbsp milk

  • 1½ tsp vanilla extract

For filling and decoration:

  • 150g butter (softened)

  • 300g icing sugar

  • 2 tbsp milk

  • 1 tsp vanilla extract

  • Jam, fresh fruit, or whipped cream (optional)

Instructions

Step 1: Preheat the oven

Preheat your oven to 170°C (150°C fan). Grease and line two 9-inch round tins with baking parchment to prevent sticking.

Step 2: Combine ingredients

Add the butter, sugar, flour, eggs, baking powder, milk, and vanilla extract into a large mixing bowl. Beat together for 2–3 minutes until smooth, pale, and creamy. The batter should have a soft, drop consistency.

Step 3: Divide and level

Divide the mixture evenly between the two tins. Smooth the surface gently using a spatula for an even rise.

Step 4: Bake the sponges

Place the tins in the centre of the oven and bake for 35–40 minutes, or until the cakes are golden brown and springy to the touch. Insert a skewer—if it comes out clean, they’re ready.

Step 5: Cool completely

Let the cakes cool in the tins for 10 minutes before transferring them to a wire rack. Allow them to cool fully before filling.

Step 6: Prepare the filling

Beat the butter until creamy, then gradually add the icing sugar, milk, and vanilla. Whisk until smooth and fluffy.

Step 7: Assemble and decorate

Place one sponge on a cake stand, spread with buttercream and jam, then top with the second layer. Finish with a light dusting of icing sugar or frost with extra buttercream for a festive look.
