Mary Berry 10-Inch Sponge Cake

Mary Berry 10-Inch Sponge Cake

Mary Berry’s 10-Inch Sponge Cake is a classic British-style sponge made using her signature all-in-one method. It’s a larger version of her standard 8-inch cake, using scaled-up quantities to ensure the same light and even rise. This sponge forms an excellent base for birthdays, weddings, or afternoon teas.

Ingredients

Scale
  • 400g self-raising flour

  • 400g unsalted butter (softened)

  • 400g caster sugar

  • 7 large eggs

  • 2 tsp baking powder

  • 4 tbsp milk

  • 2 tsp vanilla extract

For filling and topping (optional):

  • 200g butter (softened)

  • 400g icing sugar

  • 2 tbsp milk

  • 1 tsp vanilla extract

  • Jam, fresh fruit, or whipped cream for layering

Instructions

Step 1: Preheat and prepare tins

Preheat your oven to 170°C (150°C fan). Grease and line two 10-inch round tins with baking parchment. Ensure the sides are well-greased to help the cakes rise evenly.

Step 2: Combine ingredients

In a large bowl, add the self-raising flour, butter, caster sugar, eggs, baking powder, milk, and vanilla extract. Beat all ingredients together using an electric mixer for 2–3 minutes until the mixture is smooth and light.

Step 3: Divide and level the batter

Divide the mixture evenly between the two tins. Smooth the tops gently with a spatula to create an even surface for baking.

Step 4: Bake the sponge

Bake for 40–45 minutes, or until the cakes are golden and spring back when lightly pressed. A skewer inserted in the centre should come out clean.

Step 5: Cool completely

Leave the cakes in their tins for 10 minutes before turning out onto a wire rack to cool fully. This prevents breakage and helps the crumb set properly.

Step 6: Prepare the buttercream filling

In a clean bowl, beat the softened butter until creamy. Gradually add icing sugar, then mix in milk and vanilla extract until smooth and spreadable.

Step 7: Assemble the cake

Place one sponge on a serving plate, spread with jam and a layer of buttercream. Top with the second sponge and dust with icing sugar or cover with more buttercream if decorating for a special occasion.
