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.
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
200g butter (softened)
400g icing sugar
2 tbsp milk
1 tsp vanilla extract
Jam, fresh fruit, or whipped cream for layering
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.
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.
Divide the mixture evenly between the two tins. Smooth the tops gently with a spatula to create an even surface for baking.
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.
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.
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.
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.
