Mary Berry’s Raspberry and White Chocolate Cake is a rich, moist sponge cake made with white chocolate chunks and fresh raspberries folded into the batter. The cake has a soft texture and a subtle vanilla flavor, perfectly complemented by the sweetness of white chocolate and the tartness of raspberries. This cake can be served on its own or topped with a creamy white chocolate frosting for added decadence.
Preheat your oven to 180°C (160°C fan) or 350°F. Grease and line two 8-inch round cake tins with parchment paper.
In a mixing bowl, beat the softened butter and caster sugar together with an electric mixer until light and fluffy. This takes about 3-4 minutes.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract until combined.
Sift the self-raising flour and baking powder over the mixture and fold gently until just combined.
Gently fold in the chopped white chocolate and fresh raspberries, being careful not to overmix or crush the berries.
Divide the batter evenly between the prepared cake tins, smoothing the tops with a spatula. Bake in the preheated oven for 25-30 minutes, or until a skewer inserted into the center comes out clean.
Allow the cakes to cool in their tins for 10 minutes, then transfer them to a wire rack to cool completely before frosting.
For the frosting, beat the softened butter and sifted icing sugar together until creamy and smooth. Stir in the melted white chocolate and add milk as needed to reach a spreadable consistency.
Spread a layer of frosting on top of one cake layer, place the second layer on top, and spread frosting over the top. Garnish with extra raspberries or white chocolate shavings if desired.
