Mary Berry White Chocolate and Raspberry Cake Recipe

Some flavour combinations just make sense, and white chocolate with raspberry is one of those pairings that works every single time without fail. Mary Berry’s version takes that combination and turns it into a proper showstopper layer cake. Mary Berry’s white chocolate and raspberry cake is a light, moist vanilla sponge enriched with melted white chocolate, layered with raspberry jam and white chocolate buttercream, and finished with fresh raspberries on top elegant, balanced, and genuinely one of the most crowd-pleasing bakes I’ve ever put on a table.

Why This Flavour Pairing Works So Well

White chocolate brings sweetness and a creamy, almost vanilla-like richness to the sponge. Raspberries bring sharpness and a bright acidity that cuts right through all that richness. Together, they balance each other out in a way that neither ingredient achieves alone. The raspberries stop the cake from tasting cloying, and the white chocolate stops the fruit from making things too tart.

Mary Berry understands this balance instinctively. She doesn’t overload the sponge with white chocolate she uses just enough to enrich the crumb without making it heavy. The raspberries do the rest. It’s a cake that tastes as good as it looks, which in my experience isn’t always guaranteed with pretty layer cakes.

Ingredients You’ll Need

A slightly longer list than a basic Victoria sponge, but every item earns its place. Quality white chocolate makes a noticeable difference here use a bar, not chips.

For the white chocolate sponge

• 200g unsalted butter, softened
• 200g caster sugar
• 4 large eggs, at room temperature
• 200g self-raising flour, sifted
• 1 tsp baking powder
• 100g good-quality white chocolate, melted and cooled
• 2 tbsp milk
• 1 tsp vanilla extract

For the white chocolate buttercream

• 175g unsalted butter, softened
• 350g icing sugar, sifted
• 100g white chocolate, melted and cooled
• 2–3 tbsp double cream

For the filling and topping

• 4 tbsp raspberry jam, seedless, gives a cleaner finish
• 150g fresh raspberries
• White chocolate shavings to decorate (optional but worth it)

FYI, melt your white chocolate slowly over a bain-marie rather than the microwave. White chocolate burns and seizes far more easily than dark, and a seized batch of white chocolate is a genuinely miserable thing to deal with mid-recipe.

How to Make It Step by Step

Step 1: Make the sponge

Preheat your oven to 180°C (160°C fan). Grease and line two 20cm sandwich tins. Beat the softened butter and caster sugar together for 4–5 minutes until pale and fluffy Don’t rush this, it builds the structure of the sponge. Add the eggs one at a time, beating well after each. Fold in the sifted flour and baking powder, then stir in the cooled melted white chocolate, milk, and vanilla until just combined.

Step 2: Bake and cool

Divide the batter evenly between the two tins and bake for 22–25 minutes until risen, golden, and a skewer inserted in the centre comes out clean. Cool in the tins for 10 minutes, then turn out onto a wire rack and cool completely. Completely means completely, even a slightly warm sponge will melt your buttercream on contact and the whole thing slides apart.

Step 3: Make the white chocolate buttercream

Beat the softened butter on high speed for 3–4 minutes until pale and creamy. Add the sifted icing sugar gradually, alternating with the cooled melted white chocolate and double cream. Beat until smooth, glossy, and spreadable. The finished buttercream should hold its shape but spread easily Add cream by the teaspoon to loosen if needed. Taste it. IMO, this buttercream alone is reason enough to make this cake.

Step 4: Assemble with confidence

Place one sponge layer on your serving plate or cake board. Spread the raspberry jam generously across the surface, then add a layer of white chocolate buttercream on top of the jam. Place the second sponge layer on top and press down gently. Frost the top with the remaining buttercream and arrange fresh raspberries across the surface in whatever pattern makes you happy. Scatter white chocolate shavings for the finishing touch.

Tips for Getting It Right

• Cool the melted chocolate to room temperature before adding to the batter or buttercream Hot chocolate scrambles the eggs in the batter and melts the butter in the frosting
• Use a kitchen scale rather than cups.This is a British recipe and the ratios are built around weight measurements
• Seedless raspberry jam gives a cleaner look and a smoother filling seeds can make the layers slide slightly
• Add the fresh raspberries to the top no more than 2 hours before serving they release juice over time and can stain the buttercream pink
• Refrigerate the assembled cake for 20 minutes before slicing for cleaner, neater cuts

Common Questions

Can I use frozen raspberries instead of fresh?

For the topping, stick with fresh frozen raspberries release too much water as they thaw and turn the buttercream surface wet and messy. For the jam filling, frozen raspberries work perfectly fine if you cook them down into a quick compote instead of using shop-bought jam.

How do I stop my white chocolate from seizing when melting?

Use a heatproof bowl over barely simmering water the bowl should not touch the water. Stir constantly and remove from heat the moment the chocolate is mostly melted, then stir off the heat until smooth. Even one drop of water can cause white chocolate to seize, so make sure your bowl and spatula are completely dry before starting.

How long does this cake keep?

It keeps well for 2–3 days in an airtight container in the fridge. Bring it to room temperature for at least 30 minutes before serving cold buttercream loses its creamy texture and the sponge feels denser than it should. The flavours actually develop nicely overnight, making day-two slices arguably better than day-one.

Final Thought

Mary Berry’s white chocolate and raspberry cake is the kind of bake that looks like it required far more skill than it actually did and that’s exactly what makes it so satisfying to make. Two simple sponge layers, a generous white chocolate buttercream, sharp raspberry jam, and fresh fruit on top. The combination does all the work for you.

Bake it for a birthday, an afternoon tea, or any occasion that deserves something a little special. Once you land it, it becomes your signature cake and people will ask you to make it every time. Consider yourself warned.
