Anna Louise There are cakes you make for Tuesday afternoons, and there are cakes you make when something deserves to be genuinely celebrated. Mary Berry’s white chocolate and raspberry cake is firmly in the second category — and yet, wonderfully, it is not nearly as difficult to make as it looks.
This is one of the most beautiful cakes on this entire site. The sponge is light, tender, and fragrant — slightly enriched with white chocolate melted directly into the batter, giving it a subtle creaminess that you cannot quite put your finger on but absolutely notice.
Between the layers, a generous spread of white chocolate ganache and a scattering of fresh raspberries — their sharpness cutting through the sweetness of the white chocolate in exactly the right way. On top, more ganache, more raspberries, and perhaps a few white chocolate curls if you are feeling particularly celebratory.
It is the kind of cake that makes people gasp slightly when it arrives at the table. And when they taste it, that initial reaction is entirely justified.
If you have been searching for the perfect Mary Berry white chocolate and raspberry cake recipe, this is the one. Let me take you through every step.
Why White Chocolate and Raspberry Work So Beautifully Together
This is one of those flavour combinations that seems almost too obvious once you have tasted it — and yet somehow it never stops being wonderful.
White chocolate is rich, sweet, and deeply creamy, with that characteristic vanilla-like warmth. Fresh raspberries are sharp, bright, and intensely fruity. Together they create a balance that neither ingredient achieves alone — the white chocolate softens and enriches the raspberries’ acidity, and the raspberries cut through the white chocolate’s sweetness and stop it becoming cloying.
In cake form, this balance is particularly beautiful. The sharpness of the raspberries works its way into every bite, preventing the white chocolate elements from feeling heavy or overly sweet, and leaving you with a finished cake that is rich and indulgent but still somehow fresh and bright. It is a genuinely brilliant combination, and Mary Berry uses it to perfection.
Ingredients for Mary Berry White Chocolate and Raspberry Cake
Use the best quality white chocolate you can find — cheap white chocolate often contains very little actual cocoa butter and can taste waxy and artificial. A good quality white chocolate bar, chopped and melted, makes an enormous difference to the flavour of both the sponge and the ganache.

- Freeze-dried raspberry pieces (optional — adds a beautiful colour and concentrated flavour)
How to Make Mary Berry White Chocolate and Raspberry Cake — Step by Step
Step 1 — Melt the White Chocolate for the Sponge
Break the white chocolate for the sponge into pieces and place in a heatproof bowl set over a pan of barely simmering water. Make sure the bottom of the bowl does not touch the water — white chocolate is more sensitive to heat than dark chocolate and can seize if it gets too hot.
Stir gently until just melted, then remove from the heat immediately and set aside to cool to room temperature. Give it at least ten minutes — you do not want warm chocolate going into your batter.
Step 2 — Preheat and Prepare
Preheat your oven to 180°C / 160°C fan / Gas 4. Grease two 20cm round sandwich tins and line the bases and sides with baking parchment.
Step 3 — Cream the Butter and Sugar
Beat the softened butter and caster sugar together with an electric hand whisk for four to five minutes until very pale, light, and fluffy. This step is particularly important in this recipe — the white chocolate in the batter adds richness and density, and properly creamed butter and sugar introduces the air needed to keep the sponge light.
Step 4 — Add the Eggs and Vanilla
Add the eggs one at a time, beating well after each addition. Add the vanilla extract with the final egg. If the mixture looks like it might curdle at any point, add a tablespoon of the sifted flour and beat it in before continuing.
Step 5 — Add the Melted White Chocolate
Pour the cooled melted white chocolate into the bowl. Fold through gently with a spatula until fully incorporated. The batter will take on a beautifully rich, creamy appearance.
Step 6 — Fold in the Flour
Sift the self-raising flour, baking powder, and salt into the bowl. Add the milk. Fold gently until just combined — the batter should be smooth, pale, and quite thick. Do not overmix.
Step 7 — Bake
Divide the batter equally between the two prepared tins — weigh them on the scales for perfectly even layers. Smooth the tops and bake on the middle shelf for 25 to 30 minutes until the sponges are golden, well risen, and a skewer inserted into the centre comes out clean.
Leave to cool in the tins for 10 minutes, then turn out onto a wire rack to cool completely. The sponges must be completely cold before you apply the ganache — white chocolate ganache melts very easily.
Step 8 — Make the White Chocolate Ganache
Place the finely chopped white chocolate in a large heatproof bowl. Heat the double cream in a small saucepan over a medium heat until it just begins to simmer — small bubbles appearing around the edges. Do not let it boil.
Pour the hot cream over the chopped white chocolate. Add the vanilla extract. Leave to stand for two minutes without stirring, then stir gently from the centre outwards in slow, steady circles until completely smooth and glossy. Add the butter and stir until melted and incorporated.
Leave the ganache to cool at room temperature, stirring occasionally, until it thickens to a spreadable consistency. This will take 45 minutes to an hour — white chocolate ganache takes longer to set than dark chocolate ganache. Do not refrigerate to speed this up as it can set unevenly. Be patient — it is worth the wait.
Step 9 — Assemble the Cake
Place one completely cooled sponge on your serving plate or cake stand. If using, brush a thin layer of warmed, sieved raspberry jam over the surface — this adds an extra layer of raspberry intensity and helps the raspberries adhere.
Spread a generous layer of white chocolate ganache over the surface. Arrange half the fresh raspberries over the ganache in an even layer, pressing them down very gently.
Place the second sponge on top, pressing down gently. Spread the remaining ganache over the top and down the sides of the cake — use a palette knife for a smooth finish, or create relaxed swirls for a more informal look.
Step 10 — Decorate
Arrange the remaining fresh raspberries over the top of the cake. Add white chocolate curls or shavings, a dusting of icing sugar, and a few mint leaves if using. Scatter freeze-dried raspberry pieces over the top for extra colour and a concentrated burst of raspberry flavour.
Leave the ganache to set at room temperature for at least 30 minutes before slicing.
My Top Tips for the Perfect White Chocolate and Raspberry Cake
Use the best white chocolate you can afford. This is the most important ingredient decision in this recipe and I cannot stress it enough. Cheap white chocolate — the kind that lists vegetable fat rather than cocoa butter as the main fat — tastes waxy, artificial, and overwhelmingly sweet. Good white chocolate — Lindt, Green and Black’s, or a good supermarket own-brand baking chocolate — tastes creamy, vanilla-rich, and genuinely wonderful. The difference in the finished cake is dramatic.
Be very careful not to overheat white chocolate when melting it. White chocolate has a lower melting point than dark chocolate and seizes — turns grainy and stiff — very easily if it gets too hot. Use a bowl set over barely simmering water, stir gently and constantly, and remove from the heat the moment it is melted. If it seizes, add a tablespoon of warm cream and stir gently — this can sometimes rescue it.
Make sure everything is completely cool before assembling. White chocolate ganache is much softer at room temperature than dark chocolate ganache. Even slightly warm sponges or ganache that has not fully cooled and set will make assembly very difficult. Patience here pays off enormously.
Use fresh raspberries, not frozen. Frozen raspberries release a lot of liquid as they thaw and will make the ganache and the sponge soggy. Fresh raspberries hold their shape, look beautiful, and give you that clean, bright flavour. If fresh raspberries are out of season and expensive, a good quality raspberry preserve between the layers works well as a substitute — just skip the fresh raspberries in the filling and use them only for decoration on top.
Refrigerate the assembled cake before slicing. Unlike most cakes, which are best at room temperature, this one actually benefits from 20 to 30 minutes in the fridge after assembly before the first slice is cut. The ganache firms up just enough to give you clean, neat slices that hold their shape beautifully. Just remember to bring it back to room temperature before serving — about 20 minutes on the counter.
Add freeze-dried raspberries to the decoration. This is an optional step but one I never skip. Freeze-dried raspberries add an intense, concentrated raspberry flavour, a beautiful deep pink colour, and a lovely slight crunch to the finished decoration. They look stunning and taste wonderful. Most supermarkets stock them in the baking aisle.
Serving Suggestions
This is a celebration cake in every sense. It is wonderful at birthdays, at summer garden parties, at wedding celebrations, and at any occasion where you want something that looks genuinely spectacular and tastes even better.
Serve at room temperature with a small spoonful of lightly whipped cream on the side. A glass of Prosecco alongside is rather wonderful. For a more casual afternoon tea, serve in thick slices with a pot of good English Breakfast tea — the sharpness of the tea balances the richness of the white chocolate beautifully.
How to Store Mary Berry White Chocolate and Raspberry Cake
In the fridge: Because of the fresh raspberries and white chocolate ganache, this cake must be stored in the fridge. Keep in an airtight container for up to 3 days. Always bring to room temperature for at least 20 to 30 minutes before serving.
At room temperature: Fine for up to 2 hours in a cool kitchen. The fresh raspberries mean it should not be left out for longer than this.
In the freezer: Freeze the unfrosted sponge layers for up to 3 months, wrapped tightly in cling film and foil. Make the ganache fresh and use fresh raspberries when ready to assemble. Do not freeze the assembled cake.

Notes
Frequently Asked Questions About Mary Berry White Chocolate and Raspberry Cake
Can I use frozen raspberries instead of fresh?
For the filling only — not for decoration. Frozen raspberries release a lot of liquid as they thaw, which can make the ganache and sponge soggy if used generously. If you do use them in the filling, fold them in straight from frozen and use sparingly. For decoration, always use fresh.
My white chocolate ganache is too runny — how do I fix it?
White chocolate ganache needs more time to set than dark chocolate ganache — give it more time at room temperature, stirring occasionally. If after an hour it is still very loose, pop it in the fridge for 10 to 15 minutes, then stir again. If it is still too loose, you can add a small amount of extra melted white chocolate to thicken it — melt 50g extra white chocolate, let it cool slightly, and stir it into the ganache.
Can I use raspberry coulis instead of fresh raspberries in the filling?
Yes — a thick raspberry coulis spread between the layers with the ganache is absolutely delicious and gives a more evenly distributed raspberry flavour. Make sure it is quite thick so it does not make the ganache too wet. A thin layer alongside the ganache rather than instead of it works best.
Can I make this cake as a three-layer cake?
Absolutely — make one and a half times the sponge recipe and divide between three 20cm tins, reducing the bake time slightly. Make one and a half times the ganache. Three layers look spectacular and give you a truly showstopping celebration cake.
Can I add lemon to the white chocolate and raspberry cake?
Yes — lemon and white chocolate and raspberry is a genuinely beautiful combination. Add the zest of one unwaxed lemon to the sponge batter and the zest of half a lemon to the ganache. The citrus brightens the whole cake and adds another dimension to the flavour.
Why did my white chocolate seize when I melted it?
White chocolate seizes when it comes into contact with even a tiny amount of water, or when it overheats. Make sure your bowl, spatula, and everything that touches the chocolate is completely dry before you start. Melt over barely simmering water — not boiling — and remove from the heat as soon as it is melted.
