Right, I’ll be honest with you—white chocolate mousse and I didn’t get off to the best start. First time I made it, I overheated the chocolate, mixed everything too quickly, and ended up with a sweet, clumpy soup that I had to “serve” in coffee mugs with a smile that said, “yes, it’s meant to look like this.” It wasn’t.
But that was before I discovered this Mary Berry white chocolate mousse method—a proper keeper. It’s everything the first one wasn’t: creamy, light, and dangerously easy to polish off in one go. I’ve tweaked it just a bit over the years, but at its heart, it’s still Mary’s magic. You’ll get it done in 15 minutes flat, no baking, no faff.
Ingredients List
- 1/2 cup (120ml) whipping cream — for that airy, luscious texture
- 1/2 cup chopped white chocolate or white chocolate chips — choose something you’d eat plain
- 4 oz (115g) cream cheese — adds body and tang
- 1–3 tablespoons powdered sugar, divided — start with less, adjust as you go
- 1/2 teaspoon vanilla extract — rounds out the sweetness
- Pinch of salt — just trust me on this one
Optional garnish: fresh raspberries, white chocolate curls, or a mint sprig if you’re feeling fancy.
How To Make It (Instructions)
- Chill your mixing bowl and beaters in the fridge for 10 minutes if you can. It helps the cream whip better.
- In the chilled bowl, whip the cream until stiff peaks form. Don’t overbeat — it should stand up on its own, not turn to butter.
- In a separate bowl, melt the white chocolate gently—either in a double boiler or microwave in 30-second bursts at half power, stirring each time. It should be smooth and glossy, not scorched or gritty.
- Using the same beaters (no need to wash them—yay), beat the cream cheese with 1 tablespoon of powdered sugar until fluffy.
- Pour in the cooled, melted white chocolate, add the vanilla and salt, and beat again until smooth and creamy.
- Fold the whipped cream into the chocolate mixture gently using a spatula. If it’s being stubborn, you can use the mixer on the lowest setting, just until combined. Do not overmix.
- Taste. Add more powdered sugar if needed, and fold again. This step is important—sweetness levels vary depending on your chocolate.
- Spoon or pipe into ramekins, jars, or little glasses. If you want it firmer, refrigerate for 1–2 hours before serving.
I once forgot to taste before chilling—and served a beautifully bland mousse. Lesson: always have a spoon handy.

Common Mistakes
Why is my mousse grainy?
You probably overheated the white chocolate or didn’t let it cool slightly before adding it to the mix. Heat is a sneaky saboteur.
Why is the mousse runny?
The cream likely wasn’t whipped to stiff peaks or was overmixed when folding in. Chill everything beforehand and fold gently.
Can I use low-fat cream cheese?
You can, but I wouldn’t. It doesn’t whip the same and your mousse may end up a bit sad and limp. Go full-fat—it’s dessert, not salad.
Why does my mousse taste flat?
You might’ve skipped the salt. It seems small, but it wakes up the sweetness. I forgot it once and the whole thing tasted… beige.
Storage and Reheating Tips
- Fridge: Store mousse in airtight containers or covered ramekins. Keeps beautifully for up to 3 days.
- Freezer: Not recommended. It messes with the texture. It’s mousse, not ice cream.
- Reheating: Nope! This one’s a chill-only affair. Heat ruins the structure. Just serve it cold and proud.
What to Serve With It
- Fresh raspberries or strawberries — sharpness cuts through the richness.
- Dark chocolate shavings — contrast in flavour and colour.
- Espresso or black coffee — a bitter sip between bites makes each spoonful more indulgent.
I’ve also served this on top of a brownie once. Not for the faint-hearted.
FAQ Section
Can I make this gluten-free?
Yes, it’s naturally gluten-free. Just double-check your chocolate brand to avoid cross-contamination.
Can I make it ahead of time?
Absolutely. It holds up well in the fridge for a couple of days. Just garnish right before serving.
Can I add fruit purée to the mousse?
Yes, but go lightly—too much liquid can deflate the mousse. Swirl it in gently, or serve on the side.
Can I skip the cream cheese?
You can try mascarpone as a substitute, but without anything, it may lack body. The cream cheese gives it that lovely structure.
