This rich, airy Mary Berry Chocolate Mousse is made with dark chocolate, fresh eggs, and lightly whipped cream, ready in just 20 minutes plus chilling. The magic happens when you gently fold the stiff egg whites into the chocolate mixture, creating a texture that is both decadent and cloud-like. I love serving this classic dessert in individual ramekins for an elegant finish to a dinner party.
Why This Classic Works
Mary Berry’s version of this dessert balances richness and lightness perfectly by using both separated eggs and whipped cream. Many mousse recipes rely solely on eggs, which can be intense, or too much cream, which dilutes the flavour, but this method hits the sweet spot between the two.
I used to rush the melting process and end up with grainy chocolate, but I learned that patience over gentle heat is the only way to get that glossy base. Taking the chocolate off the heat before adding the yolks is also crucial to prevent them from scrambling instantly.
Mary Berry Chocolate Mousse Ingredients
- 225g (8 oz) plain chocolate (39-50% cocoa solids), broken into pieces
- 30g (1 oz) unsalted butter (a generous knob)
- 1 tbsp brandy or rum (optional)
- 3 large eggs, separated
- 150ml (ΒΌ pint) double cream, lightly whipped
- Icing sugar, for dusting

How To Make Mary Berry Chocolate Mousse
- Melt the Chocolate: Place the broken chocolate pieces in a heatproof bowl set over a pan of simmering water, ensuring the bowl doesn’t touch the water. Melt slowly, then stir in the knob of butter until glossy.
- Add Yolks and Brandy: Remove the bowl from the heat and stir in the brandy (if using) and the egg yolks one at a time until the mixture is smooth and thickened. Set aside to cool slightly.
- Whip the Whites: In a separate grease-free bowl, whisk the egg whites until they are stiff but not dry.
- Combine and Chill: Lightly whip the double cream to soft peaks. Fold the cream into the chocolate mixture, then carefully fold in the egg whites in two batches until no white streaks remain. Spoon into ramekins or a large bowl and chill for at least 4 hours.

Recipe Tips
- Cool Before Mixing: Make sure the chocolate mixture has cooled slightly before adding the whipped cream, otherwise the cream will melt and lose its volume.
- The Fold Technique: Use a large metal spoon or spatula to cut through the middle and fold over the top; this preserves the air bubbles you worked so hard to whisk in.
- Chocolate Choice: Mary recommends plain chocolate with around 40-50% cocoa solids (like Bournville) rather than very dark 70% chocolate, which can make the mousse too bitter and heavy.
What To Serve With Chocolate Mousse
This rich dessert pairs beautifully with something crisp, like thin almond biscuits or langues de chat, to provide a texture contrast. Fresh raspberries or strawberries also work wonders, as their natural acidity cuts through the intense chocolate flavour.

How To Store
Keep the mousse covered in the fridge for up to 2 days; the flavour often deepens after the first 24 hours. Freezing is not recommended for this recipe as the egg-based structure tends to weep and separate when thawed.
FAQs
- Can I make this without alcohol? Yes, the brandy is optional; you can replace it with a teaspoon of vanilla extract or simply leave it out completely.
- Why is my mousse grainy? Graininess usually occurs if the chocolate was overheated or if water splashed into the melting bowl, causing it to seize.
- Is it safe to eat raw eggs? This classic recipe uses raw eggs; ensure you use fresh eggs with the British Lion mark (or pasteurised eggs) if serving to vulnerable groups.
