Mousse al Cioccolato Fondente (Dark Chocolate Mousse)
Why this recipe works
- Light but creamy: Whipped cream adds richness, while folded meringue keeps the mousse airy rather than dense.
- Deep chocolate flavour: Dark chocolate, butter, vanilla and a little salt create a clean cocoa profile with rounded richness.
- Ideal for preparing ahead: The mousse needs chilling to set, so it can be made in advance and served straight from the fridge.

Timing notes
- Allow enough chilling time: Chill the mousse for at least 2 hours so the structure sets and the texture becomes airy and spoonable.
- Serve well chilled: The mousse is best served cold from the fridge; it will soften if left at room temperature for too long.
- Best within two days: It keeps covered in the fridge for up to 2 days, though the volume is at its best earlier.
Ingredient notes
- Choose good dark chocolate: A 70% cocoa baking chocolate gives the mousse its intense flavour and helps it set with a clean finish.
- Use pasteurised eggs if needed: Because the eggs are not cooked through, pasteurised eggs are the safer choice for pregnant people, young children, older adults or anyone immunocompromised.
- Cocoa percentage matters: Higher-cocoa chocolate gives a firmer, more intense mousse, while lower-cocoa chocolate will taste sweeter and set a little softer.
Texture tips
- Fold gently: Use broad, light folding motions and stop as soon as no white streaks remain to preserve the air in the cream and meringue.
- Cool the chocolate slightly: Let the melted chocolate cool until just warm before combining, so it blends smoothly without tightening or turning grainy.
- Whip cream only to soft peaks: Softly whipped cream folds in more easily and gives a smoother mousse than stiffly whipped cream.

Ingredients
Instructions
- Set out 4 small glasses. Separate the eggs, putting the whites in a clean mixing bowl and the yolks in a second bowl.
- Melt the dark chocolate with the butter in a heatproof bowl set over a saucepan of barely simmering water, stirring until smooth. Take off the heat and leave to cool until just warm to the touch.
- Whisk the egg yolks with half the caster sugar until paler and slightly thickened, then whisk in the vanilla extract and fine sea salt. Whisk in the warm melted chocolate until glossy and fully combined.
- In a separate bowl, whip the double cream to soft peaks, so it holds its shape but still looks billowy. Fold the whipped cream into the chocolate mixture in two additions until almost combined.
- Whisk the egg whites to soft peaks, then gradually whisk in the remaining caster sugar until you have a glossy meringue that holds medium peaks. Fold one third into the chocolate mixture to loosen it, then gently fold in the rest until no white streaks remain.
- Divide the mousse between the glasses and level the tops. Chill for at least 2 hours, or until airy and spoonable.
Recipe notes
Tips
- For the lightest texture, make sure the bowl for the egg whites is completely grease-free, and fold with a light hand to keep as much air as possible.
- If serving to pregnant people, young children, older adults, or anyone immunocompromised, use pasteurised eggs as the mousse is not cooked.
Substitutions
- Replace Vanilla extract with vanilla bean paste for a more pronounced vanilla flavour.
- Replace Caster sugar with granulated sugar, whisking for an extra minute or two so it dissolves fully in the egg whites.
Storage
- Refrigerate up to 2 days
- Keep covered in the fridge and serve well chilled. The mousse will soften and lose some volume if held longer than 2 days.
