There’s something timeless about a simple chocolate mousse. It feels both effortless and indulgent, the kind of dessert that always impresses without requiring hours in the kitchen. I’ve made this recipe for dinner parties and family gatherings, and it never disappoints. The light, airy texture of the mousse with the crunch of salted hazelnuts on top is a combination that feels classic but still special.
Another thing I love about this dessert is that it’s make-ahead friendly — you can prepare it earlier in the day and pull it out of the fridge when you’re ready to serve. I’ve even made it in a rush before with only the minimum 4 hours of chilling time, and it was still delicious, but if you can leave it overnight the flavour and texture really do become even better. If you love a dessert that sets ahead of time, my Rose and Raspberry Panna Cotta and Burnt Basque Cheesecake are two more favourites that I often prepare the day before serving.
Why You’ll Love This Recipe
- Make ahead – the mousse sets in the fridge, freeing you up to enjoy time with guests.
- Simple ingredients – chocolate, eggs, cream, sugar, vanilla, and hazelnuts.
- Rich but balanced – the salt on the roasted hazelnuts lifts the chocolate, making each bite irresistible.
- Elegant presentation – serve in little bowls, glasses, or coupes for that restaurant-style look.
Ingredients Explained
- Dark chocolate – go for a good quality chocolate around 70% cocoa; it gives richness without being too bitter.
- Eggs – the yolks enrich the mousse while the whites make it airy and light.
- Caster sugar – sweetens and stabilises the egg whites.
- Thickened cream – whipped to soft peaks, it adds a velvety texture.
- Vanilla extract – rounds out the flavour with a gentle sweetness.
- Hazelnuts – roasted and chopped, they provide crunch and a nutty depth.
- Flaky sea salt – sprinkled while the nuts are warm, it enhances both the hazelnuts and the chocolate.
If chocolate is your weakness, my Chocolate Brownies are another must-try — gooey, rich, and perfect with a scoop of vanilla ice cream.
Pro Tips
- Whip the cream first so it’s ready to fold in while the chocolate mixture is still workable.
- Fold slowly and gently to avoid deflating the mousse.
- Salt the hazelnuts while they’re warm — it helps the flakes stick and intensifies the flavour.
- Add the hazelnuts just before serving to keep them crunchy.
Storage
- Keep the mousse covered in the fridge for up to 2 days.
- Add the hazelnuts right before serving so they stay crisp.
FAQs
Can I use milk chocolate instead?
Yes, but reduce the sugar slightly as milk chocolate is sweeter.
What if I don’t have hazelnuts?
You can use almonds or walnuts, but hazelnuts pair especially well with chocolate.
Can I freeze chocolate mousse?
It’s best enjoyed fresh, but you can freeze it in individual containers and eat it semi-frozen as a “frozen mousse.”
Wine Pairing
This dessert pairs beautifully with a dessert wine like a tawny port, or try a nutty sherry (Amontillado) to echo the hazelnut notes. For something lighter, a sparkling rosé makes a lovely contrast.
Final Thoughts
This chocolate mousse with salted hazelnuts is everything I want in a dessert — make-ahead, elegant, and incredibly satisfying. I love that I can prepare it the night before and simply take it out of the fridge when it’s time to serve, no fuss required. Whether you’re hosting friends or putting together a family meal, this recipe is a guaranteed crowd-pleaser.
Chocolate Mousse with Salted Hazelnuts
Equipment
- Heatproof bowl (for melting chocolate)
- Saucepan (for bain-marie method)
- Electric beaters (for cream and egg whites)
- Mixing Bowls
- Rubber spatula (for folding)
- Baking tray (for roasting hazelnuts)
- Serving bowls or coupes
Ingredients
- 200 g good-quality dark chocolate around 70% cocoa
- 3 large eggs separated
- ¼ cup 55 g caster sugar
- 300 ml thickened cream
- 1 tsp vanilla extract
- Pinch of salt
- 50 g skinless hazelnuts
- Flaky sea salt for finishing
Instructions
- Whip the cream – Using electric beaters, whip the cream with vanilla until soft peaks form. Cover and refrigerate until needed.
- Melt the chocolate – Break the chocolate into pieces and place in a heatproof bowl. Set over a pan of barely simmering water (or microwave in short bursts) until smooth. Set aside to cool slightly.
- Mix in egg yolks – Lightly beat the egg yolks in a small bowl. Slowly stir them into the cooled chocolate until glossy.
- Whip the egg whites – In a clean bowl, use electric beaters to beat the egg whites with a pinch of salt until soft peaks form. Gradually add the sugar, whisking until firm peaks form.
- Fold together – Fold one-third of the egg whites into the chocolate to lighten. Gently fold in the remaining egg whites, then the whipped cream. Work slowly to keep the mousse airy.
- Chill to set – Spoon the mousse into a large serving bowl or individual little bowls. Cover and refrigerate for at least 4 hours, or preferably overnight, until firm.
- Prepare the hazelnuts – Place skinless hazelnuts on a baking tray and roast in a 180°C (fan 160°C) oven for 8–10 minutes, or until golden and fragrant. Roughly chop and sprinkle with a pinch of flaky sea salt while still warm, so the salt clings.
- Serve – Sprinkle generously with the salted hazelnuts just before serving.
Such a beautiful looking desert !
