A decadent and airy Chocolate Hazelnut Mousse made with rich dark chocolate, whipped cream, and crunchy roasted hazelnuts. Perfect as an elegant dessert to impress guests or enjoy a luxurious treat at home.

Ingredients

Chocolate Base

  • 200 g high-quality dark chocolate (70% cocoa)

Dairy

  • 300 ml heavy cream

Eggs and Sugar

  • 3 large egg whites
  • 75 g granulated sugar

Nuts

  • 100 g roasted hazelnuts (unsalted)

Instructions

  1. Melt Chocolate: Melt the dark chocolate in a heatproof bowl over simmering water until smooth, ensuring not to let any water mix with the chocolate.
  2. Whip Cream: In a separate bowl, whip the heavy cream until soft peaks form, being careful not to over-whip to avoid turning it into butter.
  3. Beat Egg Whites: Beat the egg whites until frothy, then gradually add the granulated sugar while continuing to beat until stiff peaks form.
  4. Combine Chocolate and Cream: Gently fold the melted chocolate into the whipped cream until well incorporated and smooth.
  5. Incorporate Egg Whites: Carefully fold the beaten egg whites into the chocolate-cream mixture, maintaining as much airiness as possible.
  6. Add Hazelnuts: Fold in the finely chopped roasted hazelnuts, reserving some to garnish the top of the mousse.
  7. Chill: Spoon the mousse mixture into serving dishes and refrigerate for at least two hours to set and chill thoroughly before serving.

Notes

  • Use high-quality chocolate with at least 70% cocoa content for the best rich flavor.
  • Ensure the bowl and utensils are dry when melting chocolate to prevent seizing.
  • Do not over-whip the cream to avoid it turning grainy or buttery.
  • Fold ingredients gently to keep the mousse light and airy.
  • Roast hazelnuts yourself if possible for fresher and more robust flavor.
  • This mousse can be garnished with extra chopped hazelnuts or a dusting of cocoa powder.
  • For food safety, ensure egg whites are pasteurized or use fresh eggs from a trusted source as this recipe uses raw egg whites.
