Instructions

  1. Step 1: Melt 6 oz chopped dark chocolate and 2 tbsp unsalted butter in a heatproof bowl over a simmering water bath, stirring until smooth. Remove from heat and let cool slightly.
  2. Step 2: Whisk 3 large egg yolks with 1/4 cup granulated sugar in a bowl until pale and thick, about 2 minutes. Gradually fold melted chocolate mixture into yolks until combined.
  3. Step 3: In a separate bowl, beat 3 large egg whites with 1/8 tsp salt until stiff peaks form. Gently fold egg whites into chocolate mixture in three additions, preserving airiness.
  4. Step 4: Whip 1 cup heavy cream with 1 tsp vanilla extract until soft peaks form. Fold in 1/2 cup finely chopped toasted hazelnuts and 1 tbsp hazelnut liqueur if using.
  5. Step 5: Spoon half of the chocolate mousse into serving glasses. Add a layer of the hazelnut cream mixture, then top with remaining chocolate mousse.
  6. Step 6: Refrigerate for at least 4 hours until set. Garnish with extra chopped hazelnuts before serving.
