Ingredients

  • Milk Chocolate Mousse:
  • 200g milk chocolate
  • ¼ cup (60 ml) whole milk
  • 1 teaspoon vanilla extract
  • ¼ cup (25g) toasted blanched hazelnuts, finely chopped
  • 1 cup (240 ml) heavy cream
  • Chocolate Hazelnut Ganache:
  • 60g milk chocolate
  • ¼ cup (60 ml) heavy cream
  • 2 tablespoons hazelnut spread (such as Nutella)
  • ¼ teaspoon dark rum, optional
  • Topping:
  • ¼ cup (25g) blanched hazelnuts, toasted and coarsely chopped

Instructions

  1. Place milk chocolate and milk in a heatproof bowl. Melt in the microwave or over a double boiler until smooth. Stir in vanilla and finely chopped hazelnuts. Let the mixture cool to room temperature.
  2. In a separate bowl, beat the heavy cream until soft peaks form. Fold half of the whipped cream into the cooled chocolate mixture, then gently fold in the remaining cream until fully incorporated.
  3. Divide the mousse evenly among 4–6 serving glasses, leaving room at the top for ganache.
  4. To make the ganache, place milk chocolate in a bowl. Heat the cream until just boiling, then pour over the chocolate. Let sit for 1 minute, then whisk until smooth. Stir in hazelnut spread and rum (if using). Let cool slightly.
  5. Spoon ganache evenly over the mousse. Top with coarsely chopped toasted hazelnuts.
  6. Chill the assembled mousse cups for at least 2 hours before serving.

Notes

  • Use good-quality milk chocolate (30–40% cocoa) for the best flavor and texture.
  • To toast hazelnuts: bake at 350°F (175°C) for 6–8 minutes, stirring once halfway through.
  • The rum is optional and can be replaced with hazelnut liqueur or omitted.
  • Chill well to allow mousse to set—at least 2 hours or overnight for best results.
  • Use a piping bag for a neater mousse layer in cups, if desired.
