Ingredients

Chocolate Brownie Base

  • 1 oz all-purpose flour
  • ½ tsp baking powder
  • 0.7 oz dark chocolate
  • 0.7 oz butter
  • 2 tbsp milk
  • 1 large egg, room temperature
  • 1 oz sugar
  • A pinch of salt
  • 1 oz hazelnuts, toasted
  • 2 tsp cocoa powder
  • 10.5 oz cold heavy cream or whipped cream
  • 2 tsp powdered sugar
  • Chocolate Mousse Layers

Bottom Layer

  • 2 oz dark chocolate
  • 1.2 oz heavy cream
  • 1.5 g gelatine sheet
  • 3 oz cold whipped cream

Middle Layer

  • 2 oz milk chocolate
  • 1.2 oz heavy cream
  • 1.5 g gelatine sheet
  • 3 oz cold whipped cream

Top Layer

  • 2 oz white chocolate
  • 1.2 oz heavy cream
  • 1.5 g gelatine sheet
  • 3 oz cold whipped cream

Instructions

  • Preheat the oven to 350°F (180°C). Grease and line a 7-inch cake pan.
  • Melt the dark chocolate, butter, and milk for the brownie base; combine.
  • In another bowl, mix egg, salt, sugar, and vanilla.
  • Sift and mix in flour, cocoa powder, baking powder, and hazelnuts.
  • Bake in the prepared pan for 20 minutes. Allow to cool, then trim to fit a 6-inch ring.
  • Soak gelatine. Whip cream and powdered sugar to peaks.
  • For each chocolate mousse layer, melt chocolate with some heavy cream. Combine it with the whipped cream once cooled. Layer over the base and chill for 20 minutes.
  • Once all layers are added, chill the cake for at least 5 hours.
  • Smooth sides and dust with cocoa before serving.

Notes

  • Ensure each mousse layer is fully set in the refrigerator before adding the next to prevent the layers from merging.
  • Elevate the presentation by adding chocolate sprinkles, cocoa dusting, or piped whipped cream for an elegant finish.
  • For airy whipped cream, chill the mixing bowl in the freezer for 15 minutes before whipping the cream.
  • For neat slices, use a knife warmed under hot water and dried before cutting through the mousse layers.
  • The cake can be prepared a day in advance and kept chilled, with removal from the pan 45 minutes before serving to reach the ideal temperature.
  • For those preferring a slightly sweeter taste, opt for semi-sweet chocolate instead of bittersweet one.
  • While hazelnuts are optional, they contribute a crunchy texture and nutty flavor that enhances the cake.
