For the dacquoise:


  • 3 oz. Egg whites
  • 1.5 oz. Sugar

  • 3 oz. Icing sugar


  1. Beat the egg whites with the sugar.
  2. Mix together the almond powder and icing sugar
  3. Pour gently on the whites
  4. Gently fold in and do not mix. Use a spatula so you don’t break the white. 
  5. Put butter on your pastry ring then place it on a baking tray covered with baking paper.

  7. Let it cool down at room temperature

For the crispy praliné:


  • 4.5 oz. Praline chocolate (or Nutella type of spread)
  • 2.5 oz. Any thin cookies


  • Mash the cookies in a bowl and pour the melted praline chocolate (or the spread on it).
  • Mix and spread in the circle on the dacquoise and put it into the freezer until the end of the recipe

For the Chocolate ganache mousse:


  • 9 oz. Whipping cream
  • 4.5 oz. of Dark chocolate (min 66% of cocoa)
  • 4.5 oz. of Milk
  • .15 oz. Gelatin (1.5 to 2 sheets)
  • 1 Pinch of salt


  • Soften the gelatin in a large amount of cold water.

To assemble the cake:

  • Optional: decorate by sprinkling with cocoa or with a few raspberries.
