Chocolate Biscuit

  • 90 grams (3.15 ounces) dark chocolate
  • 100 grams (3.55 ounces) butter
  • 110 grams (3.90 ounces) sugar
  • 1 pc baking powder
  • 4 pcs eggs
  • 120 grams (4.25 ounces) flour


  • 20 milliliters (0.70 fluid ounces) milk (with high fat content) or cream

Bitter Chocolate Mousse

  • 12 grams (0.40 ounces) gelatin
  • 50 milliliters (1.75 fluid ounces) milk
  • 180 grams (6.35 ounces) bitter chocolate
  • 40 grams (1.40 ounces) butter
  • 300 milliliters (10.10 fluid ounces) cream

Milk Chocolate Mousse

  • 15 grams (0.53 ounces) gelatin
  • 70 milliliters (2.45 fluid ounces) milk
  • 180 grams (6.35 ounces) milk chocolate
  • 40 grams (1.40 ounces) butter
  • 300 milliliters (10.10 fluid ounces) cream

White Chocolate Mousse

  • 12 grams (0.40 ounces) gelatin
  • 50 milliliters (1.75 fluid ounces) milk
  • 220 grams (7.75 ounces) white chocolate
  • 20 grams (0.70 ounces) butter
  • 300 milliliters (10.10 fluid ounces) cream


  • Water Bath (Double Boiler)

    A heatproof bowl set over simmering water helps gently melt chocolate and butter without burning. If you don't have one, a heatproof mixing bowl over a saucepan works perfectly.

  • Electric Mixer

    From whipping egg whites to mixing butter and sugar, an electric mixer saves time and ensures a smooth, creamy texture. Hand mixers are good too, but a stand mixer offers more consistency.

  • Pastry Ring (20 cm or 7.9 inches)

    This creates a uniform shape for your cake. If you don’t have one, springform pans can work, but a pastry ring with acetate lining guarantees flawless layers.

  • Acetate Film

    Essential for smooth mousse layers and easy cake removal. If unavailable, parchment paper strips could be a substitute, but acetate is easier to handle.


Step 1

The perfect cake looks just like this! Three tastes of chocolate soufflé, from dark chocolate to white chocolate, with a soft, moist chocolate sponge cake. This cake will not leave anyone indifferent, even the most experienced sweet tooth.

Step 2

1 For the chocolate sponge biscuit: Heat the butter and chocolate in a double boiler to melt them together.
Stir constantly to ensure a smooth mixture. Whip the butter with the sugar until light and fluffy. Mix in the melted chocolate. Add the egg yolks one by one, mixing well after each addition. Gradually fold in the flour and baking powder. In a separate bowl, whip the egg whites to stiff peaks and gently fold them into the batter.
Take your time with this step to keep the batter airy. Bake the sponge biscuit for 40 to 45 minutes at 180°C (356°F). Allow the biscuit to cool completely, then soak it with milk or cream. Place in the fridge.

Step 3

2 To prepare the mousse: Pour the gelatin over the milk and let it sit for 5 minutes to bloom.
Heat the chocolate and the butter in a double boiler until melted. Add the bloomed gelatin and mix well. Whip the cold cream until soft peaks form and gently fold it into the chocolate mixture.
Be careful not to deflate the cream too much while folding.

Step 4

3 To assemble the cake: Trim the edges of the sponge biscuit if needed to fit into a 20 cm (7.9 inch) ring mold.
Line the inside of the ring with acetate film.
This will help to keep the layers smooth and easy to remove. Place the sponge biscuit at the bottom of the ring. Pour the dark chocolate mousse over the biscuit and refrigerate for 1 hour until set. Repeat with the milk chocolate mousse, refrigerating for another hour. Finally, pour the white chocolate mousse over the top. Refrigerate the assembled cake for at least one day to set completely.

Step 5

4 Decorate the cake: Decorate the cake as desired with chocolate glaze, fresh grapes, chocolates, or marshmallows. Be creative and have fun with your decorations!

Step 6
