Instructions
Step 1
Step 2
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
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
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.

Servings
Equipment
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.
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.
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.
Essential for smooth mousse layers and easy cake removal. If unavailable, parchment paper strips could be a substitute, but acetate is easier to handle.
Variations
Faq
- How do I prevent my sponge from deflating?
Make sure to gently fold the whipped egg whites into the batter instead of stirring vigorously, and bake your sponge cake immediately to maintain its airy structure.
- Can I use store-bought mousse instead?
Absolutely! While homemade mousse is delightful, store-bought mousse can save time and still deliver great taste and texture.
- How do I achieve smooth mousse layers?
Whip your cream until stiff peaks form, and make sure the gelatin is fully dissolved before mixing. Pour the mousse slowly to avoid air bubbles.
- Can I prepare the cake in advance?
Yes, this cake is ideally made a day ahead to allow the mousse layers to set properly. Store it in the fridge to keep it fresh.
- What’s the best way to decorate this cake?
Get creative! Chocolate glaze, fresh berries, edible flowers, or even some artistic chocolate curls can make your cake look both elegant and inviting.
- Can I freeze this mousse cake?
Yes, you can freeze the cake. Just make sure it's tightly wrapped, and allow it to defrost slowly in the fridge before serving.
