Ingredients

Scale

Base:

1 1/2 cups crushed Oreo cookies or chocolate biscuits
1/4 cup melted butter

Dark Chocolate Mousse:

4 oz dark chocolate (70% cocoa recommended)
1 cup heavy cream
1 tbsp sugar
1 tsp unflavored gelatin (optional for stability)

Milk Chocolate Mousse:

4 oz milk chocolate
1 cup heavy cream
1 tbsp sugar
1 tsp unflavored gelatin (optional)

White Chocolate Mousse:

4 oz white chocolate
1 cup heavy cream
1 tbsp sugar
1 tsp unflavored gelatin (optional)

Optional Toppings:

Chocolate curls
Cocoa powder for dusting
Fresh berries

Instructions

Prepare the Base: Combine the crushed Oreo cookies or chocolate biscuits with melted butter. Press this mixture firmly into the bottom of a springform pan to form an even, solid crust. Place in the refrigerator to chill while preparing the mousse layers.
Make Dark Chocolate Mousse: Melt the dark chocolate and allow it to cool slightly. Whip the heavy cream with sugar until soft peaks form. If using gelatin, dissolve it in warm water and stir it into the melted chocolate. Gently fold the whipped cream into the melted chocolate mixture until well combined. Spread this mousse evenly over the chilled base layer. Refrigerate for 30 minutes to set.
Make Milk Chocolate Mousse: Repeat the same melting and whipping process with milk chocolate, heavy cream, and sugar. Include gelatin if desired. Spread this mousse carefully over the set dark chocolate layer to maintain distinct layers. Chill for another 30 minutes to set.
Make White Chocolate Mousse: Prepare the white chocolate mousse in the same fashion—melt chocolate, whip cream with sugar, optionally add gelatin, and gently fold them together. Spread this final mousse layer gently on top of the milk chocolate mousse layer.
Chill Completely: Refrigerate the assembled cake for at least 4 hours, ideally overnight, to allow all mousse layers to fully set for clean, firm layers.
Decorate and Serve: Before serving, garnish the cake with chocolate curls, a dusting of cocoa powder, or fresh berries for an elegant finish. Use a warm knife to slice through the mousse layers cleanly. Serve chilled for the best texture and flavor.

Notes

For a firmer mousse, unflavored gelatin is recommended but can be omitted for a lighter texture.
Use a warm knife when slicing to achieve clean layers and prevent mousse from cracking.
Chilling time is important for mousse to set properly; overnight refrigeration is best.
Choose high-quality chocolate for the best flavor impact.
Ensure each mousse layer is fully chilled before adding the next to maintain distinct layers.
