Ingredients

Scale
  • 1 ½ cups (150 g) graham cracker crumbs or digestive biscuits, finely crushed
  • 6 tablespoons (85 g) unsalted butter, melted
  • 2 cups (480 ml) heavy cream, chilled
  • 6 oz (170 g) semi-sweet chocolate, chopped or chips
  • ½ cup (60 g) powdered sugar
  • 1 teaspoon vanilla extract
  • 4 oz (115 g) semi-sweet or bittersweet chocolate, chopped
  • ½ cup (120 ml) heavy cream
  • 1 tablespoon (14 g) unsalted butter (optional)

Instructions

  1. Prepare the Base Layer (10 minutes): Combine the crushed graham crackers and melted butter in a bowl. Stir until the crumbs are evenly coated and hold together when pressed. Press this mixture firmly into the bottom of your springform pan or serving dish. Use the back of a spoon or a flat-bottomed glass to make it compact and level. Chill in the fridge while you make the mousse.
  2. Make the Chocolate Mousse (15 minutes): Melt the chocolate gently over a double boiler or in short bursts in the microwave, stirring every 20 seconds to avoid burning. Let it cool slightly but don’t let it harden. Meanwhile, whip the cold heavy cream with powdered sugar and vanilla extract until soft peaks form (about 3-4 minutes with a mixer). Fold about a third of the whipped cream into the melted chocolate carefully to lighten it. Then fold in the rest in gentle strokes to keep the mousse air…
  3. Prepare the Chocolate Ganache (10 minutes): Heat the cream in a small saucepan until just simmering (don’t boil). Pour the hot cream over the chopped chocolate in a heatproof bowl. Let it sit for a minute, then whisk gently until smooth and glossy. Stir in butter if using for extra shine. Let ganache cool for a few minutes until it thickens but is still pourable. Pour over the mousse layer and spread evenly. Chill the entire dessert for 2-3 hours or overnight for best texture.
  4. Serve: Run a knife around the pan edges before releasing the springform. Slice with a sharp knife dipped in hot water for clean cuts. Enjoy chilled, maybe with a few fresh berries or a dollop of whipped cream.

Notes

Chill heavy cream before whipping for best volume. Melt chocolate slowly to avoid burning. Fold whipped cream gently into chocolate to keep mousse airy. Let ganache cool until thick but pourable before spreading. Chill dessert thoroughly for clean slicing. For dairy-free, use coconut cream and dairy-free chocolate. For gluten-free, substitute crust with almond flour or gluten-free cookies. Fresh berries can be added between layers for a seasonal twist.
