Method

Cake Preparation

  1. 1

    Melt Chocolate and Butter

    In a heatproof bowl, melt dark chocolate and butter over a pot of simmering water. Stir until smooth and set aside to cool slightly.

  2. 2

    Mix Wet Ingredients

    In a separate bowl, whisk together sugar and eggs until light and fluffy. Add the melted chocolate mixture and mix until combined.

  3. 3

    Combine Dry Ingredients

    In another bowl, mix flour and baking powder. Gradually add to the wet mixture, folding in gently until just combined. Fold in toffee bits.

  4. 4

    Bake the Cake

    Preheat the oven to 180°C (350°F). Pour the batter into a greased cake pan and bake for 25-30 minutes or until a toothpick comes out clean. Let it cool completely.

Mousse Preparation

  1. 5

    Prepare Gelatin

    In a small bowl, dissolve gelatin in water and let it sit for about 5 minutes.

  2. 6

    Whip Cream

    In a mixing bowl, whip the heavy cream and powdered sugar until soft peaks form. Gradually add the dissolved gelatin and vanilla extract while continuing to whip until stiff peaks form.

  3. 7

    Combine with Cake

    Once the cake is cooled, spread the mousse on top of the cake evenly. Refrigerate for at least 2 hours to set.

Serve

  1. 8

    Garnish and Serve

    Slice the mousse cake and serve with mixed berries, raspberry puree, chocolate sauce, and a dollop of whipped cream on the side.
