Instructions

Preparation

  • Preheat your oven to 175°C (350°F) and line the bottom of a springform pan with baking paper.

  • Pour the mixture into the pan and bake for 20–25 minutes until set, but still fudgy.
  • Cool in the pan completely before adding mousse.

Milk Chocolate Mousse

  • If using gelatin, bloom it in cold water, then gently melt. Melt the milk chocolate and let it cool slightly.
  • Whip cream to soft peaks, then gently fold it into the cooled milk chocolate (with gelatin, if using).
  • Pour the milk chocolate mousse over the cooled base and chill for 30–60 minutes.

White Chocolate Mousse

  • Melt the white chocolate and let it cool slightly. Repeat the folding method with whipped cream.
  • Gently add white chocolate mousse on top of the milk chocolate layer and chill the whole cake for 4–6 hours or overnight.
