Ingredients

Scale

Cake Base

  • 1 cake base (such as chocolate or sponge cake, about 8 inches in diameter)

Chocolate Mousse

  • 200g dark chocolate, chopped
  • 3 large eggs, separated
  • 75g granulated sugar
  • 150ml heavy cream
  • 50g unsalted butter

Instructions

  1. Prepare the chocolate: Melt the dark chocolate and butter together using a double boiler or microwave in short bursts, stirring frequently until smooth and glossy. Set aside to cool slightly.
  2. Whip egg yolks and sugar: In a bowl, whisk the egg yolks with half the sugar until the mixture becomes pale and creamy.
  3. Combine chocolate and yolk mixture: Gently fold the melted chocolate into the egg yolk mixture until well combined.
  4. Whip the egg whites: In a separate clean bowl, beat the egg whites until soft peaks form. Gradually add the remaining sugar and continue whipping until stiff peaks form.
  5. Whip the cream: In another bowl, whip the heavy cream until it holds soft peaks.
  6. Fold components together: Carefully fold the whipped cream into the chocolate and yolk mixture, then gently fold in the whipped egg whites to retain airiness.
  7. Assemble the cake: Place the cake base on a serving plate or cake ring. Spoon the chocolate mousse over the cake base and smooth the top evenly.
  8. Chill until set: Refrigerate the assembled cake for at least 4 hours, or preferably overnight, to allow the mousse to set properly.
  9. Serve: Remove the cake from the fridge 10 minutes before serving for best texture and flavor. Optionally garnish with chocolate shavings or fresh berries.

Notes

  • Use high-quality dark chocolate for the best flavor.
  • Ensure the melted chocolate is not too hot when mixing with eggs to prevent curdling.
  • Be gentle when folding whipped egg whites and cream to maintain mousse lightness.
  • Chilling the mousse overnight enhances the texture and flavor melding.
  • Eggs are raw or lightly cooked in mousse; use fresh, high-quality eggs or pasteurized eggs for safety.
