  • 1 tsp baking powder
  • ¾ cup (150g) granulated sugar
  • ½ tsp salt
  • 6 tbsp (85g) unsalted butter, melted
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • ⅓ cup (80ml) whole milk
  • 7 oz (200g) bittersweet chocolate, chopped
  • 1 ½ cups (360ml) heavy cream, divided
  • 2 tbsp granulated sugar

  • Pinch of salt
  • 1 ½ cups (225g) fresh or frozen raspberries
  • 3 tbsp granulated sugar
  • 1 tbsp freshly squeezed lemon juice
  • 2 tbsp water (optional, to thin coulis)

Instructions

  1. Prepare the Cake Base (15 minutes + baking): Preheat oven to 350°F (175°C). Lightly grease and flour an 8-inch springform pan. Sift together flour, cocoa powder, baking powder, and salt in a medium bowl. In a large bowl, whisk sugar and melted butter until combined. Beat in eggs one at a time, then vanilla extract.

  2. Make the Chocolate Mousse (20 minutes + chilling): Chop bittersweet chocolate and place in heatproof bowl. Heat ¾ cup heavy cream until just simmering and pour over chocolate. Let sit 2 minutes, then stir until smooth. Whip remaining ¾ cup heavy cream with sugar until soft peaks form. Beat egg whites with pinch of salt until stiff peaks form. Gently fold whipped cream into chocolate mixture, then fold in egg whites until no white streaks remain. Pour mousse over cooled cake base, smooth surface,…
  3. Prepare Raspberry Coulis (10 minutes): Combine raspberries, sugar, and lemon juice in small saucepan. Cook over medium heat, stirring occasionally, until berries break down and mixture thickens slightly (5-7 minutes). Optional: strain through fine mesh sieve to remove seeds. If too thick, add water a tablespoon at a time to desired consistency. Cool completely.
  4. Serve: Release mousse cake from springform pan. Drizzle generously with raspberry coulis. Garnish with fresh raspberries or mint if desired.

Notes

Use room temperature eggs for best mousse texture. Ensure bowls and utensils for whipping egg whites are clean and dry to achieve stiff peaks. Melt chocolate gently using a double boiler to avoid burning. Fold mousse ingredients gently to maintain airiness. Let cake cool completely before adding mousse to prevent melting. Prepare coulis while cake bakes to save time. For gluten-free, substitute flour with almond or gluten-free blend. Frozen raspberries can be used for coulis after thawing and draining excess water.
