Ingredients

Scale
  • 1 cup (120g) all-purpose flour
  • ¾ cup (75g) unsweetened cocoa powder
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • ¾ cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • ½ cup (120ml) whole milk
  • ½ cup (115g) unsalted butter, melted and cooled
  • 1 teaspoon pure vanilla extract
  • 6 oz (170g) dark chocolate (70% cocoa), chopped
  • 6 oz (170g) milk chocolate, chopped
  • 6 oz (170g) white chocolate, chopped
  • 3 cups (720ml) heavy cream, cold, divided
  • 6 large egg whites, room temperature
  • ½ cup (100g) granulated sugar
  • 1 teaspoon vanilla extract
  • 4 oz (115g) dark chocolate, chopped (for ganache)
  • ½ cup (120ml) heavy cream (for ganache)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and line the bottom of a 9-inch springform pan.
  2. In a medium bowl, sift together flour, cocoa powder, baking powder, and salt.
  3. In a large bowl, whisk sugar and eggs until pale and fluffy (3-4 minutes).
  4. Slowly add melted butter, milk, and vanilla extract, mixing gently.
  5. Gradually fold in dry ingredients until just combined.
  6. Pour batter into pan and bake for 20-25 minutes or until a toothpick inserted comes out with moist crumbs.
  7. Let cake cool completely in the pan on a wire rack.
  8. Divide heavy cream into three equal portions (1 cup each).
  9. Melt each type of chocolate separately using a double boiler or microwave, stirring until smooth. Cool slightly.
  10. Whip each portion of cream to soft peaks and set aside.
  11. Beat egg whites until foamy, gradually add sugar, and beat until stiff, glossy peaks form.
  12. For each chocolate type, fold melted chocolate into whipped cream until smooth, then fold in one-third of the meringue gently.
  13. Place cooled cake base in springform pan. Spread dark chocolate mousse evenly and chill 20 minutes.
  14. Repeat with milk chocolate mousse layer and chill 20 minutes.
  15. Add white chocolate mousse layer, smooth surface, and refrigerate at least 4 hours or overnight.
  16. Heat heavy cream for ganache until simmering. Pour over chopped dark chocolate, let sit 2 minutes, then stir until smooth.
  17. Cool ganache until thick but pourable, then pour over chilled mousse cake. Chill another 30 minutes before serving.

Notes

Use room temperature eggs for best meringue results. Fold mousse ingredients gently to keep airy texture. Chill each mousse layer before adding the next to maintain distinct layers. Use a hot, dry knife for clean slicing. For dairy-free, substitute heavy cream with coconut cream and use dairy-free chocolates. Almond flour can replace all-purpose flour for gluten-free version. Ganache adds a glossy, professional finish and rich flavor.
