  • Total Time: 2 hrs 30 mins
  • Yield: 12 servings 1x

Ingredients

Scale
  • For the chocolate cake base: 1/2 cup all-purpose flour
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup granulated sugar
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon salt
  • 2 large eggs
  • 1/4 cup milk
  • 1/4 cup unsalted butter, melted
  • 1 teaspoon vanilla extract
  • For the raspberry mousse: 2 cups fresh raspberries
  • 3 tablespoons granulated sugar
  • 1 teaspoon lemon juice
  • 1 teaspoon gelatin dissolved in 2 tablespoons hot water (optional)
  • 1 cup heavy cream, whipped
  • For the ganache: 1/2 cup heavy cream
  • 4 oz dark chocolate (70% cacao), finely chopped
  • For assembly: Fresh raspberries for garnish
  • Powdered sugar for dusting (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line a cake pan and prepare the chocolate batter by whisking flour, cocoa, sugar, baking powder, and salt. In another bowl, whisk eggs, milk, melted butter, and vanilla; combine with dry ingredients until smooth. Bake 20–25 minutes; cool completely.
  2. Puree 2 cups raspberries with lemon juice and sugar; sprinkle gelatin in hot water if using and fold into the puree. Whip heavy cream to soft peaks and fold into the raspberry mixture to form a light mousse.
  3. Heat cream and chocolate for ganache until smooth and glossy. Let cool slightly.
  4. Assemble by layering chocolate cake with raspberry mousse, then pour ganache on top. Chill at least 2 hours until set; garnish with extra raspberries.

Notes

  • Chill the cake for at least 2 hours for clean slicing.
  • Can be made a day ahead; keep refrigerated until serving.
  • For a lighter version, substitute half of the ganache with a raspberry coulis.
  • Gluten-free option: use a gluten-free flour blend in place of the all-purpose flour.
