Ingredients

Scale

Brownie Base

  • 1/2 cup (115g) unsalted butter, melted
  • 1 cup (200g) granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/3 cup (40g) unsweetened cocoa powder
  • 1/2 cup (65g) all-purpose flour
  • 1/4 tsp salt
  • 1/4 tsp baking powder

Chocolate Mousse

  • 1 1/2 cups (350ml) heavy whipping cream, chilled
  • 8 oz (225g) semisweet chocolate, finely chopped
  • 3 tbsp (45ml) milk
  • 2 tbsp (25g) powdered sugar

Ganache Topping

  • 4 oz (115g) semisweet chocolate, finely chopped
  • 1/2 cup (120ml) heavy cream

Instructions

  1. Prepare the Brownie Batter: In a medium bowl, combine the melted butter and granulated sugar until smooth. Beat in the eggs one at a time, then add the vanilla extract. Sift together cocoa powder, all-purpose flour, salt, and baking powder, and gradually fold them into the wet ingredients to form a thick batter.
  2. Bake the Brownie Base: Preheat the oven to 350°F (175°C). Pour the batter into a greased 8-inch square baking pan, smoothing the top. Bake for 20–25 minutes, or until a toothpick inserted comes out with moist crumbs. Allow the brownies to cool completely in the pan.
  3. Make the Chocolate Mousse: In a heatproof bowl, combine the semisweet chocolate and milk. Melt gently over a double boiler or in short bursts in the microwave, stirring until smooth. In a separate chilled bowl, whip the heavy cream with powdered sugar until soft peaks form. Fold one-third of the whipped cream into the melted chocolate to lighten the mixture, then gently fold in the remaining whipped cream until fully incorporated.
  4. Assemble the Layers: Spread the chocolate mousse evenly over the cooled brownie base. Refrigerate for at least 1 hour to set the mousse layer firmly.
  5. Prepare the Ganache Topping: Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. Pour the hot cream over the chopped semisweet chocolate in a bowl. Let it sit for 2 minutes, then stir until silky and smooth. Allow the ganache to cool slightly but remain pourable.
  6. Finish the Brownies: Pour the ganache evenly over the chilled mousse layer, smoothing the top with a spatula. Refrigerate the entire dessert for another 1-2 hours to allow the ganache to set before slicing and serving.

Notes

  • Ensure the brownies are completely cooled before adding the mousse layer to prevent melting or mixing.
  • Use high-quality semisweet chocolate for the best flavor in mousse and ganache.
  • For a firmer mousse, chill it longer before adding ganache.
  • Store brownies in the refrigerator and consume within 3-4 days for optimal freshness.
  • Bring brownies to room temperature for about 15 minutes before serving for best texture and flavor.
