Chocolate Mousse Brownies Recipe
Ingredients
- FOR THE 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
- FOR THE 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
- FOR THE GANACHE TOPPING:
- 4 oz (115g) semisweet chocolate, finely chopped
- 1/2 cup (120ml) heavy cream
Instructions
- PREPARE THE PAN: Preheat the oven to 350°F (175°C) and line an 8×8-inch (20×20 cm) square baking pan with parchment paper, leaving a slight overhang on the sides for easy removal.
- MAKE THE BROWNIE BATTER: In a large bowl, whisk together the melted butter, granulated sugar, eggs, and vanilla extract until smooth and well combined.
- ADD DRY INGREDIENTS: Sift in the cocoa powder, flour, salt, and baking powder. Gently fold the dry mixture into the wet ingredients just until no streaks remain. Do not overmix.
- BAKE THE BROWNIE LAYER: Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 20 to 25 minutes until a toothpick inserted into the center comes out with a few moist crumbs. Let the brownie base cool completely in the pan.
- MAKE THE MOUSSE BASE: Heat the milk in a small saucepan over low heat until just steaming. Pour it over the chopped chocolate in a heatproof bowl. Let it sit undisturbed for 2 minutes, then stir until fully melted and smooth. Let the mixture cool to room temperature.
- WHIP THE CREAM: In a separate bowl, beat the chilled heavy cream and powdered sugar until soft peaks form.
- FOLD TO COMBINE: Stir a spoonful of whipped cream into the cooled chocolate mixture to loosen it. Gently fold the remaining whipped cream into the chocolate until fully blended and airy. Avoid deflating the mousse.
- ASSEMBLE MOUSSE LAYER: Spread the chocolate mousse evenly over the cooled brownie base using a spatula. Refrigerate the pan for at least 2 hours, or until the mousse is set.
- MAKE THE GANACHE: Place the chopped chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan until it begins to simmer. Pour the hot cream over the chocolate and let sit for 2 to 3 minutes. Stir until smooth and glossy.
- ADD GANACHE TOPPING: Pour the ganache over the chilled mousse layer and smooth the surface with an offset spatula. Return the pan to the refrigerator for 1 hour, or until the ganache is firm.
- SLICE AND SERVE: Once fully set, lift the dessert out of the pan using the parchment overhang. Slice with a clean, sharp knife, wiping between cuts for neat edges.
