Ingredients
Scale
Brownie Base
- ½ cup unsalted butter
- 1 cup sugar
- 2 large eggs
- 1 tsp vanilla extract
- â…“ cup cocoa powder
- ½ cup flour
- ¼ tsp salt
- ¼ tsp baking powder
Chocolate Mousse
- 1 ½ cup heavy whipping cream, divided
- 8 oz semisweet chocolate
- 3 tbsp milk
- 2 tbsp powdered sugar
Chocolate Ganache
- 4 oz semisweet chocolate, chopped
- ½ cup heavy cream
Instructions
- Prepare the Pan and Oven: Line an 8×8-inch baking pan with parchment paper, leaving an overhang on the sides to easily lift out the brownies later. Preheat the oven to 350°F (175°C).
- Make the Brownie Batter: Melt the unsalted butter and whisk it together with the sugar, eggs, and vanilla extract until smooth and well combined.
- Incorporate Dry Ingredients: Sift together the cocoa powder, flour, salt, and baking powder to remove lumps. Gently fold this dry mixture into the wet ingredients until just combined, being careful not to overmix to keep the brownies tender.
- Bake the Brownies: Pour the batter into the prepared pan and smooth the surface with a spatula. Bake for 20 to 25 minutes or until a toothpick inserted near the center comes out with a few moist crumbs. Allow to cool completely in the pan.
- Prepare Chocolate for Mousse: Heat the milk until steaming but not boiling. Pour the hot milk over the 8 oz semisweet chocolate and let it sit for 2 minutes. Stir gently until the mixture is smooth and glossy. Allow to cool to room temperature.
- Whip the Cream for Mousse: In a chilled bowl, beat 1 ½ cups heavy whipping cream with powdered sugar until soft peaks form.
- Fold Cream into Chocolate: To lighten the chocolate, fold in a spoonful of whipped cream first, then gently fold in the remaining whipped cream until fully incorporated and mousse-like.
- Assemble Mousse Layer: Spread the chocolate mousse evenly over the cooled brownie base. Refrigerate for at least 2 hours to set.
- Prepare Chocolate Ganache: Simmer ½ cup heavy cream and pour it over the chopped 4 oz semisweet chocolate. Let this sit for 2 to 3 minutes, then stir until smooth and shiny.
- Top with Ganache: Pour the ganache over the set mousse layer and smooth the surface with a spatula. Chill the assembled brownies for an additional hour to firm the top layer.
- Serve: Use the parchment paper overhang to lift the brownies out of the pan. Slice with a hot, clean knife, wiping the blade between cuts for neat slices. Serve chilled and enjoy.
Notes
- Ensure the brownies are completely cooled before adding the mousse layer to prevent melting.
- Use high-quality semisweet chocolate for the best flavor and texture.
- Chilling times are important for setting each layer properly to achieve clean slices.
- For easier slicing, warm the knife blade under hot water and dry it before each cut.
- This dessert can be made a day ahead and stored in the refrigerator.
