Brownie Base
- 6 oz (170g) dark chocolate (at least 70% cocoa), chopped
- 1/2 cup (115g) unsalted butter
- 3/4 cup (150g) granulated sugar
- 3 large eggs, room temperature
- 1 tsp vanilla extract
- 1/2 cup (65g) all-purpose flour
- 1/4 cup (25g) unsweetened cocoa powder
- Pinch of salt
Chocolate Mousse
- 1 cup (240ml) heavy cream
- 3 oz (85g) dark chocolate (at least 70% cocoa), chopped and melted
- Prepare the Brownie Base: Melt 6 oz dark chocolate and 1/2 cup unsalted butter gently over a double boiler or in short microwave bursts, stirring until smooth. In a separate bowl, whisk 3 eggs with 3/4 cup sugar and 1 tsp vanilla extract until light and fluffy. Combine the egg mixture with the melted chocolate and butter. Sift in 1/2 cup flour, 1/4 cup cocoa powder, and a pinch of salt. Fold gently to keep the batter airy and well mixed. Pour batter into a lined baking pan and bake at 350°F (175°C) for 20 minutes or until a toothpick inserted comes out with moist crumbs.
- Make the Chocolate Mousse: While the brownies cool, whip 1 cup heavy cream until soft peaks form. Melt 3 oz dark chocolate and let it cool slightly. Gently fold the melted chocolate into the whipped cream to create a light, luscious mousse.
- Assemble: Spread the chocolate mousse evenly over the cooled brownie base using a spatula to smooth the surface. Refrigerate for at least 2 hours until the mousse is set and firm enough to slice.
- Slice and Serve: Cut the chilled brownies into squares with a sharp knife, wiping the blade clean between cuts for neat edges. Serve chilled for the best flavor and texture.
Notes
- Use high-quality dark chocolate with at least 70% cocoa content for the best flavor.
- Fold dry ingredients gently to avoid dense brownies.
- Whip cream just until soft peaks form to keep mousse light and fluffy.
- Chill mousse layer adequately for clean slicing and perfect texture.
- Bring eggs and butter to room temperature before mixing.
- For clean slices, dip the knife in hot water and wipe dry between cuts.
