For the mousse filling:

Instructions
1. Crafting the Brownie Base
Preheat your oven to 350°F and prepare an 8-inch springform pan by lightly spraying it with nonstick spray and lining it with parchment paper. Combine the unsweetened chocolate and butter in a medium saucepan over medium-low heat, stirring constantly until smooth. Remove from heat and whisk in the sugar. Allow the mixture to cool slightly before adding eggs and vanilla extract, ensuring the eggs don’t scramble.
Sift the flour, cocoa powder, and salt into the chocolate mixture. Using a rubber spatula, gently fold the dry ingredients into the wet mixture until just combined. Be cautious not to overmix, as this can make the brownie dense. Spread the batter evenly in the pan and bake for 20–25 minutes. Allow the brownie to cool completely in the pan on a wire rack or chill it in the refrigerator for faster results.
2. Preparing the Mousse
Sprinkle gelatin over water in a small bowl and let it stand for 5 minutes. Meanwhile, place the semisweet chocolate in a medium bowl. In a saucepan, bring ½ cup heavy cream and sugar to a simmer, ensuring the sugar dissolves. Remove from heat and stir in the gelatin mixture until dissolved. Pour the warm cream mixture over the chocolate and whisk until smooth. Let the mixture cool to room temperature, stirring occasionally.
In a stand mixer, whip the remaining cream to medium-stiff peaks. Add a third of the whipped cream to the cooled chocolate mixture and whisk to lighten it. Gently fold in the remaining whipped cream using a spatula until no streaks remain. Spread the mousse over the cooled brownie base and refrigerate.
3. Making the Ganache
Heat cream and butter in a saucepan until just before boiling. Pour over the chopped chocolate and stir until smooth. Allow the ganache to cool until it is no longer warm to the touch. Spread it evenly over the mousse layer. Refrigerate the assembled cake for at least one hour to set.
Finishing Touches
Once set, carefully remove the cake from the springform pan, peeling away the parchment paper. Slice with a warm knife for clean edges, and serve chilled with whipped cream or fresh berries.
Notes
- Choose high-quality chocolate: The flavor of your cake depends heavily on the chocolate you use. Opt for premium unsweetened and semisweet varieties.
- Room temperature ingredients: Ensure your eggs and butter are at room temperature for the brownie layer to achieve the best texture.
- Refrigeration is key: Chilling each layer adequately ensures a perfect structure and clean layers when sliced.
- Adaptations: Use milk or dark chocolate for a different flavor profile in the mousse and ganache. Short on time? Replace the whipped cream with store-bought Cool Whip for convenience.
