Steps

Step 1: Make the Brownie Base

1. Preheat the oven to 350°F (175°C) and line a 9-inch springform pan with parchment paper.
2. In a large bowl, whisk melted butter and sugar. Add eggs and vanilla, whisking until smooth.
3. Mix in cocoa powder, flour, and salt until just combined. Do not overmix.
4. Pour the batter into the prepared pan and bake for 20-25 minutes. Let the brownie cool completely.

Step 2: Prepare the Chocolate Mousse Layers

1. Dark Chocolate Mousse: Heat 1 cup heavy cream until steaming. Pour over dark chocolate chips in a bowl. Let sit for 2 minutes, then whisk until smooth. Allow to cool slightly. In another bowl, whip 1 cup heavy cream with 1 tbsp powdered sugar until stiff peaks form. Fold into the cooled chocolate mixture. Spread over the brownie base and refrigerate for 1 hour.
2. Milk Chocolate Mousse: Repeat the same process with milk chocolate chips and another 1 cup heavy cream with 1 tbsp powdered sugar. Spread over the dark chocolate mousse layer and refrigerate for 1 hour.
3. White Chocolate Mousse: Repeat the process with white chocolate chips and the final 1 cup heavy cream with 1 tbsp powdered sugar. Spread over the milk chocolate mousse layer and refrigerate for 1 hour.

Step 3: Make the Ganache Topping

1. Heat ½ cup heavy cream until steaming and pour over semi-sweet chocolate chips. Let sit for 2 minutes, then whisk until glossy.
2. Pour the ganache over the top of the chilled mousse layers and spread evenly. Chill for another hour or until set.

Step 4: Garnish and Serve

1. Once the ganache is set, remove the cake from the springform pan.
2. Decorate with chocolate curls, fresh berries, or a dollop of whipped cream for a luxurious finish.
3. Slice and serve chilled for the best texture and presentation.

Optional Additions

• Add crushed cookies or nuts between the mousse layers for added crunch.
• Drizzle caramel sauce over the ganache for extra decadence.
• Replace the brownie base with a cookie crust for a lighter variation.

Pro Tips
