📝 Ingredients You’ll Need

For the Base (choose one):

• 1/4 cup melted butter

OR

• 1 box brownie mix, baked in a round pan (cool before using)

For the Chocolate Mousse:

• 1 1/4 cups semisweet or dark chocolate chips
• 2 tablespoons unsalted butter
• 2 teaspoons vanilla extract
• 3 eggs, separated
• 1/4 cup granulated sugar
• 1 cup heavy whipping cream (cold)

For Topping (optional but recommended):

🍰 How to Make Chocolate Mousse Cake

Step 1: Prepare the Base

Mix crushed cookies with melted butter and press into a springform pan lined with parchment paper. Use the bottom of a glass to pack it firmly. Chill in the fridge while you prepare the mousse. If using brownies, bake in the pan and let it cool completely.

Step 2: Melt the Chocolate

In a heatproof bowl, melt chocolate chips and butter together over a double boiler (or microwave in 20-second intervals), stirring until smooth. Let it cool slightly.

Step 3: Whip the Egg Yolks

In a small bowl, beat egg yolks with vanilla until pale and creamy. Add to the cooled chocolate mixture and stir gently.

Step 4: Beat the Egg Whites

In a clean bowl, beat the egg whites until soft peaks form. Add sugar slowly and continue beating until stiff peaks form. Fold the whites gently into the chocolate mixture.

Step 5: Whip the Cream

In a separate bowl, whip the heavy cream until stiff peaks form. Carefully fold it into the chocolate mixture until smooth and fully combined.

Step 6: Assemble the Cake

Pour the mousse mixture over the chilled crust or brownie base. Smooth the top and tap the pan gently to remove air bubbles.

Step 7: Chill

Cover and refrigerate the cake for at least 4 hours, or overnight for best texture.

Step 8: Decorate and Serve

Before serving, top with whipped cream, chocolate curls, or berries. Release the cake from the springform pan carefully and slice with a hot knife for clean edges.

🧊 Storage Tips

• Refrigerator: Store leftovers in the fridge for up to 4 days.
• Freezer: You can freeze the cake (without toppings) for up to 1 month. Thaw in the refrigerator overnight.
