🛒 Ingredients

For the Crust

• 2 cups chocolate cookie crumbs (e.g., Oreos, filling removed)
• ½ cup unsalted butter, melted

For the Chocolate Mousse Filling

• 2 cups semisweet or dark chocolate chips 🍫
• 1½ cups heavy whipping cream (divided)
• ¼ cup powdered sugar
• 1 teaspoon vanilla extract

For the Topping

• 1 cup heavy whipping cream
• 2 tablespoons powdered sugar
• Chocolate shavings or cocoa powder (for garnish, optional)

🥣 How to Make No-Bake Chocolate Mousse Cake

Step 1: Prepare the Crust

1. Crush the cookies: Remove the filling from the Oreos and crush the cookies into fine crumbs using a food processor or rolling pin.
2. Mix with melted butter: In a bowl, combine the cookie crumbs and melted butter, stirring until the crumbs are evenly coated.
3. Press into the pan: Transfer the mixture to a 9-inch springform pan and press firmly into the bottom. Refrigerate while you prepare the mousse.

Step 2: Make the Chocolate Mousse Filling

1. Melt the chocolate: In a heatproof bowl, melt the chocolate chips with ½ cup heavy cream over a double boiler or in the microwave (30-second intervals, stirring in between). Let cool slightly.
2. Whip the cream: In a separate bowl, beat 1 cup heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form.
3. Fold in the chocolate: Gently fold the melted chocolate mixture into the whipped cream until smooth and fully combined.
4. Pour over crust: Spread the mousse evenly over the chilled crust and refrigerate for at least 4 hours (or overnight) until set.

Step 3: Prepare the Whipped Topping

1. Whip the cream: In a clean bowl, beat 1 cup heavy cream and powdered sugar until soft peaks form.
2. Spread over the mousse: Once the mousse has set, spread or pipe the whipped topping over the cake.
3. Garnish & serve: Sprinkle with chocolate shavings, cocoa powder, or extra cookie crumbs for a stunning finish!

❓ Frequently Asked Questions

Can I use milk chocolate instead of dark chocolate?

Yes! But dark chocolate gives a richer flavor and prevents the cake from being overly sweet.

What if I don’t have a springform pan?

You can use a regular pie dish or an 8×8-inch square pan, but cutting and serving might be trickier.

Can I make this dessert dairy-free?

Yes! Use coconut cream instead of heavy cream and dairy-free chocolate chips.
