What Kind of Chocolate Should I Use?

For the richest chocolate flavor, use high-quality semi-sweet chocolate bars or chips. Avoid milk chocolate, which can make the mousse overly sweet. Couverture chocolate is ideal if you have access to it, but any smooth-melting semi-sweet chocolate will do beautifully.

Granulated sugar – Sweetens the mousse without overwhelming it.

Vanilla extract – Enhances the chocolate and mint notes.

Peppermint extract – Infuses the topping with classic minty freshness.

How To Make the Mint Chocolate Mousse Cake

Step 1: Make the Crust

Crush 24 Oreo cookies (filling included) into fine crumbs using a food processor. Mix with 6 tablespoons of melted unsalted butter until evenly combined. Press into the bottom of a 9-inch springform pan. Chill in the fridge while preparing the filling.

Step 2: Prepare the Chocolate Mousse

Melt 8 ounces of semi-sweet chocolate using a double boiler or microwave in short bursts. Let it cool slightly. In a large bowl, beat 8 ounces of softened cream cheese with 1/2 cup granulated sugar and 1 teaspoon vanilla extract until smooth. Fold in the melted chocolate.

Whip 1 1/2 cups of heavy whipping cream until stiff peaks form. Gently fold it into the chocolate mixture in batches until fully combined. Pour over the chilled crust and smooth the top. Refrigerate for at least 4 hours or until set.

Step 3: Make the Mint Whipped Topping

Whip 1 cup heavy whipping cream with 1/4 cup powdered sugar and 1/2 teaspoon peppermint extract until soft peaks form. Fold in 1 tablespoon finely chopped fresh mint leaves. Pipe or spoon over the set mousse layer.

Step 4: Garnish and Serve

Top with dark chocolate shavings or curls and a few mint sprigs for presentation. Slice and enjoy!

Frequently Asked Questions

Can I use milk chocolate instead of semi-sweet?
Semi-sweet chocolate offers a richer flavor and balances the sweetness better, but milk chocolate can be used for a sweeter, milder version.

Can I make it ahead of time?
Absolutely! You can prepare the crust and mousse up to 2 days in advance. Add the mint topping and garnishes right before serving.

Do I need a springform pan?
While it’s ideal for easy release, you can use a regular 9-inch round pan lined with parchment paper. Just lift the cake out carefully.

Can I skip the fresh mint in the topping?
Yes, but fresh mint adds visual appeal and a natural flavor. You can replace it with a drop of green food coloring if you want a minty hue without the herbs.

Is this cake gluten-free?
It can be made gluten-free by using gluten-free chocolate sandwich cookies in place of Oreos.
