Ingredients You’ll Need
This recipe uses simple, easy-to-find ingredients to create a truly gourmet dessert. Here’s what you’ll need to gather:
For the Oreo Crust:
- Oreo Cookies: You’ll need the whole cookie, filling and all.
- Unsalted Butter: Melted to bind the cookie crumbs together.
For the Mint Mousse Filling:
- Cream Cheese: Use full-fat, block-style cream cheese, softened to room temperature for a smooth, lump-free texture.
- Powdered Sugar: To sweeten the mousse without any graininess.
- Heavy Whipping Cream: This is essential for the light and airy texture of the mousse. Make sure it’s very cold.
- Peppermint Extract: For that classic, refreshing mint flavor. Start with a little and add more to taste.
- Green Food Coloring: Optional, but a few drops will give the mousse a lovely pastel green hue.
For the Chocolate Ganache:
- Semi-Sweet Chocolate Chips: Or a chopped semi-sweet baking bar for a richer flavor.
- Heavy Whipping Cream: This will be heated and poured over the chocolate to create the ganache.
How to Make the Perfect No-Bake Mint Chocolate Mousse Cake
Follow these simple steps to create a flawless dessert. The key is to allow adequate chilling time between layers to ensure they set up perfectly.
Step 1: Prepare the Oreo Crust
- Crush the Oreo cookies into fine crumbs using a food processor or a zip-top bag and a rolling pin.
- In a medium bowl, mix the cookie crumbs with the melted butter until well combined. The mixture should resemble damp sand.
- Press the crumb mixture firmly and evenly into the bottom of a 9-inch springform pan. Use the bottom of a glass or measuring cup to pack it tightly.
- Place the crust in the freezer to set for at least 15-20 minutes while you prepare the mousse filling.
Step 2: Create the Silky Mint Mousse
- In a large bowl, beat the softened cream cheese with an electric mixer on medium speed until smooth and creamy. Add the powdered sugar and beat until fully incorporated.
- Add the peppermint extract and a few drops of green food coloring (if using) and mix until the color is uniform.
- In a separate, chilled bowl, whip the cold heavy cream until stiff peaks form.
- Gently fold the whipped cream into the cream cheese mixture in two or three additions until just combined. Be careful not to overmix, as this will deflate the mousse.
- Spread the mint mousse evenly over the chilled Oreo crust. Use a spatula to create a smooth, level surface.
- Refrigerate the cake for at least 4-6 hours, or until the mousse layer is firm to the touch. For best results, chill overnight.
Step 3: Make the Decadent Ganache Topping
- Place the semi-sweet chocolate chips in a heatproof bowl.
- Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. Do not let it boil.
- Pour the hot cream over the chocolate chips and let it sit undisturbed for 5 minutes. This allows the heat to gently melt the chocolate.
- Whisk the mixture slowly until it becomes smooth, glossy, and completely combined.
- Let the ganache cool for about 10-15 minutes, then pour it over the set mint mousse layer. Gently tilt the pan to spread the ganache evenly.
- Return the cake to the refrigerator to allow the ganache to set, which should take about 1-2 hours.
Pro-Tips for a Flawless Mousse Cake
Achieve dessert perfection with these simple but effective tips.
- Use a Springform Pan: This is crucial for easy removal and beautifully clean sides.
- Room Temperature Cream Cheese: To avoid lumps in your mousse, ensure your cream cheese is fully softened before you begin.
- Cold Heavy Cream: For the fluffiest whipped cream and a light mousse, your heavy cream and mixing bowl should be very cold.
- Patience is Key: Don’t rush the chilling times! Each layer needs to be fully set before you add the next to prevent them from bleeding into each other. For an even more decadent treat, consider pairing it with a rich homemade alfredo sauce for a savory main course first.

You can also freeze the cake for up to 2 months. To freeze, let it set completely, then wrap it tightly in plastic wrap and aluminum foil. Thaw it in the refrigerator overnight before serving.
