Ingredients You’ll Need
Gathering the right ingredients is the key to mastering this delightful dessert. Each component plays an important role in balancing flavor, texture, and presentation, turning simple basics into an extraordinary pie.
- Salted butter, 2 Tbsp diced: Adds richness and helps melt the chocolate smoothly.
- Semi-sweet chocolate chips, 1 cup: Provides the primary chocolate base that’s smooth and sweet.
- Bittersweet chocolate chips, 1/2 cup: Adds depth and a slight tang to balance the sweetness.
- Mini marshmallows, 2 cups: Melts into the chocolate mixture, lending a velvety texture.
- Whole milk, 1/3 cup: Creates a creamy consistency in the chocolate base.
- Vanilla extract, 1 tsp: Enhances the chocolate flavor with a warm, aromatic note.
- Heavy whipping cream, 1 3/4 cups + 1 cup: Used both in folding into the mousse and whipping for topping to ensure lightness and fluffiness.
- Oreo pie crust, 1 crust: The crunchy and chocolatey foundation that gives the pie a satisfying bite.
- Granulated sugar, 2 Tbsp: Sweetens the whipped cream topping for a perfect balance.

How to Make Chocolate Mousse Pie with Oreo Crust and Chocolate Shavings Recipe
Step 1: Create the Decadent Chocolate Mixture
Start by gently heating the salted butter, whole milk, semi-sweet and bittersweet chocolate chips, along with mini marshmallows in a large saucepan over low heat. Stirring continuously is essential here to melt everything evenly and avoid burning. Once the marshmallows are melted completely and the chocolate mixture turns wonderfully smooth and creamy, take it off the heat. Stir in the vanilla extract to infuse aroma and flavor. Let it cool at room temperature for about an hour, so it’s ready to be combined with the whipped cream without melting it.
Step 2: Whip the Heavy Cream to Stiff Peaks
Pour 1 3/4 cups of heavy whipping cream into a large bowl and use an electric mixer to whip it until stiff peaks form. This means when you lift the mixer, the cream holds sharp peaks without falling over. It’s crucial not to overwhip – you want a luscious, airy texture that will lighten the chocolate base in the next step.
Step 3: Fold Whipped Cream into Chocolate Mixture
Gently fold the whipped cream into your cooled chocolate base using a spatula. Take your time with this to keep as much air in the mixture as possible, resulting in that signature light and fluffy chocolate mousse texture. The color should become uniform, signaling a perfect blend without losing the mousse’s airy quality.
Step 4: Pour the Mousse into the Oreo Crust
Now for the fun part: spoon your fluffy chocolate mousse into the Oreo pie crust. Use your spatula to spread it evenly from edge to edge, ensuring every bite will have that perfect layer of mousse sitting on the crisp Oreo’s chocolatey foundation.
Step 5: Refrigerate Until Set
Pop the pie into the refrigerator and chill it for at least 3 hours. This waiting period might test your patience but is vital for the mousse to firm up and achieve that melt-in-your-mouth consistency.
Step 6: Prepare the Sweetened Whipped Cream Topping
While the pie is chilling, combine 1 cup of heavy cream with 2 tablespoons of granulated sugar in a clean bowl. Whip until stiff peaks form, making sure it’s smooth and holds shape beautifully. This topping will add sweetness and a creamy contrast to the rich chocolate mousse.
Step 7: Decorate and Finish
Once chilled, spread the sweetened whipped cream evenly over the mousse layer. Generously garnish with chocolate shavings to add a touch of elegance and extra chocolate flavor. For best results, keep the pie refrigerated until ready to serve, slicing carefully to maintain clean edges.
How to Serve Chocolate Mousse Pie with Oreo Crust and Chocolate Shavings Recipe

Garnishes
While chocolate shavings are classic, you can elevate your presentation by adding fresh raspberries or a sprinkle of cocoa powder. Tiny mint leaves can add a subtle freshness that contrasts beautifully with the rich chocolate flavors.
Side Dishes
This pie stands strong on its own but pairs beautifully with a scoop of vanilla bean ice cream or a drizzle of raspberry coulis for a burst of complementary flavor. Fresh fruit slices also provide a tangy balance that cuts through the richness.
Creative Ways to Present
Serving the pie in individual clear glasses or ramekins creates an elegant, modern look perfect for dinner parties. You can also try layering mousse between additional crushed Oreos for a fun twist, making each bite a delightful surprise of textures.
Make Ahead and Storage
Storing Leftovers
Keep any leftover pie covered with plastic wrap or in an airtight container in the refrigerator. It will maintain its freshness and texture for up to 3 days. Avoid leaving it out at room temperature for extended periods to preserve the mousse’s delicate consistency.
Freezing
If you want to enjoy this pie later, it freezes well. Wrap the pie tightly with plastic and then foil to prevent freezer burn. Thaw overnight in the refrigerator before serving to restore its creamy texture perfectly.
Reheating
This dessert is best enjoyed cold, so reheating is not recommended. Instead, let the pie thaw gently to maintain its mousse-like texture, which is the star of this dish.
FAQs
Can I use a different type of cookie crust?
Absolutely! While the Oreo crust adds a perfect chocolate crunch, you can substitute with graham cracker or chocolate wafer crusts to customize the flavor profile.
How do I prevent the mousse from deflating?
Folding the whipped cream gently and avoiding overmixing is key. This helps keep the mousse light and airy with a beautiful fluffy texture.
Can I make this pie dairy-free?
Yes, by using dairy-free chocolate, coconut cream as a substitute for heavy cream, and a suitable dairy-free crust, you can create a vegan-friendly version that’s just as delicious.
Why is it important to chill the pie for 3 hours?
This chilling time allows the mousse to firm up so it holds its shape when sliced, giving you that perfect creamy yet stable pie consistency.
How far in advance can I prepare this pie?
You can make the pie a day ahead, which actually enhances the flavor and texture as the mousse sets fully. Just be sure to keep it well covered in the refrigerator.
