- Salted butter, 2 Tbsp diced: Adds a subtle richness and helps melt the chocolate evenly.
- Semi-sweet chocolate chips, 1 cup: Provides balanced sweetness and melts smoothly into the mousse.

- Mini marshmallows, 2 cups: Their sweetness and texture create a light, airy mousse base.
- Whole milk, 1/3 cup: Enhances creaminess and blends the ingredients perfectly.

- Oreo pie crust, 1 pre-made crust: The crunchy and slightly salty foundation that complements the sweet mousse.

How to Make Chocolate Mousse Pie with Oreo Crust and Chocolate Shavings Recipe
Step 1: Melt and Combine the Base Ingredients
Start by gently melting the diced salted butter, whole milk, semi-sweet and bittersweet chocolate chips, and mini marshmallows in a large saucepan over low heat. Stir continuously to ensure everything melts evenly and forms a smooth, creamy mixture. This slow melt is essential to avoid burning the chocolate and to let the marshmallows dissolve fully, bringing the mousse its characteristic lightness and silkiness. Once smooth, remove from heat, stir in vanilla extract, and let it cool at room temperature for about an hour.
Step 2: Whip the Heavy Cream
In a large mixing bowl, whip the 1 3/4 cups of heavy whipping cream using an electric mixer until stiff peaks form. This step is crucial because the whipped cream introduces the airy texture that makes this mousse so special. Make sure not to overwhip—the goal is a fluffy, smooth cream that will fold beautifully into the chocolate mixture.
Step 3: Fold the Whipped Cream into the Chocolate Mixture
With a gentle hand, fold the whipped cream into the cooled chocolate marshmallow base using a spatula. The key here is to maintain the airy texture, so fold until just combined and light, without overmixing. This creates a fluffy, luscious mousse that holds its shape while still feeling velvety on the palate.
Step 4: Pour the Mousse into the Oreo Pie Crust
Pour the delicate mousse mixture evenly into the Oreo pie crust, smoothing the top with a spatula to create an even layer. The crust adds a wonderful contrast with its crunchy texture and slightly salty flavor, making every bite an exciting experience.
Step 5: Chill the Pie
Place the pie in the refrigerator and chill for at least 3 hours. This chilling time lets the mousse firm up to the perfect sliceable consistency and helps all the flavors meld together beautifully. Trust me, the wait is worth it!
Step 6: Prepare the Whipped Cream Topping
In a clean bowl, whip 1 cup of heavy cream with the granulated sugar until stiff peaks form. This sweetened whipped cream topping will add a light, creamy finish that is simply irresistible when paired with the rich mousse underneath.
Step 7: Garnish and Serve
Spread the whipped cream lovingly over the chilled mousse pie, then sprinkle generously with chocolate shavings. These shavings not only elevate the look of the pie with a hint of rustic elegance but also add extra bursts of chocolate flavor in every bite.
How to Serve Chocolate Mousse Pie with Oreo Crust and Chocolate Shavings Recipe

Garnishes
Chocolate shavings are the star garnish here, bringing a touch of indulgence and visual appeal. For a festive twist, you can add fresh raspberries or a dusting of cocoa powder to contrast the rich chocolate. A sprinkle of crushed Oreos also adds texture and ties the garnish back to the crust.
Side Dishes
This pie is rich and decadent, so pairing it with something light works great. Consider fresh strawberries, a scoop of vanilla ice cream, or a simple fruit salad to balance the richness. A glass of milk or a cup of strong coffee also makes a perfect companion during dessert time.
Creative Ways to Present
Serve individual pie slices with a dollop of whipped cream and a chocolate curl on top for an elegant touch. Alternatively, place smaller mousse servings in clear dessert cups layered with crushed Oreos and whipped cream for a delightful twist on presentation that’s perfect for parties.
Make Ahead and Storage
Storing Leftovers
Leftover pie can be stored covered in the refrigerator for up to 3 days. Make sure to keep it tightly wrapped to maintain freshness and prevent the whipped cream topping from drying out. The flavors actually deepen when chilled, so leftovers taste fantastic!
Freezing
While the pie’s texture is best fresh, you can freeze it for up to one month. Wrap it securely in plastic wrap and then in foil to avoid freezer burn. Thaw overnight in the refrigerator before serving; note the whipped cream topping may lose some fluffiness, so you might want to re-whip fresh cream to reapply just before serving.
Reheating
This dessert is not meant to be heated, as the mousse and whipped cream will lose their airy texture and structure. It’s best enjoyed cold straight from the fridge for that perfect melt-in-your-mouth experience.
FAQs
Can I make the Oreo crust from scratch?
Absolutely! While a pre-made Oreo crust is convenient, you can crush Oreos yourself and mix with melted butter to create a homemade crust that’s equally delicious and fresh.
Is it necessary to use both semi-sweet and bittersweet chocolate chips?
Using both types balances the chocolate flavor perfectly—semi-sweet adds sweetness, while bittersweet gives a deeper chocolate punch. You can adjust the ratio depending on your taste preferences.
Can I use regular marshmallows instead of mini marshmallows?
Yes, but mini marshmallows melt more evenly and quickly, helping to create that perfect mousse texture. If you use regular size, cut them into smaller pieces for best results.
How long does the mousse take to set?
Chilling the mousse for at least 3 hours allows it to set firmly and develop its signature airy texture. Overnight chilling is even better if you have the time!
What can I use instead of chocolate shavings for garnish?
If you don’t have a grater or shavings, finely chopped chocolate pieces, cocoa powder dusting, or even chocolate chips make great alternative garnishes.
