Ingredients

To create this delectable pie, you’ll need the following ingredients:

25 regular Oreos
4 tablespoons (57 grams) salted butter, melted (European style preferred)
4 egg yolks
1/4 cup (50 grams) granulated sugar
1/4 teaspoon fine sea salt
2 cups (480 grams) heavy whipping cream, divided
3/4 teaspoon vanilla extract
8 oz semi-sweet or dark chocolate, chopped
½ cup (120 grams) heavy whipping cream
4 oz semi-sweet or dark chocolate, chopped
½ cup (120 grams) cold heavy whipping cream
1-2 tablespoons powdered sugar

Making the Oreo Crust

Create the Crust Mixture

First things first, preheat your oven to 350°F. Now, take an 8 or 9-inch springform pan and line its bottom with parchment paper. Grab your food processor and pulse those 25 Oreos until they turn into fine crumbs. Next, mix in the 4 tablespoons of melted butter, ensuring everything is evenly combined.

Form the Crust

Press the Oreo mixture firmly into the bottom and slightly up the sides of the pan. Use the back of a measuring cup to smooth it out evenly. Place it in the oven to pre-bake for about 10 to 12 minutes. You’ll know it’s ready when it’s set and aromatic. Allow it to cool for 10 minutes at room temperature, then pop it in the freezer to cool completely.

Preparing the Chocolate Mousse

Whisk the Egg Mixture

Now let’s get to the good stuff—the chocolate mousse! In a heatproof bowl, whisk together 4 egg yolks, 1/4 cup granulated sugar, and 1/4 teaspoon fine sea salt until smooth. Set your bowl over a saucepan filled with simmering water, making sure the bottom doesn’t touch the water. Whisk continuously until the mixture reaches about 160°F, which should take around 4 minutes.

Combine Warm Cream and Chocolate

While you’re waiting, microwave 3/4 cup of heavy cream for about 45 seconds until it’s lukewarm. Gradually whisk that into the egg mixture. Add in 3/4 teaspoon of vanilla extract and set the bowl aside while you focus on the chocolate.

Melt the Chocolate

Grab another bowl and melt 8 oz of chopped chocolate in the microwave, doing it in 30-second increments until smooth. Once it’s melted, fold the chocolate into the egg and cream mixture. Make sure it’s well combined for that rich flavor you’re after.

Fold in Whipped Cream

Now for the magic touch. Take the remaining 1 1/4 cups (300 grams) of heavy cream from the fridge and whip it until medium peaks form. This lightens up the chocolate mixture, making it airy. Gently fold the chocolate mixture into the whipped cream. You want to be careful not to over-mix, as we need to maintain that lovely light texture.

Assemble the Mousse Filling

Once combined, pour the chocolate mousse filling on top of your cooled Oreo crust. Place it in the fridge and let it chill for at least 4 hours, or even better, overnight until it sets perfectly.

Making Chocolate Ganache and Whipped Cream

Prepare the Ganache

Once the mousse has set, it’s time to add that decadent ganache layer. Start by finely chopping 4 oz of chocolate. Heat ½ cup of heavy cream in the microwave for about 30 to 60 seconds until it’s hot. Pour the hot cream over the chopped chocolate and let it sit for 5 minutes. Then, stir it gently until it becomes smooth.

Add the Ganache Layer

Now pour the ganache over the chocolate mousse layer and spread it evenly. Chill the pie for about an hour. Once set, carefully remove the pie from the springform pan.

Finish with Whipped Cream

For the final touch, beat the cold heavy cream along with the powdered sugar until stiff peaks form. Spread this fluffy cream on top of the set pie. Chill it again until you’re ready to serve.

Serving Suggestions

Serving slices of this delicious pie can be a fun moment. Consider adding fresh berries or grated chocolate for that extra flair. A dollop of whipped cream not only enhances each bite but makes everything look super appealing.

Tips for Success

Room Temperature Ingredients: Using room temperature ingredients makes everything mix better, ensuring a smooth and creamy texture.
Melted Chocolate: Make sure your chocolate is completely melted; this yields a smoother ganache.
Chill Your Tools: Chilling your mixing bowls and beaters for whipping cream can help achieve the best volume.

Variations

Feel like getting a little creative? Try making a mint chocolate mousse version by adding peppermint extract to the mousse. For a unique twist, swap out Oreos for graham crackers or chocolate wafer cookies, creating different flavor profiles. You could even mix in chocolate chips or nuts into the mousse for added texture and excitement.
