Ingredients

For the Oreo Crust:
– 22 regular Oreo cookies (not Double Stuf)
– 5 tablespoons (71g) unsalted butter, melted

For the Chocolate Mousse Layer:
– 8 ounces (226g) unsweetened chocolate, finely chopped (two 4-ounce bars)
– 2 tablespoons (28g) unsalted butter
– 4 large egg whites (120g)
– 1 cup (200g) granulated sugar
– 1/4 teaspoon cream of tartar
– 2 cups (480mL) heavy cream, cold
– 6 whole Oreos, crushed into crumbs (68g)

For the Whipped Cream Topping:
– 1 cup (240mL) heavy cream, cold
– 2 tablespoons granulated sugar
– 1/2 teaspoon pure vanilla extract
– Optional: chocolate curls or shavings for topping

Making the Crust

Prepare the Crust Mixture

First, preheat your oven to 350°F (177°C). In a food processor, pulse 22 Oreos until they turn into fine crumbs. Then, combine the crumbs with melted butter in a bowl, mixing until evenly coated.

Form the Crust

Next, pour this mixture into an ungreased 9-inch pie dish. Press it firmly to create a thick, compact crust along the bottom and up the sides. Bake this crust for 10 minutes, then let it cool completely on a wire rack. This step is crucial, as a proper cooling will help the crust maintain its shape when we add the delicious filling.

Making the Chocolate Mousse Layer

Melt the Chocolate

Now it’s time to make the mousse layer! In a large heat-proof bowl, microwave the chopped chocolate and butter together. Do this in 20-second intervals, stirring until everything is melted. Allow this mixture to cool slightly while you prepare the meringue.

Create the Meringue

In another heat-proof bowl, combine egg whites, sugar, and cream of tartar. Place this bowl over a pot of simmering water. Whisk constantly until the mixture reaches 160°F (71°C). This ensures that the sugar dissolves thoroughly, creating a stable meringue.

Whip the Meringue

Once the meringue is ready, transfer it to a stand mixer. Beat it on high until soft, glossy peaks form, which should take about 5 to 6 minutes. Gently fold the melted chocolate into the meringue, making sure not to deflate it as you mix.

Fold in the Whipped Cream

Next, whip 2 cups of cold heavy cream to medium-to-stiff peaks. Carefully fold this whipped cream into the chocolate mixture, ensuring it stays light and airy. This is where the magic happens, creating that dreamy mousse texture we’re all after!

Assembling the Pie

Layer the Mousse in the Crust

Now for the fun part—layering! Spread half of the mousse into the cooled Oreo crust. Then, sprinkle it with the crushed Oreo crumbs for added crunch. Top it off with the remaining mousse, creating a lovely dome shape.

Prepare the Whipped Cream Topping

In a clean bowl, whip 1 cup heavy cream, sugar, and vanilla until medium peaks form. Spread this whipped cream over the mousse layer, creating a beautiful topping.

Chill the Pie

Cover the pie with plastic wrap and refrigerate it uncovered for at least 4 hours or up to 1 day. Allow it to come to room temperature for 10 minutes before slicing. Patience is key here, but trust me, it’s worth the wait!

Serving Suggestions

When serving this Sky High Chocolate Mousse Pie, sprinkle some chocolate curls or shavings on top for that extra touch. A dollop of whipped cream also adds to the presentation. This pie is perfect for gatherings or as a delightful after-dinner treat, sure to leave everyone smiling.

Tips for Success

Make sure all your ingredients, especially the heavy cream, are chilled for the best results when whipping.
Be gentle when folding in the whipped cream; this helps preserve the light, airy texture of your mousse.
For the best flavor and texture in the meringue, always use fresh eggs.

Variations

For a minty twist, add a few drops of peppermint extract to the chocolate mixture. It adds a refreshing flavor that pairs wonderfully with chocolate.
If you need a gluten-free option, substitute the Oreo crust with a gluten-free cookie option. It works just as well!

FAQs

1. Can I make this pie in advance?
Yes, making this pie a day ahead is a great idea! Just keep it refrigerated until you’re ready to serve.

2. Can I use a different cookie for the crust?
Absolutely! Any chocolate sandwich cookie will work wonders for the crust.

3. How long does leftover pie last in the fridge?
Leftover pie can be stored for up to 4 days in the refrigerator, covered with plastic wrap or a lid.

4. Can I freeze the pie?
You can freeze it, but the whipped cream might change texture once thawed. Keep that in mind!

5. What can I substitute for heavy cream?
Coconut cream or a dairy-free whipped topping is great for a non-dairy version, although the flavor will be different.

This Sky High Chocolate Mousse Pie will surely bring smiles to the faces of your friends and family. With its rich flavors and fluffy texture, it’s perfect for any celebration or just because. So why not give it a try? Treat yourself to this delicious dessert that’s guaranteed to impress!
