Step-by-Step Instructions
Prepare the Oreo Crust
Preheat your oven to 350°F (175°C).
Using a food processor, pulse the Oreo cookies into fine crumbs.
Combine the crumbs with melted butter in a medium bowl, mixing until evenly moistened.
Press the mixture into a 9-inch pie plate, covering the bottom and sides evenly.
Bake for 10 minutes, then set aside to cool completely.
Make the Brownie Layer
In a heatproof bowl over simmering water, melt the butter and bittersweet chocolate together, stirring until smooth.
Remove from heat and whisk in vegetable oil and cocoa powder until combined.
Add the sugars and mix thoroughly.
Whisk in the eggs, one at a time, ensuring each is fully incorporated. Stir in vanilla extract and salt.
Gently fold in the flour until just combined.
Pour the batter into the cooled crust, smoothing the top.
Bake for 35–40 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Let cool completely.
Create the Chocolate Mousse Layer
Melt the milk chocolate with ½ cup of heavy cream in a heatproof bowl over simmering water, stirring until smooth.
Allow the mixture to cool to about 80°F (27°C) to prevent deflating the mousse.
In a separate bowl, whip the remaining 1 cup of heavy cream with a pinch of salt, vanilla extract, and sifted powdered sugar until soft peaks form.
Gently fold the cooled chocolate mixture into the whipped cream until fully incorporated.
Spread the mousse evenly over the brownie layer. Refrigerate for at least 4 hours, or until set.
Add the Finishing Touches
Before serving, garnish the pie with crushed Oreo cookies and optional chocolate shavings or curls.
Slice and serve chilled for the ultimate chocolate experience.
