Directions

Step 1: Make the Crust

Preheat the oven to 325°F (163°C).
Crush the Oreo cookies into fine crumbs, and mix with the melted butter. Press the mixture into the bottom of a 9-inch pie dish.
Bake for 12-15 minutes, then remove from the oven and set aside to cool.

Step 2: Make the Brownie Base

Melt the butter, chopped chocolate, vegetable oil, and cocoa powder in a microwave-safe bowl. Stir until smooth.
Whisk in the brown sugar, eggs, vanilla extract, and salt.
Stir in the flour until the batter is thick and smooth.
Pour the brownie batter into the prepared Oreo crust and bake for 25-30 minutes. The brownie layer should be set but slightly fudgy in the center.
Allow the pie to cool completely.

Step 3: Make the Mousse Layer

Melt the milk chocolate chips in a microwave-safe bowl, stirring until smooth.
Beat the heavy cream, cocoa powder, powdered sugar, and salt in a separate bowl until soft peaks form.
Gently fold in 1/3 of the whipped cream with the melted chocolate, then fold in the rest of the whipped cream.
Spread the mousse layer over the cooled brownie base and refrigerate for at least 3 hours or overnight.

Step 4: Make the Whipped Cream Topping

Beat the heavy cream, powdered sugar, and vanilla extract until stiff peaks form.
Spread the whipped cream on top of the mousse layer.

Step 5: Make the Oreo Crumble Topping

Crush the Oreo cookies and toss with powdered sugar, cocoa powder, and melted butter.
