Instructions

Make the Crust

1. Preheat the oven to 325°F (163°C).
2. Crush the Oreos into fine crumbs using a food processor or by placing them in a ziplock bag and crushing with a rolling pin.
3. Combine the crumbs with melted butter and mix until evenly moistened. Press the mixture firmly into a 9-inch pie dish.
4. Bake the crust for 12-15 minutes, then let it cool while preparing the brownie layer.

Brownie Layer

5. Melt the bittersweet chocolate, butter, oil, and cocoa powder in the microwave in 20-second intervals, stirring after each until smooth.
6. Whisk in the brown sugar, eggs, vanilla, and salt until fully combined.
7. Stir in the flour, then pour the batter into the prepared crust.
8. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Let the pie cool completely.

Cookie Topping

9. Roughly crush the Oreos using a rolling pin or your hands.
10. Mix the crushed cookies with powdered sugar, cocoa powder, and a pinch of salt.
11. Drizzle melted butter over the mixture and toss to combine. Spread the cookie pieces on a parchment-lined baking sheet and bake for 10 minutes. Let them cool completely.

Mousse Layer

12. Melt the milk chocolate in the microwave using 20-second bursts, stirring between each. Let it cool to 90–100°F.
13. Whip the cream, cocoa powder, powdered sugar, and salt together until soft peaks form.
14. Stir ⅓ of the whipped cream into the cooled chocolate, then gently fold in the remaining whipped cream until smooth.
15. Spread the mousse over the cooled brownie layer. Refrigerate for at least 3 hours or overnight to set.

Chocolate Whipped Cream

16. Beat the heavy cream, granulated sugar, and cocoa powder together until stiff peaks form.
17. Spread the whipped cream over the chilled pie and top with the baked cookie pieces.
