Instructions
- Prepare the Crust: Preheat the oven to 325°F (163°C). In a food processor, pulse 16 Oreo cookies into fine crumbs. Add 1 tablespoon granulated sugar and 4 tablespoons melted butter; pulse until combined. Press the mixture firmly into the bottom and up the sides of a 9-inch pie plate. Bake for 15 minutes until fragrant. Cool on a wire rack.
- Prepare the Brownie Layer: In a microwave-safe bowl, combine 4 ounces chopped bittersweet chocolate, 3 tablespoons unsalted butter, 3 tablespoons vegetable oil, and 1 ½ tablespoons cocoa powder. Microwave at 50% power, stirring frequently, until melted and smooth (about 1 minute 30 seconds). In another bowl, whisk together ⅔ cup dark brown sugar, 2 large eggs, 2 teaspoons vanilla extract, and ¼ teaspoon salt until smooth. Add the melted chocolate mixture and whisk until combined. Stir in 3 tablespoons all-purpose flour until just incorporated. Pour the brownie batter into the cooled Oreo crust. Bake at 325°F (163°C) for about 15 minutes, until the edges are set and a toothpick inserted into the center comes out with a thin coating of batter. Cool on a wire rack for 1 hour, then refrigerate for at least 1 hour until completely chilled.
- Prepare the Topping: In a food processor, pulse 6 Oreo cookies into coarse crumbs. Add 2 tablespoons powdered sugar, 1 tablespoon cocoa powder, and ⅛ teaspoon salt; pulse to combine. Drizzle in 2 tablespoons melted butter and pulse until the mixture resembles wet sand. Spread the crumb mixture evenly on a baking sheet. Bake at 325°F (163°C) for about 10 minutes until fragrant. Cool completely.
- Prepare the Mousse: Melt 6 ounces milk chocolate in a microwave-safe bowl at 50% power, stirring frequently, until smooth. Let cool until the chocolate reaches 85°F (29°C). In a chilled mixing bowl, whisk ½ cup heavy cream until soft peaks form; refrigerate. In another bowl, whisk the remaining ½ cup heavy cream, 2 tablespoons cocoa powder, 2 tablespoons powdered sugar, and a pinch of salt until thickened. Fold the cocoa mixture into the melted chocolate until combined. Gently fold in the whipped cream until no streaks remain. Spread the chocolate mousse evenly over the chilled brownie layer. Sprinkle the cooled cookie crumble topping over the mousse layer. Refrigerate the pie for at least 4 hours until set.
Notes
- Use room temperature eggs for the brownie layer to ensure even mixing and proper texture.
- Make sure the heavy cream is very cold before whipping for best results.
- The mousse should be spread gently to maintain its light and airy texture.
- Allow adequate chilling time for proper set and flavor development.
- Store the pie refrigerated and consume within 3 days for optimal freshness.
