Ingredients

Scale

Crust

  • 25 Oreo cookies
  • 6 tablespoons salted butter, melted

Brownie Layer

  • 4 ounces bittersweet chocolate, chopped
  • 3 tablespoons salted butter, melted
  • 3 tablespoons vegetable oil
  • 2 tablespoons unsweetened cocoa powder
  • 2/3 cup light brown sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1/4 teaspoon salt
  • 3 tablespoons all-purpose flour

Cookie Topping

  • 8 Oreo cookies
  • 2 tablespoons powdered sugar
  • 1 tablespoon dutch-processed cocoa powder
  • Pinch of salt
  • 2 tablespoons salted butter, melted

Mousse Layer

  • 6 ounces milk chocolate, chopped
  • 1 cup cold heavy cream
  • 2 tablespoons dutch-processed cocoa powder
  • 2 tablespoons powdered sugar
  • Pinch of salt

Chocolate Whipped Cream

  • 1 cup heavy cream
  • 1/4 cup granulated sugar
  • 3 tablespoons unsweetened cocoa powder

Instructions

  1. Prepare Crust: Preheat the oven to 325°F. Finely crush 25 Oreo cookies in a food processor or by pounding them in a ziplock bag until they become fine crumbs. Mix the crumbs with 6 tablespoons of melted salted butter until evenly moistened. Press this mixture firmly into a 9-inch pie plate to form the crust. Bake for 12-15 minutes until the crust is set.
  2. Make Brownie Layer: In a microwave-safe bowl, heat 4 ounces chopped bittersweet chocolate, 3 tablespoons melted salted butter, 3 tablespoons vegetable oil, and 2 tablespoons unsweetened cocoa powder in 20-second intervals, stirring after each. When fully melted and combined, whisk in 2/3 cup light brown sugar, 2 large eggs, 2 teaspoons vanilla extract, and 1/4 teaspoon salt until smooth. Stir in 3 tablespoons all-purpose flour just until combined. Pour the batter over the baked Oreo crust.
  3. Bake Brownie Layer: Bake the pie for 25-30 minutes until a toothpick inserted into the brownie layer comes out barely wet with a little batter. Alternatively, use an instant digital thermometer; the internal temperature should reach 180°F for a fudgy set. Remove from oven and let cool.
  4. Prepare Cookie Topping: Crush 8 Oreo cookies roughly by placing them in a ziplock bag and lightly pounding with a rolling pin. Combine crushed cookies with 2 tablespoons powdered sugar, 1 tablespoon dutch-processed cocoa powder, and a pinch of salt. Drizzle 2 tablespoons melted salted butter over the cookie mixture and toss well to moisten evenly. Spread the mixture onto a parchment-lined baking sheet and bake for 10 minutes. Allow to cool completely before using.
  5. Make Chocolate Mousse Layer: Melt 6 ounces chopped milk chocolate in 20-second bursts in the microwave, stirring between intervals until smooth. Let the chocolate cool for about 10 minutes until it reaches 90-100°F. Meanwhile, in a stand mixer or with an electric mixer, beat 1 cup cold heavy cream with 2 tablespoons powdered sugar, 2 tablespoons dutch-processed cocoa powder, and a pinch of salt until soft peaks form. Stir one-third of the whipped cream into the cooled chocolate, then fold in the remaining whipped cream gently with a rubber spatula until homogenous. Spread this mousse layer evenly over the cooled brownie layer.
  6. Chill Pie: Refrigerate the pie for at least 3 hours, or overnight, to set properly.
  7. Prepare Chocolate Whipped Cream: In a clean bowl, beat 1 cup heavy cream with 1/4 cup granulated sugar and 3 tablespoons unsweetened cocoa powder until stiff peaks form. Spread this whipped cream over the chilled pie evenly.
  8. Finish and Serve: Sprinkle the cooled baked cookie topping over the whipped cream layer just before serving for added crunch and chocolate flavor contrast.

Notes

  • Make sure the chocolate for the mousse cools adequately before folding in whipped cream to prevent melting or deflating.
  • A toothpick test helps ensure the brownie layer is fudgy and not overbaked.
  • Chilling the pie overnight improves the texture and flavor melding.
  • For best results, use fresh and high-quality chocolate.
  • This pie is rich and best served in small slices.
