Ingredients

Scale

Crust

  • 16 Oreo cookies
  • 1 tablespoon sugar
  • 4 tablespoons unsalted butter, melted and cooled

Brownie Layer

  • 4 ounces bittersweet chocolate, finely chopped
  • 3 tablespoons unsalted butter
  • 3 tablespoons vegetable oil
  • 1 1/2 tablespoons cocoa powder
  • 2/3 cup dark brown sugar, firmly packed
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1/4 teaspoon salt
  • 3 tablespoons all-purpose flour

Topping

  • 6 Oreo cookies
  • 2 tablespoons powdered sugar
  • 1 tablespoon cocoa powder
  • 1/8 teaspoon salt
  • 2 tablespoons unsalted butter, melted

Mousse

  • 6 ounces milk chocolate, chopped fine
  • 1 cup heavy cream, very cold (divided)
  • 2 tablespoons cocoa powder
  • 2 tablespoons powdered sugar
  • Pinch of salt

Instructions

  1. Make Crust: Place an oven rack in the center position and preheat the oven to 325°F (163°C). Pulse the 16 Oreos in a food processor until fine crumbs form. Pour melted and cooled butter over the crumbs and pulse until combined. Press this mixture firmly into the bottom and up the sides of a 9-inch pie plate. Bake for about 15 minutes until fragrant, then cool on a wire rack.
  2. Make Brownie Layer: In a microwave-safe bowl, combine chopped bittersweet chocolate, butter, vegetable oil, and cocoa powder. Microwave at 50% power, stirring frequently until melted (around 1 minute 30 seconds). In another bowl, whisk dark brown sugar, eggs, vanilla extract, and salt until smooth. Incorporate the warm chocolate mixture, then fold in the flour just until combined. Pour the batter over the prepared Oreo crust and bake in the center of the oven for about 15 minutes or until edges are set and a toothpick comes out with a thin coating. Cool on a wire rack for 60 minutes, then refrigerate fully for at least 60 minutes.
  3. Make the Topping: Line a baking sheet with parchment paper. Crush 6 Oreos into 1/2 to 3/4 inch pieces using a rolling pin inside a resealable bag. In a bowl, combine crushed Oreos, powdered sugar, cocoa powder, salt, and melted butter; mix until moistened and clumps form. Spread evenly on the baking sheet and bake for about 10 minutes until fragrant, stirring halfway through. Cool completely on a wire rack and break up any large clumps.
  4. Make the Mousse: Melt the milk chocolate in a microwave-safe bowl at 50% power, stirring frequently until smooth (about 1 1/2 to 2 minutes). Let cool until warm (90-100°F or 32-38°C). Heat 3 tablespoons of heavy cream to 105-110°F (40-43°C), then whisk in cocoa powder until smooth. Combine this with powdered sugar, a pinch of salt, and the remaining heavy cream in a stand mixer bowl. Whip on medium until thickened, then on high until soft peaks form (2-3 minutes). Fold a third of the whipped cream into the warm chocolate, then fold in the rest gently. Spread the mousse evenly over the cooled pie.
  5. Assemble and Chill: Sprinkle the cooled topping crumbs evenly over the mousse layer. Refrigerate the pie for 3-4 hours or preferably overnight to set before serving.

Notes

  • Make sure the crust is completely cool before adding the brownie layer to prevent sogginess.
  • Allow the melted chocolate to cool to the correct temperature before folding in the whipped cream to ensure a smooth mousse texture.
  • Use a sharp knife to chop chocolates finely for easier melting and smoother batter.
  • The pie is best when chilled overnight to develop flavors and firm up the mousse.
  • For a firmer mousse, chill bowl and whisk before whipping cream.
