You can make this decadent, creamy chocolate mousse pie without turning on your oven. It features a simple Oreo crust and a light, airy chocolate filling, topped with whipped cream.

Ingredients

Scale
  • 1 3/4 cups Oreo cookie crumbs (about 25 cookies)
  • 6 tablespoons unsalted butter, melted
  • 1 package (8 ounces) cream cheese, softened
  • 1 cup powdered sugar
  • 1 teaspoon vanilla extract
  • 1 cup heavy whipping cream, cold (for filling)
  • 8 ounces semi-sweet chocolate, melted and slightly cooled
  • 1 cup heavy whipping cream, cold (for topping)
  • 2 tablespoons powdered sugar (for topping)
  • 1/2 teaspoon vanilla extract (for topping)

Instructions

  1. Prepare the crust: Combine the Oreo cookie crumbs and melted butter in a medium bowl. Press the mixture firmly and evenly into the bottom and up the sides of a 9-inch pie plate. Place the crust in the freezer while you prepare the filling.
  2. Make the cream cheese base: In a large bowl, beat the softened cream cheese with an electric mixer until smooth. Gradually add 1 cup of powdered sugar and 1 teaspoon of vanilla extract, beating until fully combined and creamy.
  3. Prepare the mousse filling: In a separate, chilled bowl, whip 1 cup of cold heavy whipping cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until just combined.
  4. Add the chocolate: Slowly fold the melted and slightly cooled semi-sweet chocolate into the mousse mixture until no streaks remain. Be careful not to overmix to keep the mousse light.
  5. Assemble the pie: Pour the chocolate mousse filling into the chilled Oreo crust. Smooth the top with a spatula. Cover the pie loosely with plastic wrap and refrigerate for at least 4 hours, or until the filling is firm.
  6. Make the topping: Before serving, whip the remaining 1 cup of cold heavy whipping cream with 2 tablespoons of powdered sugar and 1/2 teaspoon of vanilla extract until stiff peaks form.
  7. Finish and serve: Spread or pipe the whipped cream topping over the chilled pie. You can garnish with chocolate shavings if desired. Slice and serve immediately.

Notes

  • For the best texture, ensure your melted chocolate has cooled slightly before folding it into the mousse base. If it is too hot, it will deflate the whipped cream.
  • You can substitute the Oreo crust with a graham cracker crust if you prefer a different base flavor.
  • This make-ahead chocolate dessert is best served within 2 days of preparation.
