This Oreo Mousse Cake is a decadent no-bake dessert featuring a crunchy Oreo crust, a luscious semi-sweet chocolate mousse layer, and a fluffy whipped cream topping sprinkled with Oreo crumbs. Perfect for chocolate lovers and easy to prepare, it combines creamy textures and rich flavors in a stunning 9-inch springform pan cake.

Ingredients

Scale

Crust

  • 1 package Oreo Cookies (standard, crushed)
  • ⅓ cup unsalted butter (melted)

Mousse

  • 8 oz semi-sweet chocolate chips (melted)
  • 3 cups heavy whipping cream
  • ½ cup confectioner’s sugar

Topping

  • Additional crushed Oreo pieces (for garnish)

Instructions

  1. Prepare the crust: Combine the crushed Oreos and melted unsalted butter in a mixing bowl. Stir until the mixture is well combined and the crumbs are evenly moistened.
  2. Form the crust: Press the Oreo and butter mixture firmly into the bottom of a lined 9-inch springform pan. Place the pan in the freezer to chill while preparing the mousse filling.
  3. Melt the chocolate: In a microwave-safe bowl, melt the semi-sweet chocolate chips in 30-second increments, stirring after each interval until fully melted and smooth. Set aside to cool slightly but do not let it harden.
  4. Whip the cream: Using the whisk attachment of a stand mixer or electric mixer, whip the heavy cream and confectioner’s sugar on medium speed until stiff peaks form. For best results, chill the mixing bowl beforehand.
  5. Combine chocolate and cream: Gently fold half of the whipped cream into the slightly cooled melted chocolate until fully incorporated, creating a smooth chocolate mousse layer.
  6. Assemble the mousse layer: Pour and spread the chocolate mousse evenly over the chilled Oreo crust in the springform pan, smoothing it out to the edges.
  7. Add the remaining whipped cream: Spread the remaining whipped cream uniformly over the chocolate mousse layer to create a contrasting, fluffy topping.
  8. Garnish and chill: Sprinkle additional crushed Oreo pieces on top for decoration. Cover the cake loosely and refrigerate for approximately 4 hours to set before serving.

Notes

  • Chilling the mixing bowl before whipping cream helps achieve stiffer peaks.
  • Use a springform pan for easy removal of the cake.
  • This dessert is best served chilled and consumed within 2-3 days for freshness.
  • Double stuffed Oreos may make the crust too moist; standard Oreos are preferred.
  • For a firmer mousse, you can chill the chocolate mixture before folding in the cream.
