4.7 from 145 reviews

This Oreo Mousse Cake is a decadent no-bake dessert featuring a crunchy Oreo cookie crust layered with rich semi-sweet chocolate mousse and topped with fluffy whipped cream and crushed Oreo pieces. Perfect for any Oreo lover seeking an indulgent yet easy-to-make treat.

Ingredients

Scale

Crust

  • 14.3 oz Oreo Cookies (crushed, standard Oreos, not double stuffed)
  • ⅓ cup unsalted butter (melted)

Mousse

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

Instructions

  1. Prepare the crust: Combine the crushed Oreo cookies and melted butter in a mixing bowl. Mix thoroughly until the crumbs are evenly moistened by the butter.
  2. Form the crust: Press the Oreo mixture firmly and evenly into the bottom of a lined 9-inch springform pan. Place the pan in the freezer to chill and set until ready to add filling.
  3. Melt the chocolate: Place the semi-sweet chocolate chips in a microwave-safe bowl. Heat in 30-second increments, stirring after each session until the chocolate is fully melted and smooth. Set aside to cool slightly but do not allow it to harden.
  4. Whip the cream: In a chilled bowl attached to a stand mixer with the whisk attachment, whip the heavy cream and confectioner’s sugar on medium speed until stiff peaks form. This ensures a light and airy mousse texture.
  5. Combine chocolate and cream: Gently fold half of the whipped cream into the cooled melted chocolate. Use a spatula or spoon to fold carefully to maintain airiness, mixing until evenly combined.
  6. Assemble mousse layer: Pour and spread the chocolate mousse mixture evenly over the chilled Oreo crust in the springform pan, reaching the edges.
  7. Add whipped topping: Evenly spread the remaining whipped cream over the chocolate mousse layer to create a smooth, fluffy top.
  8. Garnish: Sprinkle additional crushed Oreo cookie pieces over the whipped cream layer for extra texture and visual appeal.
  9. Chill: Cover the cake loosely and refrigerate for approximately 4 hours to allow the mousse to set completely before serving.

Notes

  • For best results, chill the mixing bowl and whisk attachment before whipping the cream to help it whip faster and achieve maximum volume.
  • Ensure the melted chocolate is cooled but still pourable before folding in the whipped cream to prevent melting the cream.
  • You can substitute semi-sweet chocolate chips with dark or milk chocolate chips depending on your preference.
  • This cake is best served chilled and should be stored in the refrigerator.
  • Press the crust firmly to avoid a crumbly base when slicing.
