Ingredients

Scale

Crust

  • 1 package (14.3 ounces) Oreo cookies, crushed (about 2 cups for crust)
  • 1/3 cup butter, melted

Mousse

  • 8 ounces semisweet chocolate, chopped
  • 3 cups heavy whipping cream
  • 1/2 cup confectioners’ sugar

Optional Garnish

  • Additional whole or crushed Oreos

Instructions

  1. Prepare the crust: In a small bowl, combine 2 cups of the crushed Oreo cookies with the melted butter. Mix well until the crumbs are evenly coated. Press this mixture firmly onto the bottom of a greased 9-inch springform pan to form an even crust. Refrigerate the crust until you are ready to use it.
  2. Melt the chocolate: Place the chopped semisweet chocolate in a large microwave-safe bowl. Microwave on high in short bursts, stirring frequently, until the chocolate is just melted and smooth. Allow the melted chocolate to cool to room temperature so it doesn’t melt the whipped cream when combined.
  3. Whip the cream: In a separate mixing bowl, beat the heavy whipping cream with the confectioners’ sugar until stiff peaks form. This means the cream holds its shape firmly when the beaters are lifted.
  4. Make the mousse: Gently fold 4 cups of the whipped cream into the cooled melted chocolate. Be careful not to deflate the cream to maintain a light and airy texture.
  5. Assemble the cake: Spread the chocolate mousse evenly over the prepared Oreo crust in the springform pan. Then, spread the remaining whipped cream over the top layer for a creamy finish.
  6. Chill and set: Cover the assembled cake and refrigerate for about 3 hours, or until firm and set.
  7. Optional garnish: Before serving, garnish the cake with additional whole or crushed Oreos if desired.

Notes

  • Make sure the melted chocolate is completely cooled before folding in the whipped cream to prevent the mousse from becoming runny.
  • Use a springform pan for easy removal of the delicate mousse cake.
  • Crushing Oreos finely will help create a firm and even crust.
  • You can substitute the Oreo crust with gluten-free chocolate sandwich cookies if needed.
  • For best results, chill the cake overnight.
