For The Cake Base:

  • Oreo biscuits: 10 pcs
  • Unsalted melted butter: 3 tablespoons (42 g)

For The Mousse:

  • Semi-sweet dark chocolate: 200 g (7 ounces)
  • Whipping cream: 1/3 cup (80 ml)
  • Whipping cream: 1 1/3 cups (320 ml)

For The Chocolate Mixture:

  • Hot whipping cream: 1/3 cup (80 ml)
  • Semi-sweet dark chocolate: 100 g (3.5 ounces)


Step 1: Preparing the Cake Base

  1. Grinding the Biscuits: Finely grind 10 Oreo biscuits in a food processor or crush them in a Ziploc bag using a rolling pin.
  2. Mixing with Butter: Transfer the ground biscuits to a bowl. Add 3 tablespoons of unsalted melted butter and mix well until combined.
  3. Forming the Base: Press the mixture into the bottom of a 4-inch cake mold, creating an even layer. Refrigerate the base while you prepare the mousse.

Step 2: Making the Chocolate Mousse

  1. Melting the Chocolate: Combine 200 g of semi-sweet dark chocolate and 1/3 cup of whipping cream in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until the chocolate is melted and smooth. Let it cool to room temperature.
  2. Whipping the Cream: In a separate bowl, beat 1 1/3 cups of whipping cream until stiff peaks form.
  3. Combining Chocolate and Cream: Mix a small portion of the whipped cream into the melted chocolate to lighten it. Then, gently fold the chocolate mixture into the remaining whipped cream until well combined and smooth.
  4. Layering the Mousse: Spread the chocolate mousse evenly over the prepared Oreo base in the cake mold, smoothing the top with a spatula.

Step 3: Setting the Mousse

  1. Freezing: Place the cake mold in the freezer for two to four hours, or until the mousse is fully set.

Step 4: Preparing the Chocolate Ganache

  1. Heating the Cream: In a saucepan, heat 1/3 cup of whipping cream until it begins to simmer.
  2. Melting the Chocolate: Place 100 g of semi-sweet dark chocolate in a bowl. Pour the hot cream over the chocolate and let it sit for 1-2 minutes to melt. Stir until smooth and glossy.

Step 5: Finishing the Cake

  1. Unmolding the Cake: Once the mousse is set, carefully remove the cake from the mold.
  2. Adding the Ganache: Pour the chocolate ganache over the top of the mousse cake, spreading it evenly with a spatula. For an extra touch, sprinkle some shredded chocolate on top if desired.

Step 6: Serving

  1. Chilling: Allow the cake to sit in the refrigerator for about 30 minutes to let the ganache set.
  2. Serving: Slice and serve this decadent no-bake Oreo chocolate mousse cake to your guests. Enjoy the rich, creamy layers and the delightful crunch of the Oreo base.
