Equipment

Ingredients
  

Oreo Cookie Crust:

  • 18 Oreo cookies
  • 3 Tbsp salted butter melted

Mousse Recipe:

  • ¾ cup heavy whipping cream heated
  • 10 oz semi sweet chocolate about 1 1/2 cups chopped, or chocolate chips
  • 1 ½ cups heavy cream whipped until stiff peaks form
  • 1 tsp vanilla extract
  • pinch salt

Topping:

  • ¾ cup heavy whipping cream
  • 3 Tbsp powdered sugar
  • ½ tsp vanilla extract
  • 6 Oreo cookies cut in half
  • 1.5 oz milk chocolate bar I used part of a Symphony bar.

Instructions
 

  • Cut a circle of parchment paper and place it in the bottom of a 9" springform pan.
  • In a food processor, finely crush the Oreos. Stir together with the melted butter. Press firmly in the bottom of the pan. Place in the refrigerator while you make the filling.
  • Bring the 3/4 cup of cream barely to a simmer in a heavy small saucepan over medium heat. Remove from the heat. Dump in the chopped chocolate. Let sit for 1-2 minutes, then whisk until smooth.
  • Cover chocolate with plastic wrap and chill for 20-25 minutes.
  • In a cold bowl, beat the 1 1/2 cups of heavy cream until stiff peaks form. Add the vanilla and salt. Whisk the chilled chocolate, then add it to the cream. Use a rubber spatula to fold it gently into the whipped cream.
  • Spread the chocolate mousse evenly over the oreo crust. Cover and chill for at least 6 hours.
  • When ready to serve, beat the last 3/4 cup of cream in a cold bowl until stiff peaks form. Beat in the powdered sugar and vanilla.
  • Use a large star tip to pipe the cream around the edges of the cake. Garnish with the halved Oreos and chocolate curls.

Notes

-I find that milk chocolate bars work a little better for making chocolate curls, but you can use dark chocolate if you prefer. You won't need the entire bar.
