This No-Bake Oreo Mousse Cake has layers of Oreo cookies that are soaked in coffee and layers of a decadent Oreo mascarpone mousse.
Prepare a 9-inch springform pan by lining the bottom with parchment paper and line the sides with either parchment paper or a cake collar. Set aside.
Prepare the mousse: Place your mixing bowl in the freezer or refrigerator for 5-10 minutes before starting.
Grind 10 Oreos into a fine crumb using a food processor or blender. Set aside.
Spoon the mascarpone cream into your bowl and beat on a medium-low speed while slowly pouring in the heavy cream, allowing the mascarpone cheese to turn to a liquid consistency, then add the remaining heavy cream.
Once all the cream has been added, increase the mixing speed to high (speed 8-10) and beat it until soft peaks form.
Next add the vanilla extract, powdered sugar and Oreo crumbs. Beat until well combined, and mixture reaches stiff peaks.
Divide the mousse between two large piping bags. Cut the tip of the piping bags off, about ¾” up from the bottom.
In a small bowl, combine the coffee and milk, stir to combine.
