8 oz cream cheese, softened – Adds richness and creaminess to the mousse.

How to Make No-Bake Oreo Mousse Cake

Let’s get started on this delightful dessert! Follow these simple steps:

In a food processor, crush the 24 Oreo cookies until they are fine crumbs.
In a medium bowl, combine the crushed Oreo cookies and melted butter. Mix until well combined.
Press the Oreo mixture firmly into the bottom of a 9-inch springform pan to form the crust. Set aside.
In a large mixing bowl, beat the cream cheese until smooth. Gradually add the powdered sugar and vanilla extract, mixing until well combined.
In another bowl, whip the heavy cream until stiff peaks form.
Gently fold the whipped cream into the cream cheese mixture until fully incorporated.
Fold in the crushed Oreo cookies.
Pour the mousse filling over the prepared crust in the springform pan, smoothing the top with a spatula.
Refrigerate for at least 4 hours or until set.
Before serving, garnish with additional Oreo cookies as desired. Remove from the springform pan and slice to serve.

Substitutions & Additions

For a gluten-free version, use gluten-free Oreo cookies.
Add a layer of chocolate ganache on top for an extra indulgent treat.
Mix in some mini chocolate chips for added texture.
Try using flavored whipped cream, like peppermint or mocha, for a fun twist!

Tips for Success

Make sure your cream cheese is at room temperature to avoid lumps in your filling.
Don’t skip the refrigeration time; it’s crucial for the mousse to set properly.
Prep the cake a day ahead for best results, giving it ample time to chill.
