Spray a 24 count mini muffin pan with cooking spray and set aside.
Take a little more than 1 tablespoon of dough and press into the bottom and up the sides of 18 cavity of the mini muffin pan.
Bake the cookie cups for 10-12 minutes or till they just start to turn golden around the edges.
Remove from the oven, cool and then remove cookie cups carefully from the pan. They should come out easily if not run a butter knife around the edges to release the cookies from the pan.
Make the filling by beating together room temperature cream cheese and unsalted butter on medium speed using your hand/stand mixer till smooth and creamy.
Add vanilla extract and mix till combined.
Add confectioners sugar, little by little beating well after each addition.
Finally add the oreo cookie crumbs, heavy cream and mix for a minute on medium speed till it's all smooth.
Fill the cooled cookie cups with the oreo filling.
