1 (16 ounce) package chocolate sandwich cookies (such as Oreo®), crushed into chunks
Instructions
Combine cream cheese, powdered sugar, and butter in a large bowl; beat with an electric mixer until creamy. Add milk and vanilla pudding mix and beat until well combined and all lumps are gone. Fold in whipped topping.
Distribute 1/2 of the chocolate sandwich cookies on the bottom of a 9x13-inch dish. Cover with the pudding mixture and top with remaining cookie chunks. Cover and refrigerate for 8 hours to overnight.
