Make the cheesecake filling . In a separate bowl, beat the cream cheese using the paddle attachment until soft and fluffy, or about 2 minutes. Add the powdered sugar and vanilla extract to the cream cheese and mix on low until incorporated. Increase the speed to high and beat until fluffy.
Lightly spray a 9x9" pan with non-stick baking spray. Set aside. In a food processor, crush the chocolate cookies. Add the melted butter, and pulse a few more times in the processor to combine. Pour the crumb mixture into the 9x9 pan, and press firmly and evenly into the bottom of the pan.
