Add the oreos to a food processor and process until you have fine crumbs. Transfer the crumbs to a mixing bowl, then add the melted butter in and mix until the crumbs are moistened.
Scoop the mixture into a 9 inch spring form pan, and firmly press it down into one even layer. Place in freezer to let chill while you make the cheesecake filling.
To make the cheesecake:
In a stand mixer using the whisk attachment, or in a large mixing bowl using a hand held mixer, pour the heavy cream in and beat until stiff peaks for about 5 minutes.
In a separate bowl, your going to beat the cream cheese until smooth. Add in the powdered sugar and vanilla extract and mix until well combined.
Then add the whipped cream in with the cream cheese mixture and gently fold it in. Then fold in the chopped oreos.
Remove the spring form pan from the freezer, scoop the cheesecake filling onto crust and use a spatula to even out the top.
Cover tightly and transfer into the refrigerator to chill for at least 4-5 hours or overnight.
