Crush ¾ of a box of Biscoff cookies in a food processor or place in a ziploc bag and smash with a rolling pin.
Mix the crumbs with the melted butter and press into the bottom and partially up the sides of a springform pan.
Refrigerate for 30 minutes until it is set.
Filling
Beat the cream cheese, vanilla powdered sugar, and cookie butter until smooth.
Fold in the whipped topping until it is all incorporated.
Pour the filling into the springform pan.
Crush the remaining cookies and sprinkle cookie crumbs over the cheesecake.
Refrigerate the cheesecake for at least 4 hours to give it time to firm up.
Serve!
