Preheat the oven to 350°F. Lightly grease a 9-inch springform pan. Set the cream cheese out to soften.
Layer the presliced cookies into the bottom of the springform pan. It's ok if they aren't touching. They will touch as they bake.

Bake for 15-18 minutes, until lightly golden at the edges and set in the center. Cool completely. Set aside.
On a separate baking sheet, bake the second package of cookie dough according to the package directions. Cool completely and set aside.
In a large bowl, beat the cream cheese until completely smooth.
Beat in the powdered sugar until combined.
Mix in the vanilla extract.
Beat in the sour cream until smooth.
Gently fold in the whipped topping until fully combined.
Stir in the Halloween sprinkles.
Spread half the cheesecake filling over the cooled crust.
Place about 10 cookies flat on top of the cheesecake filling, reserving 8 more baked cookies for garnish.
Spread the remaining cheesecake filling over the cookie layer and smooth the top.
Cover and refrigerate at least 6 hours, preferably overnight. The crust and middle cookie layer will soften.
Once fully chilled: Dip a knife into warm water and slowly run it around the springform pan to help release the cheesecake. Unclip the latch and gently remove the ring. I prefer to leave the base under the cheesecake or you can use a large spatula to transfer the whole cheesecake to a cake platter or plate.
Before serving, top with whipped cream, the baked cookies, and more sprinkles. Slice and serve chilled.
