Jimmy Fallon's Late Night Snack Ice Cream Cake

Wrap the bottom of a 9-inch round springform pan with two layers of plastic wrap.

Remove ice cream pieces from container; discard container. Place ice cream pieces on top of cookies in pan. Place a large piece of plastic wrap over ice cream and gently press to fit into pan; remove plastic and spread with an offset spatula to make even. Drizzle with caramel sauce and top with 6 more wafer cookies; transfer to freezer and freeze until firm, about 2 hours.
