Pour fudge topping into medium bowl. Add 1 cup of the whipped topping; stir with wire whisk until well blended. Add dry pudding mix; stir 2 min. or until well blended. Gently stir in chopped cookies; set aside.
Arrange 4 of the ice cream sandwiches, side-by-side, on 24-inch-long piece of foil; top with half of the whipped topping mixture. Repeat layers. Top with remaining 4 ice cream sandwiches. Frost top and sides of dessert with remaining whipped topping. Bring up foil sides. Double fold top and ends to loosely seal packet.
Freeze at least 4 hours before serving. Store leftover dessert in freezer.
Instead of using only Vanilla, I chose both Vanilly and Neopolitan Ice Cream Sandwiches. You can also save oreos for decoration or like I did, use Fudge for decoration and put oreos on the sides of the cake for extra decoration. Here's the cake before we ate it. It was pretty good. I think it could have used more ice cream. But that's only because I LLLLLLOOOOOOOOOVVVVVVEEEE ice cream.
