I got this recipe from kraftfoods.com. It was so easy to make that KT did it mostly all by herself. It was a BIG hit, especially with the kids.
OREO & FUDGE ICE CREAM CAKE:
1/2 cup hot fudge ice cream topping, warmed
1 tub (8 oz.) Cool Whip, thawed, divided
1 pkg. (4-serving size) Jell-O Chocolate Flavor Instant Pudding & Pie Filling
8 Oreo Chocolate Sandwich Cookies, chopped (about 1 cup) **I crushed ours**
12 vanilla ice cream sandwiches, unwrapped
Pour fudge topping into medium bowl. Add 1 cup of the Cool Whip; stir with wire whisk until well blended. Add dry pudding mix; stir 2 minutes 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 Cool Whip mixture. Repeat layers. Top with remaining 4 ice cream sandwiches. Frost top and sides of dessert with remaining plain Cool Whip. Bring up foil sides. Double fold top and ends to loosely seal packet.
Freeze at least 4 hours before serving. Store leftovers in freezer.
