Crust: Mix all ingredients until well blended. Press 2-1/3 cups (14 oz.) of the crumb mixture firmly onto bottom of each of 3 (10-inch) springform pans. Bake in 350°F-standard oven 10 min. Cool completely.
Filling: Combine ice cream, marshmallows and OREO Pieces. Spoon about 2-1/4 qt. of the ice cream mixture over each crust. Freeze at least 4 hours or overnight until firm. Cut each ice cream cake into 12 slices.
For each serving: Spoon 2 Tbsp. of the whipped topping onto each serving; top with 2 tsp. of the peanuts and 1 tsp. of the chocolate curls.
