15 Oreos (or similar cookies) 3 tbsp melted margarine 2 favorite candy bars (I used Snickers, but they proved difficult to chop with the food processor) 1/2 gallon of any flavor ice cream (I used Blue Bell Chocolate Sundae flavor) 1 12-oz container Cool Whip, thawed Multicolored sprinkles or small candy decorations
On cutting board, chop cookies. With food processor 2-3 at a time. Melt margarine in covered microcooker, mix in cookie crumbs with bamboo spoon. Press crumb mixture in bottom of springform pan; freeze 15 minutes. Cut candy bars into four pieces and chop with food chopper.
Using kitchen shears, cut ice cream container apart. Using garnisher, cut 1/2 of ice cream into 1 inch thick slices. Arrange ice cream slices over cookie crust, cutting pieces to fit. Spread into a smooth layer with all purpose spreader. Sprinkle with chopped candy bar. Top with remaining ice cream prepared the same way as the first layer. Smooth top with spreader. Cover with aluminum foil and freeze 3 hours or overnight.

Freeze one hour or overnight. Once cool whip is frozen, lightly cover cake with plastic wrap.
