1 pkg. Oreos, crumbled
1/2 gal. vanilla ice cream, softened
1 jar hot fudge topping, heated
1 (8 oz.) carton Cool Whip

Crumble crackers. Save some for top. Put in bottom of 9 x 13 inch pan or dish to make crust. Spread ice cream, then hot fudge topping, then Cool Whip. Sprinkle reserved crumbs on top. Freeze. Take out of freezer to allow enough time to thaw enough to cut before serving.
