Instead of refrigerating dessert for 3 hours, freeze it for just 1 hour or until firm before cutting into squares.
Garnish each square with a dollop of additional thawed COOL WHIP Whipped Topping and a NILLA Wafer.
No-Mess Crumb Crust
Place 40 wafers in large resealable plastic bag. Use a rolling pin to crush the wafers in the bag. Add sugar and margarine; press down bag to remove excess air, then seal bag. Squeeze bag until mixture is well blended. Empty contents of bag into pan. Use back of spoon or small measuring cup to press crumb mixture onto bottom of pan.
