1 box whole graham crackers
2 sm. boxes instant vanilla pudding
3 c. cold milk
8 to 9 oz. Cool Whip
1 can chocolate frosting

Grease a 9 x 13 inch pan with butter. Mix pudding with milk; fold in Cool Whip. Put layer of whole crackers on bottom, then layer of pudding mixture. Repeat until you reach top of pan. End layer should be cracker layer. Chill 2 to 3 hours (chill overnight for best cutting results.) Then cover top layer with chocolate frosting. Cut and serve.
