Use about 8 inch square pan. Line the bottom with whole graham crackers. Make filling of the pudding(milk has already been added just fold in cool whip) and cool whip. Spread half filling on crackers and then add another layer crackers, pudding, another layer of crackers, then pour 1 can cherry pie filling on top of last layer of crackers. Chill for at least 3 hrs., this recipe is better made 1 or 2 days before hand! I double the recipe for large crowds!
