To prepare puddings, place both of the puddings in a mixing bowl, add milk and whipped cream. Mix well and set aside. Cut the bananas on an angle into thin slices.
Take the Nilla Wafers and align them in the 16x16 pan until the bottom of the pan is covered. Now take the bananas and cover the Nilla wafers with the bananas. Take the pudding mixture and cover the wafers and bananas. Repeat this process until ingredients are you have pudding on the top and no more bananas. Take left over Nilla wafers. Crumble over the top of the pudding.
Cover and set in refrigerator for 30 min. Serve chilled.
