1Take a large bowl and whisk together 5 cups of Milk (or a little less to make thicker) with 2 boxes of Banana Pudding Mix for about 4 minutes. Then stick in the freezer for 5 minutes until it thickens up.
2Place a single layer of Nilla Wafers on the bottom of a 9"x3" pan.
3Cut Bananas into thin slices, then layer over the Nilla Wafers.
4Cover the Nilla Wafers and Bananas with the half of the bowl of Vanilla Pudding.
5Do another layer of Nilla Wafers and Bananas and cover once more with the rest of the Vanilla pudding.
6Take an 8 OZ container of Whipped Topping and add 1 Teaspoon of Banana Extract. Mix well, keeping the Whipped Topping fluffy. (Will only have a very light banana flavor.)
7Crush the remaining Nilla Wafers until there are very small pieces.
8Top dish with Whipped Topping. Then cover with the Nilla Wafer crumbs. Cover and refrigerate for at least two hours. Serve chilled.
