Add the pudding mix and 3 cups of milk and mix well scraping bottom and sides of the bowl as your mixing. Add half of the tub of cool whip and fold in until mixed well, fold in the vanilla extract.
2Slice all 4 bananas.Layer in a 9x13 pan in the following order.
2 sliced bananas

Top with remaining whip cream and spread until top is covered.
Crush up any remaining vanilla wafers and sprinkle over the top.
Cover tightly and refrigerate 3 hours up to overnight. I like it better overnight.
