Open one bag of mini Nilla wafers and empty into a bowl.
Open one pudding cup and add a heaping spoonful of of pudding to the bottom of the bag.
Now add 5-6 mini Nilla wafers then 4-5 thin sliced bananas.
Repeat with pudding, wafers, and bananas two more times.
Top with a couple spoonfuls of Cool Whip.
Then garnish with one wafer and one banana slice. I also added some crumbs for the wafers on top.
Repeat with remaining bags and ingredients.
Serve immediately with spoons and enjoy.
