Gather your ingredients and a 9x13" baking dish, a whisk, and a large bowl.
In a large bowl, whisk together the pudding mix and milk until smooth. Then whisk in half of the whipped topping.
Use the majority of wafer cookies to form the base layer in the baking dish.
Layer banana slices over the cookies, then add half of the pudding mixture. Repeat with remaining ingredients.
Crush remaining cookies and sprinkle on top. Optionally, add leftover banana slices.
