Start by assembling all necessary ingredients for the dish.
In a spacious bowl, combine milk and pudding mix; whisk vigorously for 2 minutes until blended. Then, introduce the condensed milk and mix until the mixture is silky.
Add vanilla extract to the mixture, followed by gently folding in the whipped topping to create a light and airy texture.
In a clear serving bowl, create layers by alternating between vanilla wafers, fresh banana slices, and the creamy pudding mixture.
For optimal flavor, refrigerate the layered delight for at least one hour before enjoying. Before serving, sprinkle with additional crushed wafers for extra crunch.
