Create the layers for the banana pudding by placing vanilla wafers on the bottom and along the sides of a 9x9 baking dish.

Slice bananas and place on top of wafers.

Repeat layering process two more times or until the layers reach the top of the 9x9 pan, ending with a final layer of wafers for decorative purposes.

To make the pudding, add four cups of milk to a saucepan.

Add the two boxes of pudding and mix.

Over medium heat, bring the pudding mixture to a boil, stirring constantly. This will take approximately 10 minutes.

Once the pudding comes to a slow boil, remove from the heat, and pour carefully over the layers of wafers and bananas.

Place the banana pudding in the refrigerator for several hours until it is completely cool and firm.

Serve right from the refrigerator and top with whipped topping and extra wafers.
