Step 1

Prepare pudding according to package instructions. Refrigerate and set aside.

Step 2

Place vanilla wafer cookies in a single layer on the bottom of a 11 x 7-inch baking dish. I used 24 cookies for each layer.

Step 3

Use a spatula to spread half of the prepared pudding (approximately 1 cup) over the cookies.

Step 4

Top pudding with a single layer of banana slices.

Step 5

Repeat layers, starting with cookies.

Step 6

Top final layer of banana slices with whipped topping. Refrigerate at least one hour, or until ready to serve. Just before serving, garnish with extra vanilla wafers and sliced banana, if desired.
