The ultimate prep ahead, no-bake summer dessert!
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.
Use a spatula to spread half of the prepared pudding (approximately 1 cup) over the cookies.
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.
For purposes of calculating nutrition information, I used sugar-free instant pudding mix and skim milk, as well as Lite Cool Whip. If you use other varieties of pudding and whipped topping, the nutrition facts will change.
