Cut half of 1 small banana into slices; keep other half in the peel and save for another use. Layer 1 (5-oz.) glass with 1 Tbsp. thawed nondairy whipped topping, one-fourth of banana slices, 1 Tbsp. vanilla pudding, another fourth of banana slices, and 1 vanilla wafer. Repeat. Dollop with 1 Tbsp. thawed nondairy whipped topping.
Note: For testing purposes only, we used Hunt's Snack Pack Vanilla Pudding. One (3.5-oz.) pudding cup yields 6 Tbsp. pudding.
If you're serving a crowd, simply prepare the recipe as many times as needed.
