In a large mixing bowl, whisk together pudding mix and milk.

Divide half of the pudding mixture among 3 cups (we used the 9 oz dessert cups).

Slice your bananas, and divide the banana slices between the cups.

Add a sprinkle of chopped walnuts to each cup.

Divide the remaining pudding mixture evenly among the cups.

Add the cool whip to a piping bag with a star tip. Top each cup with a swirl of cool whip.

Sprinkle with sprinkles and top with a maraschino cherry.
