Prepare the Pudding

1. Mix the Pudding: In a large bowl, whisk together the vanilla instant pudding mix and cold milk. Mix until smooth and thickened, about 2 minutes.
2. Make the Whipped Cream: In a separate bowl, beat the heavy whipping cream and powdered sugar using an electric mixer until stiff peaks form.
3. Combine the Pudding and Whipped Cream: Gently fold the whipped cream into the pudding mixture until fully combined. This will give your pudding a light and airy texture.

Assemble the Banana Pudding

1. Layer the Ingredients: Start by placing a layer of vanilla wafers at the bottom of a 9×13-inch dish or a trifle bowl.
2. Add Bananas: Layer the sliced bananas over the wafers, covering them evenly.
3. Spread the Pudding: Spoon half of the pudding mixture over the bananas, smoothing it out to cover the layers.
4. Repeat the Layers: Add another layer of vanilla wafers, followed by the remaining banana slices and then the rest of the pudding mixture.
5. Top with Wafer Crumbs: Finish by crushing a few vanilla wafers and sprinkling them over the top for an extra touch of crunch.

Chill and Serve

1. Refrigerate: Cover the dish with plastic wrap and refrigerate for at least 1 hour and 30 minutes, or until well-chilled.
2. Serve: Once chilled, serve the pudding in individual bowls or scoops from the dish, and enjoy!
