Creating No-Bake Southern Banana Pudding is simple if you follow these easy steps:

1. Prepare the Pudding: In a large bowl, whisk together the instant vanilla pudding mix and whole milk for about 2 minutes until well blended and thickened.
2. Add Whipped Topping: Gently fold in the thawed whipped topping and vanilla extract until fully combined and fluffy.
3. Layer the Dish: In a 9×13 inch baking dish, start layering with a single layer of vanilla wafers, spreading them evenly across the bottom.
4. Add Bananas: Place a layer of sliced bananas over the vanilla wafers.
5. Spread Pudding Mixture: Add a generous layer of the pudding mixture on top of the bananas, smoothing it out evenly.
6. Repeat Layers: Repeat the layering process: vanilla wafers, bananas, and pudding mixture until all ingredients are used, ending with a pudding layer on top.
7. Chill: Cover the dish tightly with plastic wrap and place it in the refrigerator for at least 4 hours, or preferably overnight. This helps the flavors meld together and allows the wafers to soften.
8. Serve: Once chilled, remove from the refrigerator. Optionally, top with crushed vanilla wafers for decoration before serving.

These steps will guide you through creating No-Bake Southern Banana Pudding effortlessly. Each layer adds complexity, resulting in a beautiful and delicious dessert.
