Creating your own Banana Pudding Lasagna is simple if you follow these easy steps:

1. Prepare the Pudding: In a large mixing bowl, whisk together the cold milk and instant vanilla pudding mix until well combined. Let it sit for about 5 minutes to thicken.
2. Add Whipped Topping: Fold in the whipped topping and vanilla extract into the pudding mixture until smooth and creamy.
3. Layer the Ingredients: In a 9×13 inch dish, start by placing a layer of graham crackers at the bottom.
4. Add Pudding Mixture: Spread half of the pudding mixture over the layer of graham crackers.
5. Layer Bananas: Add a layer of sliced bananas over the pudding mixture.
6. Repeat Layers: Add another layer of graham crackers, followed by the remaining pudding mixture, and top with more sliced bananas.
7. Final Layer: Finish with a final layer of graham crackers on top.
8. Chill: Cover the dish with plastic wrap and refrigerate for at least 4 hours or overnight to allow the flavors to meld.
9. Serve: When ready to serve, you can garnish with crushed Nilla wafers or additional sliced bananas, if desired.

Following these steps will result in a deliciously layered Banana Pudding Lasagna that is sure to impress.
