Creating Banana Pudding Cheesecake can be simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 325°F (163°C). Grease a 9-inch springform pan with non-stick spray.
2. Make the Crust: In a medium bowl, combine Nilla wafer crumbs, granulated sugar, and melted butter. Press the mixture firmly into the bottom of the prepared springform pan.
3. Prepare the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese until smooth. Gradually add granulated sugar and vanilla extract, mixing until well combined.
4. Add Eggs: Add the eggs one at a time, mixing on low speed after each addition until just combined. Do not overmix.
5. Incorporate Bananas: Gently fold in the mashed bananas until evenly distributed throughout the cheesecake mixture.
6. Bake: Pour the cheesecake filling over the crust in the springform pan. Bake for 60 minutes or until the center is set but slightly jiggly.
7. Cool: Turn off the oven and crack the oven door. Let the cheesecake cool in the oven for 1 hour to prevent cracking.
8. Chill: Remove the cheesecake from the oven and refrigerate for at least 30 minutes.
9. Prepare Banana Pudding Layer: In a medium bowl, whisk together the instant vanilla pudding mix and cold milk until thickened. Fold in the whipped cream until fully combined.
10. Spread Pudding Layer: Once the cheesecake has cooled, spread the banana pudding layer evenly over the top.
11. Add Sliced Bananas: Arrange sliced bananas on top of the pudding layer.
12. Garnish: Finish with whipped cream and a sprinkle of crushed Nilla wafers for added texture.
