Let’s dive into creating this layered masterpiece, step by step:

1. Preheat your oven to 325°F. Grease a 9-inch springform pan and set it aside.
2. In a medium bowl, mix the vanilla wafer crumbs with the melted butter until well combined. Press this mixture firmly into the bottom of the prepared pan to form the crust.
3. In a large mixing bowl, beat the cream cheese and sugar together until smooth and creamy, about 3 minutes. Stir in the mashed bananas and vanilla extract.
4. Add the eggs, one at a time, beating well after each addition. Pour the cheesecake batter over the crust in the pan.
5. In a separate bowl, whisk together the pudding mix, milk, and heavy cream until thickened. Gently fold this mixture into the cheesecake batter.
6. Bake for 60-70 minutes, or until the center is set but still slightly jiggly. Turn off the oven and leave the cheesecake inside for an hour to cool gradually.
7. Remove from the oven and refrigerate for at least 4 hours, or overnight, to allow the flavors to meld beautifully.

Remember, patience is key with cheesecake—a lesson I learned from countless hours in Nonna Rosa’s kitchen. The longer it chills, the more harmonious the flavors become.
