Banana Cheesecake

Preheat oven to 350 degrees F. Coat a 9-inch springform pan with cooking spray and set aside. In a medium bowl, combine the Nilla Wafer crumbs (use a food processor to form crumbs or put them into a large ziploc bag and break them down using a heavy spoon) and the butter. Stir until crumbly. Press firmly into the bottom of the prepared pan and bake for 8 minutes in the preheated oven.
In a small bowl, combine the mashed bananas and lemon juice. Set aside. In a large bowl, combine the cream cheese and sugar. Mix on medium speed (hand-held or stand-up mixer) for 2-3 minutes, or until mixture is smooth.
Add the sour cream and vanilla and mix on medium speed for another 2-3 minutes, or until smooth and creamy. Add the eggs and mix until fully incorporated. Fold in the banana mixture. Pour the mixture over the prepared crust and bake for 60-70 minutes in the preheated oven, or until center is cooked through (the center should jiggle with a gentle shake).
Cover and chill for a minimum of 1 hour. Cut into slices and top with Nilla wafers, banana slices and caramel sauce (if desired).
