01 - Combine crushed vanilla wafers and melted butter in a small bowl. Mix until evenly moistened. Spoon about 2 tablespoons into the bottom of each serving cup and press lightly to form the crust.
02 - Beat cream cheese, sugar, and vanilla extract in a medium bowl with a hand mixer until smooth and creamy.
03 - In a separate bowl, whip cold heavy cream until stiff peaks form. Gently fold whipped cream into the cream cheese mixture until fully combined.
04 - Whisk together banana pudding mix and cold milk in another bowl for 2 minutes until thickened.
05 - Spread cheesecake filling over the crust in each cup, using about half the mixture.
06 - Arrange a layer of sliced bananas over the cheesecake filling.
07 - Spoon banana pudding over the banana layer, dividing evenly among cups.
08 - Spread remaining cheesecake mixture over the pudding layer in each cup.
09 - Sprinkle each cup with additional wafer crumbs, more banana slices, and a dollop of whipped cream if desired.
10 - Cover and refrigerate cups for at least 2 hours before serving to allow flavors to meld.
