Step 1: Prepare the Crust
Line a 9x9-inch baking dish with parchment paper.
In a bowl, mix graham cracker crumbs, melted butter, and sugar until combined.
Press firmly into the baking dish to form a crust.
Refrigerate while preparing the filling.
Step 2: Make the Cheesecake Filling
In a large bowl, beat cream cheese, sugar, and vanilla until smooth.
In a separate bowl, whisk together banana pudding mix and cold milk until thickened (about 2 minutes).
Fold the pudding into the cream cheese mixture.
Gently mix in the mashed banana.
Step 3: Assemble And Chill
Spread the cheesecake filling evenly over the crust.
Top with whipped topping and smooth it out.
Cover and chill for at least 4 hours (or overnight for best results).
Step 4: Serve And Garnish
Slice into bars and garnish with banana slices and crushed graham crackers.
Enjoy chilled!
