Creating Banana Pudding Bars is straightforward if you follow these steps carefully:

1. Preheat Oven: Preheat your oven to 350°F (175°C).

2. Prepare the Crust: In a bowl, combine crushed vanilla wafers with melted butter. Mix until well combined.

3. Press Crust in Pan: Firmly press the mixture into the bottom of a greased 9×13 inch baking dish to form an even layer.

4. Bake the Crust: Place the crust in the preheated oven and bake for 10-12 minutes until lightly golden. Remove and let cool.

5. Make the Pudding: In another large mixing bowl, combine instant vanilla pudding and milk. Whisk until the mixture thickens, which should take about 2 minutes.

6. Layer Bananas: Once the pudding is ready, layer the sliced bananas evenly over the cooled crust.

7. Spread Pudding: Pour the vanilla pudding mixture over the banana layer, spreading it evenly.

8. Chill: Cover the dish with plastic wrap and refrigerate for about 1 hour to let the pudding set.

9. Add Whipped Cream: After chilling, remove the bars from the fridge and spread the whipped cream over the pudding layer.

10. Garnish: Top with additional sliced bananas and chocolate shavings or graham cracker crumbs if desired.

11. Slice and Serve: Cut into squares and enjoy!
