With its nostalgic flavors and impressive presentation, these decadent banana cream pie bars will become a crowd-pleasing favorite at any gathering.
Make the Banana Filling: In a blender or food processor, add the egg yolks, lemon juice, cornstarch, butter, sugar, and bananas (in that order). Pulse until smooth.
Pour the mixture into a medium saucepan and warm over medium heat, stirring constantly, until thickened, about 10 minutes.
Remove the pot from the heat and strain the curd through a fine-mesh sieve into a wide, shallow bowl. Press a sheet of plastic wrap directly onto the surface, then set aside to cool completely.
Make the Crust: In a medium bowl, mix the Nilla Wafers crumbs and melted butter until moistened. It should resemble wet sand.
Line a 9x9 baking dish with parchment paper and press the mixture firmly into the bottom. Use the bottom of a measuring cup to compact the crumbs tightly, then chill for at least 30 minutes.
Make the Cheesecake Layer: In a large bowl, beat the softened cream cheese and powdered sugar until smooth and thick.
In a separate bowl, whip the cream and vanilla until stiff peaks form. Add to the cream cheese mixture and fold gently to combine.
Spread the cream cheese mixture evenly over the chilled crust. Cover and chill for 20-30 minutes, then spread the cooled banana filling evenly over the top.
Make the Whipped Cream: In a large, cold bowl, whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Spread the whipped cream evenly over the banana layer. Cover and refrigerate for at least 4 hours (or overnight).
Garnish with sliced banana, crushed Nilla Wafers, and a drizzle of caramel, if desired. Slice into bars, serve, and enjoy!
