Step 1

Preheat oven to 350° F.

Step 2

Spray a 13x9-inch cake pan with cooking spray. Line with parchment paper, leaving an overhang over the sides. This will help you lift the bars out of the pan later.

Step 3

In a food processor, blend together flour, butter, powdered sugar, and salt until the mixture resembles coarse sand. This will not look like dough – that’s ok! Press firmly into the bottom of the prepared pan. Bake until the edges are golden, about 20 minutes. Let cool completely.

Step 4

In a large bowl, whisk together the sweetened condensed milk and whole milk to combine. Whisk in the pudding mix. Whisk for two minutes.

Step 5

Spread half of the pudding mixture over the cooled crust. Top evenly with the sliced bananas. Spread the remaining pudding over the top. Cover and refrigerate for at least 2-3 hours.

Step 6

Spread the thawed whipped topping over the top of the filling.

Step 7

Use the parchment paper to lift the bars out of the pan. Cut into slices and serve.

Step 8

If desired, garnish with additional slices of banana or vanilla wafer crumbs just before serving.
