Preheat the oven to 350°F (175°C) and line an 8x8 inch baking pan with parchment paper.

In a large mixing bowl, combine the mashed bananas, peanut butter, honey, and vanilla extract until smooth.

Add the rolled oats, cinnamon, and salt to the wet mixture, stirring until all oats are thoroughly coated.

Fold in the chocolate chips evenly.

Transfer the mixture to the prepared baking pan and press down firmly with a spatula to create an even layer.

Bake for 20 to 25 minutes or until the edges are golden brown and the center feels firm to the touch.

Remove from the oven and allow the bars to cool completely in the pan before slicing into 12 rectangular bars.
