These yummy cookie bars really hit the spot!
Preheat oven to 350 degrees. Line a 9x9-inch pan with parchment paper or foil. Spray with cooking spray. Set aside.
In a large mixing bowl, add the egg, bananas, sugars, butter and vanilla. Beat with a hand mixer on medium-high until well combined, about 4 minutes. The mixture will have pieces of banana and be slightly runny.
Scrape down the sides of the bowl. Add oats, flour, cinnamon, baking soda and salt. Beat with hand mixer on low speed until just combined, about 1 minute.
Scrape down sides of bowl. Add chocolate chips and stir to combine.
Place mixture into baking pan and spread into a smooth, flat layer using a spatula.
Bake for about 25 minutes. Cool for about 30 minutes in pan and then slice into bars.
