Preheat oven to 350 degrees. Place peeled bananas in a bowl and mash with a fork or potato masher. Measure 1 cup of bananas and place in your stand mixer or a bowl. Add egg, salt, and mix well. Slowly mix oats into banana egg batter. If using traditional oats place in blender or food processor, and process for 30 seconds to a minute before adding to the batter. Fold in chocolate chips. Spoon cookies onto a greased cookie sheet or one lined with a silicon baking mat and bake for 15 minutes. Let cool and enjoy!
