Ingredients
  

  • 2 ripe bananas
  • 1 cup oats (either quick or rolled oats)
  • ¼ teaspoon salt

Instructions
 

  • Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
  • In a medium-sized mixing bowl, peel the bananas and mash them thoroughly with a fork or potato masher until mostly smooth with a few small lumps remaining.
  • Add the oatmeal and salt to the mashed bananas. Stir the mixture well until all ingredients are fully combined and the oatmeal is evenly coated with the mashed bananas.
  • Using a tablespoon or a small cookie scoop, drop spoonfuls of the mixture onto the prepared baking sheet. Space them about 2 inches apart. Once placed, flatten each cookie slightly using the back of the spoon or your fingers, until they're about ¼ inch thick.
  • Place the baking sheet in the preheated oven and bake for approximately 15 minutes, or until the edges of the cookies turn golden brown and they are firm to the touch.
  • Remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes. Transfer to a cooling rack to cool completely. Once cooled, serve and enjoy!

Notes

Portion Control: Each cookie contains natural sugars from the banana, making them naturally portion-controlled compared to traditional cookies. 
Flavor Development: The banana flavor will be quite prominent when the cookies are fresh, but mellows after a day of storage. The oats absorb some of the banana moisture, creating a more balanced flavor profile over time.
Texture Expectations: These cookies have a uniquely soft and chewy texture that's different from traditional butter-based cookies. They're more similar to breakfast bars or energy bites in consistency. 
Storage: These cookies can be stored in an airtight container at room temperature for up to 3 days.
