Ingredients Equipment Method Notes

Ingredients
  

  • 1.5 cups All-Purpose Flour
  • 1.5 cups Old-Fashioned Rolled Oats
  • 1 tsp Baking Soda
  • 1 tsp Ground Cinnamon
  • 0.5 tsp Salt
  • 0.5 cup Unsalted Butter softened
  • 0.5 cup Light Brown Sugar packed
  • 0.5 cup Granulated Sugar
  • 1 Large Egg
  • 1 tsp Vanilla Extract
  • 1 cup Mashed Ripe Bananas about 2-3 medium bananas

Equipment

  • 2 Baking Sheets
  • 2 Mixing Bowls
  • 1 Electric Mixer

Method
 

  1. Preheat oven to 350°F (175°C). Line two large baking sheets with parchment paper.
  2. In a medium bowl, whisk together the flour, rolled oats, baking soda, cinnamon, and salt. Set aside.
  3. In a large bowl, beat the softened butter and both sugars with an electric mixer until light and fluffy, about 2-3 minutes.
  4. Beat in the egg and vanilla extract until just combined. Add the mashed bananas and mix until well incorporated.
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
  6. Drop rounded tablespoons of dough onto the prepared baking sheets, about 2 inches apart. Bake for 12-15 minutes, or until golden brown and set. Cool on the baking sheets for a few minutes before transferring to a wire rack.

Notes

For the best flavor, use very ripe, heavily speckled bananas.
Store cookies in an airtight container at room temperature for up to 3 days.
