Servings 4 doz


  • 1 cup mashed bananas this is about two large bananas
  • 3/4 cup salted butter softened (not melted!!)
  • 1 cup brown sugar firmly packed
  • 1/2 cup white sugar
  • 1 large egg room temperature
  • 1 tsp vanilla extract
  • 1 1/2 cups all purpose flour
  • 1/2 tsp cinnamon
  • 1 tsp baking soda
  • 1/4 tsp ground cloves
  • 2 tsp cornstarch
  • 3 cups old fashioned oats not steel cut, mostly for texture reasons


  • Preheat oven to 350 degrees and line your cookie sheets with parchment paper.
  • In a large bowl or your stand mixer, combine butter, brown sugar, sugar, egg, vanilla extract and mashed bananas. I like to combine the egg, butter and bananas first.
  • Next add flour, cinnamon, baking soda, cloves and cornstarch and mix.
  • Finally add in oats.
  • Using a tablespoon cookie scoop, place dough onto a cookie sheet. Flatten dough with the back of the scoop a little bit so it forms a disk shape. The dough will be a little sticky. Your oatmeal banana cookies will spread a little when baked.
  • Bake for 10-12 minutes or until edges just start to turn brown.
  • Cool on cookie sheet for 3-4 minutes, then move to cooling rack with a cookie spatula to finish cooling.
