Deliciously moist and chewy with a texture that is customizable to your preference (contingent upon how fine you grind your oats), this banana cookie recipe is simply delish. 

I recently did a poll on Instagram asking about adding cinnamon to banana desserts and wow, people are PASSIONATE about banana and cinnamon. I had never tried pairing the two before, but it is actually a match made in heaven. And coating the outside in a cinnamon-sugar mixture just transforms these cookies in the best way – essentially making it into an exotic cousin of the snickerdoodle.

Banana Cookie Ingredients

Banana Cookie Base

  • Salted butter, softened – I always, always use salted butter. If you don’t have any on hand, you can use unsalted and add an extra pinch of salt to the dough. 
  • Granulated sugar – equal parts granulated and brown sugar to give the cookie a little crisp on the edges but keep it soft and chewy in the center.
  • Brown sugar
  • Banana, mashed (1/4 cup) – Use approx 1/4 cup of mashed banana, but I’ll be honest here, I usually just toss the entire whole banana into my mixer and let it do the work while the butter and sugars are creaming.
  • vanilla
  • All purpose flour
  • Rolled oats – we will Learn how to make oat flour in the recipe or you can leave the oats a bit rougher if you prefer.
  • baking soda
  • Cinnamon – Okay, the cinnamon. Try them at least once with it!! I hadn’t ever tried putting cinnamon in banana desserts before Instagram convinced me too, but I actually really liked it!
  • salt

  4. Add the flour, blended rolled oats (into a rough oat flour), baking soda, cinnamon, and salt to the mixer. Mix until a soft dough or thick batter forms.

  6. Roll each portion into the cinnamon and sugar mixture and then arrange on a cookie sheet.
  7. Bake at 350° F for 9-11 minutes or until the cookies puff up slightly, and the centers of the cookie no longer look wet.

    These taste like eating banana bread but in cookie form, except somehow better, especially since it’s a cookie! I was so pleased with how they turned out. I want to add that I always have to add more flour,and sometimes baking powder. It may be something to do with where I live, so some recipe tweaking is always needed, but boy oh boy are these tasty!! Thanks for another great recipe! 💛
