Peanut Butter Banana Oatmeal Cookies

Peanut Butter Banana Oatmeal Cookies

Drop cookies, made of dough that is casually shaped into a ball and dropped onto a cookie sheet, are not always the most attention-getting cookies. I think that they’re probably the most often made type of cookie, since they are very quick and easy when compared to cut-out cookies, but they don’t hold a candle to the cutouts when it comes to presentation. That being said, drop cookies are usually packed with lots of great flavors and I think that we’ve all learned to appreciate them, sometimes in spite of a plain outward appearance.

These Peanut Butter Banana Oatmeal Cookies definitely fall into the plain-but-surprisingly-flavorful category. The have peanut butter, oats, and mashed banana in them. I actually was inspired to make them by the banana peanut butter I tried recently, so I put these together by mixing some into my Banana Oatmeal Cookies. The fact that I know the flavor combination is a good one in general didn’t hurt things, either.

The finished cookies looked like your basic oatmeal cookies, but tasted like a cross between a peanut butter cookie and banana bread. The banana flavor was good, but not overwhelming, and the peanut butter added a nice nuttiness to the whole thing. The cookies stayed moist, slightly chewy and fresh tasting for several days when stored in an airtight container, so these are a great option if you want to bake a batch over the weekend and keep it around during the week. I used smooth peanut butter for these cookies, but using crunchy would add a little bit more texture if that’s your peanut butter preference at home.

Peanut Butter Banana Oatmeal Cookies
1 cup all purpose flour
1/2 tsp baking powder
1/2 tsp baking soda
1/4 tsp salt
1/2 cup brown sugar
1/2 cup sugar
2 tbsp butter, room temperature
1 large egg
1/2 cup peanut butter
1/4 cup mashed banana (from 1 sm/med)
1 1/2 cups quick-cooking rolled oats (not instant)

Preheat oven to 350F. Line a baking sheet with parchment paper.
In a medium bowl, whisk together flour, baking powder, baking soda and salt.
In a large bowl, cream together sugars and butter. Beat in egg until smooth, then mix in the peanut butter and mashed banana. Working by hand or with a mixer on low speed, blend dry ingredients into the peanut butter mixture. Stir in the oats.
Shape dough into tablespoons and place on baking sheet, flattening each slightly with your fingers.
Bake for 10-12 minutes, until cookies just begin to turn golden around the edges.
Cool on a wire rack.

Makes approx 2 dozen.

    Drop cookies are the absolute best. There’s no fuss so it’s all about the cookie.

    I love the combination of peanut butter and banana together!

    These look awesome! Thanks for the idea of what I can do with my extra bananas other than banana bread.

    I love banana in cookies…the best kept secret if you ask me! I’ll have to add these to my to-do list! I recently made banana toffee white chocolate cookies. Sounds like a weird combo, but they were a big hit.

    You must be a psychic! How did you know that I have a defrosted banana in my fridge just looking for this cookie?

    And I love, love, love that there are only 2 tablespoons of butter in this!

    I’ll let you know how they turn out. :)

    Love this recipe! I added some cinnamon to mine. It’s an unexpected and very yummy combo.

    Hi Nicole

    How did you incorporate the banana peanut butter into the recipe. Did you use the banana peanut butter in place of the regular peanut butter. If so, did you still use the fresh banana in the recipe.

  18. Nicole May 26

    Jackie - The recipe calls for both pureed bananas and peanut butter - regardless of whether you have a “flavored peanut butter” at your disposal to add in, as well.

  19. Jackie May 26

    Hi Nicole

    Well how much banana peanutbutter did you add in?

  20. Kristin May 30

    Yummy! I doubled your recipe, added a teaspoon of vanilla and used 3 medium bananas.

    When I first saw this recipe, I knew I had to try it. I finally made them yesterday. I added chocolate chips to the batch. They turned out wonderful! These are a bit addicting.

  22. Laura Jul 29

    HOLY AWESOMENESS!!! Excellent cookie recipe. I upped it a bit by adding some white chocolate chips on some and milk chocolate on others on the top prior to baking - whole new level!
    Wonderful recipe!!!
    THANK YOU!!

    These are the BEST cookies!! I love that they are semi-healthy, even though I couldn’t resist adding a few chocolate chips :-)

    Amazing cookies - thank you so much for this recipe! My husband is newly diagnosed with high cholesterol, and I am trying to get oatmeal into him anyway I can (he is not fond of it as plain cereal). I actually cut out the butter completely and creamed the peanut butter with the sugars and there seems to be no loss of quality/taste. I used 1/2 whole wheat and 1/2 white flour and added a handful of pecans, which are supposed to help raise good cholesterol. They turned out great!

    I made these today and they were great!
