These PEANUT BUTTER BANANA COOKIES are the perfect cross between banana bread and peanut butter cookies! Thick, cake-like cookies loaded with peanut butter, banana, oats, and chocolate chips! You’ll want to keep your cookie jar stocked with these cookies.

Is my family the only one that seems to go through phases with bananas?

Like, they want them so I buy them and then they eat them all super quickly.

So I buy more and…nope. No one in this house eats bananas anymore.

I’d be annoyed, but instead I just turn the bananas into things like my classic banana bread. Or maybe my chocolate banana bread. Or how about this blueberry banana bread?

I mean, the bananas aren’t going to go to waste, whether my family eats them for a snack or not. 😉

This time around, I took that bunch of bananas and made peanut butter banana cookies.

We love these thick cookies!

Normally, I’m not a huge fan of cake-y cookies, but it works here, because you’ve got a banana bread vibe going on, but in cookie form! So fun!

Cookie Scoop: Using a cookie scoop ensures that your cookies are all the same size, which means they’ll bake evenly! Plus, cookie scoops just make the job super easy. We have 3 sizes, but for this cookie recipe, we used a large scoop to make big, fat, bakery-style cookies.

Mixer: This recipe is easy to mix with either a stand mixer or a hand mixer. Either work great for creaming the butter and mixing the cookies properly.

Mashed Bananas:

This recipe calls for 3 medium bananas, mashed. That generally equals around 1 cup of mashed banana.

How To Freeze!

Cookies freeze beautifully either before baking or after!

To freeze before baking (our preferred method), scoop dough into balls and place on a cookie sheet in the freezer for one hour. Transfer the hardened cookie dough to a freezer safe bag and freeze for up to 3 months. Bake as directed, adding an extra minute or two in the oven, if needed.

To freeze already baked cookies, cool completely and then wrap individually in plastic wrap and place in a freezer bag. Thaw overnight on the counter before eating.

Prep15 minutes

Cook12 minutes

Total27 minutes

Ingredients

  • 1/2 cup butter softened
  • 1/2 cup creamy peanut butter
  • 1/2 cup white sugar
  • 1/2 cup brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 2 cups rolled oats
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3 medium ripe bananas mashed
  • 1 cup semisweet chocolate chips

Instructions

  • Preheat oven to 375 degrees. Line a baking sheet with parchment or spray with nonstick spray.

  • In the bowl of your mixer cream together the butter, peanut butter, and sugars until light and fluffy.

  • Beat in the eggs and vanilla.

  • In a separate bowl stir together the flour, oatmeal, baking soda, and salt.

  • Add the dry ingredients to the butter and sugar and beat until just combined.

  • Cool on a wire rack.

Tips & Notes:

Use a cookie scoop for evenly sized cookies. This recipe calls for a large scoop, which will make large, bakery-style cookies. To use a smaller scoop, reduce the bake time accordingly. 

You may use crunchy peanut butter, if preferred.
