Peanut Butter Banana Cookies

Peanut Butter Banana Cookies
My youngest son is a very picky eater and even a little small for his age.  Lately I’ve been thinking a lot about ways to increase his calorie intake without it being in wasted calories and junk food.  We’re basically at a point where we let the kid eat whatever he wants, whenever he wants.

I came up with this recipe because he loves bananas and peanut butter is a good way to get some calories and protein in that are fairly good for him. Banana cookies – why not? I am not a baker, I’ve said it before and I say it again! These however were my first baking success from a recipe I tweaked myself! &I’m a little proud.

I’ve played with the measurements on these cookies quite a bit. If you prefer a more chewy cookie adjust the brown sugar a bit. Also don’t be afraid to let these rest in the fridge for a while. You could also easily scoop these out into balls, flash freeze them and then bake a few whenever you want.

These banana and peanut butter cookies are versatile and you can make them your own. Shhh I won’t tell if you add some chocolate chips too!

Peanut Butter Banana Cookies

Yield: 24 cookies
Prep Time: 15 minutes
Cook Time: 10 minutes
Additional Time: 30 minutes
Total Time: 55 minutes

I created these cookies for a very picky eater in our house. I made my cookies on the smaller side and was able to get 24 but these can easily be made larger for more bakery style cookies.


  • 1 over-ripe banana
  • 1 egg
  • 1/4 cup firmly packed brown sugar
  • 1/2 cup white sugar
  • 1/2 cup (113g) unsalted butter
  • 1/4 cup peanut butter
  • 1 Tbsp vanilla extract
  • 1/2 tsp salt
  • 3/4 teaspoon baking soda
  • 2 1/4c cups sifted all-purpose flour
  • peanuts for topping cookies (if desired)


  • In a large mixing bowl add brown sugar, white sugar, egg, and butter. Cream until smooth.
  • Next add peanut butter and continue mixing.
  • Add vanilla and banana, salt and baking soda making sure to break up the banana as much as possible.
  • Slowly add in flour to bring all together.
  • Place bowl into the refrigerator to chill for 30 minutes. If you leave it longer it's ok too, but a minimum of 30 minutes.

To Make More Shaped Cookies

  • Preheat oven to 350F.
  • Take a small amount of dough, about the size of ping-pong ball and shape into a ball.
  • Place on a cookie sheet.
  • You should be able to fit 12 on a large sheet. Press a peanut into the center slightly. Bake for approximately 8 minutes.
  • The cookies should be a light brown and still a bit soft
  • Remove from oven, and allow to cool for a 2-3 minutes and carefully transfer to a cooling rack.
  • Your cookies will be moist and delicious!
  • If you prefer a crunchier cookie, bake a little bit longer.
