Just 3 Ingredients for Peanut Butter Banana Cookies

How Do I Customize These Peanut Butter Banana Cookies?

Customizing these peanut butter banana cookies is pretty simple. You can change everything from the peanut butter to the add-ins. Check it out:

To Substitute the Peanut Butter: You can go a little wild here and use something fun like homemade cashew butter, pecan butter, or sunflower seed butter. Or, you can stick to a closer substitute and use something like almond butter.

To Substitute the Nuts: I recommend using finely chopped pecans or walnuts in these banana peanut butter cookies. However, you can use any kind of nut or seed that you’d like. (I’m not 100% sure about tiny seeds like chia seeds, which can cover a ton of ground and tend to make things gooey, but sunflower seeds and pumpkin seeds could be a good choice.)

You can go in an entirely different direction and add chocolate chips, dried fruit, or maybe something fun like chopped pretzels instead of nuts! If using dried fruits, just make sure to finely chop them so you don’t get any huge pieces that could make your peanut butter banana cookies fall apart.

How to Make Peanut Butter Banana Cookies

Making these peanut butter banana cookies is easy. The hard part? Trying not to eat them all at once! Check out how truly easy it is to make these scrumptious gems:

First, start by preheating the oven to 350°F. Then, grab a baking sheet and coat it in parchment.

Then, peel a medium-sized banana and toss it into a mixing bowl. Grab a pastry cutter and mash that banana until it’s nearly smooth.

Measure out your peanut butter and add it to the bananas.

Next, pour in the oats. Fold the oats in until you get a wet and sticky dough.

Now, fold in your favorite add-ins.

Grab a cookie scoop and use it to scoop and drop balls of cookie dough onto the prepared baking sheet. Flatten with a fork.

Then, bake for about 12 minutes. Cool and enjoy the easiest ever 3 ingredient peanut butter banana cookies!

Storing & Freezing These Delectable Banana Peanut Butter Cookies

Refrigerator: Make sure to always cool your baked goods completely before storing them. These banana peanut butter cookies are no exception. 😉 Cool cookies completely, then pop them into an airtight container and tuck them into the fridge. Here, you can keep the cookies for 3-5 days. 

Freezer: If you’re keen on keeping these peanut butter banana cookies for longer, I recommend storing them in the freezer. Place cookies in an airtight, freezer-friendly container and tuck them into the freezer. They’ll keep for 1-2 months here. Just make sure to thaw the cookies at room temperature for about 10 minutes before enjoying.

How to Reheat Cookies: If you can’t wait for the cookies to thaw, you can place them onto a plate and microwave in 10-second increments until just warm. Or, you can pop those cookies into a toaster oven and heat at 350°F for 3-6 minutes, or until warm. Enjoy!
