These Peanut Butter Banana Chocolate Chip Oatmeal Cookies are soft, chewy, moist, and bursting with banana, peanut butter, and chocolate flavor. The banana creates a wonderfully soft cookie that will last days, and the oatmeal gives it just the right bite.

The title of these cookies is a mouthful, I know, but let me just be honest when I say they are so, so, so good! If you're a peanut butter, banana, and chocolate fan, you are going to love these, hands down! My husband, who is not a peanut butter or banana lover actually enjoyed them. He said the texture of the cookies was wonderful.

Today, June 12th is National Peanut Butter Cookie Day, so of course I had to join in and create a cookie just for today! And these don't disappoint at all. They are just bursting with all the right flavor, from the creamy peanut butter, to the ripe banana, you just can't go wrong. Throw in some chocolate and you have the absolute perfect cookie. And if you want to convince yourself they're healthy because they have oatmeal, then who am I to stop you? 😉

To create this cookie, I used my Peanut Butter Chocolate Chip Cookie recipe as a base, and added banana and oatmeal. If you haven't tried my base recipe, I highly recommend them. They are bursting with peanut butter flavor, they're soft, and absolutely delicious.

So what makes these so perfect?

Texture: These cookies have a slightly crispy edge with an absolutely moist center that is created with the addition of the banana. The oatmeal creates turns these cookies from soft and moist into soft, moist, with an edgy texture. Just make them and see for yourself!

Flavor: The flavor is just bursting with peanut butter, banana, and chocolate. The perfect combination. There's a good amount of ALL three.

Effort: These cookies honestly don't require much. For the most part, all these ingredients can be found in the pantry. And once you have all the ingredients measured out, it takes absolutely no time to put together.

How To Make These Cookies

These cookies come together pretty easily and as long as you've measured your ingredients correctly, you should get perfect results.

First, cream together the butter and sugars until light and fluffy for a few minutes. Next, add in the creamy peanut butter and banana and mix until combined. Then add in the egg and vanilla extract and mix until combined. Add in the flour, baking soda, baking powder and salt and mix until just incorporated. Next add in the quick oats and mix until just combined. Last, add the chopped chocolate and using a spatula, mix until just incorporated.

Once the dough comes together, cover it and let it chill for about 30 minutes before baking.

Preheat the oven to 350 degrees, line a baking sheet with parchment paper. Scoop the dough using a 1.5 tablespoon cookie scoop and drop them on the baking sheet making sure to keep them separated. Bake for 12-14 minutes.

Remove from oven and let them cool in the pan for a few minutes before moving them to a cooling rack to cool completely.

Do I Have To Chill The Dough?

Because the creamy peanut butter and banana both are soft ingredients, it yields a pretty soft dough, so it's important to chill the dough for at least 30 minutes to avoid overspreading of the cookies while baking.

I highly recommend keeping the dough chilled between bakes (you'll be baking several trays since this recipe yields 26 cookies), especially during the hotter summer months.

Frequently Asked Questions

YES! Once chilled, scoop the cookies into balls, place them on a sheet and freeze them for at least 30 minutes, then transfer all the dough balls into an airtight container or ziploc bag. It should keep for a couple months. When you're ready to bake, add a few minutes to the baking time since they're frozen.

How Can I Store The Cookies?

These cookies are moist and soft, but the oatmeal could draw out all the moisture, so just make sure to store them in an airtight container or ziploc bag at room temperature for a few days. I've never been able to keep them longer than 2 days because they're always eaten up!

Can I Use a Natural Peanut Butter?

It's best not to use a peanut butter that only contains peanuts because they won't really work. So for this recipe, purchase a peanut butter that has added oils. I use Skippy Peanut Butter. Unfortunately, if you're trying to go 100% the healthy and natural route, this is probably not the best recipe to do that with.
