If you know me, you know that I’m all about healthy cookies and fully support the idea that cookies can be a nutritious option for breakfast when you’re short on time. This recipe was inspired by my 3-Ingredient Banana Oatmeal Cookies! They were such a big hit, that I decided to do a version with peanut butter (I just love the combination of oatmeal and peanut butter – I even have an oatmeal breakfast smoothie with peanut butter to prove it, lol!).

Like our no-bake oatmeal energy balls, these cookies are free of processed sugar and flour, gluten-free, portable, and perfect as a pre or post-workout snack.

They were also a major hit with my family (which always makes me happy)! They’re super easy to make, only require 4 ingredients, one bowl and they are the perfect snacks to have on hand when you’re craving something sweet. The flavor combination of bananas, peanut butter, and chocolate is classic and one of my favorites. Even your kiddos will love these!

Ingredients Needed:

There’s a good chance you have everything you need for this easy recipe! Here’s the lineup:

Bananas – Use super ripe bananas to naturally sweeten and add moisture to these cookies.
Peanut butter – Adds delicious flavor and healthy fats. Feel free to use almond butter or sunflower seed butter (or any nut butter you have on hand). You can even use homemade peanut butter!
Oats – For these cookies, you need regular old-fashioned rolled oats. If you want to keep them gluten-free, I suggest using certified gluten-free rolled oats.
Chocolate chips – I like to use semi-sweet morsels in these cookies, but feel free to use your favorite baking chips. Use dairy-free baking chips, like these to keep this recipe dairy-free and vegan.
