4-Ingredient Peanut Butter Oatmeal Cookies

Peanut butter oatmeal cookies made with just 4 ingredients and one bowl. All you need is oatmeal, peanut butter, bananas, and chocolate chips! These cookies are moist, chewy, naturally gluten-free, and easily made vegan. They are great as a grab-n-go breakfast, after-school treat, or sweet treat in the morning or afternoon.

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, I decided to do a version with peanut butter. (If you want a no-bake option, my Healthy No-Bake Cookies are what you’re looking for.)

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.
• 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.
