5-Ingredient Peanut Butter Banana Oatmeal Cookies | THM: E

Save for later!

A Trim Healthy Mama E cookie that tastes like more?!


These 5-Ingredient Peanut Butter Banana Oatmeal Cookies (well, six ingredients if you count the pinch of salt 😉 ) contain almost no fat, no gluten, no dairy, no eggs, and no special ingredients, but they are perfectly sweet and chewy little gems that kids and adults alike love!

Defatted peanut flour (one of my favorite sources of protein because I love peanut butter flavored everything!), is an excellent source of protein in this recipe, along with the protein you find in the rolled oats.

An energizing snack or breakfast, you can also pair these 5-Ingredient Peanut Butter Banana Oatmeal Cookies with almond milk, 0% fat Greek yogurt, low fat kefir, or an E friendly shake for even more protein if you’d like.

You definitely want ripe bananas for this recipe, since no other sweetener is called for. The riper, the better: when the yellow peel is completely speckled with brown spots, you have exactly what you’re looking for!

My 5 year-old daughter calls these “banana muffin cookies.” They taste so much like banana bread or muffins, but instead of being a Crossover with fat from eggs and oil, these cookies are energizing E snacks that only take 5 ingredients to make, and 5 minutes to prepare!

If do you want a Crossover (a great option for kids lunches!), these 5-Ingredient Peanut Butter Banana Oatmeal Cookies are also amazing with sugar-free chocolate chips, or chopped 85% chocolate, chopped walnuts, or shredded coconut. Just be sure to keep your add-ins to 1/4 cup or less; any more than that and your cookies won’t hold together very well.

  1. I’m going to love these and I know my kids will too! Definitely going to happen when we have overripe bananas next 🙂 Thank you!

    • I also wanted to know about this, because I have a friend with a peanut allergy. She also needs gluten free, which we do with the oats, but I’m not sure about a sub here.

  2. These make a quick, easy e go-snack for me and the littles and it’s a way to use up all the over ripe bananas in my freezer stash. Just be sure to cook them til they’re done so they’re not soggy! They’re more like a soft granola bar, and my 3 yr old great nephew loves me to have them as a snack after pre-school.

  3. I am a bit on the pregnant side so my sense of smell and taste buds have been compromised. I made this for our church gathering and kids and adults alike went back for seconds and took some with them so we’ll mark that down as a success. Thanks for another winner recipe.

  4. Would this work with substituting applesauce for the bananas? We have an allergy to bananas in the house.

  5. These are amazing, and so quick and simple to make! I made one batch to try, and they were so good that I am using the rest of my bananas to make more! They were good plain, but I topped them with some peanut butter spread made from the peanut flour, and it took them over the top! Thank you for this delicious recipe!!
