Hi there! It’s been freezing cold here in Ohio (seriously, like polar vortex cold). So, my five-year-old daughter and I have been spending a lot of time indoors trying to entertain ourselves. I don’t know about you, but I go stir crazy when I’m in the house for too long.

After dressing all the dolls, playing with all the horses, and dancing to Tangled music we decided to do some baking. Warm oatmeal cookies sounded amazing to me. I looked on Pinterest for a bit and found that most recipes included a lot of sugar (either cane sugar, honey, or maple syrup). I really wanted a healthy, sugar-free snack as opposed to a sugary dessert. So, after looking in our pantry and seeing that we had bananas and rolled oats we decided to make super simple 3 ingredient healthy oatmeal banana cookies.

A Bit About Oats

If you are buying oats for this recipe and are concerned about gluten like I am, just make sure that the bag or box states that they are certified gluten-free.

But aren’t oats always gluten free? Yes and No.

Pure oats are gluten-free. They are safe for most people with gluten-intolerance. The problem with oats in gluten-free eating is contamination. Most commercial oats are processed in facilities that also process wheat, barley, and rye. The gluten in these ingredients can contaminate oats.

Contamination can also happen in the field when they are grown next to fields of wheat. So, it’s best to completely avoid conventionally grown and processed oats. There are many brands of gluten-free oats. My favorites are Trader Joe’s Gluten Free Rolled Oats or Bob’s Red Mill Gluten Free Organic Old Fashioned Rolled Oats.

So, what’s the third ingredient? The fun part is that this is up to you. We used raisins because that’s what we had in our pantry and I love oatmeal raisin everything. You can replace raisins with chocolate chips, another dried fruit, nuts. Whatever you like!

These are so super easy to make with your kids. My daughter could probably do this on her own other than putting them in and taking them out of the oven.

We just tossed the ingredients into our kitchen-aid mixer (I always look for reasons to use my kitchen-aid mixer…love it!). My daughter then used a cookie dough scoop to measure and place tablespoonish size balls of the mixture onto parchment paper. I placed them into the oven for 15 minutes, waited for them to cool, and then yum!

These 3 ingredient healthy oatmeal banana cookies are great for a snack or with your breakfast. I love them with coffee, but then again I love coffee with everything 🙂

My daughter loves these and I love that she loves them because they are healthy and a great replacement for sugary cookies and granola bars. They are also a lot less expensive than buying a box of already made snacks.

So, gather your ingredients and give this recipe a try!

  • 1 cup gluten-free rolled oats
  • 2 medium bananas
  • 25 grams raisins (add as many as you’d like)


  1. Preheat oven to 350°F (180oC) and line a large cookie sheet with parchment paper.
  2. Mash bananas in a large bowl with a fork. Or toss them into your KitchenAid to mix. Add in the oats and mix well to combine. Fold in the raisins (or whichever add-in you choose).

  3. Scoop the mixture onto your cookie sheet using a cookie scoop or spoon. We used about one tablespoon per cookie.

  4. Bake for 15-20 minutes until the cookies are golden on top and just set to the touch. Remove from the oven and allow to cool for a few minutes before enjoying.

Recipe Notes

These are also great cold/refrigerated.

If using chocolate chips I would recommend Enjoy Life Semi-sweet Chocolate Mini Chips. They are dairy, gluten, nut, and soy free. Or, you can use my recipe for Easy Homemade Keto Dairy Free Chocolate.
