All it takes are 3 simple ingredients to make these naturally sweetened Banana Oatmeal Cookies.
Plus, this banana cookies are kid-friendly, gluten free, and made in under 20 minutes!
These healthy cookies are a close relative to our vegan peanut butter banana cookies, but even more simple because they are made without a flax egg.
3 Ingredient Banana Oatmeal Cookies
We love these banana oatmeal cookies because they’re made with 100% whole grains and naturally sweetened from bananas.
You could even make this a 2 ingredient cookie by omitting the chocolate chips (not recommended :P). That means, these cookies are vegan, gluten free, and refined sugar free.
What You Need
- banana
- ground oat flour
- rolled oats
- chocolate chips
You’ll see that there are 4 ingredients listed above, but you can actually make your own ground oat flour at home by grinding your oats into a flour. This is such an easy trick and believe me, a lot cheaper too!
homemade ground oat flour
Place around 1.5 cups of rolled oats (quick-cooking works too!) inside a high-speed blender and blend on high until a fine powder has been made.
Storage: store ground oat flour in an airtight container in a cool, dark place for up to 6 months.
Instructions
Once you’ve got your ground oat flour made, it’s time to mash your banana. We recommend using a ripe banana so that it’s a little bit on the sweeter side. Use a fork to mash your banana as best you can so that there are little to no chunks in it.
Mix it with the oat flour and rolled oats until combined. You’ll notice that this batter is a little bit wetter compared to traditional cookie dough. This is A-okay! Finally, add in your chocolate chips and give your batter one last stir.
Make the Cookies
When forming your cookies on the cookie sheet it is important to note that these cookies will not expand. We opted not to use an egg or egg replacement and did not use a leavening agent, either.
We did this specifically for the simplicity aspect of these banana oatmeal cookies. With that said, you’ll need to form a cookie shape with your hands and we recommend get your hands a little bit wet so that the dough doesn’t stick to you.
Lightly flatten your dough into the shape of a cookie and then add more chocolate chips if desired.
Bake Time
Your banana oatmeal cookies only need about 8 minutes in the oven before they’re ready to eat! If you can’t wait that long, don’t worry! These cookies are 100% vegan and you can safely eat the batter.
Banana Oatmeal Cookies Add-In Ideas
The beauty of this recipe its simplicity, however, if you’re feeling fancy you can totally add more add-ins than we did! Here are some suggestions to switch up the flavors a little bit:
- spices: cinnamon, homemade chai spice, vanilla extract, etc.
- dried fruit: cranberries, raisins, coconut, etc.
- seeds: flax, chia, pumpkin, etc.
Storage
Let cookies cool completely. Then, transfer them into an airtight container and store in the fridge for up to 5 days.
Freezer Instructions
- Let cookies cool completely.
- Transfer them back onto a baking sheet and place in the freezer for 30 minutes.
- Once they are partially frozen, transfer them into a gallon-size plastic bag and freeze for up to 3 months.

They went fast! Next time I’m going to try some cinnamon and maybe a spoon full of maple syrup for more flavor.
Could you sub almond flour for oat flour?
Hi! Unfortunately, we don’t recommend this sub.
My son loves it which is a big win. I don’t like banana chunks so I put my bananas in a blender so they are smooth and creamy.
Really nice recipe, and the page design is really good. I gonna try this 🙂 Thnks
Can we add an egg for extra protein?
Hey Bonnie! I’m sure you can, but I would reduce the liquid elsewhere!
This batch of cookies look perfect in every way–easy, soft, sweet, and loaded with chocolate chips! Can’t beat anything easier than this. I might have to include this recipe if I decide to attempt a full day of eating with five-ingredient-or-less meals!
