Banana Oatmeal Cookies

Bananas. Oatmeal. Chocolate Chips. Yup, that is all you need in order to make these super simple healthy banana oatmeal cookies! This healthy cookies recipe is 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 this recipe because it’s made with 100% whole grains and naturally sweetened from banana. 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. Here is what you need:

  • 1 large banana
  • 1 cup ground oat flour
  • 3/4 cup rolled oats
  • 1/2 cup 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! So, pull out your Vitamix and place about 1.5 cups of rolled oats (quick cooking works too!) inside and blend on high until a fine powder has been made.


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.

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 gett 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.

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 eat the batter :D

Banana Oatmeal Cookies Add-In Ideas

The beauty of this recipe its implicity, however, if you’re feeling fancy you can totally add more add-ins that 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.
