Add-In Options

Add in dairy-free chocolate chips or chopped dark chocolate for a treat! Raisins or walnuts are also yummy, or any of the above, or ALL OF THE ABOVE! Why not, right?

I also like adding a pinch of sea salt and a dash of pure vanilla extract for extra flavour. You can also add a pinch of cinnamon if you like!

Healthiest Option

If you prefer to go a little healthier, you can leave out the maple syrup and chocolate chips. They’ll just be a tad less sweet but they’ll still be tasty and satisfying. You can always add a few pinches of stevia if you want them to be a bit sweeter.

Low-Fat Option

If you want to reduce the fat, replace the peanut butter with powdered peanut butter. You can either mix the powdered peanut butter with water first to create “peanut butter” or just add it in as is. If you just add the powder straight into the dough, you may need a little extra banana or applesauce to for extra moisture.

You can’t really go wrong with these so don’t worry too much about the exact amounts. As long as it has a thick cookie dough consistency before baking you should be good to go.

Please keep in mind since these have very minimal ingredients and no flour, they’re quite chewy and have more of a muffin-like texture. I love them though and they’re one of my favourite go-to treats.

They make an awesome snack, especially before a workout, or after dinner…okay, anytime at all, and I guarantee they’ll satisfy a craving for something sweet!

My favourite way to make them with with natural peanut butter, extra ripe bananas and the added pure maple syrupvanilla and chocolate chips. If I’m gonna eat cookies, I wanna eat a cookie, ya know what I mean?

Natural vs. Processed Peanut Butter

If you’re still using processed peanut butter in your home, it’s about time you switch over to natural peanut butter. It’s a simply switch you can make on your journey to a healthier lifestyle.

If you’re unfamiliar with natural peanut butter, you’ll notice that when you bring it home from the store, the oil has most likely separated. No worries, just stir it in using spoon or knife or store it upside down to let it mix up on it’s own.

Natural peanut butter should have just one or maybe two ingredients: peanuts and salt. The ingredients in processed peanut butters will vary by brand by they all contain hydrogenated oils and added sugar. Because of the added hydrogenated oils, processed peanut butter has a completely different consistency than natural peanut butter.

I used to love Kraft and JIF Peanut Butter when I was a kid but as an adult the consistency and flavour just seem bizarre to me. Ditch the processed peanut butter and the trans fats and refined sugar it comes with and make the switch! You can even easily make your own peanut butter if you have a high-powered blender or good food processor.

These flourless peanut butter banana oatmeal cookies require just 3 basic ingredients to make then you can have some fun with add-ins like chocolate chips! These cookies are a wholesome treat you can enjoy anytime of the day as a healthy way to satisfy your sweet tooth.



Optional Flavour Enhancers and Add-Ins


  1. Pre-heat oven to 350 F.
  2. Mash the bananas in a bowl with a fork until they form a thick, smooth paste.
  3. Add the rest of the ingredients and mix until everything is combined into a dough.
  4. Drop 16 spoonfuls onto a cookie sheet, shaping each spoonful into a cookie shape. The cookies will not change shape during baking, so make sure you create the cookie shape you want beforehand. You can make them larger and flatter or keep them as more of a haystack-style.
  5. Bake for 15 minutes. They should be firm and slightly browned when done.
  6. Let cool completely before storing. Store in a sealed container at room temperature for up to 3 days, in the fridge for up to 1 week or freeze for up to 3 months.


The maple syrup, vanilla, salt and chocolate chips are all optional. The most basic version of this recipe is just the oats, banana and peanut butter. Feel free to add in any or all of the options to suit your taste preference. Walnuts, coconut, raisins, cranberries or any other nuts, seeds, or dried fruit work well.

Rolled or old fashioned oats are totally fine to use in this recipe but quick oats just hold together a little better since they’re finer. I usually just use rolled oats because that’s what I tend to have on hand.

These have a soft, baked oatmeal-like texture and do not get hard or crunchy. Made with just banana, peanut butter and oats, they are a healthy snack or treat, not a decadent dessert. Add the extras, especially chocolate chips, to make them sweeter and more of a treat.
