3 ingredient healthy oatmeal ' cookies '

i’m calling these ‘cookies’ but really they are everything from a hearty breakfast to a filling snack or a healthy treat. these vegan healthy oatmeal cookies are more like a breakfast bar than a cookie really! i love the chewy texture and the sweetness from the banana! with only three ingredients, they are easy peasy to pull together – just ripe bananas, almond butter, and muesli.

since there are only three ingredients, i want to be sure all 3 are perfect. 

healthy oatmeal cookies - three ingredients

bananas – the bananas should be very ripe, but since there is no added sugar to this recipe, be sure that there is still a sweetness to the bananas. mash them well as they will be the main binder in this recipe.

let’s talk muesli shall we? you could use rolled oats for this recipe, but muesli is SO much better! what is it? a breakfast mix with oats, dry fruit, nuts, and/or seeds. you can make your own, but i really love  Nature ValleyTM Toasted Oats Muesli-Blueberry (and also the original) because of the sweet combination of blueberries, coconut, almonds, pumpkin seeds, and of course oats. it ALSO means that when i’m at the store i can grab ONE thing vs a bunch of different ingredients, and i already know it will have a great balance of flavors.

almond butter – i’m picky about my almond butter. i have tried lots of them and LOVE crazy richard’s. it has a really strong roasted almond flavor and NO OTHER ingredients! it’s pure almond butter – but its the best i have ever tasted. i highly recommend getting some

mash the bananas, mix in the muesli, add the almond butter and your batter is ready in minutes. i usually roll about 2 inch balls and bake them on a silpat. the sugars in the banana brown the bottom nicely and the top gets crunchy while the inside stays soft and chewy. they do not need to be spaced out on your cookie sheet as they will not expand. shape them as you would like them to be – in the picture below they are rolled into balls, but i usually flatten them out a bit so they are more like a dome. sometimes I will even form them into rectangles so they are more of a breakfast ‘bar’… whatever you do – they will turn out good, you just may need to adjust the baking time a bit.

  1. Yum! These look great and I think they’d be so nice to have on hand for a quick breakfast or snack!

  2. YUM! I have been eating muesli lately because it;s been too hot for oatmeal – but now I’d love a cookie for breakfast instead

    • It is SO good! I have made a bunch of different versions of this lately! Yesterday I made them with raw oats, coconut, cookie butter (my son has a nut allergy) and bananas. they were SO good!

  3. Do you think you could substitute nature valley granola with raisins for the muesl or is it the same thing?

    • I don’t think so…. the granola is baked and in clusters so it would not mix or bake correctly. the muesli is raw oats and seeds without any binder. however, if you pulsed it in the food processor to break it down a bit, that may work. when i don’t have the muesli i often just use plain rolled raw oats and raisins so that would be your best bet!

  4. These look incredible! Can’t wait to try them!
