Peanut Butter, Banana and Oatmeal are all you need for these chewy 3 Ingredient Banana Oat Cookies. They’re gluten-free, vegan, just overall healthy, and extremely easy to put together. Perfect for a healthy dessert, on-the-go snack or breakfast.


They’re not only soft and chewy, but absolutely delicious! I might just bulk-bake these again and pop them in the freezer so I have something when the cravings hit.


Thinking back, this is probably the first time I made a recipe without going through my endless to-do list or seeing any Instagram post that I couldn't help but try out. The source of inspiration for this were the PB Powder Oatmeal Cookies that I made recently.


I spent ages trying to find a recipe to base that off of, and everything that popped up had mashed bananas in it. But I thought mashed bananas + oatmeal deserved their own cookie recipe.

      I’ve made this recipe with just bananas and instant sugar free apple/cinnamon oatmeal and chopped nuts - It works. I’ve made it many times
