Tips for best results

  • use over ripe fresh bananas, the more brown speckles on your banana, the better!
  • do not use bananas that have been frozen previously
  • these cookies don’t spread so make the spoonfuls the size you want the cookie to be
  • the cooking time is for 24 small tablespoon-ish-sized cookies, larger cookies may need a few extra minutes of baking time
  • this is a great recipe to freeze for meal prep-store in a freezer bag for up to 3 months

  1. These turned out very well. I made them into bars in a pan as opposed to cookies.
    I had an extra banana and also added the PB2, mini chocolate chips, and Quest protein powder. A little baking powder also helped them… No longer (3) ingredients but it helped start the tasty creation! Thanks for the recipe.🍪

  2. I had some strawberry oatmeal packets lying around so we used that, overripe bananas, and a handful of chocolate chips. The kids are the talk of the class during snack time. Second batch was regular oatmeal but we added peanutbutter. Thanks!

  3. Loved these healthy cookies. I’ve made them twice but i used craisins instead of chips second time around and used them as a quick on the go breakfast. I find storing them in the fridge for up to 3 days tastes as good as the day i made them.

  4. I’m not much of a baker so was very glad when I found this recipe. It was very easy to make. I baked for 17 mins. Taste like chocolate banana bread nice and chewy.

  5. Very easy to make. First batch we baked for 15 mins were just a bit underdone so the second tray we baked for 17 mins and came out with a better consistency. This may he our oven. Overall quick, tasty and much healthier cookie.
