1.81 g






Makes: 8-12 cookies depending on preferred size

  • 2 ripe bananas, mashed
  • 1 cup rolled oats
  • 1/4 cup chocolate chips, raisins, or chopped nuts (optional)


  • Preheat Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
  • Mix Ingredients: In a mixing bowl, mash the ripe bananas using a fork until smooth. Add the rolled oats to the mashed bananas and mix well until all the oats are coated and a dough forms. If desired, fold in chocolate chips, raisins, or chopped nuts for extra flavor.
  • Form Cookies: Using a spoon or your hands, scoop out about 1-2 tablespoons of the oat and banana mixture and shape it into a small cookie. Place the cookies onto the prepared baking sheet, leaving a little space between each one.
  • Bake: Place the baking sheet in the preheated oven and bake the cookies for 12-15 minutes, or until the edges are golden brown and the cookies are set.
  • Cool: Remove the cookies from the oven and let them cool on the baking sheet for a few minutes. Then, transfer them to a wire rack to cool completely.
  • Enjoy: Once the cookies have cooled, enjoy them as a healthy and delicious snack or breakfast option. 

Note: This recipe is incredibly versatile, and you can customize it to your liking by adding different mix-ins such as dried fruit, nuts, seeds, or spices like cinnamon or nutmeg. Feel free to experiment with flavors and textures to create your perfect oatmeal and banana cookies!


Store any leftover cookies in an airtight container at room temperature for up to 3 days. You can also freeze the cookies by individually wrapping them in plastic wrap or aluminum foil and placing them in an airtight freezer bag for up to 2 months.

Our Story

As someone who loves making tasty and healthy snacks, I often find myself looking for simple recipes that hit the spot. One day, I was craving something yummy and wholesome, but I didn't want to spend ages in the kitchen.

I figured, why not make some cookies? But I wanted them to be easy, with ingredients I already had on hand. That's when I thought about bananas and oatmeal—both super basic, but also super good for you.

I mashed up some ripe bananas, mixed in some oatmeal, and added a sprinkle of cinnamon for flavor. After a bit of trial and error, I nailed down the perfect recipe for these three-ingredient banana oatmeal cookies. They're chewy, sweet, and just downright delicious.

Now, whenever I need a quick snack or a little pick-me-up, I whip up a batch of these cookies. They're so easy to make and they taste amazing. I hope you give them a try—they might just become your new favorite snack too!
