Banana oatmeal cookies

Making 3-ingredient banana oatmeal cookies is a quick and easy way to satisfy your sweet tooth with a healthier treat. These cookies are typically gluten-free and require only a few basic ingredients. Here's a simple recipe:
Yield: 3
Cost: $4


  • Bananas - 2 large, ripe bananas
  • Rolled oats - 1 cup (old-fashioned oats work best)
  • Chocolate chips
  • Raisins
  • Cinnamon
  • Nuts (e.g., chopped walnuts or almonds)


  • Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
  • Peel and mash the ripe bananas in a mixing bowl. You can use a fork or a potato masher for this. Ensure that the bananas are well mashed and mostly smooth.
  • Add the rolled oats to the mashed bananas. Stir to combine thoroughly. If you'd like, this is the point where you can add any optional add-ins for extra flavor. Common choices include a handful of chocolate chips, raisins, a dash of cinnamon, or some chopped nuts.
  • Let the mixture sit for a few minutes to allow the oats to absorb some of the moisture from the bananas. This will help bind the cookies together.
  • Scoop spoonfuls of the mixture onto the prepared baking sheet. You can use a cookie scoop or just drop them by spoonfuls. Use the back of the spoon to flatten and shape the cookies, as they won't spread much during baking.
  • Bake in the preheated oven for about 15-20 minutes or until the cookies are golden brown and set.
  • 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.

Tips and Variations

While the basic recipe is incredibly simple and delicious, here are some tips and variations to consider:


Banana Size: The size of your bananas can vary, so you may need to adjust the oat quantity accordingly. Start with 2-3 ripe bananas and add oats until you achieve the desired cookie dough consistency.


Texture: If you prefer cookies with more texture, use less ripe bananas, or add chopped nuts, dried fruits, or shredded coconut.


Sweetness: The sweetness of these cookies primarily comes from the ripe bananas. If you desire sweeter cookies, you can add a drizzle of honey or maple syrup to the dough or incorporate sweet add-ins like chocolate chips or dried fruit.


Spices: Experiment with spices like cinnamon, nutmeg, or vanilla extract to enhance the flavor profile of your cookies.

Nut Butter: For an extra dimension of flavor and creaminess, consider adding a tablespoon of nut butter (such as almond or peanut butter) to the cookie dough.

Protein Boost: If you’re looking to boost the protein content, you can incorporate a scoop of your favorite protein powder into the mix.

Storage: These cookies are best when consumed fresh. However, you can store them in an airtight container at room temperature for a day or two. For longer storage, keep them in the refrigerator for up to a week or freeze them for several months.

Tips for Perfect Banana Oatmeal Cookies

To achieve perfect banana oatmeal cookies, here are some tips to keep in mind:

Use Ripe Bananas: Ensure your bananas are ripe with brown spots on the peel. Overripe bananas are sweeter and will provide the best flavor and natural sweetness to your cookies.

Choose the Right Oats: Rolled oats, also known as old-fashioned oats, work best for this recipe. Instant oats or steel-cut oats will yield different textures and may not bind the cookies together as well.

Mash Bananas Thoroughly: Mash the bananas until they are mostly smooth with minimal lumps. This will help evenly distribute the banana flavor and moisture throughout the cookies.

Let the Mixture Rest: Allow the banana and oat mixture to sit for a few minutes before shaping the cookies. This resting time helps the oats absorb some moisture, resulting in a better cookie texture.

Add Optional Ingredients: Customize your cookies with optional add-ins like chocolate chips, raisins, nuts, or spices such as cinnamon or nutmeg for extra flavor and texture.

Use Parchment Paper: Line your baking sheet with parchment paper or lightly grease it to prevent the cookies from sticking to the pan.

Flatten the Cookies: These cookies don’t spread much during baking, so use the back of a spoon to flatten and shape them to your desired thickness before baking.

Keep an Eye on Baking Time: The baking time can vary depending on your oven and the thickness of your cookies. Bake until they are golden brown on the edges and set in the middle, typically around 15-20 minutes at 350°F (175°C).

Let Them Cool: Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack. They may be a bit fragile when hot but will firm up as they cool.


3-ingredient banana oatmeal cookies are a testament to the fact that delicious treats can be both simple and healthy. With just ripe bananas, rolled oats, and optional add-ins, you can create a delightful snack or dessert that satisfies your cravings without compromising your dietary goals.

Whether you’re following a specific diet, trying to reduce your sugar intake, or simply looking for a quick and easy baking project, these cookies are an excellent choice. They offer endless possibilities for customization, allowing you to tailor them to your taste preferences.

So, the next time you find yourself with overripe bananas on your kitchen counter, don’t hesitate to whip up a batch of these delightful cookies.
