3 Ingredient Oat Cookies

If you’re a fan of quick and easy recipes that still deliver a burst of flavor, then 3-ingredient oat cookies might just become your new favorite treat. These cookies are not only simple to make but also a healthier alternative to many store-bought options. With just a handful of ingredients, you can whip up a batch of these delightful treats that are perfect for a snack, dessert, or even breakfast. Let’s dive into the simplicity and scrumptiousness of 3-ingredient oat cookies.


  1. Oats: The star ingredient of these cookies is oats, and not just any oats will do. Old-fashioned rolled oats work best for this recipe, as they provide a hearty and chewy texture to the cookies. Oats are not only a great source of fiber but also contain essential nutrients like iron, magnesium, and antioxidants, making these cookies a healthier choice.
  2. Bananas: The natural sweetness and binding agent in these cookies come from ripe bananas. The riper the bananas, the sweeter your cookies will be. Bananas add a delightful flavor while contributing potassium, vitamin C, and other beneficial nutrients. This also means you can enjoy a sweet treat without the need for refined sugars.
  3. Add-ins of your choice: While the base recipe requires only oats and bananas, you have the flexibility to customize your cookies by adding optional ingredients. Popular choices include chocolate chips, nuts, dried fruit, or a dash of cinnamon. These add-ins not only enhance the flavor but also give your cookies a unique twist.


  1. Preheat your oven: Start by preheating your oven to 350°F (180°C) and line a baking sheet with parchment paper. This ensures that your cookies won’t stick and makes for easy cleanup.
  2. Mash the bananas: In a bowl, mash the ripe bananas with a fork until they form a smooth consistency. The bananas act as a natural sweetener and binder for the oats.
  3. Mix in the oats: Add the rolled oats to the mashed bananas and stir until well combined. This will create a thick dough-like mixture.
  4. Add optional ingredients: If you choose to include additional ingredients, fold them into the dough. Whether it’s chocolate chips, nuts, or dried fruit, these add-ins contribute extra flavor and texture.
  5. Form cookies: Use a spoon to drop rounded portions of the dough onto the prepared baking sheet. Flatten each portion slightly to form a cookie shape.
  6. Bake: Bake the cookies in the preheated oven for approximately 12-15 minutes or until the edges turn golden brown. Keep an eye on them to prevent overcooking.
  7. Cool and enjoy: Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack. Once cooled, indulge in these delightful 3-ingredient oat cookies!

In just a few easy steps, you can create a batch of wholesome, delicious oat cookies with only three main ingredients. The simplicity of this recipe makes it perfect for those looking for a quick and healthy treat that doesn’t compromise on taste. Experiment with different add-ins to tailor these cookies to your preferences, and enjoy a guilt-free snack or dessert that’s sure to become a household favorite.

Variations and Tips for Perfect 3-Ingredient Oat Cookies:

1. Flavorful Add-ins:

While the basic recipe is fantastic, consider experimenting with various add-ins to elevate the flavor profile. Try incorporating shredded coconut, chia seeds, or a drizzle of honey for added sweetness. For a protein boost, mix in a scoop of your favorite protein powder or nut butter.

2. Customize with Spices:

Enhance the aroma and taste of your cookies by adding a pinch of your favorite spices. Cinnamon, nutmeg, or a hint of vanilla extract can provide a warm and comforting undertone to the cookies, making them even more irresistible.

3. Dietary Modifications:

This recipe can easily be adapted to suit different dietary preferences. For a gluten-free version, ensure your oats are certified gluten-free. Those following a vegan diet can use plant-based protein powder or enjoy the cookies as is, as they are naturally dairy-free.

4. Texture Play:

Play around with the texture of your cookies by adjusting the ratio of oats to bananas. If you prefer a chewier cookie, reduce the amount of oats, and for a firmer texture, add a bit more oats to the mix.

5. Shape and Size:

Get creative with the shape and size of your cookies. Use cookie cutters for fun shapes or make smaller, bite-sized versions. This can be especially appealing for kids, and it adds a touch of whimsy to your baking.

6. Storage and Longevity:

These cookies are best enjoyed fresh, but you can store them in an airtight container for up to a week. If you want to extend their shelf life, consider freezing them. Simply place the cookies in a single layer on a baking sheet, freeze until solid, and then transfer them to a freezer bag. When a cookie craving strikes, grab a few and let them thaw at room temperature.

7. Pairing Suggestions:

Enjoy your 3-ingredient oat cookies with a cup of hot tea, a glass of milk, or your favorite nut milk alternative. The simplicity of the cookies makes them a versatile companion to a variety of beverages.

8. Gift-Worthy Treats:

Package these delightful cookies in a decorative box or jar, tie it with a ribbon, and you have a thoughtful homemade gift. These treats make for a lovely present during holidays or special occasions, showcasing your baking prowess and consideration for others.

3-ingredient oat cookies offer not just simplicity but a canvas for your culinary creativity. Whether you’re a seasoned baker or a novice in the kitchen, these cookies are a delightful and healthy go-to option. So, grab those bananas and oats, experiment with flavors, and treat yourself to a delicious and guilt-free homemade snack.
