Ingredients You’ll Need

1 ½ cups (186g) all-purpose flour: This provides the base structure for your cookies. If you want a gluten-free version, almond flour works well as a substitute.
1 teaspoon ground cinnamon: Adds a warm, cozy flavor and aroma—perfectly complements the sweetness of bananas.
½ teaspoon salt: Enhances the overall flavor. Don’t skip this step!
1 teaspoon baking soda: Helps the cookies rise and become light and fluffy.
½ cup unsalted butter (softened): The fat in butter adds richness and helps achieve a tender texture. Make sure it’s at room temperature for easy mixing!
½ cup (100g) granulated sugar: Balances the flavors and contributes to the cookie’s sweetness.
1 cup (200g) packed brown sugar: Gives a deeper sweetness and moisture, making for chewier cookies.
2 medium overripe bananas (mashed, approximately 1 cup): These add natural sweetness and moisture. The riper, the better!
1 large egg: Binds the ingredients together while adding richness.
1 teaspoon vanilla extract: Infuses the cookies with a rich, sweet flavor.
3 ¼ cups quick cooking oats: They provide texture and heartiness. Rolled oats can work too, but adjust baking time slightly for softer cookies.
1 ½ cups chocolate chips (optional): For a decadent touch! Use semi-sweet, dark, or even white chocolate based on your preference.

How to Make Banana Oatmeal Cookies

Preheat the Oven: Start by setting your oven to 350°F (175°C). Line your cookie sheets with parchment paper or silicone mats to prevent sticking.
Whisk Dry Ingredients: In a medium bowl, whisk together 1 ½ cups all-purpose flour, 1 teaspoon ground cinnamon, ½ teaspoon salt, and 1 teaspoon baking soda. This creates an even blend of dry ingredients. Set it aside while you mix the wet ingredients.
Cream Butter and Sugars: In the bowl of a stand mixer, or using a large bowl and electric hand mixer, cream together ½ cup softened unsalted butter, ½ cup granulated sugar, and 1 cup packed brown sugar on medium speed for about 3 minutes, until fluffy.
Incorporate Wet Ingredients: Add 2 medium mashed bananas, 1 large egg, and 1 teaspoon vanilla extract to the mixture, mixing until just blended. Don’t worry if the mixture is a little lumpy; this adds character to the cookies!
Combine Dry and Wet Ingredients: Gradually mix in the flour mixture, ensuring not to overmix. Once combined, fold in 3 ¼ cups quick cooking oats and 1 ½ cups chocolate chips, if you’re using them. This is where the magic happens!
Scoop the Dough: Using a cookie scoop or two tablespoons, drop dough balls about 2 inches apart onto your prepared cookie sheets.
Bake: Pop the cookies in the oven and bake them for about 10-15 minutes, or until they’re light golden and slightly set. You’ll know they’re ready when the tops no longer look glossy.
Cooling Time: Let them cool on the baking sheets for 3-5 minutes, then transfer them to a wire rack to cool completely. The waiting might be the hardest part!

Storing & Reheating

To store your cookies, place them in an airtight container at room temperature where they’ll stay fresh for about a week. If you’d like to keep them longer, store in the refrigerator for up to two weeks, ensuring they’re in a tightly sealed container to maintain freshness. For longer storage, freeze your cookies in a single layer, then transfer them to a freezer-safe bag for up to three months. When you’re ready to enjoy, simply reheat them in the oven at 350°F for a few minutes. The texture may slightly change upon freezing, but a quick warm-up will revive that delightful softness.

Chef’s Helpful Tips

Make sure your bananas are very ripe—they should be covered in brown spots or even black for the sweetest flavor.
If your dough seems too wet, adding a tablespoon more of flour can help resolve that.
For the chewiest cookies, don’t overmix when adding the dry ingredients to the wet—you want everything just combined.
You can easily mix in nuts or dried fruit for extra texture and flavor.
If you like a hint of saltiness, sprinkle a touch of sea salt on top of the cookies before baking.

There’s something truly special about Banana Oatmeal Cookies. They effortlessly combine comfort and flavor, and they’re an excellent way to use up those overripe bananas sitting on your counter. These cookies are easy to whip up and almost always disappear in a flash once they hit the table. I encourage you to take a moment, gather your ingredients, and give this recipe a try. You’ll love the warmth and nostalgia that comes with every chewy bite. Enjoy the process and don’t hesitate to make these cookies your own!

Recipe FAQs

Can I use old-fashioned oats instead of quick cooking oats?

Yes, you can use old-fashioned oats! However, the cookies may have a slightly different texture and might require an adjustment in baking time. Old-fashioned oats provide a heartier chew, so keep an eye on them while they bake.

How can I make these cookies healthier?

You can easily make these cookies healthier by substituting half of the all-purpose flour with whole wheat flour. You can also reduce the sugar slightly or use natural sweeteners like honey or maple syrup. Additionally, include nuts or seeds for an extra nutritional boost!

Are these cookies suitable for freezing?

Absolutely! They freeze really well. Just make sure they’re in a single layer on a baking sheet until solid, then transfer them to a freezer-safe container or zip-top bag. They’ll stay fresh for up to three months. Just thaw and enjoy!

How do I know when my cookies are done?

The cookies are done when they are light golden brown and no longer glossy on top. Remember that they will continue to cook a bit after being removed from the oven, so it’s best to err on the side of slightly underbaked for that perfect chewy texture!
