Ingredients for Banana Oatmeal Cookie Perfection
- Ripe Bananas: (2 medium) The star of the show! Overripe bananas are essential for sweetness and moisture. The riper, the better! As bananas ripen, their starch converts to sugar, intensifying the flavor and sweetness. If you only have slightly ripe bananas, consider adding a touch more brown sugar to the recipe.
- Rolled Oats: (1 ½ cups) Use old-fashioned rolled oats, not instant. Rolled oats provide a chewy texture and nutty flavor. They also contribute fiber, making these cookies a bit more wholesome. Quick oats can be used in a pinch, but the texture will be slightly different.
- All-Purpose Flour: (1 cup) Provides structure. For a gluten-free version, substitute with a 1:1 gluten-free all-purpose flour blend.
- Brown Sugar: (½ cup, packed) Adds moisture and a caramel-like flavor. Light or dark brown sugar can be used.
- Granulated Sugar: (¼ cup) For sweetness and crisp edges.
- Butter: (½ cup, softened) Adds richness and flavor. Unsalted butter is recommended to control the salt level. If using salted butter, reduce the amount of added salt slightly.
- Egg: (1 large) Binds the ingredients together. Flax eggs can be used as a vegan substitute (1 tablespoon ground flaxseed meal mixed with 3 tablespoons water, let sit for 5 minutes).
- Vanilla Extract: (1 teaspoon) Enhances the flavor. Use pure vanilla extract for the best results.
- Baking Soda: (1 teaspoon) Helps the cookies rise.
- Cinnamon: (½ teaspoon) Adds warmth and spice.
- Salt: (¼ teaspoon) Balances the sweetness.
- Optional Add-ins: Chocolate chips, walnuts, raisins, or shredded coconut.
Remember to always use fresh baking soda and baking powder for the best results. These are leavening agents that help the cookies rise, and their effectiveness diminishes over time. Also, properly measuring your flour is key to achieving the right consistency. Spoon the flour into your measuring cup and level it off with a knife, rather than scooping it directly from the bag. This prevents the flour from being too densely packed, which can result in dry cookies.
Expert Tips for the Best Banana Oatmeal Cookies

- Don’t overmix the dough: Overmixing develops the gluten in the flour, which can result in tough cookies. Mix until just combined.
- Chill the dough: For even chewier cookies, chill the dough for at least 30 minutes before baking. This also helps prevent the cookies from spreading too thin.
- Use a cookie scoop: For uniform cookies that bake evenly, use a cookie scoop to portion the dough.
- Don’t overcrowd the baking sheet: Give the cookies enough space to spread without touching each other.
- Underbake slightly: For the chewiest texture, slightly underbake the cookies. They will continue to set up as they cool.
- Experiment with flavors: Add a pinch of nutmeg or cardamom for a warm, spiced flavor. Consider adding a tablespoon of peanut butter for a nutty twist.
These cookies are best enjoyed fresh, but they can also be stored for later. Allow the cookies to cool completely on a wire rack before storing them in an airtight container. To keep them extra soft, add a slice of bread to the container. The bread will absorb excess moisture, keeping the cookies from drying out.
Storage & Substitutions for Chewy Banana Oatmeal Cookies
Storage: Store cooled cookies in an airtight container at room temperature for up to 3 days. For longer storage, freeze the cookies for up to 2 months. Thaw at room temperature before serving.
Substitutions:
- Gluten-Free: Use a 1:1 gluten-free all-purpose flour blend.
- Vegan: Substitute the butter with vegan butter or coconut oil, and use a flax egg (1 tablespoon ground flaxseed meal mixed with 3 tablespoons water, let sit for 5 minutes) in place of the egg.
- Sugar-Free: Use a sugar substitute like erythritol or stevia. Adjust the amount according to the package directions.
- Nut-Free: Omit any nuts from the recipe.
Want to add more flavor? Try using mashed sweet potatoes instead of banana for a similar texture and sweetness. Another great addition is unsweetened applesauce, which also provides moisture and a hint of natural sweetness. Consider using brown butter for an extra nutty and complex flavor. Brown butter is simply butter that has been cooked until the milk solids turn golden brown and have a nutty aroma.
Frequently Asked Questions (FAQ) about Banana Oatmeal Cookies
Can I use instant oats instead of rolled oats?
While rolled oats are preferred for their chewy texture, you can use instant oats in a pinch. However, the texture of the cookies will be slightly different, resulting in a less chewy and more cake-like consistency.
Can I freeze the cookie dough?
Yes, you can freeze the cookie dough. Scoop the dough into individual balls and place them on a baking sheet lined with parchment paper. Freeze for about 30 minutes, or until solid. Then, transfer the frozen dough balls to a freezer-safe bag or container. Bake directly from frozen, adding a few extra minutes to the baking time.
How do I prevent the cookies from spreading too thin?
Chilling the dough for at least 30 minutes before baking helps prevent the cookies from spreading too thin. Also, make sure your baking sheet is not greased, as this can encourage spreading. Using parchment paper or a silicone baking mat is recommended.
Can I add chocolate chips to these cookies?
Absolutely! Chocolate chips are a delicious addition to these cookies. Add about ½ cup of chocolate chips to the dough before baking. You can use milk chocolate, dark chocolate, or semi-sweet chocolate chips, depending on your preference.
How do I make these cookies more healthy?
To make these cookies healthier, you can reduce the amount of sugar, substitute some of the all-purpose flour with whole wheat flour, and add ingredients like chia seeds or flax seeds for extra fiber and nutrients. Using unsweetened applesauce in place of some of the butter can also help reduce the fat content.
Why are my cookies dry?
Dry cookies can be caused by over-measuring the flour or over-baking. Make sure to measure the flour correctly by spooning it into the measuring cup and leveling it off. Also, keep a close eye on the cookies while they are baking and remove them from the oven as soon as they are lightly golden brown.
Can I use frozen bananas?
Yes, you can use frozen bananas. Make sure to thaw them completely and drain any excess liquid before mashing and adding them to the dough. Thawed bananas tend to be even softer and sweeter, which can enhance the flavor and texture of the cookies.
