What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. You probably have most of these pantry staples on hand, and they come together beautifully to create chewy banana oat cookies that feel both nourishing and indulgent.

• Ripe Bananas (2 medium, mashed) – The star ingredient, providing natural sweetness and moisture. Make sure they’re spotty and soft for best flavor.
• Old-Fashioned Rolled Oats (1 ½ cups / 135g) – Use rolled oats for that perfect chewy texture; quick oats tend to make the cookies too soft.
• All-Purpose Flour (½ cup / 60g) – Adds structure; you can swap with almond flour for a gluten-free option.
• Brown Sugar (⅓ cup / 70g) – Adds a hint of molasses flavor and deepens the chewiness.
• Unsalted Butter (6 tablespoons / 85g, softened) – Provides richness; I recommend using high-quality butter like Kerrygold for a buttery depth.
• Large Egg (1, room temperature) – Helps bind the dough together.
• Vanilla Extract (1 teaspoon) – Enhances the overall flavor.
• Baking Soda (½ teaspoon) – Gives a light lift to the cookies.
• Salt (¼ teaspoon) – Balances sweetness and brings out flavor nuances.
• Optional Mix-ins: chocolate chips, chopped walnuts, or shredded coconut to personalize your cookies.

For substitutions, use dairy-free butter and a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water) to make these vegan-friendly. Also, if you prefer a little crunch, swapping some oats for chopped nuts works wonders. In summer, feel free to toss in fresh or dried berries for a fruity twist.

Equipment Needed

To make these chewy banana oat cookies, you don’t need fancy gadgets—just straightforward kitchen tools that most home cooks already have. Here’s what I use and recommend:

• Mixing Bowls: Two bowls, one for wet ingredients and one for dry, keep things tidy.
• Measuring Cups and Spoons: Accuracy counts, so use standard measuring tools.
• Hand Mixer or Stand Mixer: Helpful but not necessary—mix by hand if you prefer.
• Baking Sheet: A rimmed baking sheet lined with parchment paper makes cleanup a breeze.
• Spatula: To fold ingredients without overmixing.
• Cooling Rack: Essential for letting cookies cool evenly without getting soggy.

If you don’t have a stand mixer, a sturdy wooden spoon and a bit of elbow grease work just fine. For budget-friendly options, silicone baking mats can replace parchment and are reusable. I’ve tested these cookies with various tools, and honestly, the results are forgiving, so no stress if your equipment is basic!

Preparation Method

1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat to prevent sticking.
2. Mash the bananas: In a large bowl, mash 2 medium ripe bananas with a fork until mostly smooth but still a bit chunky. This should take about 2-3 minutes.
3. Cream the butter and sugar: In a separate bowl, beat 6 tablespoons softened unsalted butter with ⅓ cup brown sugar until light and fluffy—about 2-3 minutes using a hand mixer or whisk by hand. This step adds air, making the cookies tender.
4. Add egg and vanilla: Beat in 1 large egg and 1 teaspoon vanilla extract until combined. If the mixture looks a bit curdled, that’s normal.
5. Combine wet and dry: Slowly add the mashed bananas to the butter mixture and stir until just combined.
6. Mix dry ingredients: In another bowl, whisk together 1 ½ cups rolled oats, ½ cup all-purpose flour, ½ teaspoon baking soda, and ¼ teaspoon salt.
7. Fold dry into wet: Add the dry ingredients to the wet ingredients in batches, folding gently with a spatula until just incorporated. Avoid overmixing to keep the cookies tender.
8. Add optional mix-ins: If using, fold in ½ cup chocolate chips, chopped nuts, or shredded coconut now.
9. Shape the cookies: Using a tablespoon or cookie scoop, drop dough onto the prepared baking sheet, spacing about 2 inches apart. Flatten slightly with the back of the spoon for even baking.
10. Bake: Place the baking sheet in the oven and bake for 12-15 minutes, until the edges are golden brown but the centers still look soft.
11. Cool: Remove from oven and let cookies rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
12. Enjoy: These cookies are best enjoyed within a day or two but can be stored for longer (see storage tips below).

Cooking Tips & Techniques

Getting these chewy banana oat cookies just right takes a little practice, but here are some tips I’ve picked up along the way to help you nail it every time:

• Banana ripeness matters: The riper, the better. Overripe bananas with lots of brown spots provide natural sweetness and moisture, making your cookies chewy and flavorful.
• Don’t overmix: Once you add the dry ingredients, mix just until combined. Overmixing activates gluten, which can make cookies tough rather than chewy.
• Butter temperature: Use softened butter, not melted. Softened butter creamed with sugar traps air, resulting in a lighter texture.
• Baking time watch: Take the cookies out when edges are golden but centers still look slightly underdone—they’ll firm up as they cool.
• Oats texture: Use old-fashioned rolled oats for the best chewiness. Instant oats make the texture too soft, and steel-cut oats won’t cook properly.
• Multitasking tip: While the cookies bake, you can quickly wash up your mixing bowls—makes life easier!

One time I baked these and left the dough in the fridge overnight—the flavors deepened and the cookies turned out even better. So if you want to prep ahead, chilling the dough is a great trick.

Variations & Adaptations

Want to switch things up? These chewy banana oat cookies are wonderfully adaptable to your tastes and dietary needs. Here are some variations I’ve tried and loved:

• Gluten-Free: Swap all-purpose flour for almond flour or a gluten-free all-purpose blend. Just be mindful that texture might be a little different—slightly denser but still delicious.
• Vegan Version: Use dairy-free butter and replace the egg with a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water, mixed and rested for 5 minutes).
• Flavor Boost: Add a teaspoon of cinnamon or a pinch of nutmeg for warm spice notes that complement the banana.
• Add-ins: Mix in ½ cup of dark chocolate chips, dried cranberries, chopped walnuts, or shredded coconut for extra texture and flavor.
• Lower Sugar: Reduce brown sugar to 2 tablespoons or omit entirely for a more naturally sweet cookie.

Personally, I once added a swirl of peanut butter into the dough before baking—talk about a nutty surprise! Feel free to experiment based on what you have on hand or your flavor preferences.

Serving & Storage Suggestions

These chewy banana oat cookies are best served at room temperature, where their softness shines. They pair beautifully with a glass of cold milk, a cup of tea, or your morning coffee. For a fun twist, try warming one for 10 seconds in the microwave—ooey-gooey goodness.

To store, place cooled cookies in an airtight container at room temperature for up to 3 days. If you want to keep them longer, pop them in the fridge for up to a week or freeze for up to 3 months. To freeze, layer parchment between cookies so they don’t stick together.

When reheating frozen cookies, let them thaw at room temperature or heat for 15-20 seconds in the microwave. The flavors often develop even more after a day, making leftovers taste just as good, if not better.
