These banana oat cookies are soft, naturally sweet, and have a warm cinnamon swirl that feels like a hug. Using sprouted oats adds a wholesome touch. Great for a quick breakfast or afternoon snack!
Introduction
I first made these banana oat cookies on a chilly afternoon when I wanted something sweet but wholesome. Using sprouted oat flour adds a lovely nutty flavor and extra nutrition that regular oats don’t have. I love how the cinnamon swirl gives each bite a warm, comforting note without overpowering the natural sweetness of the bananas. The trick I learned is to mash the bananas until super smooth so the cookies stay soft and moist. These cookies are perfect when you need a quick breakfast or a snack that feels like a little treat. They’re easy to whip up and don’t require any refined sugar, which makes me feel good about indulging. Honestly, my first batch was a bit crumbly, but once I got the oat flour ratio right, they came out perfectly tender and chewy. I think you’ll love how they balance sweet, soft, and lightly spiced all at once!
What You'll Need
Approximately 12 cookies, 4 servings
- 2 ripe bananas, mashed
- 1 1/2 cups sprouted oat flour
- 1 cup rolled oats
- 1/4 cup maple syrup
- 1/4 cup coconut oil, melted
- 1 teaspoon vanilla extract
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon
- 1/2 teaspoon salt
How To Do It
Step 1
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. This step ensures your cookies bake evenly and don’t stick. Preheating is crucial because it activates the baking powder right away, giving your cookies a nice lift. Avoid skipping this or your cookies might turn out dense or unevenly cooked.
⏱ Time: 10 minutes
✓ Doneness: Oven fully preheated; parchment paper flat and ready
Step 2
In a large bowl, mash the ripe bananas thoroughly until smooth with no large lumps. This is key for moisture and sweetness. If the bananas aren’t ripe enough, the cookies won’t be as flavorful or soft. Using ripe bananas also means you can cut down on added sweeteners.
⏱ Time: 5 minutes
✓ Doneness: Banana mash is creamy and uniform in texture
Step 3
Add the melted coconut oil, maple syrup, and vanilla extract to the mashed bananas. Stir well until everything is combined. The coconut oil adds richness and keeps the cookies moist, while the maple syrup brings natural sweetness. Mixing these liquids thoroughly helps your batter come together smoothly.
⏱ Time: 3 minutes
✓ Doneness: Mixture looks homogenous and glossy
Step 4
In a separate bowl, whisk together the sprouted oat flour, rolled oats, baking powder, cinnamon, and salt. This dry mix provides structure and flavor. Whisking helps distribute the baking powder evenly, so the cookies rise uniformly. Don’t skip this step or you risk uneven texture.
⏱ Time: 5 minutes
✓ Doneness: Dry ingredients are well combined with no clumps
Step 5
Gradually add the dry ingredients into the wet banana mixture, stirring gently until just combined. Overmixing can make cookies tough, so stop as soon as you don’t see flour streaks. The dough will be sticky and thick — that’s perfect for soft cookies.
⏱ Time: 4 minutes
✓ Doneness: Dough is uniform but still slightly sticky
Step 6
Spoon the cookie dough onto the prepared baking sheet in rounded tablespoons. Leave about 2 inches between cookies as they will spread slightly. If you want a more pronounced cinnamon swirl, sprinkle a little extra cinnamon on top of each cookie before baking.
⏱ Time: 5 minutes
✓ Doneness: Cookie mounds evenly spaced and cinnamon sprinkled
Step 7
Bake the cookies for 18-20 minutes until the edges are golden and the centers feel set but still soft. Avoid overbaking, or the cookies will dry out. The warm cinnamon aroma is a good indicator they’re close to done.
⏱ Time: 20 minutes
✓ Doneness: Edges lightly browned; centers no longer jiggly
Step 8
Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. This resting helps them firm up without becoming hard. Handling too soon can cause breakage or crumbling.
⏱ Time: 10 minutes
✓ Doneness: Cookies hold shape when gently lifted
Step 9
Once cooled, enjoy immediately or store in an airtight container at room temperature for up to 3 days. These cookies also freeze well. If you freeze them, thaw at room temperature before eating for the best texture.
⏱ Time: N/A
✓ Doneness: Cookies remain soft and flavorful after storage
Pro Tips
Use very ripe bananas for maximum sweetness and moisture.
Ripe bananas break down more easily, providing natural sugars and moisture that keep the cookies soft and flavorful. Using underripe bananas can lead to dry, bland cookies as they have less sugar and are firmer.
Don’t overmix the dough once you add the flour.
Overmixing develops gluten in the oat flour, which can make the cookies tough instead of tender. Mixing just until combined ensures a soft, chewy texture.
Let the cookies cool on the baking sheet before moving them.
Cookies are fragile when hot and can crumble if moved too soon. Cooling helps them firm up without becoming hard, preserving their soft interior.
Use parchment paper to prevent sticking and promote even baking.
Parchment paper creates a non-stick surface and helps distribute heat evenly, preventing burnt bottoms and allowing cookies to bake uniformly.
Add a little extra cinnamon on top before baking for a bolder swirl.
Sprinkling cinnamon on top intensifies the flavor and aroma, making the cinnamon swirl more visually appealing and delicious.
Measure flour carefully by spooning into the cup and leveling off.
Scooping flour directly with a cup packs it down, leading to too much flour and dry cookies. Lightly spooning and leveling gives accurate measurement for the right texture.
Store cookies in an airtight container at room temperature for best texture.
Exposure to air dries out cookies quickly. Airtight storage maintains softness and flavor for several days without refrigeration.
Common Mistakes to Avoid
Using underripe bananas
Why it happens Sometimes cooks use bananas that aren’t ripe enough because they want to avoid waste or think green bananas are healthier.
Fix Always use bananas that are heavily speckled or mostly brown for this recipe. They mash easily and bring natural sweetness. If your bananas aren’t ripe, you can speed ripen them by placing them in a paper bag for a day or two.
Overmixing the dough after adding flour
Why it happens Eager to get the dough smooth, many tend to mix too long, thinking it improves texture.
Fix Mix just until the flour disappears. Overmixing activates gluten in oat flour, making cookies tough. Use a gentle folding motion to keep the dough tender.
Skipping preheating the oven
Why it happens Sometimes cooks start assembling dough before the oven is ready to save time.
Fix Preheat the oven fully before baking. This ensures the baking powder activates immediately, giving your cookies proper rise and texture.
Not spacing cookies properly on the baking sheet
Why it happens In a rush, cookies are placed too close together, causing them to merge while baking.
Fix Leave at least 2 inches between cookie mounds to allow spreading. This keeps them individual and ensures even baking.
Removing cookies from the pan too soon
Why it happens Impatience leads to handling hot cookies which are fragile.
Fix Let cookies cool on the baking sheet for at least 5 minutes to firm up. Then transfer gently to avoid crumbling.
Variations
Add chopped walnuts for crunch
Mix in 1/2 cup chopped walnuts to the dough for a nutty crunch that pairs beautifully with the banana and cinnamon. The texture contrast makes the cookies more interesting and satisfying.
Note: Fold nuts in last to avoid overworking the dough. Baking time remains the same.
Chocolate chip twist
Stir in 1/2 cup dark chocolate chips for a richer, indulgent flavor. The bittersweet chocolate complements the natural sweetness of the bananas perfectly.
Note: Add chocolate chips gently at the end; avoid overmixing to keep chips intact.
Gluten-free option using almond flour
Replace sprouted oat flour with almond flour for a gluten-free version. Almond flour adds a moist, tender crumb and a mild nutty flavor.
Note: Almond flour is more moist, so reduce coconut oil slightly to prevent sogginess.
Spiced up with nutmeg and cloves
Add 1/4 teaspoon each of ground nutmeg and cloves along with cinnamon for a warming, spiced cookie that’s perfect for fall or winter.
Note: Mix spices with dry ingredients for even distribution; taste dough to adjust spice level.
Vegan with flax egg substitute
If you want a vegan version, add a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water) mixed and set for 5 minutes instead of regular eggs.
Note: Flax eggs add moisture but may slightly change texture to be more crumbly.

Storage & Tips
Room Temperature
Store the banana oat cookies in an airtight container at room temperature for up to 3 days. Keep them away from direct sunlight or heat sources to prevent drying out. They stay soft and flavorful this way.
Refrigerator
You can refrigerate the cookies in an airtight container for up to 7 days. Note that chilling may cause them to firm up and lose some softness. To enjoy, bring to room temperature or warm briefly in the microwave.
Freezer
Freeze the cookies in a sealed freezer-safe bag or container for up to 3 months. Wrap individually in parchment paper before freezing to prevent sticking. Thaw at room temperature for a few hours, or warm gently in the oven to restore softness.
Reheating
Reheat cookies in a 300°F oven for 5-7 minutes or microwave for 15-20 seconds with a damp paper towel to keep them moist. Avoid overheating which can make them dry and crumbly.
Make Ahead
You can prepare the cookie dough a day ahead and store it covered in the fridge. When ready to bake, allow dough to come to room temperature for about 15 minutes for easier scooping. Bake as usual for fresh cookies.
FAQ
Can I use regular oat flour instead of sprouted oat flour?
Yes, regular oat flour can be used as a substitute. However, sprouted oat flour has a nuttier flavor and slightly different absorption properties, so the texture may vary a bit. You might need to adjust the moisture slightly if the dough feels too dry or wet.
What if my bananas aren’t ripe enough?
If your bananas are underripe, the cookies won’t be as sweet or moist. To ripen bananas quickly, place them in a paper bag at room temperature for 1-2 days. Alternatively, you can microwave bananas for 20-30 seconds to soften them, but this may slightly affect flavor.
Can I make these cookies gluten-free?
Absolutely! Use almond flour or a certified gluten-free oat flour blend instead of sprouted oat flour. Keep in mind almond flour will make cookies more tender and moist, so you may want to slightly reduce coconut oil to balance.
How do I store leftover cookies?
Store leftover cookies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. Reheat gently to restore softness.
Can I add mix-ins like nuts or chocolate chips?
Yes! Adding 1/2 cup chopped nuts or chocolate chips works great. Fold them in gently at the end to avoid overmixing. This adds texture and flavor variety to the cookies.
What causes cookies to be crumbly?
Crumbly cookies often result from overbaking, too much flour, or underripe bananas. Make sure to measure flour properly, use ripe bananas, and bake just until edges are golden but centers remain soft.
Can I use a different oil instead of coconut oil?
You can use mild vegetable or canola oil, but coconut oil adds richness and helps the cookies set properly. Butter is also an option but will change texture and flavor, so reduce quantity slightly.
How do I get a stronger cinnamon swirl effect?
Try sprinkling extra cinnamon on top of the cookie dough mounds before baking. You can also mix cinnamon with a little sugar and swirl it into the dough gently for a more visible effect.
