These moist and chewy banana oatmeal cookies are hands down the best banana flavored cookie I’ve ever had. Not only are they moist and chewy for days, they are unmistakably banana-y!
Banana is one of those flavors that can get lost when you bake with it. It can be a really subtle flavor. It always bums me out when that happens, because we love the taste of banana.
These cookies meet the category of being FULL of banana flavor. Just the smell of this cookie dough mixture with the banana in it is intoxicating. And they are so moist and tender, the nearly melt in your mouth. They are perfect for using up overripe bananas and super easy to make. You don’t even need a mixer!
This is one of those old fashioned recipes that everyone loves. It’s originally from my grandmother’s cookbook. Her book is full of newspaper clippings with recipes and the names of those who submitted and shared them with the paper. I just love it. Such a different time in the world. Now we find everything online!
These cookies make the list of banana things to go crazy for. Without a doubt, it’s a tie between them and my Banana Bread Recipe! Or, maybe they are tied with my Banana Cupcakes or Banana Chocolate Chip Layer Cake. Then there’s my Homemade Banana Pudding — I just can’t decide. Banana desserts are just so tempting.
- Texture. These cookies are super soft and tender and they stay that way for several days.
- Nutritious. With both banana and oats in these cookies, they are packed with nutrients. I love them on busy mornings when I need breakfast on the go!
- Easy to make. Making these tasty banana cookies is just as easy as eating them. They’d be great to make with kids! You can mix everything in one bowl. That means less clean up, and that’s always a good thing.
- Grandma’s recipe. Another reason this recipe is extra special is because I got if from my grandmother (my dad’s mom). She passed away in 2008. A few years after she passed, when I started baking a lot, my uncle gave me her cookbook. This recipe was tucked inside it, and it brings back so many special memories. I made a few changes to her original recipe to make the cookies thicker and softer, but they are essentially the same as grandma used to make.
What You’ll Need
- All-purpose flour: Be sure to measure your flour. Too much flour and you’ll end up with dry cookies, too little and they’ll get runny.
- Baking soda: A little baking soda gives the cookies a light, fluffy texture.
- Ground cinnamon & cloves: These warm spices nicely compliment the banana.
- Salt: Helps to enhance the flavors and spices in the cookie dough batter.
- Cornstarch: This is one of the secret ingredients for this recipe. Cornstarch gives the cookies a chewy texture, helps them not over spread and gives them a lovely soft texture.
- Unsalted butter: I highly recommend using unsalted butter because it allows you to control the saltiness of the cookies. However, salted butter will also work, but you’ll want to leave out the rest of the salt in the recipe.
- Sugar: Using both granulated sugar and brown sugar gives the cookies a deep, richer flavor. The brown sugar also provides extra moisture.
- Egg: You’ll need 1 egg to bind all your ingredients together.
- Vanilla extract: You can’t go wrong adding a little vanilla to banana cookies.
- Bananas: Make sure to use overripe bananas for the best flavor. They should have plenty of brown spots, but not be completely brown and nearly falling apart. If they don’t hold together anymore, they are probably too ripe and your cookies may not turn out well.
- Oats: This recipe originally called for old-fashioned rolled oats but after some kitchen testing, I decided I like quick 1-minute oats better. The texture of the cookies is a little softer when you use quick oats, but either will work.
Here’s a quick look at how to make this banana cookie recipe. Don’t forget to scroll to the recipe card below for more detailed instructions.
- Prepare the dry ingredients. Add the flour, baking soda, cinnamon, cloves, salt and cornstarch to a medium sized bowl and whisk together. Set aside.
- Combine the butter and sugars. Add the melted butter and sugars to a large bowl and whisk to combine.
- Add the egg and vanilla. Whisk the egg and vanilla extract into the creamed mixture until well combined.
- Add the mashed bananas: Add the mashed bananas to the creamed mixture and whisk together until well combined.
- Add dry ingredients. Stir the dry ingredients into the batter and mix until just combined.
- Add the oats. Pour in the oats and fold together until well combined.
- Form the dough balls. Create cookie dough balls that are 1 ½ tablespoons in size.
- Refrigerate (optional). If desired, chill the dough balls in the refrigerator for 2-3 hours or overnight. The longer they are refrigerated, the stronger the banana flavor will be.
- Prepare to bake. When you’re ready to bake the cookies, preheat the oven to 350 degrees Fahrenheit, line a cookie sheet with a silicone baking mat or parchment paper and arrange the cookie dough balls on the baking sheet. (No need to bring the cookies to room temperature. You can bake them immediately after pulling them from the fridge.)
- Bake. Place in the oven and bake for about 10 minutes.
- Cool. Allow cookies to cool on the baking sheet for about 5 minutes before moving them to a cooling rack lined with parchment paper.
Tips for Success
These simple suggestions will help guide you through the process of making these cookies. Check them out to make the best banana cookies.
- Measure carefully. Proper measuring of the flour and sugar plays a big roll in determining how much your cookies will spread during the baking process. So, measure carefully. If you want to achieve the perfect light, chewy texture, check out my tutorial on How to Measure Flour Correctly. It’s best to use a food scale, but if you don’t have one, use the spoon and level method. Whatever you do, don’t pack the flour into the measuring cup.
- Use quick oats. The biggest change I made when I updated this recipe was switching from old-fashioned oats to quick 1-minute oats. You can totally use either, but I really like the way 1-minute oats absorb more moisture. The cookies not only spread a little less, but they also develop a softer texture, which I love. If you decide to use old-fashioned oats just remember that they won’t absorb as much moisture (and may spread more), and the cookies will turn out a little firmer with a bit more texture.
- Make this recipe with overripe bananas. Make sure to use overripe bananas for the best flavor and texture. They should be soft on the outside and easy to mash when you peel them. They should also smell appetizing. Overripe bananas will have plenty of brown spots, but not be completely brown or nearly falling apart. If they don’t hold together anymore, they are probably too ripe and your cookies won’t bake properly.
- Refrigerate the cookie dough balls. You don’t have to refrigerate them (they will still taste amazing), but I highly recommend refrigerating them at least 2-3 hours; overnight is even better. Refrigeration helps the dry ingredients soak up more moisture, which helps them spread less. It also allows the flavors to permeate the cookie dough better. Cookies refrigerated overnight will have the strongest banana flavor.
- Use parchment paper. These cookies can be a little sticky from all the moisture and sweetness in the bananas. You’ll want to line your cooling racks with parchment paper. If they stick to the parchment paper after cooling (and they probably will), just give them a little twist before lifting them. They will come right off.
Store the cookies in an air-tight container at room temperature. If you are going to stack them in a container, put parchment between the layers so the cookies don’t stick to each other. These cookies are best if eaten within 4-5 days.

Description
These Moist and Chewy Banana Oatmeal Cookies are hands down the best banana flavored cookie I’ve ever had. Not only are they moist and chewy for days, they are unmistakably banana-y!
Ingredients
- 1 1/2 cups (195g) all-purpose flour (measured accurately)
- 1 tsp baking soda
- 1 1/2 tsp ground cinnamon
- 1/4 tsp ground cloves
- 1/2 tsp salt
- 2 tsp cornstarch
- 3/4 cup (168g) unsalted butter, melted
- 1 cup (225g) packed brown sugar
- 1/2 cup (104g) sugar
- 1 large egg
- 1 tsp vanilla extract
- 1 cup (240ml) mashed over ripe bananas (2-3 bananas)
- 3 cups (240g) quick 1-minute oats
Instructions
- Add the flour, baking soda, cinnamon, cloves, salt and cornstarch to a medium sized bowl and whisk together. Set aside.
- Add the melted butter and sugars to a large bowl and whisk to combine.
- Add the egg and vanilla extract and whisk together until well combined. Add the mashed bananas and whisk together until well combined.
- Add the dry ingredients and fold together just until well combined. Add the oats and fold together until well combined.
- Create cookie dough balls that are 1 ½ tablespoons in size. You can refrigerate the cookie dough before baking, if you’d like, but you don’t have to. I think the flavors get even better if you refrigerate the cookie dough for at least 2-3 hours, or overnight.
- When you’re ready to bake the cookies, preheat the oven to 350 degrees F. Line a cookie sheet with a silicon baking mat or parchment paper. (No need to bring the cookies to room temperature. You can bake them immediately after pulling them from the fridge.)
- Bake the cookies for about 10 minutes or until golden around the edges and lightly golden on top.
- Allow the cookies to cool for about 5 minutes, then move to a cooling rack lined with parchment paper to cool completely. The cookies can stick to the parchment paper a little bit. I find that it helps them to release if you give them a little twist on the paper before lifting them up.
- Store cookies in an air-tight container with parchment paper between the stacks of cookies so they don’t stick to each other. Cookies are best if eaten within 4-5 days.

I LOVED THEM, but I’ve yet to meet an oatmeal cookie I didn’t like. Husband didn’t care for them much but I’ve yet to find a use for ripe banana that he does like even though he loves bananas. Definitely a go to recipe for old bananas since neither of us like banana bread. I refrigerated the dough because it was so moist but it was still very sticky 2 hours later, so I don’t think the refrigeration was beneficial.
My cookies didn’t turn out like yours. they were too puffy and outside was cookie, inside was cakey. not what I was looks for when I gave this a try..
Recipe looks great and I’m going to try this tonight. One piece of feedback, next time can you post some photos of the prep, cookies on the tray etc? The finished product looks good but all the photos are the same and no visuals of the steps. Mostly I want to see how flat you make the cookies so they will still spread out like your photos. Thank you!
Thanks for the feedback, Cameron! I hope you enjoy them!
These cookies were a huge hit in my house. I didn’t put the same amount of sugar but that’s only because we are being careful with out sugar intake. But thank you sooo much for sharing from my family to yours.
????❤????
Glad they were a hit!
OMG! Delicious as is (I may or may not have just eaten 9 of them in one sitting)! Added walnuts to 1/2 of them and that was yummy too!
Anyone tried it with oat flour? If so how much did you use?
So glad you enjoyed them!
No! No, no, NO!!!
You can NOT tease me by showing ANY form of a black walnut recipe and cut the picture off so I can’t get the full recipe!!!
That’s just mean! ????????????
Ha! You’re in luck. These are those bars, just slightly modified. I actually left the walnuts out, but you could definitely add them back in.
I used GF flour for this. So good I couldn’t stop eating the batter!! Thank you, thank you!!!!
I’m so glad you enjoyed them!
Just made these and they are fabulous! I love bananas and always have a couple that are too ripe for my taste so this was a great way to use them as we are a cookie kind of family. Thank you!
So glad you enjoyed them!
these sound so good.. i think i am going to make me some later on tonight and add raisins in them too . thanks for the recipe. these would be a “uick out the door when i dont have time to make breakfast “cookies
I hope you enjoyed them!
I made these cookies and they were a hit! The batter was very sweet, so I added a couple handfuls of dried cranberries. Worked very well for something that doesn’t have chocolate!
Just made these cookies. What caught my interest was your comment about how the banana flavor really comes through! You are right. They are soft and moist and delish. Thank you for the recipe!
Hi i know this was posted awhile ago but im sure you still get messages from your blog. That being said, the best way to get the flavor out of bananas is well, should i give my top secret away??? Sure, i learned it from some older lady a few years back and i will never bake anything with bananas in it without doing it first. Make sure your bananas are overripe. Then preheat oven to 350 and line a pan with aluminum foil and bake bananas for around 35-45 minutes. Let cool, un peel and use juice in pan and bake whatever your heart desires. If your bananas are yellow bake at least 1 hr to 115 minutes. At 325. That should help alot with keeping the flavor and add a little orange or lemon zest..
I was on a hunt for recipes using bananas, and am so glad I came across yours! And for more than just the cookies… I live in WV, and my grandmother had the same kind of cookbook – recipes submitted with neat stories to go along with them – that she got from her square dancing club! My great-grandmother (her MIL) was from Belgium, and used to make gaufrettes when I was a little girl. I’ve never been able to find her recipe, and who knows what happened to her iron. Thought the similarities were neat 🙂 Can’t wait to try these cookies!!
Those are some serious coincidences! How funny! And so glad you enjoyed the cookies!
What kind of flour?
All purpose
Hi! I was in search of a good cookie recipe using oats and banana, and found yours. It looked perfect, and had the added advantage of an ingredients list I pretty much already had on hand. I did end up tweaking it – added flax and chia seeds, unsweetened applesauce, a couple other minor tweaks to account missing ingredients – and was worried I overdid it, but the recipe adapted really well! The cookies turned out just the right level of sweet, with great flavor and texture! Loved them, ate half the batch almost right away and set the rest aside for morning snacks with coffee. Thank you for sharing!
I cooked these longer than indicated – if you take them out when edges are golden brown, I found them to be underdone in the centers. I left them in closer to 15 mins until the entire surface was golden brown, which produced a cookie that was cooked through but still very moist and soft.
I made the banana oatmeal cookies and they are exquisite!! Thanks to you and to your grandmother for a wonderful and favorful family recipe.
