Oat flour banana muffins are a hearty, delicious healthy banana muffin made with just a few simple ingredients! No refined flour, sugar, butter, or dairy!
So, I did a thing.
I turned my Oat Flour Banana Bread into muffins, and they are freaking DELICIOUS! Super portable, filling, and freezer friendly! Not to mention, they only take 15-20 minutes to bake versus the bread that takes almost an hour. I’ve also made plenty of delicious tasting and super popular oat flour muffins before like my healthy oat flour blueberry muffins, honey oat flour muffins, chocolate chip oat flour muffins, and my pumpkin oat flour muffins.
So, yummy! You guys have been tagging me (@hungryhobbyRD on Instagram) left and right making all kinds of oat flour recipes, especially my banana bread and honey oat bread, I'm so happy y'all are enjoying baking with oat flour at a time when flour and yeast are scarce.

To be honest, oat flour is one of my favorite flours to bake with. It's a little tricky because it's so absorbent, but when you get it right (which usually takes me a couple of tries), the product is so hearty, slightly nutty, and filling.

I enjoyed my muffins slathered with butter for a pre-workout breakfast all week last week, and it was PERFECT! Baby K loved his with peanut butter. It made sense to me because PB & Bananas is one of the best combinations in the world! Let me know how you enjoy yours!
How to Make Oat Flour Banana Muffins
To make these delicious oat flour banana muffins, you'll start by mashing down three medium-large bananas. I like to mash mine in the peel first, then remove the skin and mash further with a fork.
Also, I like to leave my bananas a little chunky, but if you don't want any banana chunks, you may want to use an electric mixer or blender to get rid of the lumps. 
Now, you'll add the rest of your wet ingredients.
And then mix up your dry ingredients. If you make your oat flour right then, go ahead and add to the blender or food processor and give it a spin. If you use oat flour that you've made and stored, you may want to sift it or just whisk well to get rid of clumps.
I've noticed if oat flour sits a while, it can get clumpy, which will then translate to clumps of oat flour in your muffins, NO BUENO! So mix well and try to remove clumps before adding dry to wet ingredients.
Now, the only part I changed about this recipe from bread to muffins was putting it into muffin tins. Make sure to spray or line your muffin tins! I usually use liners, but I didn't have any, luckily these popped out nicely with almost no sticking. I used avocado oil to spray the muffin holes.
TIP: Want perfect muffin tops? Use a large ½ cup ice cream scoop to put the batter into muffin tin holes.
With these muffins, the baking time is quick, only about 15-18 minutes compared to the bread version. Also, make sure that half-way (at the 7-9 minute mark, turn the pan around for even baking.) Insert a toothpick into the center of one of the center muffins in the tray. If it comes out clean, they are done!

Oat Flour Banana Muffins
Ingredients
- 3 cups rolled oats (2.75 cups oat flour)
- 3 large bananas
- .25 cup Unsweetened Vanilla Almond Milk
- ⅓ cup maple syrup
- 2 eggs
- 2 teaspoon cinnamon
- ⅛ teaspoon salt
- ¾ teaspoon baking soda
- 1 teaspoon baking powder
Instructions
- Preheat oven to 350F.
- Using a food processor grind 3 cups of old fashioned rolled oats into fine oat flour. You want 2.75 cups of oat flour so if you end up short, grind more oats into flour. You want to grind so that your oat flour is very fine. (or you can purchase fine oat flour.)
- In a large bowl, mash bananas with a fork. Then, whisk together maple syrup, eggs, mashed bananas, and unsweetened vanilla almond milk.
- Add cinnamon, salt, baking soda, and baking powder to oat flour. Mix to combine evenly.
- Next, add the wet mixture to the flour mixture and mix until totally combined. The batter will be a little sticky, that's okay.
- Let the mixture sit for five minutes.
- Spray with cooking spray or line a muffin tin and fill each muffin hole ⅔ way full.
- Bake for 15-18 minutes until an inserted toothpick comes out clean.
- Let cool COMPLETELY. Ideally, let cool for a few hours on the counter, then let cool completely in the fridge overnight.

After you make these, don't forget to give my honey oat flour muffins a try too! They are delicious on their own or drizzled with butter and honey!
Katherine De Leon says
Thanks for the amazing and wonderful recipe. I did it the way it should be. Perfectly done just like you and healthy recipe too for healthy life.
Sam says
Went looking for a recipe to use some brown bananas and to start making a dent into the copious amount of rolled oats we have, and this is IT! These are chewy in a good way and have a balanced banana and oat flavor. The only changes I made were subbing honey for the maple syrup (didn’t have any) and adding a 1/2 tsp of nutmeg as well (sounded yummy, was yummy 🙂 ). They’re toddler-approved as well! We’ll defs be making these again!
Cory says
Delicious. Added dried blueberries and about a cup of walnuts& pecans. Didn't change temp or bake time. So good.
Kelli Shallal MPH RD says
Love those additions! Thanks for sharing!
CJ says
I tried these and they came out "gummy". Was there supposed to be some oil in them? I notice that your corresponding bread recipe DOES have oil. (I wish I'd noticed that sooner.)
Kelli Shallal MPH RD says
I'm not sure which recipe you are thinking is corresponding, my oat flour banana bread recipe also does not have oil. Sometimes the gummy texture is from too many bananas. But also, the texture of oat flour bread products is different from what most people are used to, I wouldn't say it's gummy but definitely denser. In any case, sorry you didn't love them as much as we do!
Ashley Whiting says
I didn't combine the wet ingredients separately and I did half honey, half maple syrup. I also used regular almond milk and added a dash of vanilla instead. Turned out delicious! Easy to follow recipe with great results. Muffins are soft, moist, and perfectly sweet. They definitely have a relatively chewy oat flour texture, but I like it. Will use again!
Kelli Shallal MPH RD says
Thank you for sharing and so glad you liked them! We love them too 🙂
Jenn says
Amazing!!! I used 1 egg and 1 egg white (because I was missing eggs) as well as added 2-3 chocolate chips per muffin and that little added sweetness is just perfect. Thanks for the recipe
Emerson says
Hi, was gonna make these but realized I don’t have honey or maple syrup, I also don’t really like either of them 😅 would it ruin the muffins texture to skip this ingredient?
Kelli Shallal MPH RD says
Most likely yes. Muffins rely on a balance between wet and dry ingredients. So they may not come out if you substitute or skip it.
Sylwia says
I skipped the honey/maple syrup and added 3 dates instead and doubled the amount of milk and they turned out great ! 🙂
Kelli Shallal MPH RD says
That sounds delicious! Thanks for sharing!
Kel says
A little bland for me. I like my muffin sweet.
Kelli Shallal MPH RD says
These are on the healthier side so not as much sugar as your regular mufin!
Hart says
These were great! I added 1/3 a cup of chia seeds. Delicious and most importantly my 10 month old loved them. Thank you!
Bridget says
Yum! I skipped the maple syrup and added a little more almond milk. I also added vanilla extract and extra cinnamon, and left one cup of the oats as-is, instead of grinding it all into flour. My husband and I both enjoyed them and I will probably make them again as a healthy carb to add to breakfast!
Kelli Shallal MPH RD says
Yum!!!! I love to do that too, bake the oats right in, but some people really hate the texture so I didn't do that in this recipe! But I do it at home!
Emma says
Thank you for this recipe! I found it when I was searching for a treat that all my students with their various food restrictions could eat. I was surprised at how tasty they are! Love the texture and how they feel substantial. I now make these every week with my toddler and feel good that she’s getting some solid nutrition in a muffin. I always add something different- some bran and sesame seeds to replace some of the oat flour, some cardamom, and best of all, frozen blueberries. It’s a really great base recipe.
Kelli Shallal MPH RD says
I make these for my toddler too! So versatile, especially since I can't get them to eat oatmeal anymore!
Judy says
Yes, it is a great base recipe. Ingredients can easily be swapped, subbed etc. and you still end up with a great muffin! I told Kelli this in my initial review of the recipe………..
Judy says
Hi Kelli, the oat flour banana muffins are great! I ended up adding shredded coconut and chopped walnuts to the mix, and because I didn’t have almond milk, I subbed for a like amount of nonfat Greek yogurt. It all worked out and just shows the flexibility of your recipe. They were astonishingly delicious! Yeah you! A tip—-I baked the muffins in a silicone muffin pan—-for me this is so much easier than a metal muffin tin, or using paper liners. Just be sure to give a little PAM spritz to the silicone molds—the muffins will pop out beautifully.
Kelli Shallal MPH RD says
I have some silicone molds I use sometimes too! So glad you enjoyed this!
Cathy D says
Added mini chocolate chips and chopped walnuts. They were delicious! Thank you!
Kelli Shallal MPH RD says
YUM!!!! Love that!
Rose says
Would these still be tasty if I added some molasses to this recipe?
Kelli Shallal MPH RD says
I think it would work!
Rose says
How can molasses be added to this recipe?
Kelli Shallal MPH RD says
Maybe sub a little molasses for the maple syrup!
Rose says
Good idea! I’ve been wanting to make something healthy with a gingerbread flavor.
