These banana oatmeal muffins are about to become your most-made muffin recipe. That’s because they taste amazing and are super-quick to prepare. Just toss a few ingredients into a blender, and it’s ready to pour into your muffin tin!
What makes this recipe special is that it requires NO flour. I spent weeks testing an oatmeal-based muffin to make sure it turned out tender, not gummy. (If you add too much liquid, it will become gummy, FYI.)
The resulting muffin is gluten-free and naturally sweetened with bananas and a touch of maple syrup. They make the perfect after-school snack or a fast breakfast on the go!

“These muffins turned out great! The texture was better than any other oat-only muffin recipe I’ve made before!” – Lydia

Oatmeal Banana Muffin Ingredients
- Ripe Bananas. You’ll need 2 ripe bananas to make this recipe. The more spots on their skin, the sweeter they will be. I recommend using large ones, so you’ll get maximum banana flavor and more overall muffin batter.
- Rolled Oats. I use old-fashioned oatmeal to make this recipe, but quick oats would likely work, too. Don’t use steel-cut oats, or the texture might not be as nice. If you need this recipe to be gluten-free, shop for certified gluten-free oats on the label.
- Eggs. These are a huge help with gluten-free baking. They help make the muffins rise and become fluffy, so I don’t recommend using an egg substitute here. Try my Vegan & Gluten-Free Banana Muffins if you need an egg-free option.
- Coconut Sugar. I tested this recipe with maple syrup first, the the texture turned out too gummy in the middle. Using granulated sugar helps prevent that! If you don’t keep coconut sugar on hand, regular white or brown sugar will work, too.
- Baking Powder. Not to be confused with baking soda, this helps the muffins rise as high as possible. (Helping to create a fluffy texture.)
- Spices. Cinnamon and salt help to boost the flavor.

How to Make Healthy Banana Oatmeal Muffins
Step 1:
Preheat the oven to 350ºF and line a standard muffin pan with 12 parchment paper muffin cups. This recipe moves quickly, so you want the oven to be heating up for as long as possible.
In a high-speed blender, add 1.5 cups of rolled oats, 2 ripe bananas, 3 large eggs, 1/2 cup of coconut sugar, 2 tablespoons of olive oil, 1 teaspoon of ground cinnamon, 2 teaspoons of baking powder, and 1/4 teaspoon of fine sea salt.
Secure the lid and blend until smooth.
You may need to use your blender’s tamper to help keep things blending at first, or stop and scrape down the sides of the blender with a spatula, if needed. There should be no visible pieces of oats in your batter.

Step 2:
Pour the batter evenly into the 12 muffin cups, then add a few chocolate chips on top, if you’d like. (You can also add a few walnuts, or any other mix-ins you like.) Oatmeal-based batter will thicken if you let it rest in the blender, so I recommend pouring it quickly to make it easier to work with.
Bake at 350ºF until the muffins rise in the center, about 25 minutes.
Note: I usually fill each cup about 3/4 full, but it may vary each time depending on the size of your bananas.

Step 3:
When the muffins feel firm to the touch in the center, remove the pan from the oven and let them cool for at least 15 minutes. Then transfer them to a wire rack to finish cooling completely.
You can serve these muffins at room temperature or store them in an airtight container in the fridge for up to a week.


Banana Oatmeal Muffins (No Flour!)
Ingredients
- 2 ripe bananas
- 3 large eggs
- 2 tablespoons olive oil
- 1 ½ cups old-fashioned rolled oats
- ½ cup coconut sugar
- 1 teaspoon ground cinnamon
- 2 teaspoons baking powder
- ¼ teaspoon salt
Optional Toppings
- ⅓ cup chocolate chips (mini or regular size)
Instructions
- Preheat the oven to 350ºF and line a muffin tin with 12 muffin liners. Into a blender, add the bananas, eggs, olive oil, oats, sugar, cinnamon, baking powder, and salt. Blend until the batter is relatively smooth, about 60 seconds.
- Pour the batter into the 12 muffin cups. They should be about ¾ of the way filled. Add a sprinkle of rolled oats or chocolate chips on top, if you like. You can also add in any other mix-ins you like, such as chopped walnuts or pecans, by pressing them into the muffins.
- Bake the muffins for 25 minutes at 350ºF, or until the centers feel firm to a light touch. Remove the pan from the oven and let the muffins cool completely, then they will be ready to serve.
- Store leftover muffins in an airtight container for up to 1 week. Or you can freeze them for up to 3 months. To thaw frozen muffins, transfer them to the fridge at least 24 hours before you plan on serving them again.

These muffins are so good and so easy to make. I keep making them as soon as they are gone and that is pretty fast
I experimente with each new batch. I substitute honey with agave syrop and I add fresh banana or blueberry 😋
Hi, im in the uk and find lots of conflicting conversions of us cups to grams. What do you use? Love your recipes…. been following you for years and have your book x
1 cup is 250ml. You can do the rest of the math
What or how much of ingredients. In blender. I didn’t see how much of each
Hi Joan! You can see the measurements in the printable recipe card here: https://detoxinista.com/banana-oatmeal-muffins/#wprm-recipe-container-30746
Hi,Your recipe sounds deliciousMy son is allergic to seeds and nuts.what can i use instead of those in this recipe.
These were delicious!! I made them with tahini and chocolate chips. They took a bit longer to cook (maybe it’s my oven or the runnier tahini— the mini muffins took approx 5 mins longer than called). But so tasty and easy! I also made big muffins which took about 35 minutes to bake. Love these!
I made the banana oatmeal muffins but substituted the applesauce instead of the bananas and added organic dark chocolate chips.I added 5 or 6 to each muffin on top along with the rolled oats. They were delicious!
Thanks for letting me know! I’m glad you enjoyed them with the applesauce. Love adding chocolate chips on top, too!
Love these muffins! I added raisins to half the batch, and chocolate chips to the other half. Both are so good!
Loved this! I’m missing flour and these hit the spot. Even my kids enjoyed this and I didn’t even add any chocolate chips this time. I will make these often as it was so easy and made very little mess to clean. Thanks so much for sharing your “clean” recipes. My gut is already starting to feel better and it’s only day two! I look forward to trying more of your recipes.
I love your recipes! Thank you. In this recipe you indicated 1/4 cup of peanut butter in the explanation section above the recipe but in the recipe it calls for 1/2 cup of peanut butter. Would you kindly clarify so I can get baking them! Thanks so much.
Sorry for the confusion! The description above tells you how to make a VEGAN version of this recipe, and in that case you only use 1/4 cup of almond butter. If using the recipe that calls for an egg, you use the 1/2 cup as stated on the recipe card. Hope that helps!
I was wondering if this same recipe would work in a waffle maker to make waffles.
These are so good, and so easy! I could see them becoming a weekly staple for fast school breakfasts.
I just made this recipe! My toddler really wanted to make muffins and we made these so fast, prob 5 whole minutes to put together with an almost 3 yr old as my helper. I didn’t have coconut sugar, I used aquarter cup of brown sugar and it still worked out great! Thanks for such an incredibly easy recipe for this busy mama!
