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.

- 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.

Having made many GF and naturally sweet muffins, I’ll say these are among the best, lots of flavor, extremely fluffy. I used maple syrup and added ⅓ t allspice, and some dried fruit.This recipe is going to the top of my pinterest list!!
Very good. I used almond butter and doubled the oats by mistake. Kids, husband and myself liked them a lot.
Great recipe to use ripe bananas! I topped with mini chocolate chips and oats. They look and taste great!
Thank you for the super receip. Very good for breadfastfast. I have baked sO many times. My sister likes it too..I used pumpkin instead of bananas..
What can i use if i dont have any of those butters?
Best recipe ever! Guilt free. Flavorful and healthy. Like baked oatmeal. I added cranberries and some orange oil and yum!!! I make them a few times a week
These were EXCELLENT! I made some substitutions based on what I had available. I used 2/3c applesauce as recommended instead of banana, maple syrup instead of honey, and I added some cinnamon. They were so quick and easy to make. I actually filled out my whole 12 cup tin and they were still perfect, just a little smaller. I don’t think I’ve ever had a muffin that was so moist before. I’m excited to try the bananas and add some blueberries next time!
Can I use coconut sugar Instead of maple syrup for the vegan version?
I haven’t tested that, so I can’t say for sure, but I’d love to hear if you experiment with it!
Love these! I’ve made two batches over the last week and they barely last two days lol. I’m going to try the version with applesauce instead of bananas next.
For some reason this was a confusing recipe, perhaps it is just the day for me. I made them for my husband as we had the ingredients. My mistake was that I made with a hand mixer instead of blender so the oatmeal did not break down enough to make flour. Now I get this recipe. So it is like a steamed pudding texture, which the husband seems to like so not a complete failure by any means. He said he could not wait until after dinner so he could not wait to have another one after dinner, so that is a good sign. Next time I try it, I will definitely make oat flour out of the oatmeal and give another try in the future. So with this one, you truly do need to use the Vitamix or use oat flour in the recipe. I have to say though I like all of your muffin recipes and the fact that they are healthier than traditional muffins.
