These Healthy Banana Oat Muffins are so easy to fall in love with. Every bite is incredibly moist and sweet, you’d never know that they’re gluten free, vegan, egg free, and refined sugar free!

I can’t think of a better way to start the day than enjoying warming bites of cinnamon, banana, and maple. Just like my Paleo Banana Muffins and Strawberry Banana Muffins, these healthy paleo banana oatmeal muffins are made with basic ingredients and make for a simple, nutritious, and delicious snack or breakfast. Throw one in your bag and head out the door!

While these banana oatmeal muffins aren’t quite as quick as my blender muffin recipes, taking the time to gently fold the batter together always pays off in the end. You’ll love how these gluten free banana oat muffins are rich and fluffy, yet still so light-tasting! Plus, the oats and chia seeds inside will keep you full for hours. What could be better?

Why You’ll Love These Gluten-Free Banana Oatmeal Muffins

Allergen – free: These muffins are gluten free, dairy free, egg free and refined sugar free so they are suitable for those with specific allergies or intolerances to these foods.

Yummy: Ripe bananas make these muffins nice and sweet and super moist and oh so flavorful.

Adaptable: You can easily throw in some dark chocolate chips, cocoa nibs, chopped or blueberries. You can also make a batch of 24 mini muffins or bake the batter up in a loaf pan.

Ingredients to make healthy banana oat muffins; coconut flour, oats, salt, milk, honey, almond flour, cinnamon, bananas, olive oil, baking powder, almond flour, vanilla extract, chia seeds.

Banana oat muffin ingredients

  • Almond flour – This is one of my favorite gluten free flours because it’s nutty, versatile, and always produces fluffy results in baking (check out my Honey Almond Flax Bread for proof!).
  • Coconut flour – Mixing almond flour with coconut flour helps ensure the muffins turn out fluffy and rich. The recipe won’t work if you only use one gluten free flour.
  • Rolled oats – Use gluten free old fashioned rolled oats to keep the recipe gluten free.
  • Bananas – Ripe mashed bananas will give the muffins a subtle banana flavor and lots of moisture, just like classic banana bread.
  • Dairy free milk – I tested this recipe with oat and coconut milk but any kind of plant milk will work.
  • Honey or maple syrup – These give the muffins a nice, natural sweetness. Make sure to use maple syrup to make vegan banana oat muffins.
  • Chia seeds or nuts – As a fun and filling add-in!

How to make gluten free banana oatmeal muffins

To start, add all of the dry ingredients (except the chia seeds/nuts) to a large bowl. In a second bowl, mash the bananas with a fork. Whisk in the milk, honey or maple syrup, and vanilla.

Pour the wet mixture into the bowl with the dry ingredients and fold everything together using a spatula. At this point, you can fold in the chia seeds or nuts. Be careful not to overmix!

Scoop some batter into a lined muffin tin until each individual cup is filled almost all the way to the top. Bake until a toothpick inserted in the middle of the muffins comes out clean. Let them cool on a wire rack, then enjoy!

Tips and substitutions for banana muffins with almond flour and oats

  • Mix fun add-ins into the muffin batter! Instead of chia seeds and nuts, fold in chocolate chips, dried fruit, seeds, dark chocolate chunks, and more.
  • Feel free to top the muffins with a sprinkle of oats, chocolate chips, sliced almonds, fresh fruit, or chia seeds right before they go in the oven.
  • For more warmth and comfort in each bite, add a small pinch of nutmeg, cloves, ginger, or allspice to the batter.
  • If you don’t need these to be gluten free, swap the almond and coconut flour with an equal amount of whole wheat flour.
  • The number of bananas matters. Using 4 bananas will help balance the flavors and sweetness in this recipe, and help combat the dryness of the gluten free flours.
  • Use ripe bananas. Make sure there is no green left on the banana peels, they need to be ripe to add a nice sweet flavor to the muffins.


What are the health benefits of banana oat muffins?

Healthy Banana Oat Muffins

by Silvia Dunnirvine
Every bite of these Healthy Banana Oat Muffins is incredibly moist and sweet. You’d never know that they’re gluten free, vegan, egg free, and refined sugar free! Enjoy them as a quick and easy, and family-friendly breakfast or snack.
Prep: 12 minutes
Cook: 25 minutes
Total: 37 minutes
Servings: 12 muffins


  • 1/2 cup coconut flour
  • 1/2 cup almond flour
  • 1 cup rolled oats
  • 2 tsp baking powder
  • 1 tsp ground cinnamon
  • 1 pinch kosher salt
  • 3 ripe bananas
  • 1 cup plant based milk*
  • 1/3 cup honey or maple syrup
  • 1 tsp vanilla extract
  • 1 tbsp chia seeds (or nuts) (optional)


  • Add all the dry ingredients to a large bowl, except the chia seeds or nuts (if using). That will be added in the end.
  • In a second bowl add in the bananas and mash them using a fork, until creamy and very few chunks left (though some banana chunks will give the muffin a good texture).
  • Whisk in the milk, honey or maple syrup and vanilla extract.
  • Pour liquid ingredients into dry bowl and fold, using a spatula until well combined. DO NOT over work the dough. If using chia seeds or nuts, add that in as you start to fold the liquid and dry ingredients.
  • Use an ice cream scooper to easily pour batter into individual muffin cups that are lined with paper muffin liners or silicone molds. Fill more than 3/4 full (almost all the way to the top).
  • Bake at 375F degrees for 23-25 minutes. Insert toothpick to see if the muffins are cooked internally (see notes)**


*recipe was tested with both oat and coconut milk
**oven temperatures vary. Start checking at around 22 minutes. Note that “some” moisture may come out on the toothpick, that’s likely from the very moist bananas. The muffins will naturally “dry out” slightly as they cool down.

  1. This sounds great. I’m wondering –can you just bake in a 9×13 — do you have temp and time for that?

    1. Hi Lorrane, I haven’t tested this in a baking pan but I’d say the temperature should still be the same but cooking times will be longer. If I had to guess I’d say it’s going to take at least 32-35 minutes to bake. Set the time for 35 and keep an eye on it after that, use a toothpick to test the center. Hope this helps
