THANK YOU! This is the first GF baked goods recipe that I’ve had success with. They were light and fluffy inside but did take a full 18 minutes to bake. I used Divided Sunset gluten free all-purpose flour and Bob’s Red Mill quick-cooking rolled whole-grain oats. I also subbed a tablespoon of chopped Craisins for half of a banana.” Lori W., Pinterest comment

How To Ripen Bananas:

If your bananas are not fully ripe, and you want to know how to ripen your bananas, here are a couple of ways to ripen your bananas quickly:

  • Bake them for 20 minutes on low 200º F. This is the fastest way to ripen them.
  • Toss them (skin on) on the grill for a few minutes.
  • If you have time, put them in a paper bag and seal them shut for a day or two.

Flour Blends Tested:

1. King Arthur Measure for Measure—This blend works really well in my recipes. I don’t have to let the flour blend rest in the batter.
2. Bob’s Red Mill 1:1 Blend—This blend also works well, but this flour blend does benefit from resting the batter for 15 minutes before baking. The rest allows the rice flour in this blend to soften, so you don’t have gritty baked goods.

Ingredient Notes:

  • Gluten Free Oats – It is critical to use gluten free oats. There is a lot of controversy over regular oats. If you need to be gluten-free for medical reasons, ensuring your oats are certified gluten-free is important. Although oats don’t naturally contain gluten, cross-contamination is very common.
  • Gluten Free Flour Blend – I tested the blends above, but ensure the blend you use has a binder like xanthan gum, guar gum, or psyllium husk. My DIY Gluten Free Flour Blend is a great flour to use in this recipe.
  • Coconut Sugar – You can use this to use unrefined sugar or brown sugar.
  • Baking Powder – Use aluminum-free if you can.
  • Chia Seeds – These are optional, but add more protein to the muffins.
  • Eggs – Use size large eggs.
  • Oil – Use coconut oil or another light oil.

If you want to know which gluten free flour blend to use for gluten free muffins, I tested four easy-to-find gluten-free flour blends.

Variations and Substitutions:

  • These are delicious gluten free banana bread muffins. You can also make a loaf of banana bread with the batter if you prefer gluten free banana bread.
  • Add nuts like pecans or walnuts.
  • Chocolate chips are fun to add…there is nothing better than banana and chocolate!
  • Substitute the eggs for Bob’s Red Mill Egg Replacer to make this egg-free. One of my readers, Meagan, had good luck using flax eggs in this recipe.

Step-By-Step Photos and Directions:

The oatmeal muffins dry ingredients in a glass mixing bowl.

Step 1: Preheat the oven to 350º F. Add all of the dry ingredients to a large mixing bowl. Whisk to blend these ingredients.

The wet and dry ingredients in a bowl.

Step 2: In a medium-sized bowl, add the banana and use a fork to smash it into a mash. (Note: be sure to melt the coconut oil if it is solid.) Add the rest of the wet ingredients and whisk to blend.

Step 3: Pour the wet ingredients into the dry ingredients and mix gently.

*When mixing muffin batter, the secret to light and fluffy muffins is to “just” mix the batter. It keeps the batter full of air, making your muffins fluffier. Over-mixing deflates any air in the batter, and you can end up with heavy muffins.

I don’t recommend a stand mixer because it can overmix your batter. Overmixed batter will make these gluten free banana oat muffins turn out denser.

Step 4: Add your batter to a lined muffin tin and bake at 350º F. For large muffins, bake for 25-30 minutes. For smaller mini muffins, bake for about 15 minutes.

Frequently Asked Questions:

How do you know when the muffins are done baking?

To test for doneness, insert a toothpick into the center of the muffins. If the toothpick comes out clean, it is done baking. If you see batter or crumbs, the muffins must be baked longer.

Can you use quick oats instead?

You can use quick oats, but it will change the texture of these muffins slightly. Quick oats will absorb less liquid, so you may need to look at your batter to ensure their consistency is similar to my photo below.

How long will these keep fresh?

These muffins will last up to 4 days in an airtight container or up to 4 months in the freezer.

How do you freeze the extra muffins?

These mini muffins are easy to freeze. Just place cooled muffins into a freezer-safe zip-style bag and seal.

“I would actually go as far as saying this is one of the best banana muffin recipes I have ever tried. They were super sweet, moist, and delicious. They definitely didn’t taste like a healthier alternative even though the ingredients used were “better for you” options like coconut oil and coconut sugar. I used 3 ripe bananas and swapped the chia seeds for flax since I was out. This recipe will definitely become a staple in my rotation!”

Diane R

Meagan made these changes: “Also added finely chopped walnuts and mini chocolate chips. Subbed flax egg and regular sugar for the coconut sugar(only used 1/4 of a cup). Muffins took approx 17 minutes to bake fully. It is delicious and has a great texture! Will be making again.”

Erin M made these changes: “These are great! I didn’t have chia seeds, so I used ground flax seeds instead. I don’t always love the flavor of coconut sugar, so I used 1/2 c. coconut sugar and 1/4 c. maple syrup. Perfect!”

  • ½ teaspoon baking soda
  • teaspoon salt
  • 1 tablespoon chia seeds

  • 2 teaspoons pure vanilla extract
  • 2 large eggs
  • cup coconut oil melted
  • ¾ cup coconut sugar or brown sugar

Instructions
 

  • Preheat the oven to 350 degrees F. For best results, ensure the rack is positioned in the middle of the oven.
  • In a large mixing bowl, add dry ingredients and whisk to blend.
  • In a medium bowl, add the bananas and use a fork to mash the bananas into a paste.
  • Add the rest of the wet ingredients to the banana mash and mix well.

Notes

  1. Please make sure you use certified gluten free oats. This is critical if you have Celiac disease or are avoiding gluten for medical reasons.
  2. Any gluten free flour blend should work well in this recipe.
  3. I recommend using rolled oats. Quick oats can work, but the muffin texture will be different.
  4. The chia seeds are optional.
  5. Use Bob’s Red Mill Egg Replacer or a flax egg if you are egg-free.
  6. Store in an airtight container in the fridge for up to 4 days. Freeze in a large zipper-style freezer bag.

SPECIAL NOTE

Please know that every gluten free flour blend has a different starch to grain ratio. If you use a blend I didn’t test, you may need to adjust your moisture levels in your baked goods.

    My. GUY!! This recipe is SO GOOD! I have an egg allergy so I sub’d the eggs for flax eggs (2T ground flax mixed with 5T hot water; let it sit 5 mins then use). I made these large muffins with my 1 yr old daughter a few hours ago and have nearly eaten them all! Big stamp of approval from my non-dessert/sweet/muffin eating husband! Thanks so much!

  2. 5 stars
    Love these and all the helpful tips on brands tested, etc. I have 8 year old grandson with so many food restrictions and you have made things so much easier! I used egg substitute/flaxseed meal and made the large muffins. I added chocolate chips. Shared the text with my sister who uses gluten free and she called me to thank me for the recipe! I’ll be trying more of your recipes! Thank you!

  3. 5 stars
    These muffins were so good! I say “were” because they’re already gone after making them last night. Often times gluten free recipes have the tendency to be dry or crumbly, but not these! I added chocolate chips just because I like the chocolate/banana combo. Next time I will try adding blueberries for a different twist. Thank you for sharing your recipe!

  4. 5 stars
    This muffins were absolutely delicious, easy to make and nice to have a clean treat!!!! Thank you so much for posting your recipe online 😉

    1. I am so glad you liked these Carolina. My kids think you have wonderful taste and now they are asking me to make a double batch :-).

  5. Nice tips on how to make your bananas be ready for the muffins!. I had no idea there were ways to ripen them. Oh and I love how you added walnuts to the recipe. Those muffins look amazing!

  6. 5 stars
    I love how you use coconut oil and coconut sugar in this! So much flavour right there…and there’s chia seeds! What a neat surprise! 🙂 Gives so much texture! Love this

  7. 5 stars
    I love little muffins like these! And banana muffins are one of my faves. I actually have a ton of brown bananas in my freezer. I should get to work 🙂

  8. 5 stars
    I had no idea you could ripen bananas in the oven. I have to try it! Thanks for the recipe. Your muffins looks delicious.

  9. 5 stars
    I didn’t even think about oats getting gluten during cross contamination! That is so good to know and it’s also good to know that you can get gluten free oats! Love these banana muffins!

    1. Hi Nikki, I haven’t tested with flax eggs. If you try it, can you please come back and let us know how it worked?

  10. 5 stars
    Just stumbled across this recipe and looks amazing, I have lots of almond and coconut flour I need to use. Would it be ok to substitute the Gluten Free Flour for Almond flour?

    1. Hi Ray, So a few things. Almond flour by itself won’t work. It doesn’t absorb liquid the same way. You can definitely do a combination of almond and gluten free flour, but just almond flour won’t bake right. Are you trying to avoid gluten free flour? If you look at the paleo pear muffin recipe on my blog, that can give you an idea how to use coconut and almond flours.

    These are the best! I always add three bananas instead of two. GF muffins can often be dry but this makes it super (sorry!) moist! Thanks for the recipe!

    1. I am so glad you liked this recipe Leah. I will make mine with an extra banana next time. Have a great weekend and thank you for making my day 🙂

    1. Hi Lauren, You can definitely omit the chia seeds (maybe substitute them for flaxseed meal?) Also, regular sugar will be fine too. I wish you all the best, Sandi
