Even with nearly 2 cups of mashed banana, these gluten free banana muffins bake up tall and golden, with deep banana flavor and a soft, fluffy crumb that never turns heavy or gummy.

Why this recipe works
A generous 1¾ cups of mashed ripe bananas gives these muffins deep banana flavor, but the batter is carefully balanced so the crumb stays light and tender.
The mashed bananas go in last, after most of the batter is mixed. Folding them in gently keeps them from releasing too much moisture, which can make banana muffins gummy.
A combination of melted butter and oil gives the muffins rich flavor and helps them stay moist. Starting them in a very hot oven creates tall domed tops, then lowering the temperature lets the centers bake through without burning.
Recipe ingredients

Here's a little bit about each ingredient in these muffins and why it's worth sourcing the right ones:
- Gluten free flour blend: Provides most of the structure for these muffins. My favorite blends are Better Batter's original blend (which already contains enough xanthan gum), Nicole's Best (with the gum listed in the recipe), or Bob's Red Mill 1-to-1 gluten free blend with an additional 1/4 teaspoon gum since the blend has some, but not enough for muffins that aren't crumbly.
- Baking powder & baking soda: Help the muffins rise and brown in the oven without overbaking.
- Salt: Enhances flavor and balances sweetness.
- Granulated sugar: Adds sweetness and keeps the muffins tender by locking in moisture.
- Eggs: Help the muffins rise and holds the structure of the rise as they cool.
- Mashed bananas: Ripe bananas add flavor, natural sweetness, moisture, and banana aroma. Underripe bananas have less sugar and less moisture, and don't break down fully in the oven. As banana ripen and the skin browns, it also softens, so if your bananas are hard to separate or peel, they're not ready for baking. As long as they're ripe, even if they're not over-ripe, they're fine for baking.
- Sour cream: Adds moisture to bring the batter together, gentle tang, and helps keep the crumb tender.
- Melted butter and neutral oil: The butter adds richness and buttery flavor from the butter and keeps the muffins from tasting oily; the oil's higher concentration of fat that's liquid at room temperature helps the muffins stay moist for longer at room temperature.
- Vanilla extract: Adds depth of flavor.
How to make gluten free banana muffins (step by step photos)
Here's a visual overview of how to make gluten-free banana muffins in your own kitchen, with an explanation of how each step contributes to the best muffins:
Mix the dry ingredients
In a large mixing bowl, place the gluten free flour blend, xanthan gum (if needed), baking powder, baking soda, salt, and sugar, and whisk to combine well and avoid any clumps of leavening.

Add the wet ingredients
Create a well in the center, then add the melted butter, oil, eggs, sour cream, and vanilla. Start to mix just the wet ingredients together in the center of the bowl before combining with the dry ingredients. This allows us to avoid mixing the wet ingredients together in a separate bowl, simplifying the recipe.


Mix in the wet ingredients
Keep mixing the wet ingredients and slowly incorporate as much of the dry ingredients as you can. The mixture will be too thick to mix fully and completely into a smooth batter.
Fold in the mashed bananas
Add all of the mashed bananas and use a spatula to fold them into the mixture. It will loosen up a lot. We add the mashed bananas last to avoid crushing them too much, which would release too much moisture and could lead to a gummy result.


Portion the batter
For the tallest muffins, use 2 muffins wells and line every other well to give the muffins space to expand without interfering with each other. Scoop enough muffin batter into each liner to fill it all the way to the top.
Bake first at 425°F
Bake this very high temperature for 5 minutes to activate the baking powder quickly and force the muffin batter to rise upward quickly, and the outermost layer of the muffins to set into a dome.
Finish baking at 350°F
Quickly reduce the oven temperature to 350°F and continue to bake for about another 15 minutes or until the tops spring back when pressed gently in the center and muffins are golden brown. This temperature reduction allows you to bake the muffins all the way through without burning them. Let the muffins cool for just 5 minutes in the tin before transferring them to a wire rack to finish cooling.


Expert tips
For the tallest muffins
Start with a hotter oven of 425°F for the first 5 minutes of baking to create more oven spring in the first few minutes of baking. Then, reduce the oven temperature to 350°F to finish baking without burning your muffins. Only baking in every other muffin well can also help get tall muffins.
Remove from the tin quickly
Don't leave baked muffins in the tin for much longer than 5 minutes or the muffins will steam in the liners and the outside can be become unpleasantly chewy.
Ingredient substitutions
If you have additional dietary restrictions, here’s how you can modify this recipe:
Dairy free
Replace the butter with virgin coconut oil (melted and cooled). Triple-filtered coconut oil is best if you don’t want any coconut flavor. For the sour cream, try dairy free sour cream or strain dairy free plain yogurt until it's the consistency of Greek-style yogurt before measuring it for the recipe.
Egg free
You can try replacing the 2 eggs in this recipe with 1 chia egg (1 tablespoon ground chia seeds mixed with 2 tablespoons water, and allowed to gel) per egg, Bob's Red Mill's egg replacer, or “Just Egg” refrigerated egg replacer.

Storage instructions
Let muffins cool completely before storing to avoid sogginess. Keep them in an airtight container at room temperature up to 5 days.
To refresh a slightly dry muffin, run it briefly under cold water and warm it in a toaster oven at 300°F for a couple minutes.
For longer storage, freeze, place cooled muffins on a baking sheet until solid, then store in a zip-top bag for up to 2 months. Thaw at room temp or microwave for 25 seconds. For the best texture, reheat in a low toaster oven.

Gluten Free Banana Muffins Recipe

Ingredients
- 2 ⅔ cups (375 g) all purpose gluten free flour blend, (See Recipe Notes)
- 1 ⅓ teaspoons xanthan gum, omit if your blend already contains it
- 2 teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon kosher salt
- 1 cup (200 g) granulated sugar
- 4 tablespoons (56 g) unsalted butter, melted and cooled
- 4 tablespoons (56 g) neutral oil, canola, vegetable, peanut, or grapeseed oil, etc.
- 2 (100 g out of shell) eggs, at room temperature, beaten
- ½ cup (113 g) sour cream, or plain Greek-style yogurt, at room temperature
- 1 teaspoon pure vanilla extract
- 1 ¾ cups (350 g) mashed ripe bananas, from about 4 medium or 3 large bananas
- Coarse sugar, for sprinkling (optional)
Instructions
- Preheat your oven to 425°F. Use muffin liners to line every well of a standard 12-cup muffin tin or every other well of 2 standard 12-cup muffin tins. For the tallest muffins, line every other well.
- In a large bowl, place the flour, xanthan gum, baking powder, baking soda, salt and sugar, and whisk to combine well.
- Create a well in the center of the dry ingredients, and add the melted butter, oil, eggs, sour cream, and vanilla.
- Mix the wet ingredients in small circles toward the center, then continue mixing to incorporate most of the dry ingredients. The mixture will be too thick to mix until smooth.
- Add the mashed bananas, and mix to combine fully without breaking the bananas too much. The mixture be lumpy because of the bananas, and thick but relatively soft.
- Fill every lined well of your muffin tin(s) completely, all the way to the top of the liner. Sprinkle the tops lightly with the optional coarse sugar, if using.
- Bake in the center of the preheated oven for 5 minutes, then reduce the oven temperature to 350°F.
- Bake at the lower temperature until a toothpick comes out mostly clean (not wet, with no more than a few moist crumbs) and the muffins bounce back when pressed gently in the center, about 15 minutes more. If your muffins still aren't done baking at nearly 15 minutes, reduce the oven temperature to 325°F to continue baking without burning the bottoms.
- Allow them to cool in the tin for 5 minutes before transferring to a wire rack to cool completely.
- Repeat with the remaining muffin tin if you've used 2 tins.

FAQs
Yes! Just be sure they're fully thawed before adding them to the batter. Frozen bananas release water as they defrost, so be sure to use both the fruit and the liquid to maintain the right moisture balance.
This usually means they were underbaked. The muffins may have looked done outside while still raw in the center, often caused by an oven running too hot. Use an oven thermometer and bake until the centers spring back.
Yes! Use a 24-cup mini muffin tin and fill each well to the top. Start checking for doneness at 15 minutes, and bake at 350°F from start to finish. They’re ready when the tops spring back when gently pressed.
Yes. Add up to 1/2 cup chocolate chips, or 2 to 3 ounces of chopped nuts like walnuts or pecans. You can also stir in 1 teaspoon of ground cinnamon with the dry ingredients for a warm, spiced variation.















Made this recipe to share with the neighbor. I used 1/2 c whole milk yogurt and 1/2 c whole milk in place of the buttermilk. This recipe is my favorite go to banana muffin recipe. Always a hit. This made 18 muffin tops baked w/Nicole’s directions for 13 minutes.
Hi! I’ve been looking for a good gluten free banana muffin recipe for quite a while. Do you think I could use Measure 4 measure GF flour blend in place of your gf flour blend? I have it already and hoping it will work with this recipe.
Thank you so much!
That is not a properly balanced flour blend, Annie, and tends to be of inconsistent quality. The rice flour is gritty as well.
I would greatly appreciate it if you include recipes that are gluten free and dairy free baked goods. It is difficult to find delicious gluten free recipes that are also dairy free. I am confident if anyone is able to come up with such recipes it is you! Thank You.
I don’t specialize in dairy free recipes, although there are other bloggers who. All I can really offer is suggestions on how to make any given recipe dairy free as well, which you can find in the “ingredients and substitutions” section of each recipe post.
Making the all purpose GF flour seems so complicated with specialty ingredients that are not easily found in stores and even online it gets expensive. I get discouraged every time I consider making or buying GF flours. I’ve been sticking to a basic blend of rice flour, tapioca starch and xanthan gum, although it is not a perfect texture but is simpler for my busy life.
I understand, Cary, and there are plenty of blogs out there with recipes that are less exact and produce “okay” results. This is not that blog, though. It sounds like you know what works for you, and you should go find it!
Just to let you know. I take one packet(1 t.) powdered stevia, mix with 1 cup sugar. You now have a sweetener which has twice. The sweetness. So the recipe calls for 1 cup sugar, use 1/2 c, I have used it successfully in your banana muffins and your morning glory muffins. .
Hope this helps others
Made these today. Totally yummy! I didn’t realize the recipe was for 16 muffins so I filled the muffin wells with all of the batter, fairly evenly distributed. Muffins took a bit longer to bake but they are fluffy and tasty. I also added about 2/3 c. Walnut pieces for texture and flavour.
Those must be some really big, beautiful gf banana walnut muffins, Karen!
Is it possible to substitute the sugar with an alternative like Monk Fruit, or erythritol/Monk fruit blend?
You can always try using an alternative sugar (I like Lankato brand monkfruit granulated sugar alternative best), but it is very drying, so you may have to add more liquid and I can’t promise results. If you add too much, though, the muffins will be dense and gooey. Watch the video and photos carefully and try to mimic the texture you see. Good luck!
I accidentally made it without eggs and they turned out fabulous! I also happened to use Bob’s Red Mill all-purpose b/c I was out of rice flour. Happy accident!
Funny about the bananas! I always just freeze them with the peels on in a freezer bag! I think it might be better Nicole’s way as they are a sticky mess to peel!
Oh my gosh definitely peel and chop them first, Cherie! That way you can use what you like, rather than having to defrost and use an entire banana—and struggling with the peel. ☺️
Thanks for the tip, Nicole, regarding greasefree liners, I had never heard of them. Just an update, after making these this morning, I keep going back and having another :-) and another :-) well, you get the idea. They are amazing, and great all day, not just for breakfast! I absolutely love all your recipes, thank you so much for your attention to detail and delicious creativity.
That’s great, Pam! Thanks for letting us know. And yes, greaseproof liners are essential. I’m not really sure how I ever used the ones from the grocery store shelves. They always stick!
