what's in it
Key ingredients for bakery-style gf blueberry muffins
- Buttermilk – Adds flavor and creates a soft, tender crumb. No buttermilk? Use half plain yogurt, half milk by volume as a quick substitute.
- Melted butter – Infuses the muffins with rich flavor and moisture.
- Fresh lemon juice – Brightens and enhances the blueberry flavor.
- Eggs – Provide structure and lift.
- Gluten free flour blend + cornstarch – A blend with superfine rice flour and added cornstarch helps mimic bakery-style texture. (See Notes in the recipe card for flour blend tips.)
- Baking powder + baking soda – Ensure a high rise and golden edges.
- Granulated sugar – Adds sweetness and tenderness to the crumb.
- Blueberries – Use fresh or frozen (unthawed) for juicy pockets of flavor in every bite.

Ingredient substitutions
Dairy free
- Use half plain dairy-free yogurt and half unsweetened nondairy milk (like almond or soy) in place of buttermilk.
- Swap the butter for a block-style vegan butter like Miyoko’s or Melt. Avoid tub-style spreads—they’re too soft and oily.
Egg free
- Replace each egg with a chia egg, Bob’s Red Mill Egg Replacer, or JustEgg. Expect slightly less lift, but still a good crumb.
Corn free
- Use arrowroot starch or potato starch in place of cornstarch—either one works well for tender muffins.
Blueberry alternatives
- You can sub in raspberries (fresh or frozen), but if you’re craving strawberries, try my gluten free strawberry muffins instead—they’re formulated specifically for that fruit.
Pro tips for perfect muffins
Start hot for a high dome
Begin baking at 400°F for the first 10 minutes, then lower to 350°F to finish. The high heat activates the baking powder quickly, giving you that classic domed top.
Don’t thaw frozen blueberries
Use them straight from the freezer to prevent bleeding or wilting. Thawed berries break down and turn your batter purple.
Coat berries in flour
Tossing fresh or frozen berries in a tablespoon of the dry ingredients helps suspend them in the batter so they don’t sink.
Smooth tops for an even rise
After portioning the batter into the muffin wells, smooth the tops gently with wet fingers. This helps encourage a more even rise and prevents lopsided muffins.
How to make these muffins
Step 1: Prep the oven and pan
Preheat your oven to 400°F. Grease or line a 12-cup muffin tin and set aside.
Step 2: Mix the wet ingredients
In a medium bowl, whisk together the melted and cooled butter, buttermilk, lemon juice, and eggs until smooth.
Step 3: Whisk the dry ingredients
In a large mixing bowl, combine the gluten free flour blend with xanthan gum, cornstarch, baking powder, baking soda, salt, and sugar.
Step 4: Toss the blueberries
Use 1 tablespoon of the dry mixture to coat your fresh or frozen blueberries so they don't sink to the bottom.
Step 5: Combine wet and dry
Pour the wet mixture into the dry ingredients. Stir until just combined—the batter will be thick.
Step 6: Fold in the berries
Gently fold in the coated blueberries just until evenly distributed.
Step 7: Fill the muffin tin
Divide the batter evenly among the muffin cups, filling them nearly full. Smooth the tops with wet fingers for an even rise.
Step 8: Add the topping
Brush with melted butter and sprinkle with coarse sugar, if using.
Step 9: Bake
Bake at 400°F for 10 minutes, then reduce the temperature to 350°F and bake for another 10–12 minutes, or until a toothpick comes out with a few moist crumbs.
Step 10: Cool
Let the muffins cool in the tin for 10 minutes, then transfer to a wire rack to finish cooling.

Instructions
Make the muffin batter
- Preheat your oven to 400°F. Grease or line a 12-cup muffin tin and set aside.
- In a medium bowl, whisk together the buttermilk, melted butter, lemon juice, and eggs until well combined.
- In a large bowl, whisk together the flour, xanthan gum (if using), cornstarch, baking powder, baking soda, salt, and sugar.
- Set aside 1 tablespoon of the dry mixture. Toss the blueberries in that flour to coat.
- Create a well in the center of the dry ingredients. Add the wet mixture and mix until just combined. The batter will be thick.
- Gently fold in the floured blueberries until evenly distributed.
- Divide the batter evenly among the muffin cups. Smooth the tops with wet fingers.
- Brush tops with melted butter and sprinkle with coarse sugar, if using.
Bake the muffins
- Bake at 400°F for 10 minutes. Then reduce heat to 350°F and bake for another 10–12 minutes, until a toothpick inserted in the center comes out with a few moist crumbs (avoid testing in a blueberry).
- Finish baking the muffins at 350°F until a toothpick inserted in the center (and not in a blueberry) comes out with no more than a few moist crumbs attached (10 to 12 minutes more).
- Let muffins cool in the tin for 10 minutes before transferring to a wire rack.

Notes
These muffins work best with a well-balanced gluten free flour blend like Better Batter or Nicole’s Best. If using Bob’s Red Mill 1-to-1, add ½ teaspoon extra xanthan gum to avoid a crumbly texture. Avoid Cup4Cup—its updated formula doesn’t perform well here. For DIY blend instructions, visit my all purpose GF flour blends guide. Using frozen blueberries
Don’t thaw them! Use straight from the freezer and toss in dry ingredients before folding into the batter. Dairy free version
Use half plain dairy-free yogurt and half unsweetened non-dairy milk instead of buttermilk. Swap butter for block-style vegan butter (like Miyoko’s, Melt, or Earth Balance sticks).

How to store and freeze gluten free blueberry muffins
Room temperature:
Store fully cooled muffins in an airtight container at room temperature for up to 2 days. Wrap individually in plastic wrap for best texture.
Freezer-friendly:
These muffins freeze beautifully. Place completely cooled muffins on a baking sheet to flash-freeze, then transfer to a freezer-safe container or zip-top bag.
To reheat:
- Toaster oven: For a crisp edge and warm center, sprinkle lightly with water and bake at 250°F for 5 minutes or until warmed through.
- Microwave: Heat a frozen muffin for 30 to 45 seconds at 50% power.
FAQs
Not quite. Buttermilk is thicker and more acidic than milk, which helps create a tender crumb. For the best results, use half plain yogurt or sour cream and half milk as a substitute.
It adds brightness and balances the sweetness. It also enhances the blueberry flavor. You can substitute ½ teaspoon vanilla extract if you don’t have lemon juice.
No—this batter is formulated for muffins. For a gluten free blueberry loaf, try my gluten free blueberry bread.
Yes! Bake at 400°F for 5 minutes, then reduce to 350°F and bake for about 9 more minutes, or until a toothpick comes out clean.
You can refrigerate it in the muffin tin, covered. Let it sit at room temperature for 20–30 minutes before baking for the best rise.
They are gorgeous! I used egg replacer, turned out great. I have most of your cookbooks, but really appreciate the website with the substitution suggestions. It used to be just this was gluten free, now I have discovered a bunch more intolerances.
I’m so glad the substitution suggestions are useful to you, Joey!
I used sweet potato flour istead of potato flour.
The muffin was nothing to write home about for the all the effort. I had to make the mock bake better flour.
I’m afraid that sweet potato flour is not an appropriate substitute for potato flour, Lara. I recommend you try the mock Cup4Cup if you don’t want to buy potato flour.
Love your recipes. They always turn out.
Thank you so much, Elaine. That means a lot to me!
If I use 200 grams of eggs, that would 4 large eggs. Is that correct?
Yes, Shirlene!
It’s a good recipe to make my all time favorite muffins
Can you substitute arrowroot powder for the corn starch?
That should work, Ashley!
You’ve changed my life! Finally, finally a delicious, moist, gluten free muffin with that cakey chewy texture. Absolutely fantastic! (Admit I did substitute for the buttermilk and they still came out perfect)
I’m so glad you have blueberry muffins you love back in your life, Sandi! Thank you for sharing your experience.
I had a box freezer quit on me so I have a bag of frozen blueberries that have already been thawed. Is it unreasonable to think I might be able to make a decent batch of blueberry muffins with them? Do you have any other ideas for a recipe that would work with thawed frozen blueberries?
You definitely cannot make this recipe with defrosted blueberries. You can make these blueberry swirl muffins, actually, though.
Mil gracias, siempre es confiable Shoestring espero me queden muy ricos como mis panes de Shoestring, la gallete, y roles de cena que me encantan
This recipe is great!! Wonderful as is but I used 140 ml of vegetable oil instead of melted butter and it made them even fluffier! I’ve also messed around with different combinations, like raspberry and chocolate chip, which have turned out great as well. Definitely recommend!!
