This sourdough blueberry muffins are soft, sweet, tender and moist! They taste just like a bakery blueberry muffin but homemade in less than an hour.

When life gives you leftover sourdough starter, don’t toss it! Use it to make sourdough blueberry muffins, which are legitimately my new favorite blueberry muffin from scratch. You can, and should, also make sourdough cinnamon rolls, sourdough waffles and sourdough pancakes, but we are here about these muffins!
Just like my banana bread muffins and chocolate chip banana muffins, these are soft but dense muffins that hold their shape and don’t crumble when you bite into them. These muffins that are bursting with fresh berries in their tender centers but have that ever-so-crisp edge at the top.

Why You Will Love this Blueberry Muffin Recipe
- The texture & flavor you love in a bakery blueberry muffin: Every bite of these muffins is soft, moist, tender, and full of blueberry flavor with a hint of crunch from a demerara sugar topping.
- The sourdough starter is here for moisture and nothing else. This recipe does not rely on sourdough starter to raise the muffin tops, because that makes for tough and (not delightfully) chewy muffins.
- Better than bakery blueberry muffins in under an hour. We let baking soda do the heavy lifting so you get fast, flavor blueberry sourdough muffins in almost no time at all!
- Lightly sweetened with maple syrup or honey. No processed sugars in these muffins! Feel good about serving them for breakfast with peaches and cream overnight oats or a tropical protein smoothie!

Pro Tips for Making Tender Sourdough Blueberry Muffins
- Don’t overmix the batter. This is a cardinal rule for all muffins and it keeps the muffins from becoming tough. Mix the ingredients until they’re just – and I mean just – combined, and you’ll get muffins so soft and fluffy, you’ll want to use them as a pillow.
- Don’t be tempted to use only all-purpose flour for this recipe; the combination of flour and almond flour is what gives these muffins their softness and light texture especially in spite of the sourdough starter.
- Top these muffins with demerara sugar for crunch. This easy addition add extra crunch and sweetness just like in my taller-than-life lemon poppy seed muffins and gingerbread loaf.
- Paper liners will keep the muffins moist for longer. You could bake these directly in muffin tins sprayed with non-stick cooking spray, but muffins baked in liners retain moisture better than those without especially when freezing.
Ingredients & Substitutions
- All-Purpose Flour
- Almond Flour: The combination of almond flour and all-purpose flour keep these muffins light and tender. If you can’t use almond flour, use 1 1/2 cups all-purpose flour and 1/2 cup fine cornmeal.
- Baking Soda: Since baking soda is the one doing the leavening in these muffins, you’ll want to make sure it is fresh. It is going to react powerfully with the acid in the sourdough starter for tall, proud muffins!
- Ground Cinnamon
- Salt
- Sourdough Starter: You can use active fed starter or sourdough discard for this recipe. It does add moisture to the muffins but the baking soda is doing the heavy lifting! If you don’t have a sourdough starter lying around, let me introduce you to my blueberry lemon muffin bread, which is essentially a blueberry muffin baked in loaf pan! You could also make these jumbo blueberry muffins. If you are just starting your journey, I suggest you start with my sourdough starter recipe then read the ins and outs of how to feed sourdough starter. Practice makes perfect, so you will also have enough discard to make sourdough cinnamon rolls and sourdough focaccia!
- Maple Syrup or Honey: If you want sweeter muffins, use honey.
- Milk: The milk that you choose will impact the flavor and texture of any muffins. I love the results when I use dairy milk, especially whole milk or buttermilk, but I often choose unsweetened almond milk to reduce the calories.
- Vegetable Oil: You can use melted unsalted butter or melted coconut oil in place of vegetable oil. Butter lends the best flavor but muffins made with oil are the most moist and will retain that moisture longer just like these incredibly moist pumpkin muffins!
- Large Egg
- Blueberries: You can use either fresh blueberries or frozen blueberries in these muffins. Make some blueberry shortcake next!
- Demerara Sugar: The demerara sugar adds extra crunch and sweetness on top. You can omit it or use coarse sparkling sugar or turbinado if desired. You could also add a crumb topping like my coffee cake muffins.
See the recipe card for full information on ingredients and quantities.
Some Possible Variations
- Add a little spice or extract: Swap out the ground cinnamon for a mixture of spices like in my gingerbread pancakes! You could add a teaspoon vanilla extract or ¼ – ½ teaspoon almond extract or another family favorite.
- Bring in the citrus! Blueberries are best friends with lemon and orange for a reason! Add a grate of lemon zest or orange zest alone or with a bit of extract! You could add a little lemon juice but if you want the full lemon experience add blueberries to my lemon poppy seed muffins instead.
- Go berry wild! Get crazy like I do with my berry cream cheese coffee cake recipe! Substitute the blueberries for raspberries or blackberries, or make a mixture of all three!
- Swap the sugar for streusel! Make this easy streusel topping recipe and crumble over the muffins before baking. Just don’t add too much, or it will weigh them down and the centers will sink!

Frequently Asked Questions
Let muffins cool completely at room temperature then store them in an airtight container or resealable plastic bag at room temperature for up to 4 days; in the refrigerator for up to a week; or frozen for 2 months.
In this sourdough muffin recipe, the sourdough starter helps make the muffins more moist in addition to the vegetable oil and milk. The blueberries also add moisture and keep them moist for longer. Other ingredients that can add moisture to muffins are sour cream, buttermilk, Greek yogurt, coconut oil and other add ins.
After 4 days I would recommend refrigerating blueberry muffins, but I prefer to freeze any that I know I will not consume within 2 days, so that they stay fresh and moist longer! This is especially true of very moist muffins with blueberries and buttermilk, which can spoil at room temperature after 3 days.

Notes
- Recipe adapted from King Arthur Flour.
- Don’t be tempted to use only all-purpose flour for this recipe; the combination of flour and almond flour is what gives these muffins their softness and light texture. If you can’t use almond flour, use 1 1/2 cups all-purpose flour and 1/2 cup fine cornmeal.
- You can use leftover sourdough starter that’s fed or unfed–totally up to you! The flavor of the starter doesn’t really come through in the muffins, so the point is really to use up starter that you don’t want to toss!
- Variations – Add vanilla extract, almond extract, different spices, lemon or orange zest, or change up the fruit! Try blackberries or raspberries, or a mix of all three!
- Storage – Let muffins cool completely at room temperature then store them in an airtight container or resealable plastic bag at room temperature for up to 4 days; in the refrigerator for up to a week; or frozen for 2 months.

On that note, I leave you to these soft, moist, tender, flavorful, totally life-changing blueberry muffins. I encourage you to give my sourdough bread recipe a try and peruse all my sourdough recipes for your next baking adventure!
These were great! Repeat for sure
I tried this recipe last weekend and it was just amazing! The muffins are fluffy, super moist, with juicy blueberries inside. And the sourdough really makes the difference with a regular muffin recipe (I used my sourdough starter than we’ve been keeping alive since… 1990!). Really, these muffins are perfection. I could not recommend them enough! I already shared the recipe around me 🙂 Del
These were amazing and healthy! They froze perfectly and still tasted fresh when thawed a month later. My husband even loved them, and he is PICKY when it comes to muffins! Thanks for a great new sourdough recipe.
As others have said, these were fantastic! I used blueberries and raspberries, which I tossed in a bit of the flour mixture before adding so they wouldn’t all sink. Texture was light, flavor just right. Is there a substitute for the sourdough discard, or a similar recipe, so my friends who don’t bake bread can make these?
Plus they came together quickly! Took less than an hour, start to finish, once my starter was ready (I only keep a small amount so needed to make more).
Marlene, Thank you so much! As for a non-sourdough discard, I would recommend looking at other muffin recipes on my site or finding a blueberry muffin recipe that doesn’t use starter for your friends to use, as this recipe really works best with the discard involved.
Love this simply and healthy discard recipe! My muffins turned out so fluffy!
OMG !! these muffins turned out FANTASTIC. I did not have honey or maple syrup so i added 3/4 cup of sugar. All the muffins were swiped off in a day. Making another batch tomorrow. Thank you so much for this delicious recipe ?
Wonderful recipe! Tasted like it came straight from the bakery. Don’t sleep on the Demerara sugar, gives a great crunch.
What a great recipe! So easy to make and muffins come out looking exactly like the picture. Thank you. Will definitely make again.
Loved these muffins – tons of fruit, more nutrition with the almond flour, super moist and my batch made 16! Very happy and can’t wait to make again! TYSM
Delicious….made them with butter. Thank you.
