Ingredient Notes
You just need a few simple ingredients to make these sourdough blueberry muffins!
- Sourdough Starter - I typically use leftover sourdough discard to make these muffins because I always need to use up extra discard, but ripe sourdough starter works just as well! This recipe uses a little bit of baking powder to help it rise, so the sourdough is just for that tangy flavor.
- Almond flour - Substituting a portion of the flour for almond flour is one of my favorite tricks! It yields tender baked goods with a slightly nutty flavor. But if you prefer, just substitute all purpose flour.
- Greek yogurt - I love adding Greek yogurt to baked goods because it keeps them super moist and tender! You can also use plain full-fat yogurt or sour cream.
- Blueberries - I love using fresh blueberries when they're in season, but frozen blueberries work well too!
- Cinnamon - Just a hint of cinnamon goes so well with the blueberries! But you leave it out if you prefer.
- Sparkling sugar - If desired, sprinkle some sparkling sugar on top of the sourdough blueberry muffins before baking to give your muffins some extra pizazz.
How to Make Sourdough Muffins
Preheat your oven to 400°F and line a muffin tin with muffin liners.
In a small bowl, sift together the flour, almond flour, baking powder, and salt.
Then add about 2 tablespoons of the flour mixture to the blueberries and toss to coat. This helps keep the blueberries from all sinking to the bottom of the muffins.
In a large mixing bowl, whisk together the melted butter, sugar, and brown sugar.
Add in the eggs and vanilla and whisk until combined and smooth.
Then stir in the sourdough starter (or discard) and yogurt and whisk until fully incorporated.
Then fold in the dry ingredients.
Gently fold the blueberries into the batter along with any leftover flour in the bowl.
Spoon the batter into your muffin cups so that they are almost full. Sprinkle sparkling sugar over top of each muffin if desired.
Bake at 400°F for about 25 minutes for regular sized muffins. Rotate the pan about halfway through so that the muffins brown evenly.
Remove the sourdough blueberry muffins and let cool on wire rack.
Tips for the Best Baked Goods
Use room temperature ingredients! Always make sure ingredients like butter, eggs, milk, yogurt, etc. are at room temperature before baking (unless the recipe indicates otherwise)! This ensures they'll incorporate into the batter more easily and leads to overall better texture. Remove all ingredients from the fridge 30 minutes to an hour before baking for best results.
Measure your flour correctly! It's most accurate to use a kitchen scale, but if you're measuring by volume you want to spoon and level! Fluff up the flour a bit with a spoon, and then spoon flour into the measuring cup. Once it's overflowing, use the back of a knife to level it off. Don't ever pack flour into the measuring cup or you'll end up with way too much! Improperly measured flour can lead to dry, dense baked goods. [Measure cocoa powder the same way!]
Use an oven thermometer! Just because your oven says it's 350, doesn't mean it is! If you oven hasn't been calibrated recently, it can be as much as 30 degrees off, which will negatively affect all baked goods from cakes to macarons! An oven thermometer is the easiest/cheapest way to ensure your oven is always at the proper temperature.
Make sure you baking powder is fresh! Baking powder is important for helping baked goods rise properly, but it has a relatively short shelf life once opened, so it's one of the few items I never buy in bulk! To test if your baking powder is still fresh, add a small amount to boiling water. If it bubbles it's still good to use, but if not it's time to toss it!
Recipe FAQ's
These are best eaten the same day. Since the muffins are so moist, they will mold quickly when left at room temperature. Store in an airtight container in the fridge for 2 to 3 days. Pop in the microwave for 15 seconds to reheat!
Yes! I recommend using fresh blueberries if you can but frozen work too! No need to let them thaw before adding to the muffin batter.
Yes! For mini sourdough blueberry muffins reduce the baking time to 15-20 minutes.
Tips for Success!
For best results I always recommend using weight measurements (especially when baking) because it's the most accurate. Kitchen scales are super affordable and also reduce the number of dishes you have to do! However, all my recipes also include US customary measurements for convince. Use this chart to convert measurements for common ingredients!
Substitutions: In all my recipes, I've included substitutions that I know will work, but I cannot guarantee results if you substitute ingredients that I have not recommended. [For example, granulated sugar and honey are indeed both sweeteners but they have very different properties so they can not always be swapped 1:1. Using honey in a cookie recipe that calls for granulated sugar will yield a giant mess.] In the recipe card you'll find links to the specific ingredients/brands that I use.
A note on salt: I almost exclusively use Diamond Crystal Kosher Salt because it's the best all-purpose salt for cooking and baking. If you're not using kosher salt, consult this handy guide for a conversion chart! When in doubt, if you're using table salt just reduce the amount by half for baked goods. When cooking, I prefer to under-salt because you can always add more! If you've over-salted, adding a little bit of acid (like lemon juice) can help.

Oh my gosh! One of the best things I have baked ever! And I bake a ton. I subbed the blueberries for raspberries and white chocolate chips. I used frozen raspberries and broke them up a bit. I baked them at 350 because I knew 400 in my oven would burn them. They are so moist and tender, just perfect. I googled yogurt and discard muffins and these were the only ones. So delighted.
Heather says
Oh if you bake at a lower temp they won’t give you that beautiful dime like a bakery muffin, my oven is just wonky so I had to miss out on that.
Kyleigh Sage says
Raspberries and white chocolate chips sounds so good!! I’m so glad they turned out!!
Destini says
So so so good! Whole family loved them. Thank you! 🫶

Thank you so much for this wonderful recipe. After everything that went wrong for me tonight, I can honestly say this recipe is foolproof. I changed it just a tiny bit, used 1/4 cup butter, 3 Tb Olive oil (rather than all butter) and added some orange zest. I have no oven, so I was using a toaster oven. Well, the door fell off the blasted thing as I was getting ready to put in the muffins. It took me awhile to get it so it would close with some wire, but I was determined to bake the muffins. Then, a breaker tripped, and the power in my kitchen went off! This is at 11 pm at night, mind you. I'm outside with a flashlight, and the breaker will not reset. Window a/c is off (the kitchen feels like it is 150 degrees), fridge/freezer is off, nothing. The kitchen feels like it is 150 degrees, and I'm in a panic. An hour later as the muffins are sitting in the toaster oven, I finally get the breaker to trip back on. The muffins had been sitting in the toaster oven with the broken door. They'd barely started to cook from the residual heat before the breaker tripped. Anyway, despite it all, when the muffins finished cooking, they came out delicious, and even looked like the photos! So, I must say, this is a really great recipe!!! (But some days, it probably doesn't pay to get out of bed!)

I made these, and they were amazing! They came out perfect the first time. My family says this is their new sourdough discard favorite recipe!
Jenny says
These were the very best blueberry muffins I have ever made!!! Absolutely delicious
Virginia says
Delicious and I think what set's them apart is the almond flour. I can't wait to build up some discard so I can make them again.
