These sourdough blueberry muffins have an incredible texture and flavor thanks to sourdough discard! My recipe takes just 30 minutes from start to finish and makes a dozen beautiful muffins.
Sourdough Discard Blueberry Muffins
Before I talk about these sourdough blueberry muffins, I think I should admit that I might have a bit of a blueberry muffin obsession. If you’ve been following along, you know that I recently shared a recipe for blueberry muffin cookies that is simply incredible (if I do say so myself). I also have classic blueberry muffins, plus blueberry cream cheese muffins. How many blueberry muffins recipes is too many?
Correct answer: the limit does not exist.
Now back to today’s recipe, which I absolutely love. Not only are these muffins full of blueberries, but they have a truly amazing texture; they are so, so, SO soft and tender. The sourdough discard is a key player in creating this lovely texture, and of course, it also adds a beautiful depth of flavor too.
What to love about this recipe:
- Comes together fast.
- No mixer needed (seriously, please don’t use one!).
- Beautiful tall muffin tops, thanks to my special muffin trick (also used in my banana muffins).
- Amazing flavor and texture from sourdough discard.
What You Need
Most of these ingredients are pretty standard, except for the sourdough discard–obviously! Here are the most important ones:
- Sourdough discard. You should have some of this lying around if you’re feeding an active sourdough starter! If you don’t, check out the FAQ section below.
- Melted butter. Not only does melted butter make this recipe super easy to mix together by hand, but it also yields a buttery flavor too.
- Blueberries. Fresh or frozen blueberries will work here, but just know that frozen berries will dye your batter purple. If I’m using frozen berries, I prefer to thaw and drain them before adding them to the batter.
- Sour cream. Similar to buttermilk, sour cream adds moisture, tenderness, and flavor.
- Room temperature egg. It’s important that your egg is at room temperature so it incorporates easily; otherwise, you might end up over-mixing your batter. If you forget to set yours out ahead of time, read my post on how to quickly bring eggs to room temperature.
SAM’S TIP: For a pretty, bakery style look I recommend sprinkling some extra granulated sugar on top of your sourdough blueberry muffins just before baking. Or, if you’d really like to take your muffins to the next level, skip the sugar and add some streusel!
Remember, this is just an overview of the ingredients I used and why. For the full recipe please scroll down to the bottom of the post!
How to Make Sourdough Blueberry Muffins
- Whisk together the dry ingredients in a large bowl.
- Combine the wet ingredients in a separate bowl.
- Fold the wet ingredients into the dry ingredients until the batter is 50% combined.
- Add the blueberries and keep folding until just combined. Do not over-mix!
- Portion the batter into a lined 12-count muffin tin. I like to use an ice cream scoop for this!
- Sprinkle granulated sugar over the tops (if using) and bake for 8 minutes at 425F.
- Reduce the oven temperature to 350F (don’t open the door!) and bake for an additional 12 minutes or until cooked through.
- Let cool in the pan for 10 minutes, then remove to a cooling rack to cool completely.
SAM’S TIP: Using two oven temperatures ensures our muffins will have a beautiful rise. We’ll start off high, then reduce the temperature (without opening the door!) to finish baking. You’ll see this technique used in most of my muffin recipes, including my bakery style chocolate chip muffins.
Frequently Asked Questions
These sourdough blueberry muffins were carefully designed to be moist and tender, so they should not be dry at all. If yours are, it’s possible that you over-measured your flour (it’s easy to do!), over-mixed your batter, or simply baked them too long.
Over-mixing will doom any quick bread, muffin, or pancake; it makes them dense and dry. To avoid this, make sure you stir everything together by hand (do not use a mixer!) and stop once everything is just combined.
Sourdough discard is actually a byproduct of feeding/maintaining a sourdough starter. Before you feed your starter, you always discard half of what is in the jar. Instead of wasting that discard (it still has lots of nutritional benefits), I like to use it in other recipes, like these muffins or my sourdough crackers or sourdough pancakes.

Yes! Just make sure to wrap them really well in plastic wrap beforehand and store in an airtight container. They’ll keep this way for a few months.
To thaw, you can let your muffins sit at room temperature, or you can microwave them for a few seconds.
The muffin liners I’m using here today are my parchment paper muffin liners! They are so easy to make and instantly elevate the look of your muffins.
Enjoy!

Notes
Blueberries
Frozen blueberries will work but may streak your batter blue/purple. I typically thaw and drain the berries before using.Storing
Store in an airtight container at room temperature for up to 3 days. Muffins may also be tightly wrapped (after cooling) and frozen for up to 3 months.Nutrition

These are the best muffins ever!! Everyone loves them and compliments. I’ve used mixed berry, raspberry and add lemon zest. I’ve also replaced sour cream with yogurt or cottage cheese. These are consistent moist & delicious 😋
love these. ive made several times. the recipe is so easy to follow
So we love raspberries and white chocolate in our house, so we substitute the blueberries with white chocolate chips and frozen raspberries!! The kids absolutely love them and eat them up like crazy!! I love them too!!
These are great, and they’re remained great even when I’ve tried experimented with small modifications (due to being out of an ingredient – or trying to bump up the protein – or whatever). Example: adding a couple scoops of vanilla protein powder, adding a lemon (both the juice and the zest), replacing half the flour with dry oats, replacing the butter with an extra 1/2 C or so of the Greek yogurt). They’ve always turned out great! Glad I found this recipe!
Thanks for sharing this, Trish! We appreciate you using our recipe and coming back to leave a comment 🩷
Glad I came across your blog these muffins were superb. I have a daughter who is gluten free but don’t know how to make a gluten free starter. Is it just the same recipe only using 1:1flour would you have a recipe or maybe Ally can share. Thank you so much
Hi Fran! We honestly don’t know how it would go without trying it ourselves. We typically recommend using a 1:1 flour for making our recipes gluten free, but we aren’t sure how that would go with the starter 🙁
By far the best blueberry muffins I’ve ever made!
Hello. Do you use the discard cold or warm?
Hi Christina! You will want it to be room temperature. 🙂
Thank you so much for the quick response. I’ve made it a couple of times with my sourdough starter and it was delicious. I have some discard in the fridge so I wanted to make sure I did it right. I’ll be making these tonight.
This recipe looks delicious! I can’t wait to try it out! Can gluten-free flour be used instead of all-purpose?
Hi Erica! A 1:1 gluten free flour should work fine here. Enjoy!
How long do you bake them if you make mini muffins?
Hi Tina! I haven’t tried it, but I would think somewhere around 11-13 minutes would work. 🙂
made the muffins and there was to much batter for my muffin cups so I spread the rest on a small cookie sheet and baked it along side the muffins both turned out great but my husband loved the cookie sheet because it was like a giant muffin top. So made a second batch the next day with same instructions and added lemon zest and spread the whole thing out on a big cookie sheet husband loved it so much. Very yummy thank you so much for this amazing recipe.
We’re so happy you enjoyed it, Tina! Love the lemon zest addition 😊
My husband loves blueberries and I am new to having a sourdough starter – safe to say these were a HIT in my home! My husband now asks for these every week!! Such an amazing recipe 🙂
I’m wondering if a gluten free sourdough starter can be used in this recipe? Thank you for all of your wonderful tips & recipes!
We’re so happy you’ve been enjoying the muffins, Ally! We haven’t tried a gluten-free starter with this recipe, but we think it could work. Let us know how it goes 😊
Update – I made a new batch using 1:1 gluten free flour & gluten free starter and they turned out phenomenal! i did not have to change a thing! i will never stray from this recipe!!
Thanks for the update, Ally! We’re so happy it was a success 🎉
I want to make these with bananas…would you change the amount of discard or yogurt because of the wetness of the bananas?
Unfortunately without trying it we can’t say what alterations would need to be made 🙁
So good!!! Just made them and they came out perfect!
Wonderful! Thanks for giving our recipe a try 🥰
Great way to include sourdough in a different way.
best muffins EVER!
I made these using frozen 3 berry fruit blend from costco. Some of the responses to them were: “exquisite”, “best muffins I have ever had in my life”, “please make these again!”
I am so thrilled to hear this, Debi! Thank you so much for trying my recipe, I really appreciate it!!
These were fantastic! I did sub chocolate chips instead blueberries since I didn’t have any but I’m excited to try it with blueberries! I have a tripple batch of sourdough pizza crust in the fridge that I’m excited to try!
I have a wheat berry grinder so any new whole wheat recipies would be wonderful (we love your whole wheat pancake recipie) Also a sourdough focaccia recipie would be great too (savory and sweet)! You really are the best! I love being able to cook from scratch for my family and you’re the reason why I can!
