Step by step sourdough blueberry muffins
Make the muffin batter
Start by preheating your oven to 400 degrees with the rack in the center.
We going to mix up the sugar, oil, and egg in a large mixing bowl that will eventually hold all the muffin batter. A hand mixer on medium speed for just a few minutes is perfect.
Then, in a separate smaller bowl, combine the flour, salt, and baking powder.
Add half of the dry ingredients to the sugar mixture, then add the milk, then the rest of the dry ingredients. Stir in the sourdough starter, and finally add the blueberries. Don’t over mix, just gently stir until everything is combined.
(The batter will be thick! This is normal and helps you bake the most tender, fluffy sourdough blueberry muffins!)
Making the topping and baking
Now we make the streusel topping! Begin with the diced butter and cut it into the flour, until you have pieces the size of peas. If you have some bigger bits in there, no big deal. Then stir in the sugar and cinnamon.
Scoop the batter into a muffin tin, filling each cup about 2/3 of the way full. Sprinkle the topping on top, and bake!
Your blueberry muffins are done when a toothpick inserted into the center comes out clean. They will take anywhere from 17-23 minutes.
Take the muffins out of the muffin tin and let them cool on a wire rack. You can eat them warm or room temperature. They will stay fresh for two days just on a plate, covered with plastic wrap.
One of the best things about muffins is you can make them ahead and freeze them. Just make sure they are totally cooled and pop them in a zippered freezer bag. They’ll keep well for a few months!

OMG – just made a batch of these and as I did not have any blueberries, I substituted them for frozen fresh cranberries left over from Christmas. They are delicious and I love being able to use up sourdough discard. This will definitely be my go to recipe in the future. Thank you for sharing your recipe.

Lyn I am so glad you enjoyed them and thank YOU for the idea of adding cranberries to the muffins! Great idea 🙂
We made 5 times this recipe as we have an XXL family and were planning to give some away as thank yous.
Though the batter looked gorgeous, I’m going to admit that I was a little nervous when I first tasted tested the batter and thought that the muffins were going to end up tasting too sourdoughy and might be a scratch. But… I knew I had already used a metric ton of blueberries so I decided I might as well just go ahead and full send it.
They smelled A-MAZ-ING while they were baking and ended straight up, probably being the best blueberry muffins our family has ever eaten! Which says a lot for our family. Good job!
yay! this makes me so happy to hear! i get what you mean about the batter. whenever i bake with buttermilk i think the same thing but it ends up being okay.
Yep, our family has decided that we pretty much always absolutely MUST have these on hand!
I made these yesterday and they were so good! I only got 7 large muffins and they were gone before I turned around. You definitely need to line with paper cups, I didn’t and it was tricky getting them out even though I sprayed the pan. Thank you for the wonderful recipe!
Sharon Ii’m so happy the muffins were a success! I will add a note to use liners for sure!
