Sourdough Blueberry Muffins Ingredients
Unsalted Butter: I always bake with unsalted butter. Unsalted butter allows me to control the flavor in my baked goods — there is no standard for the amount of salt in salted butter, which makes using salted butter a little unpredictable.
Vegetable Oil: A combination of butter and vegetable oil keep these sourdough blueberry muffins moist and flavorful.
Buttermilk: tenderizes the gluten
Sourdough Discard: In order to avoid a stronger sourdough flavor, use 100% hydration sourdough discard that is no more than a day or two old. You can use fresh, bubbly sourdough starter or refrigerated discard.
Sugar: Granulated sugar gives the perfect sweetness that complements sweet/tart blueberries.
Eggs: Eggs add richness and structure to these muffins.
All Purpose Flour: All purpose flour works well for this recipe. Be careful not to over-mix so the crumb stays tender and soft.
Cornstarch: Cornstarch in small amounts creates a more tender muffin. I love adding it into these blueberry sourdough muffins.
Blueberries: I love these muffins with fresh blueberries. You can also use frozen blueberries if desired. Use them frozen and don’t let them defrost. Coat the blueberries in flour mixture before adding the liquid ingredients.
Mixing Sourdough Blueberry Muffin Batter
Don’t let this long list of ingredients scare you off! They are all necessary and work together to create the most tender and delicious bakery-style sourdough blueberry muffins.
Liquid Ingredients: Mix together the liquid ingredients. Melt unsalted butter in a large liquid measuring cup or small bowl. Add vegetable oil, buttermilk, egg, vanilla extract and sourdough discard. Mix in granulated sugar and stir to combine.
Dry Ingredients: To a separate mixing bowl, whisk together the all purpose flour, baking powder, cornstarch and salt. Add the blueberries and mix together until blueberries are coated in flour mixture. This helps the blueberries suspend throughout the muffins instead of having them all sink to the bottom of the muffin.
Mix Together: Add the liquid ingredients to the flour/blueberry mixture and stir gently a few times until thoroughly moistened. Be careful not to over-mix the dough. This keeps gluten strands from developing. A few streaks of flour are okay!

Make Parchment Paper Liners
If you really want bakery-style liners, you can make your own from parchment paper. Cut the parchment paper into a square a little bigger than the holes of your muffin tins. Place a piece of cut parchment over the hole of the muffin tin. Place a scoop of muffin batter on top of the parchment paper and let it drop down into the muffin well. Repeat with the remaining muffin batter. These muffins bake up beautifully with the parchment muffin liners and look like they’ve come out of a fancy bakery. If you don’t want to use a liner, spray the muffin tin with cooking spray instead.
Baking Sourdough Blueberry Muffins
Preheat the oven to 425 degrees Fahrenheit. Sprinkle a little bit of granulated sugar on the tops of the muffin batter. This gives the muffins their signature crunchy topping. Bake muffins for about 5 minutes at 425 degree F. This is the key to that high domed bakery-style muffin top. Then reduce the temperature to 350 degrees F and bake for another 18-20 minutes until baked all the way through. Check with a toothpick if needed. Let muffins cool completely (or mostly) before enjoying.
Frequently Asked Questions
How do you store leftover muffins?
After the muffins have cooled completely, stick them in an airtight container or ziplock bag. Freeze them for up to 3 months.
What substitutions can I make in these muffins?
You can substitute chocolate chips or any other flavor of baking chips for blueberries. If you want to substitute for the buttermilk, use a combination of milk and sour cream (1/4 cup milk with 1/4 cup sour cream mixed together).
Do I need to use a muffin liner for these muffins?
You don’t have to if you have good quality muffin tins. I like to spray my muffin tins with cooking spray if I’m not using muffin liners.
Have you ever added lemon zest to these?
I haven’t, but I think it would be a great addition to these muffins. I would add the zest of one large lemon to these muffins and maybe add a lemon glaze. Yum!
