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.
Preheat oven to 425F (220C) and line a 12-count muffin tin with paper liners. Set aside.
In a large mixing bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
1 ½ cups(187g) all-purpose flour, 1 cup(200g) granulated sugar, 2 teaspoons baking powder, ½ teaspoon baking soda, ½ teaspoon table salt
In a separate mixing bowl, whisk together melted butter, sourdough discard, sour cream, egg, and vanilla extract until ingredients are evenly mixed.
½ cup(113g) unsalted butter, ½ cup(105g) sourdough discard, ¾ cup(180g) sour cream, 1 large egg, 1 teaspoon vanilla extract
Add wet ingredients to dry and use a spatula to gently fold together. Once batter is about 50% combined, add blueberries and continue to mix, gently, until blueberries are well-distributed and batter is just combined. Do not over-mix or muffins will be dense and dry.
1 ½ cups(210g) fresh blueberries
Evenly divide batter into prepared muffin tin. If desired, sprinkle with granulated sugar.
Granulated sugar for topping
Transfer to center rack of 425F (220C) oven and bake for 8 minutes, then, without opening the oven door, decrease oven temperature to 350F (175C) and bake for 12 minutes longer/until muffins are baked through. The tops will be beginning to turn a light golden brown and a toothpick inserted in the center should come out clean or with moist crumbs.
Allow muffins to cool for 10 minutes in the muffin tin before carefully removing to a cooling rack to cool completely.
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.
