Easy Sourdough Blueberry Muffin Recipe (Bakery-Style Domes)
The first time I pulled a tray of sourdough blueberry muffins out of the oven with domes like a proper bakery, I stood there just staring. Tall, golden brown, bursting with juicy blueberries - the end result is hands-down the best blueberry muffins I've baked. The secret is a two-stage bake plus a well-fed active sourdough starter.

This easy recipe is a delicious way to use leftover sourdough starter - a great way (and one of the best ways) to put excess starter to work without a full bread bake. Active starter adds tang that makes the sweet blueberry flavor pop, and the two-stage bake takes the standard blueberry muffin to the next level. A family favorite - I bake a double batch in blueberry season, keep half as an afternoon snack, and freeze the rest. The whole family asks for them by name.

🥘 Ingredients
Dry Ingredients
- All-purpose flour - Structure and tenderness.
- Granulated sugar - Sweetens; caramelizes the tops of the muffins.
- Baking powder and baking soda - Double leavening for consistent lift.
- Salt - Sharpens flavor in the flour mixture.
- Ground cinnamon - Cozy warmth that plays with the blueberry flavor.
Wet Ingredients
- Active sourdough starter (100% hydration) - Fed and bubbly, used 4-8 hours after feeding. This is what makes these fluffy sourdough blueberry muffins stand apart. Leftover sourdough starter or discard works too - slightly denser and tangier.
- Whole milk - A 1-cup milk swap to oat or coconut milk works as a non-dairy option.
- Melted unsalted butter, cooled - So it doesn't cook the eggs.
- Large eggs, room temperature - Room temperature eggs blend smoothly into the muffin batter.
- Vanilla extract - Pure extract.
Mix-Ins & Topping
- Fresh or frozen blueberries - Sweet blueberries in season; frozen blueberries year-round. Never thaw - straight in won't turn the batter purple.
- All-purpose flour for coating - A tablespoon of flour tossed with the blueberries keeps them off the bottom of the muffins.
- Coarse sugar - Turbinado or demerara.
🍽 Equipment
- 12-cup muffin pan
- Large bowl
- Medium bowl
- Whisk
- Silicone spatula or wooden spoon
- Kitchen scale

🔪 Instructions
- Set your preheated oven to 425°F (220°C). Line your muffin pan with paper liners - muffin liners make cleanup easy. Or grease the muffin cups well.
- Toss the blueberries with the coating flour in a small bowl.
- Whisk all dry ingredients in a large mixing bowl until no lumps remain in the flour mixture.
- In a separate medium bowl, whisk the active sourdough starter, milk, melted butter, eggs, and vanilla until smooth.
- Pour the wet ingredients into the dry and fold gently with a silicone spatula or wooden spoon until just combined. A few lumps in the muffin batter are fine - no stand mixer.
- Fold in the coated blueberries with as few strokes as possible.
- After the final fold, cover and leave the dough to bulk ferment at 23°C (73°F) for 4-5 hours, or until it has risen by about 60%. The dough should feel airy and show bubbles on the surface and sides.
- Divide batter among the 12 muffin cups, filling each 90% full. Sprinkle coarse sugar over each.
- Bake at 425°F for 5 minutes - do not open the oven door.
- Without opening the oven, drop to 375°F (190°C). Bake 18-20 minutes more, until the tops are golden brown and a toothpick comes out clean.
- Cool in the muffin tin 5 minutes; transfer to a wire rack.
🥄 Substitutions
- Flour - Up to half whole wheat.
- Butter - Melted coconut oil, avocado oil, or vegetable oil. Greek yogurt or sour cream swap in for some butter.
- Milk - Oat milk or full-fat coconut milk.
- Sugar - Coconut sugar, light brown sugar, or organic cane sugar 1:1. Maple syrup works; reduce milk slightly.
- Blueberries - Raspberries, blackberries, or chocolate chips. Lemon zest in the batter pairs beautifully.
💭 Tereza's Top Tips
Don't open the oven between temperatures - cold air collapses domes. If tops brown faster than centers cook, tent the muffin pan with foil. For a crumb topping instead of coarse sugar, press a mix of butter, flour, and brown sugar over the batter for bakery-style muffins. This sourdough muffin recipe uses a 2-cup sourdough starter portion - a 1-cup sourdough starter pour plus extra milk works in a pinch.
🥣 Storage
Store in a single layer in an airtight container at room temperature up to 2 days, lined with a paper towel. For longer storage, refrigerate up to a week. To freeze, wrap each in plastic wrap then foil - up to a month. Thaw overnight, microwave 12-15 seconds, and you're back to perfectly moist muffins.
🧂FAQ
Yes. Sourdough discard blueberry muffins will be slightly denser and tangier. The baking soda and baking powder still provide lift. Blueberry sourdough discard muffins are a good choice when you haven't fed your starter - using leftover sourdough discard avoids waste.
You skipped the flour coat or the batter was too thin. Tossing fresh blueberries or frozen blueberries in a tablespoon of flour before folding them in keeps them suspended.
Fill the muffin cups to 90% and use the two-stage bake: 5 minutes at 425°F, then drop to 375°F without opening the oven. The initial heat creates the dome before the crust sets.
A tablespoon of lemon juice and a teaspoon of lemon zest in the wet ingredients gives a lemon-blueberry version. A simple lemon glaze (powdered sugar, lemon juice, milk) drizzled over cooled muffins takes it further.
Fill mini muffin cups about ¾ full and reduce baking time to 12-15 minutes. Toothpick test.

I've tried a lot of blueberry muffin recipes and this one is the best so far. The tops came out perfectly domed on my first try and the blueberries were so juicy inside. Not going back to regular muffins after this!
