Ingredients You’ll Need (And Why)
What makes these muffins really shine:
- Sourdough discard or active starter adds tangy flavour complexity and keeps the crumb tender and moist. You can leave the muffins uncovered at room temperature, and they’ll still be soft three days later! No starter yet? Learn how to make a sourdough starter from scratch (it’s easier than you think, I promise!). Alternatively, ask in a local Facebook group, check with a nearby bakery, or purchase dehydrated starter online.
- Lemon zest & juice: Zest rubbed into sugar releases essential oils for maximum flavor; juice adds brightness and reacts with baking soda for lift.
- Sour cream Contributes richness and a tender crumb.
- Blueberries: Fresh or frozen, they add juicy bursts of fruity flavour.
- Crumble topping with melted butter, flour, sugar, and a pinch of nutmeg creates a crunchy, spiced topping.
Pro Tip
If using frozen blueberries, mix them into the batter straight from the freezer and bake immediately to minimize bleeding.
How to Make Sourdough Blueberry Lemon Muffins
Step 1: Make the Crumble Topping
- Whisk together flour, sugar, and nutmeg.
- Add melted butter and stir until large crumbs form.
- Refrigerate or freeze while preparing the batter.
Step 2: Prep the Muffin Batter
- Rub lemon zest into sugar until fragrant.
- Whisk in sourdough discard, sour cream, lemon juice, eggs, and vanilla.
- In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
- Combine wet and dry ingredients until just mixed.
- Gently fold in blueberries.
Pro Tip
Use a blue (2 oz) cookie scoop or ¼-cup measuring cup to make sure each muffin gets the same amount of batter.
Step 3: Assemble and Bake
- Divide batter evenly into muffin cups.
- Top each with a generous amount of crumble topping.
- Bake at 425°F (220°C) for 5 minutes, then reduce to 350°F (175°C) and continue baking until a toothpick comes out clean.

Tips for Bakery-Style Sourdough Blueberry Lemon Muffins
- Rest the batter: Let it sit for 15–30 minutes before baking for taller muffins. Skip this tip if using frozen blueberries, which need to be baked immediately after being added to the batter.
- Don’t overmix: A few lumps are okay; overmixing can lead to dense muffins.
- Use an oven thermometer: Ensure accurate temperature for even baking.
- Rotate the pan: Turn halfway through baking to promote even rise and browning.
Pro Tip
Leave the batter in the fridge overnight. Some fermentation will take place, which will make the flavour and texture even better!
Flavour Variations
- Berry swap: Use raspberries or blackberries instead of blueberries.
- Add poppy seeds: Stir in a tablespoon for a lemon-poppy-blueberry twist.
- Cranberry Orange: Replace blueberries and lemon with fresh cranberries and orange zest and juice for a wintery version.
Make-Ahead and Storage
- Room temperature: Store uncovered or in an airtight container for up to 3 days.
- Freeze baked muffins: Cool completely, then freeze in an airtight container for up to 3 months.
- Freeze unbaked batter: Portion into muffin cups, add crumble topping, and freeze. Bake from frozen, adding a few extra minutes to the baking time.

FAQs
Yes! Both work well. Active starter may slightly alter the texture due to its stronger gluten structure.
Possible reasons include overmixing, expired baking powder, or underbaking. Ensure fresh leavening agents, mix until just combined, and verify oven temperature with a thermometer.
Absolutely. For best results, bake one tray at a time. If using a convection oven, you can bake both trays simultaneously—just rotate them halfway through. You could also freeze the second tray of portioned muffin dough to bake from frozen later!

Bakery-Style Sourdough Blueberry Lemon Muffins
Ingredients
Method
- To a medium bowl, add 38 g all-purpose flour, 55 g granulated sugar, and ⅛ teaspoon freshly-ground nutmeg. Whisk to combine, then pour over 28 g unsalted buttermelted. Stir together until combined and large crumbs form. Cover with plastic wrap (or place in an airtight container) and place in the fridge or freezer while you make the batter. You want the the butter to firm up before you use the crumble, so it stays in nice chunky pieces while the muffins bake!
- Preheat the oven to 425˚F (220˚C). Line a standard muffin pan with paper liners. To a large mixing bowl, add 250 g all-purpose flour, ¾ teaspoon fine sea salt, 1¾ teaspoon baking powder, and ¼ teaspoon baking soda. Whisk together to combine.
- To a medium mixing bowl or measuring cup, add 160 g granulated sugar and zest of 1 lemon. Using your fingertips, rub the lemon zest into the sugar until the sugar resembles damp sand and smells intensely lemony.
- Add 80 g sourdough discard, 105 g whole milk, 55 g unsalted butter (melted), 60 g neutral-flavoured oil, 50 g sour cream, 2 large eggs, 1 tablespoon lemon juice, and 1 teaspoon vanilla extract to the lemon-infused sugar. Whisk to combine.
- Add the wet ingredients to the dry ingredients, and stir until just combined. Add 175 grams blueberries and fold in gently until evenly distributed.
- Use a blue cookie scoop (2 ounces or ¼ cup) to portion the batter evenly into the lined cups of the muffin pan. Sprinkle on a generous portion of crumble on top of each muffin. Bake for 5 minutes, then lower the oven temperature to 350˚F (175˚C) and bake another 15-25 minutes or until a toothpick inserted into the center comes out clean. When testing with a toothpick, try to avoid hitting any blueberries which will leave residue on the toothpick and make it difficult to see if the muffins are done baking.
- Let the muffins cool in the baking pan for 5-10 minutes, then transfer to a wire rack to cool completely. Muffins can be stored uncovered at room temperature for up to 3 days, or frozen in an airtight container or bag (after they've completely cooled) for up to 3 months.
