Perfect Pairings
These muffins shine brightest alongside a steaming cup of coffee or tea for breakfast. Serve them slightly warm with a pat of European butter melting into the tender crumb. They also make wonderful afternoon snacks paired with fresh fruit and yogurt.
Delicious Adaptations
Switch up your muffin game by incorporating different fruits like raspberries or blackberries. For a tropical twist, add shredded coconut and diced mango. Create a savory version by omitting sugar and adding herbs, cheese, and ham.

Store these treasures in an airtight container at room temperature for three days. For longer storage, freeze individually wrapped muffins for up to three months. Refresh them in a warm oven for that fresh-baked taste.

After years of baking these muffins, I can confidently say they're one of the most reliable and delicious ways to use sourdough discard. The combination of tangy sourdough and sweet blueberries creates something truly special that connects us to the timeless tradition of home baking.
Frequently Asked Questions
- → Can I use frozen blueberries instead of fresh?
- Yes, you can use frozen blueberries! No need to thaw them - just add them frozen directly to the batter. This helps prevent the color from bleeding too much.
- → How do I store these muffins?
- Store the muffins in a loosely covered container at room temperature for up to 3 days. For longer storage, wrap them individually in plastic wrap and freeze for up to 3 months.
- → What if I don't have sourdough starter?
- While sourdough starter adds great flavor, you can replace it with an equal amount of sour cream or Greek yogurt plus 2 tablespoons of flour to maintain the right consistency.
- → Why coat the blueberries in flour mixture?
- Coating the blueberries in the flour mixture helps prevent them from sinking to the bottom of the muffins during baking.
- → Can I make these muffins ahead of time?
- Yes! You can make the batter the night before and refrigerate it. Just bring it to room temperature before baking. The crumb topping should be made fresh just before baking.
