When I was little in my grandma's kitchen, I watched her save sourdough discard like it was treasure. She'd always keep it for these muffins, saying it was her hidden trick for making the softest breakfast goodies.
Tasty Companions
These muffins taste best with a hot cup of coffee or tea at breakfast time. Try them slightly warm with a bit of good butter melting into the soft center. They're also great as snacks paired with some fresh fruit and a dollop of yogurt.
Tasty Twists
Mix things up by trying other fruits like raspberries or blackberries instead. For something different, mix in some coconut flakes and chopped mango. You can even make them savory by skipping the sugar and adding herbs, cheese and bits of ham.
Storing Your Goodies
Keep your muffins in a sealed container at room temperature for up to three days. If you want them to last longer, wrap each one separately and freeze for up to three months. Warm them in the oven when you're ready to enjoy that just-baked goodness again.

After baking these muffins countless times, I can tell you they're one of the most foolproof and yummy ways to use up sourdough discard. The combo of tangy sourdough with sweet blueberries creates something truly special that connects us to the old tradition of baking from scratch at home.
Frequently Asked Questions
- → Can I use frozen berries instead of fresh ones?
- Absolutely! Toss frozen blueberries straight into the batter without thawing. This keeps their color from bleeding too much.
- → What's the best way to keep these muffins fresh?
- Keep them in a loosely covered container at room temperature for up to three days. For longer freshness, wrap each muffin in plastic and freeze for up to three months.
- → What can I do if I don’t have sourdough?
- No worries! Swap out the sourdough starter with equal parts sour cream or Greek yogurt, and add 2 tablespoons of extra flour to keep the right batter texture.
- → Why should I cover blueberries in flour first?
- Tossing blueberries in a bit of flour stops them from sinking to the bottom of your muffins while baking.
- → Can I prep these muffins in advance?
- You sure can! Keep the batter in the fridge overnight, then let it come back to room temperature before baking. Make the crumb topping fresh when you're ready to bake.
