These Sourdough Lemon Poppy Seed Muffins are soft, moist, and pleasantly tangy. They use sourdough starter discard for lift, bake to a golden top, then get brushed with a bright lemon glaze and a sprinkle of coarse sugar. Quick and easy to make, they’re perfect for brunch, snacks, or a simple breakfast treat.
Do you ever feed your sourdough starter with every intention of baking, then get busy and forget to use it? Don’t toss that discard — it still has wonderful baking potential. These lemon poppy seed muffins use sourdough discard (anywhere from one to a few days old) and turn out incredibly soft with bright lemon flavor and a moist, cake-like crumb.
If you don’t have a sourdough starter yet, it’s simple to make one at home. Once you have discard, this recipe is an excellent way to use it.
You can pair these muffins with other sourdough-discard recipes like chocolate chip cookies, banana muffins, or quick breads when you need ideas for using excess starter.
🍋 Ingredients
These muffins celebrate bright lemon flavor and the visual pop of black poppy seeds—the combination that creates an iconic bakery-style muffin.
Key ingredient notes
- All-purpose flour: Use AP flour for the intended texture; bread flour will change the crumb.
- Sourdough discard: Discard or active starter can be used. If using discard (inactive), this recipe pairs it with baking powder and baking soda for reliable rise.
- Yogurt: Use full-fat yogurt for moist muffins. Sour cream makes an excellent substitute.
- Coarse sugar: Turbinado or another coarse sugar adds crunch on top while the muffins are still warm.

💡 Tips to Make Them Better
- Use fresh lemons: Fresh juice and zest give the best bright flavor; concentrate won’t match the intensity.
- Measure flour properly: Fluff the flour, then spoon it into the measuring cup to avoid compacting and producing a dense muffin.
- Discard age: Discard that is 12–48 hours past feeding works well. I often use starter that has gone two days without feeding and still get a fluffy result.
- Don’t overmix: Combine wet ingredients, fold in lightly beaten eggs, then add to dry ingredients and stir just until incorporated. Overmixing makes muffins dense.
🥣 How to Make
Step 1: Preheat the oven to 375°F (190°C).
Step 2: Prepare a 12-cup muffin pan by greasing it. (Baking directly in a greased pan gives the best results; liners can sometimes stick.)
Step 3: Melt the butter in a small saucepan or microwave and allow it to cool slightly.
Step 4: In a large bowl, whisk together the flour, sugar, poppy seeds, baking powder, baking soda, and salt. Set aside.
Step 5: In a medium bowl, whisk together the sourdough discard, full-fat yogurt, melted butter, vanilla extract, fresh lemon juice, and lemon zest until smooth.
Step 6: Fold in the eggs just until combined.
Step 7: Add the wet mixture to the dry ingredients and mix gently with a whisk or spatula until just combined—do not overmix.
Step 8: Using a cookie scoop or spoon, divide the batter among the muffin cups, filling each about two-thirds full. This recipe yields about 12–15 muffins depending on size.
Step 9: Bake for 20 minutes at 375°F. Check doneness by inserting a toothpick into the center; it should come out clean and the tops should be slightly golden.
Step 10: While the muffins bake, make the lemon glaze: combine granulated sugar and freshly squeezed lemon juice in a small saucepan. Bring to a gentle boil over medium heat, then simmer 3–5 minutes until it begins to thicken into a glaze.
Step 11: Remove muffins from the pan and transfer to a cooling rack. Allow them to cool for a few minutes.
Step 12: Brush the warm muffins with the lemon glaze and sprinkle with coarse sugar (such as turbinado) while the glaze is still tacky for a pretty, crunchy finish.
Recipe FAQs
Can you freeze sourdough lemon poppy seed muffins?
Yes. Allow the muffins to cool completely, then transfer them to a freezer-safe container or bag. Thaw at room temperature or briefly warm in the oven or microwave.
Can I use lemon concentrate?
While concentrate can be used in a pinch, fresh lemon juice and zest provide a far brighter, fresher flavor. The zest especially contributes essential aromatic oils that concentrate lacks.
