How to Make Sourdough Blueberry Lemon Poppy Seed Muffins Recipe
Step 1: Preheat and Prep
Start by heating your oven to 375°F (190°C). Line your muffin tin with paper liners to make sure your muffins come out cleanly and look inviting. This simple step sets you up for easy baking and easy cleanup.
Step 2: Combine the Dry Ingredients
In a large bowl, whisk together the all-purpose flour, baking powder, baking soda, poppy seeds, and salt. Mixing these first ensures they are evenly distributed and helps with a smooth batter later on.
Step 3: Make the Aromatic Sugar Mixture
In a separate bowl, blend the sugar with lemon zest until it smells heavenly. This step unlocks the lemon’s oils and infuses the sugar with citrus flavor, making the muffins wonderfully fragrant.
Step 4: Mix the Wet Ingredients
To that zesty sugar, add sour cream, sourdough discard, melted butter, lemon juice, eggs, and vanilla extract. Whisk everything together until silky smooth and well combined. This rich mixture is what will keep your muffins moist and flavorful.
Step 5: Combine Wet and Dry, Add Blueberries
Slowly fold the dry ingredients into the wet mixture to avoid overmixing, which can toughen the muffins. Gently incorporate the fresh blueberries last so they don’t break apart, giving you those pretty pops of color and flavor inside.
Step 6: Prepare the Crumble Topping
Mix brown sugar, white sugar, flour, cinnamon, and a pinch of salt. Cut in the cold butter until the mixture resembles coarse crumbs. This topping adds that perfect sweet and crunchy contrast to the soft muffin below.
Step 7: Bake to Golden Perfection
Fill your muffin cups about two-thirds full with batter, then sprinkle the crumble topping evenly over each. Bake in your preheated oven for about 14 minutes or until golden and a toothpick inserted in the center comes out clean. Let them cool slightly before moving on to glazing.
Step 8: Glaze with Lemon
Whisk powdered sugar together with lemon juice until smooth and glossy. Drizzle this glaze over the warm muffins for an irresistible finish that adds sweetness and a little tangy zing.
How to Serve Sourdough Blueberry Lemon Poppy Seed Muffins Recipe

Garnishes
A fresh sprinkle of extra lemon zest or a few whole blueberries on top of the glaze brightens presentation and adds an extra pop of flavor before serving. If you’re feeling indulgent, a small dollop of whipped cream or mascarpone pairs beautifully.
Side Dishes
These muffins shine alongside a cup of freshly brewed coffee or a chilled glass of milk for a classic pairing. For brunch, serve them with scrambled eggs or a simple green salad to balance the sweetness.
Creative Ways to Present
For a charming brunch spread, arrange the muffins on a wooden board lined with fresh mint leaves and lemon slices. You can even slice them open and add a smear of honey butter or cream cheese for an extra special touch that your guests will adore.
Make Ahead and Storage
Storing Leftovers
Keep leftover muffins in an airtight container at room temperature for up to two days to maintain their moistness. Beyond that, refrigeration helps, but be sure to warm them slightly before enjoying to refresh their texture.
Freezing
These muffins freeze beautifully! Wrap each muffin tightly in plastic wrap then store in a freezer-safe bag or container for up to three months. Thaw overnight in the fridge or at room temperature for best results.
Reheating
For a just-baked feel, pop frozen or refrigerated muffins into a 350°F (175°C) oven for about 5-7 minutes or microwave for 20-30 seconds. The glaze will soften and the muffin will regain its lovely tender crumb.
FAQs
Can I use frozen blueberries in this Sourdough Blueberry Lemon Poppy Seed Muffins Recipe?
Absolutely! Just be sure to toss them in a bit of flour before folding into the batter to prevent them from sinking and staining the batter too much.
What can I substitute for sourdough discard if I don’t have any?
You can replace sourdough discard with an equal amount of buttermilk or plain yogurt to maintain the tangy flavor and moist texture, though the muffins won’t have quite the same depth that sourdough gives.
Is it necessary to use both baking powder and baking soda?
Yes, using both helps the muffins rise properly. The baking soda reacts with the acidic sourdough and lemon juice, while baking powder provides extra lift for a fluffy texture.
How do I avoid the blueberries sinking to the bottom?
Gently fold the blueberries into the batter at the very end, and coating them lightly with flour helps suspend them evenly while baking.
Can I make these muffins vegan?
With some tweaks like using flax eggs, dairy-free yogurt or sour cream, and vegan butter, you can adapt the recipe — though the texture and flavor will differ slightly from the classic version.
Final Thoughts
This Sourdough Blueberry Lemon Poppy Seed Muffins Recipe is such a delightful way to bring sunshine and sourdough magic right into your kitchen. Once you try these muffins, their perfect balance of tang, fruitiness, and sweet crunch will have you baking them again and again.
