These Blueberry Lemon Poppy Seed Sourdough Muffins are a burst of flavor! With juicy blueberries, zesty lemon, and a sprinkle of poppy seeds, they’re perfect for breakfast or a snack.
They make your kitchen smell amazing as they bake, and trust me, you won’t be able to resist grabbing one right out of the oven! I love enjoying them with a cup of coffee—it’s the best start to my day!
Key Ingredients & Substitutions
Sourdough Starter: Using an active and bubbly starter gives your muffins great flavor. If you don’t have sourdough, you can use plain yogurt or buttermilk to keep the moisture, but you’ll lose some tanginess.
Blueberries: Fresh blueberries are delicious, but if they aren’t in season, frozen blueberries work just fine. Just remember not to thaw them to avoid a purple mess in your batter!
Lemon Zest and Juice: Fresh lemon zest is ideal for that bright flavor. If you can’t find fresh lemons, bottled lemon juice can work, but the flavor won’t be as vibrant. I always prefer using fresh whenever I can!
Poppy Seeds: These add a nice crunch and look pretty too! If you don’t have poppy seeds, you can leave them out or try chia seeds as an alternative for added texture.
How Do I Ensure My Muffins Are Fluffy and Not Dense?
The key to fluffy muffins lies in how you mix the batter. Mixing too much can lead to dense muffins. Here’s how to avoid that:
- Gently fold in the dry ingredients to the wet ingredients. A few lumps are okay—this means you won’t overmix!
- Incorporate the blueberries gently to prevent crushing them, which can also make your muffins dense.
- Be sure to fill the muffin cups about 3/4 full to allow them to rise nicely without spilling over.
Keep these tips in mind, and you’ll have light and fluffy muffins every time! Enjoy baking and sharing these delightful treats!
Blueberry Lemon Poppy Seed Sourdough Muffins
Ingredients
- 1 cup sourdough starter (active and bubbly, can be unfed or discard)
- 1 large egg
- 1/2 cup sugar
- 1/4 cup vegetable oil or melted butter
- 1/2 cup milk (dairy or plant-based)
- 1 tablespoon lemon zest (from about 1 lemon)
- 1 tablespoon fresh lemon juice
- 1 1/2 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 2 tablespoons poppy seeds
- 1 cup fresh blueberries (can use frozen, do not thaw)
For the glaze:
- 1/2 cup powdered sugar
- 1-2 tablespoons lemon juice (adjust for desired consistency)
Time Needed
This recipe takes about 15 minutes of prep time and 20-25 minutes of baking time. After baking, you’ll want to let them cool for about 10 minutes before glazing. So, overall, you’re looking at about 45 minutes until you can enjoy these delicious muffins!
Step-by-Step Instructions
1. Preheat the Oven.
Start by preheating your oven to 375°F (190°C). This way, it will be hot and ready to bake your muffins. While the oven heats up, line a 12-cup muffin tin with paper liners or grease the cups with a little bit of oil or butter.
2. Mix the Wet Ingredients.
In a large mixing bowl, whisk together the sourdough starter, egg, sugar, oil (or melted butter), milk, lemon zest, and lemon juice until everything is smooth. This mixture should be nice and creamy and smell amazing thanks to the lemon!
3. Combine the Dry Ingredients.
In a separate bowl, sift together the all-purpose flour, baking soda, baking powder, salt, and poppy seeds. This step helps to evenly distribute the baking powder and soda for fluffy muffins.
4. Combine Wet and Dry Ingredients.
Now, gently add the dry mixture to the wet mixture. Use a spatula to fold the ingredients together. Be careful not to overmix; it’s okay if the batter is slightly lumpy—this will help keep your muffins light and fluffy!
5. Add the Blueberries.
Time to add those delicious blueberries! Gently fold them into the batter, making sure not to crush them. You want those lovely berries whole so everyone can enjoy them!
6. Fill the Muffin Cups.
Divide your batter evenly among the muffin cups, filling each one about 3/4 full to give them room to rise without overflowing.
7. Bake Your Muffins.
Pop the muffin tin into the preheated oven and bake for 20-25 minutes or until a toothpick inserted into the center of a muffin comes out clean, and the tops are a lovely golden brown.
8. Cool Down.
Once baked, let the muffins cool in the pan for about 5-10 minutes before transferring them to a wire rack. This step helps to avoid soggy bottoms.
9. Prepare the Glaze.
While the muffins cool, whisk together the powdered sugar and lemon juice until smooth. Adjust the consistency by adding more lemon juice if needed. You want it to be pourable but not too runny!
10. Drizzle and Enjoy!
Once your muffins have completely cooled, drizzle the glaze over the top. Let the glaze set for a minute, and then dive in! Enjoy the delightful tangy, moist muffins filled with blueberry and poppy seed goodness.
These muffins are perfect for breakfast, a snack, or even dessert. Enjoy every flavorful bite!
Can I Use a Different Type of Flour?
Yes! You can substitute all-purpose flour with whole wheat flour for a nuttier flavor and added nutrition. Keep in mind that whole wheat flour may result in a denser muffin, so you may need to adjust the liquid slightly.
How Do I Store These Muffins?
Store the muffins in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze them. Wrap each muffin tightly in plastic wrap and place them in a freezer-safe bag. They will keep for up to 3 months!
Can I Omit the Poppy Seeds?
Absolutely! If you prefer, you can leave out the poppy seeds for a smoother texture. Alternatively, you can replace them with chia seeds for a similar crunch and a bit of extra fiber!
What Can I Use Instead of Sourdough Starter?
If you don’t have sourdough starter, you can use plain yogurt or buttermilk as a substitute. This will maintain moisture in the muffins, but keep in mind you’ll miss the distinct sourdough flavor that adds depth to the muffins.
