Ingredients
Instructions
1. Prepare your muffin tin and preheat the oven: Start by preheating your oven to 400 F (200 C). Line a 12-cup muffin tin with paper liners or grease it thoroughly with butter or non-stick spray. This ensures your muffins won’t stick and makes for easy cleanup.
2. Combine the dry ingredients: In a large mixing bowl, whisk together the all-purpose flour, 1/2 cup granulated sugar, baking powder, baking soda, and salt. Make sure there are no lumps and all ingredients are evenly distributed. This step is crucial for even rising.
3. Mix the wet ingredients: In a separate medium bowl, whisk together the sourdough discard, milk, melted and cooled butter, egg, vanilla extract, and lemon zest until well combined. The mixture should be smooth and uniform.
4. Gently combine wet and dry mixtures: Pour the wet ingredients into the dry ingredients. Stir with a spatula or wooden spoon just until barely combined. The batter will be thick and lumpy, and that’s exactly what you want! Overmixing leads to tough muffins, so stop as soon as you no longer see streaks of dry flour.
5. Fold in the blueberries: Carefully add the fresh or frozen blueberries to the batter. Gently fold them in with your spatula, distributing them evenly without crushing them. If using frozen blueberries, do not thaw them first.
6. Fill the muffin cups: Divide the batter evenly among the 12 prepared muffin cups. Each cup should be about two-thirds full.
7. Add a sugary topping: Sprinkle the remaining 1 tablespoon of granulated sugar over the tops of the filled muffin cups. This creates a lovely, slightly crisp crust.
8. Bake until golden: Bake for 20-25 minutes, or until the muffins are golden brown and a wooden skewer or toothpick inserted into the center of a muffin comes out clean.
9. Cool before serving: Remove the muffin tin from the oven and let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely. This prevents them from becoming soggy on the bottom.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients beforehand makes the baking process smooth and enjoyable. Most of these items are likely already in your pantry, making this a convenient recipe to whip up on short notice.
INGREDIENTS:

- 1 ½ cups all-purpose flour
- ½ cup granulated sugar, plus 1 tablespoon for topping
- 2 teaspoons baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- 1 cup sourdough discard (unfed, 100% hydration)
- ½ cup milk (any kind)
- ¼ cup unsalted butter, melted and cooled
- 1 large egg
- 1 teaspoon vanilla extract
- Zest of 1 large lemon
- 1 cup fresh or frozen blueberries
For the flour, all-purpose is ideal for its balanced protein content, which yields a tender muffin crumb. If you prefer, you can use a 1:1 gluten-free flour blend, though the texture might vary slightly. Granulated sugar provides the perfect amount of sweetness, but you could experiment with a touch of brown sugar for a deeper molasses note. Any type of milk works well here; whole milk will give a richer muffin, while skim or plant-based milk will also do the trick. Unsalted butter is recommended so you can control the salt content, but if you only have salted butter, simply omit the ¼ teaspoon of added salt. Fresh lemon zest is key for that bright, zesty flavor, so don’t skip it! If fresh blueberries aren’t available, frozen ones work perfectly; just don’t thaw them before adding to the batter to prevent bleeding.
Time Needed From Start To Finish
This recipe is designed for efficiency, ensuring you can enjoy homemade muffins without spending hours in the kitchen.
- Preparation time: 15 minutes
- Baking time: 20-25 minutes
- Total time: 35-40 minutes
The hands-on time is minimal, primarily involving mixing the wet and dry ingredients separately before combining them. The baking time is standard for muffins, allowing them to rise beautifully and achieve a golden-brown finish.

Follow these straightforward steps to create perfect lemon blueberry sourdough discard muffins every time.

- Gently combine wet and dry mixtures: Pour the wet ingredients into the dry ingredients. Stir with a spatula or wooden spoon just until *barely* combined. The batter will be thick and lumpy, and that’s exactly what you want! Overmixing leads to tough muffins, so stop as soon as you no longer see streaks of dry flour.
- Fold in the blueberries: Carefully add the fresh or frozen blueberries to the batter. Gently fold them in with your spatula, distributing them evenly without crushing them. If using frozen blueberries, do not thaw them first.

Easy Variations And Serving Ideas That Fit Real Life
These lemon blueberry sourdough discard muffins are delicious as is, but there are many ways to adapt them to your family’s preferences or for different occasions.
For a more indulgent treat, consider adding a simple lemon glaze. Whisk together ½ cup powdered sugar with 1-2 tablespoons of fresh lemon juice until smooth, then drizzle over cooled muffins. If you’re not a fan of blueberries, swap them out for other berries like raspberries or chopped strawberries. A mix of berries also works wonderfully. For a touch of spice, a pinch of cinnamon or nutmeg can be added to the dry ingredients. To make them extra kid-friendly, you can reduce the lemon zest slightly and add a handful of white chocolate chips along with the blueberries. These muffins are fantastic served warm for breakfast or brunch, alongside scrambled eggs and bacon, or as a simple afternoon snack with a glass of milk. They also make a lovely addition to a potluck or picnic spread.
Common Slip-Ups And How To Avoid Them
Even simple recipes can have pitfalls. Being aware of these common mistakes will help you achieve perfect muffins every time.
One of the most frequent errors is overmixing the batter. When you combine the wet and dry ingredients, stir just until the flour streaks disappear. A lumpy batter is a happy batter! Overmixing develops the gluten in the flour too much, leading to tough, chewy muffins instead of light and tender ones. Another mistake is overfilling the muffin cups. Filling them more than two-thirds full can cause the muffins to overflow the tin, creating a messy bake and potentially unevenly cooked muffins. Ensure you divide the batter evenly. Not preheating your oven properly can also affect the rise and texture. A hot oven helps the muffins rise quickly and form a beautiful dome. Lastly, using cold ingredients straight from the fridge can impact the texture. While not as critical as in some other baking, allowing ingredients like milk and eggs to come to room temperature can help them incorporate more smoothly into the batter.
How To Store It And Make It Ahead Without Ruining Texture
Proper storage is key to keeping your muffins fresh and delicious, and they can also be made ahead for convenience.
Once completely cooled, store the muffins in an airtight container at room temperature for up to 3 days. To prevent them from becoming soggy, you can place a paper towel at the bottom of the container to absorb any excess moisture. If you need to store them longer, these muffins freeze beautifully. Place fully cooled muffins in a single layer in a freezer-safe bag or container, separating layers with parchment paper if stacking. They will keep well in the freezer for up to 3 months. To enjoy, simply thaw them at room temperature or warm them gently in the microwave for 20-30 seconds, or in a preheated oven at 300°F (150°C) for about 5-10 minutes until heated through. For making ahead, you can prepare the dry ingredients and wet ingredients (excluding the discard, which should be added just before mixing) separately the night before, then combine and bake in the morning for fresh muffins.
