You Will Need
Before we dive into the baking process, let’s gather our ingredients:
Dry Ingredients:
- All-Purpose Flour (2 cups): Serves as the primary structure for the muffins, giving them their form and texture.
- Alternative: Whole wheat flour can be used for a denser, more wholesome muffin, though it may slightly alter the taste and texture.
- Granulated Sugar (1 cup): Sweetens the muffins and aids in browning.
- Alternatives: Coconut sugar or honey can be substituted for a different flavor profile; however, using liquid sweeteners like honey may require adjusting the dry ingredients to maintain batter consistency.
- Poppy Seeds (1 tablespoon): Introduce a subtle nutty flavor and a pleasant crunch.
- Alternative: Chia seeds can be used for a similar texture, though they may slightly alter the flavor.
- Baking Powder (2 teaspoons): Acts as a leavening agent, helping the muffins rise and become fluffy.
- Alternative: If unavailable, an additional 1/2 teaspoon of baking soda combined with an acidic ingredient like buttermilk can be used, but this may affect the overall flavor.
- Baking Soda (½ teaspoon): Works alongside baking powder to aid in leavening, especially in the presence of acidic components like lemon juice and sourdough discard.
- Alternative: If substituting, adjust with baking powder as mentioned above.
- Salt (½ teaspoon): Enhances and balances the flavors of the muffins.
- Alternative: Sea salt or kosher salt can be used in equal amounts.
Wet Ingredients:
- Sourdough Discard (1 cup): Adds moisture, a subtle tangy flavor, and helps reduce waste from sourdough starter maintenance.
- Alternative: If sourdough discard is unavailable, plain yogurt or buttermilk can be used to provide moisture and a slight tang.
- Milk (1 cup): Contributes to the batter’s moisture and helps dissolve dry ingredients.
- Alternatives: Non-dairy milks like almond, soy, or oat milk can be used for a dairy-free version.
- Unsalted Butter, melted (½ cup): Provides richness and moisture to the muffins.
- Alternatives: Coconut oil or vegetable oil can be substituted in equal amounts for a dairy-free option.
- Large Eggs (2): Act as binding agents, providing structure and stability to the muffins.
- Alternative: For an egg-free version, flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg) can be used, though the texture may be slightly denser.
- Fresh Lemon Juice (1 tablespoon): Imparts a bright, citrusy flavor and reacts with baking soda to aid in leavening.
- Alternative: Bottled lemon juice can be used in a pinch, but fresh juice offers a more vibrant flavor.
- Vanilla Extract (1 teaspoon): Enhances the overall flavor profile, adding a sweet, aromatic note.
- Alternative: Almond extract can be used for a different, nutty flavor, but should be used sparingly due to its potency.
Optional Lemon Glaze:
- Powdered Sugar (1 cup): Sweetens the glaze, providing a smooth, glossy finish.
- Alternative: A homemade version can be made by blending granulated sugar until fine, though the texture may be slightly different.
- Fresh Lemon Juice (2 tablespoons): Adds a tangy, citrusy flavor to the glaze, complementing the muffin’s lemon notes.
- Alternative: As with the batter, bottled lemon juice can be used if fresh lemons are unavailable.

Step-By-Step Guide
- Preheat the Oven: Begin by preheating your oven to 350°F (175°C). This ensures the oven reaches the desired temperature by the time your batter is ready, promoting even baking. Next, line a 12-cup muffin tin with paper liners. Using liners not only makes for easy cleanup but also helps in retaining the moisture of the muffins.
- Pro Tip: If you don’t have paper liners, lightly grease each muffin cup with butter or a non-stick spray to prevent sticking.
- Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, poppy seeds, baking powder, baking soda, and salt.Whisking ensures that all dry ingredients are evenly distributed, which is crucial for the muffins to rise properly and have a consistent flavor.
- Pro Tip: For an extra burst of lemon flavor, consider adding the zest of one lemon to the dry mixture.
- Combine Wet Ingredients: In another bowl, mix the sourdough discard, milk, melted butter, eggs, lemon juice, and vanilla extract until well combined. Ensure the melted butter isn’t too hot, as it might cook the eggs. Combining these ingredients well ensures a uniform batter.
- Pro Tip: Using room temperature eggs helps in achieving a smoother batter and better incorporation with the other ingredients.
- Combine Wet and Dry: Pour the wet ingredients into the bowl containing the dry ingredients. Using a spatula or wooden spoon, gently fold the mixtures together until just combined. It’s normal for the batter to be slightly lumpy; overmixing can lead to dense muffins.
- Pro Tip: To prevent overmixing, stir until you no longer see dry flour pockets. A few small lumps are acceptable.
- Fill Muffin Tin: Evenly distribute the batter among the 12 muffin cups. Filling each cup about two-thirds full ensures room for the muffins to rise without overflowing.
- Pro Tip: For uniform muffin sizes, use an ice cream scoop to transfer the batter into the muffin cups.
- Bake: Place the muffin tin in the preheated oven. Bake for approximately 20 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with just a few moist crumbs. The tops should be lightly golden.
- Pro Tip: Oven temperatures can vary. It’s advisable to check the muffins a minute or two before the suggested baking time to prevent overbaking.
- Prepare Glaze (Optional): While the muffins are baking, you can prepare a simple lemon glaze for added flavor:
- In a small bowl, mix together 1 cup powdered sugar and 2 tablespoons fresh lemon juice until smooth.
- Pro Tip: For a thicker glaze, add more powdered sugar; for a thinner consistency, incorporate a bit more lemon juice.
- Glaze the Muffins: Once the muffins are done baking, remove them from the oven and allow them to cool in the tin for about 5 minutes. Then, transfer them to a wire rack to cool slightly. If you’re using the lemon glaze, drizzle it over the warm muffins, allowing it to seep in and add moisture.
- Pro Tip: Placing a sheet of parchment paper under the wire rack can catch any excess glaze, making cleanup easier.
- Serve and Enjoy: These muffins are best enjoyed warm, showcasing their moist texture and vibrant lemon flavor. Pair them with a cup of tea or coffee for a delightful treat.
Tips for Perfect Muffins
- Avoid Overmixing: Mix the batter just until combined. Overmixing can lead to dense muffins.
- Use Room Temperature Ingredients: Allow your eggs, milk, and melted butter to come to room temperature for a smoother batter.
- Customize Your Muffins: Feel free to add a handful of blueberries or a sprinkle of chopped nuts for added flavor and texture.

How to Store Your Muffins
To keep your Sourdough Lemon Poppy Seed Muffins fresh and delicious, follow these storage tips:
- At Room Temperature: Once the muffins have cooled completely, place them in an airtight container. They can be stored at room temperature for up to 3 days.
- In the Refrigerator: If you’d like to keep them longer, store the muffins in an airtight container in the refrigerator for up to 1 week.
- Freezing: For extended storage, wrap each muffin individually in plastic wrap or aluminum foil, then place them in a freezer-safe bag or container. They can be frozen for up to 3 months. To enjoy, thaw at room temperature or warm them briefly in the microwave.
How to Decorate the Muffins
While these muffins are delightful on their own, adding a decorative touch can make them even more appealing:
- Lemon Glaze: Drizzle the optional lemon glaze over the cooled muffins for a sweet and tangy finish.
- Candied Lemon Peel: Top each muffin with a small piece of candied lemon peel to enhance the citrus flavor and add visual appeal.
- Poppy Seeds: After glazing, sprinkle a few extra poppy seeds on top for added crunch and decoration.
- Edible Flowers: For a touch of elegance, adorn each muffin with an edible flower that complements the lemon flavor.
