If you have a sourdough starter then you will probably also have an endless supply of sourdough discard. If makes a great addition to a variety of baked goods, such as these Sourdough Ham and Cheese Scones or this Sourdough Blueberry Scones.

Just like our Sourdough Apple Cinnamon Muffins, Sourdough Orange Creamsicle Muffins, Sourdough Raspberry Muffins, Sourdough Discard Chocolate Chip Muffins, Sourdough Discard Gingerbread Muffins, Sourdough Cranberry Cream Cheese Muffins, and Orange Cranberry Sourdough Muffins these muffins are a delicious breakfast option.

Recipe Ingredients

All you need are a few simple ingredients to make these Homemade Lemon Poppy Seed Sourdough Muffins.

Lemon Poppyseed Muffin ingredients on a white wood surface.

All-Purpose Flour: No special flours are needed for these cookies. All-purpose flour is perfect. For accuracy, the best way to measure the flour is by using a digital kitchen scale.

Tip: If you don't have a digital scale, spoon the flour into the measuring cup and level it with the back of a butter knife. Try not to compress the flour into the measuring cup.

Corn Starch: Adding cornstarch to muffins reduces gluten formation and gives them a lighter softer texture.

Salt: I add at least a pinch of salt to all of my recipes. Salt complements and intensifies the other flavors. For all of my recipes, I use Morton Kosher Salt which packs more densely than Diamond Crystal Kosher Salt. If you are using Diamond Crystal Kosher Salt you will want to double the amount of salt you add.

Poppy Seeds:

Lemons: When zesting a lemon, you only want to use the outer yellow layer, not the bitter white pith.

Sourdough Discard: Don't worry your muffins won't be sour. This is plenty of sugar to eliminate the sourdough flavor. Bring your sourdough discard to room temperature before adding it to the recipe. It will be easier to incorporate. Active starter or sourdough discard can be used for this recipe.

Pro Sourdough Tip: Keep a glass jar in your refrigerator to store your sourdough discard. Continue adding to it until you have enough to make your chosen sourdough discard recipe.

Oil: Because oil remains a liquid at room temperature it helps to create a moist muffin. Use either canola or vegetable oil.

Buttermilk: Buttermilk reacts with baking soda to help the muffins rise. If you do not have buttermilk you can use regular milk and stir in one tablespoon of vinegar or lemon juice. Allow the mixture to sit for a few minutes until it curdles.

See the recipe card for full information on ingredients and quantities.

Substitutions and Variations

Loaf Pans: Muffins and quickbreads are very similar and can often be baked in a loaf pan instead of a muffin pan.

  1. Pour the batter into the 2 greased 9x5 loaf pans and bake at 350°F for 60 to 65 minutes. The Orange Creamsicle bread is done when a toothpick inserted into the center of the loaf comes out clean.
  2. Remove from the oven and allow the bread to cool in the pan for 15 minutes. Remove the bread from the pan and cool completely on a wire rack.

Jumbo or Mini Muffins:

  • For mini muffins, bake at 350°F for 11-13 minutes. Yields about 48 mini muffins.
  • For jumbo-size muffins baked at 425°F for 5 minutes and then lower the temperature to 350°F for 25-30 minutes. Yields about 12 jumbo muffins.

Sourdough Discard: If you don't have sourdough discard, you can easily substitute the same amount of sour cream, yogurt, or unsweetened applesauce.

Buttermilk: Buttermilk reacts with baking soda to help the muffins rise. If you do not have buttermilk you can use regular milk and stir in one tablespoon of vinegar or lemon juice. Allow the mixture to sit for a few minutes until it curdles.

Step by Step Directions

Lemon poppyseed muffin dry ingredients in a white bowl.

Step 1: Move the oven rack to the middle position. Preheat the oven to 425°F (220°C). Grease two standard 12-count muffin pans with nonstick spray or line them with muffin papers. Set aside.

Step 2: In a large bowl, whisk together the all-purpose flour, cornstarch, poppy seeds, baking powder, baking soda, and kosher salt until well combined.

Step 3: In a separate bowl, add the granulated sugar and the zest from the lemons. Massage and pinch to zest into the sugar.

Tip: Massaging the zest into the sugar helps to release the orange oils.

Step 4: Add the lemon juice, sourdough discard, neutral oil, buttermilk, eggs, and vanilla to the bowl containing the sugar and lemon zest. Mix until smooth.

Step 5: Pour the wet ingredients into the dry ingredients and stir until just combined.

Tip: Do not overmix the batter. Overmixing can incorporate too much air causing the muffins to rise quickly and then fall in the center as they bake. Overmixing can also create tough muffins.

Step 6: Divide the muffin batter evenly among the muffin cups filling nearly to the top.

Step 7: Bake the muffins in the preheated oven for 5 minutes, then, keeping the muffins in the oven, reduce the oven temperature to 350°F (180°C) and continue to bake for 13 to 16 minutes until the tops are golden brown.

Allow the muffins to cool for several minutes in the muffin pan before transferring them to a wire rack to cool completely.

Tips: Use a cookie scoop to evenly portion the cupcake batter into the muffin pans.

Tip: Starting the muffins at a higher temperature will boost the rise giving you a taller muffin top.

Tip: Use a toothpick to test for doneness. Insert a toothpick into the center of a muffin, if it comes out clean, the muffins are done. For ways to check the muffin's doness read this post: How to Tell Banana Bread is Done.

Frequently Asked Questions

Do you need muffin liners for baking muffins?

Muffins can be baked with or without liners. If baked with liners they will have a softer outside texture. Muffins baked without liners will be slightly crispier and darker on the outside.
I couldn't find jumbo muffin liners at my local store, so I bought these muffin liners from Amazon.

What is the best temperature for baking muffins?

To get a tall muffin, start baking your muffins at a higher temperature then after about five minutes lower the temperature.

I start my muffins at 425°F and then lower the temperature to 350°F. Starting at a higher temperature gives the baking soda and baking powder a nice boost of heat that encourages leavening.

It also allows the outside of the muffin to set quickly giving the inside the structure it needs to keep rising.

How do you store muffins?

These muffins will stay moist for a couple of days when stored at room temperature. Leftover muffins can be stored in an airtight container for 2-3 days.

For longer storage, keep them in the refrigerator for up to a week.

They can also be frozen for up to 3 months. Wrap each muffin in plastic wrap and place them in a zip-top bag. Thaw muffins at room temperature.

Expert Tips

  • Muffins bake best on the middle rack of the oven. Too low and the bottoms will burn, too high and the tops will brown too quickly.
  • When zesting a lemon, you only want to use the outer yellow layer, not the bitter white pith.
  • Don't over-mix the batter. A few lumps are fine. Overmixing will create too much gluten causing your muffins to be tough.
  • Use a cookie scoop to evenly portion the cupcake batter into the muffin pans.
  • Use a toothpick to test for doneness. Insert a toothpick into the center of a muffin, if it comes out clean, the muffins are done. For ways to check the muffin's doness read this post: How to Tell Banana Bread is Done.
