The combination of sour cream and sourdough discard in these lemon poppy seed muffins adds moisture and creates a rich, soft crumb. Plus, it adds a subtle depth of flavor.

Ingredients for the lemon poppy seed sourdough muffins

- Sourdough discard- You can use sourdough discard or active sourdough starter in this recipe. Room temperature will be easier to incorporate but you can use cold discard too.
- Lemon zest & juice – The muffins have zest and juice to really pump up the lemon flavor. You will also need lemon juice to create the lemon glaze on top of the muffins. 2 large lemons should be sufficient.
- Sour cream – Like in my sourdough blueberry muffins, the sour cream adds moisture and flavor to the muffins.
- Olive oil or vegetable oil – I use olive oil in this recipe but you can use vegetable or canola oil as well.

Instructions to make Sourdough Lemon Poppy Seed Muffins

Step 1: To a large mixing bowl, add the sugar and lemon zest. Rub the mixture together in between your fingers to help release the oils from the zest.

Step 2: Add in the wet ingredients. Whisk in the oil, lemon juice, milk, sour cream, sourdough discard, vanilla extract, and eggs until combined.

Step 3: Add the flour, baking powder, poppy seeds, and salt to the wet ingredients and whisk until just combined. Do not over-mix.

Step 4: Scoop the batter into a muffin pan, dividing evenly between 12 paper liners or a greased pan.

Step 5: Bake in a preheated 400°F oven for 18-20 minutes until a toothpick comes out clean.

Step 6: In a small bowl, slowly whisk in lemon juice to the powdered sugar until you reach your desired consistency. Drizzle over the warm muffins.
Remove the muffins from the pan and let them cool on a wire cooling rack.
Recipe Tips
- Do not over-mix the muffin batter. If you mix it too much, gluten will start to develop which will create a tough and chewy muffin. Just mix the batter until it is combined and then stop.
- Check to see if the muffins are cooked through by inserting a toothpick into the center. You will know if the muffins are fully cooked if the toothpick comes out clean. All ovens are slightly different so it is best to check this way because cooking times can slightly vary.
- Pull the muffins out of the pan very soon after getting them out of the oven. When they sit in the hot pan, they begin to steam, which makes the muffin tough.

How to store the Sourdough Lemon Poppy Seed Muffins
The muffins can be stored at room temperature in an airtight container for 5 days. They can also be frozen, just wrap them in plastic wrap or store them in a freezer bag for up to 3 months. When you are ready to eat, you can let them thaw on the counter or add them to the microwave for a few seconds at a time until warm.
Recipe FAQ
Yes! A long fermentation helps break down the phytic acid in the flour, which makes the nutrients easier for your body to digest. If you would like to ferment the muffin batter, mix the batter together and before adding it to the muffin tin, add to the fridge for 12-24 hours. When you are ready to bake, add the batter to the muffin tin and follow the baking instructions.
Yes, you can substitute Greek yogurt if you prefer.
Yes, either active starter or discard will work in this recipe.
If you would rather make a loaf instead of muffins, you can add the batter to a greased 9×5-inch loaf pan and bake at 350°F for 60-70 minutes.

I have baked this twice as a loaf and it came out PERFECT. The second time I chopped an apple in small pieces and added that to the mix. Then added some apple slices on top and baked. It was really great!!!!
Yum! So glad you liked them.
