Ingredients You’ll Need
- sourdough discard (unfed starter) (but fed works good too)
- baking powder
- salt
- all-purpose flour
- avocado oil (or melted butter)
- a large egg
- cane sugar
- pure vanilla extract
- milk
- lemon juice (about 1 1/2 lemons)
- lemon zest (about 2 lemon)
- poppyseeds
Kitchen Tools You’ll Need
- microplane/zester
- mixing bowl
- whisk
- measuring cups/spoons (I love these ones!)

Molly’s Muffin Tips
- Zest with Ease: To make zesting lemons easy, use a microplane zester. It makes it so easy and they’re inexpensive. I just got one myself and love it!
- Use Avocado Oil: Avocado oil in muffins is the best! It creates the perfect fluffy texture without adding any flavors.
- Organic is Best: Organic lemons are the best for these muffins. They have a better taste and the peels aren’t sprayed with chemicals. I get mine at Walmart or Kroger. But you can use regular too.
- Don’t Overmix: Avoid over mixing your batter to ensure fluffy muffins. Over mixing will make your them dense.

How to Make Sourdough Lemon Poppyseed Muffins
Preheat the oven to 375 degrees Fahrenheit. (If you’re long fermenting the batter wait to do this)
In a large mixing bowl, add all ingredients. Whisk until everything is combined. Avoid over-mixing the batter.
Optional – At this point you can either continue the recipe or place the batter covered in the fridge for 12-24 hours to long ferment for more sourdough gut benefits.
To continue the recipe, grease a muffin tin with butter and a dusting of flour to prevent sticking or line the tin with paper muffin liners.

Fill each liner 3/4 of the way full.


Bake at 375 degrees Fahrenheit for 22-25 minutes or until a toothpick comes out clean.

Take out of the oven and place pan on a cooling rack. Let cool for 5 minutes before removing from the tin. Enjoy when ready!
How to Store Muffins
Store these muffins in an airtight container for 3-4 days at room temperature. You can also store them in the fridge for 5-6 days. Or freeze them up to 3 months.

Frequently Asked Questions
Yes, sourdough discard is a good option for these muffins since they don’t need to bulk ferment and rise like bread.
Yes you can! I recommend adding another 1/3 or 1/2 cup of sugar if desired.
Your muffins could be dense if you over mixed your batter. It can also happen if your baking powder is old and inactive (usually if it’s over a year old).
