Irresistible Sourdough Lemon Poppyseed Muffins (Bright & Zesty!)
The first time I experimented with sourdough in muffins, I wasn’t sure what to expect. Would they be too tangy? Too dense? But as the scent of fresh lemon and warm butter filled the kitchen, I knew I had something special.
These sourdough lemon poppyseed muffins have since become my family’s favorite morning treat—a perfect balance of citrusy brightness, subtle sourdough tang, and nutty crunch.

Using sourdough starter not only reduces waste but also creates incredibly moist muffins with a depth of flavor you won’t find in a traditional lemon poppy seed muffin. Let’s bake up a batch of these irresistible treats!
Why You’ll Love This Recipe
- Bright citrus flavor: Fresh lemon zest and juice provide the perfect tangy balance.
- Light and fluffy texture: Sourdough starter keeps these muffins soft and tender.
- Nutty crunch: Poppy seeds enhance both texture and flavor.
- Easy to make: No long fermentation time—just mix and bake!
- Great way to use extra sourdough starter: No discard goes to waste.
Ingredients & Substitutions
- 1 cup sourdough starter (active or discard)
- ½ cup granulated sugar (or coconut sugar for a deeper flavor)
- ½ cup unsalted butter, melted (or coconut oil for dairy-free option)
- 2 large eggs
- ½ cup milk (regular or non-dairy like almond or oat milk)
- 2 tbsp fresh lemon zest (for stronger citrus aroma)
- 2 tbsp fresh lemon juice (for bright lemon flavor)
- ½ tsp lemon extract (optional, but recommended)
- 1 ½ cups all-purpose flour (or a whole wheat blend)
- 2 ½ tsp baking powder (ensures a better rise!)
- ½ tsp baking soda (reacts with lemon juice for fluffier texture!)

Step-by-Step Instructions
- Preheat oven to 375°F (190°C). Line a muffin tin with paper liners.
- Mix wet ingredients: In a large bowl, whisk together sourdough starter, sugar, melted butter, eggs, milk, lemon zest, lemon juice, and lemon extract until smooth. (If using yogurt/sour cream, add it now.)
- Prepare dry ingredients: In another bowl, whisk together flour, baking powder, baking soda, salt, and poppy seeds.
- Combine gently: Gradually fold dry ingredients into wet ingredients until just combined. (Do not overmix! Overmixing = dense muffins.)
- Fill muffin tin: Scoop batter into muffin liners, filling each about ¾ full.
- Bake: Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
- Cool and glaze (optional): Let muffins cool for 5 minutes in the pan, then transfer to a wire rack. If using glaze, drizzle over cooled muffins.

Expert Tips for Perfect Muffins
- Use room-temperature ingredients: This helps the batter mix evenly for tender muffins.
- Mix until just combined: Overmixing can lead to dense muffins.
- Fresh lemons are key: Bottled lemon juice won’t achieve the same brightness.
- Want extra lemon flavor? Top with a simple lemon glaze made from powdered sugar and fresh lemon juice.
- Storage: Keep in an airtight container at room temperature for up to 4 days or freeze for up to 3 months.
