Kitchen Tools You’ll Need
- Muffin tin
- Paper liners
- Large mixing bowl

Ingredients
- 120 g active sourdough starter (for flavor and rise)
- 90 g unsalted butter, melted and cooled (adds moisture and richness)
- 150 g granulated sugar (sweetness)
- 2 large eggs (binding agent and moisture)
- 120 ml milk (moisture)
- 1 tsp vanilla extract (enhances flavor)
- 1 tbsp lemon zest (brightness)
- 240 g all-purpose flour (structure)
- 1.5 tsp baking powder (leavening agent)
- 0.5 tsp baking soda (leavening agent)

- 60 g powdered sugar (optional glaze for sweetness)
- 1 tbsp fresh lemon juice (optional glaze for brightness)

How to Make Sourdough Blueberry Lemon Muffins
Step 1. Preheat your oven to 375°F (190°C) and prepare your muffin tin by lining it with paper liners. This step is crucial as it ensures that the muffins do not stick to the pan, making it easier for you to enjoy every last crumb.
Step 2. In a large mixing bowl, whisk together the sourdough starter, melted butter, granulated sugar, eggs, milk, and vanilla extract until everything is smooth and well combined. This mixture is the foundation of your muffins, and a smooth consistency helps incorporate the ingredients evenly.
Step 3. Add the lemon zest to the wet mixture and stir until it’s evenly distributed. The zest will infuse a lovely citrus aroma, enhancing the flavor of your muffins while providing a fresh note that complements the blueberries.
Step 4. In another bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This step ensures that the leavening agents are mixed evenly throughout the dry ingredients, which is key for achieving nice, fluffy muffins.
Step 5. Gently fold the dry mixture into the wet ingredients until just combined. Be mindful not to overmix, as this can lead to tough muffins. The batter should be slightly lumpy, which indicates that you’re on the right track.
Step 6. Toss the fresh blueberries in a little bit of flour before gently folding them into the batter. This light coating helps prevent the blueberries from sinking to the bottom during baking, ensuring they are evenly distributed throughout each muffin.
Step 7. Divide the batter evenly among the muffin cups, filling each about three-quarters full. This allows room for the muffins to rise without overflowing, creating that lovely dome shape as they bake.
Step 8. Bake your muffins in the preheated oven for about 20 to 25 minutes, or until they are golden brown and a toothpick inserted comes out clean. Keep an eye on them toward the end of baking; they’ll look puffy and golden when they’re ready.
Step 9. Allow the muffins to cool briefly in the pan before transferring them to a wire rack. This step helps them firm up a bit while still being warm and tender.
Step 10. If you’re opting for the lemon glaze, mix the powdered sugar and lemon juice until smooth, then drizzle it over the muffins once they’ve cooled slightly. The glaze adds a lovely sweetness and a touch of brightness to finish off the muffins.

Serving Suggestions
These muffins are delightful for breakfast, making an excellent start to your day when paired with a cup of coffee or tea. They also serve as a convenient snack throughout the day or a sweet treat after family meals. The muffins stay well, so you can enjoy them over a few days. If you’re lucky enough to have any leftovers, they can be a charming addition to lunchboxes or picnics.
Pro Tips for Best Results
- Use room-temperature ingredients: This helps achieve a better texture in your muffins.
- Toss blueberries in flour: This prevents them from sinking to the bottom.
- Avoid overmixing: This keeps the muffins light and tender.
- Check for doneness early: Ovens vary, so start checking at 20 minutes to avoid overbaking.
- Let muffins cool before glazing: This prevents the glaze from melting into the muffins.
- Store properly: Ensuring they are stored in an airtight container keeps them fresh longer.
Common Mistakes to Avoid
- Not using room-temperature ingredients: Cold ingredients can lead to uneven mixing and dense muffins. Aim for ingredients that are at a similar temperature to promote a smooth batter.
- Overmixing the batter: This results in tough muffins rather than light, fluffy ones. Mix only until ingredients are combined to maintain tenderness.
- Skipping the flour coating for blueberries: This can cause the berries to sink during baking. Toss them in a small amount of flour before folding them into the batter.
- Baking at the wrong temperature: Ensure your oven is preheated accurately. If the temperature is too high, the muffins may brown too quickly without cooking through.
- Not monitoring baking time: All ovens vary, so set a timer for 20 minutes and check for doneness. Adjust as needed to avoid overbaking.
- Glazing too early: If you drizzle the glaze on while the muffins are still too warm, it may soak in or run off. Wait for them to cool slightly for the best presentation.
Variations & Substitutions
You might consider adding chopped nuts or swapping blueberries for another berry like raspberries or strawberries if desired. A sprinkle of cinnamon or nutmeg can also enhance the spice notes. If you’re in the mood for a different zest, orange zest could provide a pleasant twist as well.
Storage & Reheating
Store muffins at room temperature in an airtight container for up to three days. For longer storage, keep them in the refrigerator for about a week or freeze them for up to three months. When you’re ready to enjoy them, reheat in a microwave for about 10-15 seconds or in an oven at 350°F until warmed through, which helps to maintain their soft texture.
