Step‑by‑Step Instructions for Lemon Blueberry Sourdough Cookies
Step 1: Prep Ingredients
Start by gathering all ingredients, ensuring the butter and egg are at room temperature for optimal mixing. Measure out your sourdough starter, lemon juice, and zest. This is a crucial step to achieve the best texture and flavor in your Lemon Blueberry Sourdough Cookies, so take your time to prepare.
Step 2: Preheat Oven
Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper. This ensures an easy release of the cookies without sticking and helps achieve that lovely golden edge. Take a moment to visualize the warm, inviting aroma that will soon fill your kitchen.
Step 3: Cream Butter and Sugars
In a mixing bowl, combine the softened butter with cane and brown sugars. Using a mixer, beat until the blend is light and fluffy, which should take about 3-4 minutes. This step adds air into the mixture, creating a delightful texture for your Lemon Blueberry Sourdough Cookies.
Step 4: Add Wet Ingredients
Now, mix in the room-temperature egg, lemon extract, lemon juice, and your sourdough starter until everything is well blended and fluffy. This combination will enhance the cookies’ moisture and flavor, setting a zesty tone perfectly paired with the blueberries.
Step 5: Combine Dry Ingredients
In a separate bowl, sift together the flour, baking soda, baking powder, and salt. Sifting ensures these dry ingredients are well mixed and free of lumps, which is vital for uniform rising in your Lemon Blueberry Sourdough Cookies. Take care to enjoy the aroma of the fresh flour.
Step 6: Mix Dry into Wet
Gradually add the dry ingredient mix to the wet ingredients, folding gently until just combined. Be cautious to avoid overmixing, which can affect the final texture. A few flour streaks are okay, as they will disappear while baking, leaving you with perfect cookies.
Step 7: Fold in Blueberries and Preserves
Carefully fold in the washed and dried blueberries along with the blueberry preserves. This step beautifully swirls bursts of fruit flavor throughout the dough. Make sure to distribute the blueberries evenly, setting the stage for delectable bites in your Lemon Blueberry Sourdough Cookies.
Step 8: Chill Dough
Cover the dough with plastic wrap and refrigerate it overnight. This chilling period is crucial as it helps the flavors meld and firms up the dough, which prevents spreading during baking. Imagine waking up to the promise of fresh-baked cookies just waiting to be shaped.
Step 9: Shape Cookies
Once chilled, scoop the dough and roll it into balls, then coat each ball with cane sugar for added sweetness and a lovely finish. Arrange them on your lined baking sheet, spacing them a couple of inches apart to allow room for spreading while baking.
Step 10: Bake
Place your baking sheet in the preheated oven and bake for 15-18 minutes, or until the edges are lightly golden and the centers look soft. Avoid overbaking to preserve the chewy texture of your Lemon Blueberry Sourdough Cookies. The delightful scent will be your guide!
Step 11: Cooling
After baking, let the cookies cool completely on the baking sheet for about 10 minutes before transferring them to a cooling rack. This allows them to set up nicely, achieving that perfect blend of soft and chewy without falling apart. Enjoy the anticipation of savoring them!

Tips for the Best Lemon Blueberry Sourdough Cookies
- Use Room Temperature Ingredients: Ensure butter and egg are at room temperature; this promotes even mixing and results in a better texture for your cookies.
- Chill the Dough: Don’t skip the overnight chilling! This step develops flavors and prevents excessive spreading during baking.
- Check Butter Consistency: If the dough spreads too much, your butter may have been too soft. Aim for a softened but not melted consistency for the best results.
- Mix Gently: When combining dry and wet ingredients, fold gently to avoid overmixing. This will keep your Lemon Blueberry Sourdough Cookies soft and tender.
- Adjust Baking Time: Keep an eye on the cookies! Remove them from the oven when the edges are golden, but the centers should remain soft for a delicious chewy texture.

Lemon Blueberry Sourdough Cookies Recipe FAQs
What type of blueberries should I use?
I recommend fresh blueberries for their vibrant flavor and texture. If you’re using frozen blueberries, make sure to coat them lightly in flour before adding them to the dough to prevent excess moisture. This helps maintain the cookie’s delightful texture and prevents sogginess.
How should I store the cookies?
Store your Lemon Blueberry Sourdough Cookies in an airtight container at room temperature for up to 3 days. For longer freshness, you can refrigerate them for up to a week. Just ensure the container is sealed well to keep them from drying out.

When you’re ready to enjoy, simply thaw them at room temperature or reheat them in the oven or microwave for a few seconds.
Why did my cookies spread too much?
If your Lemon Blueberry Sourdough Cookies spread too much while baking, it may be due to the butter being too soft or not chilling the dough long enough. Ensure your butter is softened but not melted, and be sure to chill the dough overnight to allow it to firm up. If they still spread, try chilling the dough for an additional hour before baking.
