Soft Lemon Blueberry Cookies

This lemon blueberry cookie recipe brings the perfect balance of bright citrus and sweet berries into a soft, chewy cookie that reminds me of sunshine even on the cloudiest days. The combination creates an irresistible treat that works year-round but feels especially perfect when spring flowers start blooming.

I first created these cookies when looking for something special but simple to bring to a spring garden party. They were such a hit that they've become my signature dessert for everything from baby showers to book clubs.

Ingredients

• All purpose flour: Provides the perfect structure without being too heavy
• Cornstarch: Creates that melt-in-your-mouth tender texture you crave in cookies
• Baking powder and baking soda: Work together for the ideal rise and texture
• Salt: Enhances all the flavors and balances the sweetness
• Granulated sugar: Sweetens while helping create those slightly crisp edges
• Fresh lemon zest: Contains aromatic oils that provide intense flavor
• Melted butter: Creates a chewier texture than creamed butter does
• Egg and egg yolk: Add richness and help bind everything together
• Vanilla extract: Provides depth and enhances the berry flavor
• Fresh blueberries: Burst with juicy sweetness; look for plump, firm berries
• Extra sugar for rolling: Adds a beautiful sparkle and slight crunch

Step-by-Step Instructions

Prepare the Oven:

Preheat your oven to 375°F and give it at least 20 minutes to come to temperature. This ensures your cookies bake evenly from the first batch to the last. Line baking sheets with parchment paper which prevents sticking and makes cleanup easier.

Prepare the Butter:

Melt the butter completely then cool it in the refrigerator for about 10 minutes. This cooling step is crucial as it prevents the butter from cooking the eggs when combined and helps maintain the right cookie texture.

Mix Dry Ingredients:

Whisk together flour, cornstarch, baking powder, baking soda, and salt until thoroughly combined. This even distribution ensures consistent flavor and texture throughout every cookie.

Create Lemon Sugar Base:

In a large bowl, combine sugar and fresh lemon zest, whisking until it resembles wet sand. This technique releases the essential oils from the zest, infusing the sugar with intense lemon flavor that will permeate the entire cookie.

Combine Wet Ingredients:

Add the cooled melted butter to the lemon sugar and whisk until completely incorporated. Then add the egg, egg yolk, and vanilla, whisking until the mixture is smooth and uniform. The egg yolk adds richness while the whole egg provides structure.

Form Cookie Dough:

Gently fold the dry ingredients into the wet mixture just until combined, being careful not to overmix which would develop too much gluten and toughen the cookies. Carefully fold in the blueberries with minimal stirring to prevent breaking them and turning the dough purple.

Shape and Prepare for Baking:

Use a medium cookie scoop to portion the dough into equal balls. If desired, roll each ball in granulated sugar for extra sweetness and a beautiful sparkly appearance. Place them on the prepared baking sheet with plenty of space between each cookie to allow for spreading.

Bake to Perfection:

Bake at 375°F for 10 to 12 minutes or until the edges are set and lightly golden. The centers may look slightly underdone which is perfect for achieving that soft, chewy texture once cooled.

Cool Properly:

Allow cookies to rest on the baking sheet for 3 to 4 minutes which lets them set up enough to be moved without breaking. Then transfer to a wire rack to cool completely, allowing air to circulate and preventing soggy bottoms.

Pin it

My absolute favorite part of these cookies is watching people take their first bite. The surprise of getting both lemon and blueberry flavors in a cookie always brings smiles. My daughter now requests these for her lunchbox treats during spring when she needs a little brightness in her day.

Storing Your Cookies

These lemon blueberry cookies stay wonderfully soft and fresh for up to five days when stored in an airtight container. I find that placing a small piece of bread in the container helps maintain moisture and keeps them at their perfect chewy texture. During warmer months, refrigerating them is best to prevent the blueberries from becoming too soft. They also freeze beautifully for up to three months wrapped individually in plastic wrap then placed in a freezer bag.

Working with Frozen Blueberries

When fresh berries aren't in season, frozen wild blueberries make an excellent substitute in this recipe. Their smaller size distributes more evenly throughout the cookie dough. The key to success with frozen berries is using them straight from the freezer without thawing and handling the dough minimally to prevent color bleeding. Remember to reduce your oven temperature to 350°F and extend baking time to 14 to 16 minutes for perfect results with frozen berries.

Flavor Variations

This versatile base recipe welcomes creative adaptations. Try replacing blueberries with raspberries for a different berry profile or add white chocolate chips for extra sweetness and visual appeal. For an extra lemon punch, consider adding a simple glaze made from powdered sugar and fresh lemon juice drizzled over the cooled cookies. During winter holidays, adding a teaspoon of dried cranberries along with the blueberries creates a festive red and blue color combination that looks beautiful on cookie platters.

Frequently Asked Questions

→ Can I use frozen blueberries for these cookies?

Yes, you can use frozen blueberries. Opt for wild blueberries, which are smaller and suit this recipe better. Mix them in just before scooping the dough and reduce the baking temperature slightly to 350°F (177°C).

→ Do I need to chill the dough?

No, this recipe is designed to be no-chill, so you can bake the cookies immediately after preparing the dough.

→ How do I store the baked cookies?

Place the baked cookies in an airtight container. Store them at room temperature or in the fridge for up to 5 days.

→ What’s the best way to zest the lemons?

Use a fine zester to scrape the outermost yellow layer of the lemon peel, avoiding the bitter white pith underneath.

→ Can I substitute regular sugar for the rolling step?

Yes, you can skip the sugar rolling step or substitute it with coarse sugar for added texture.
