This lemon blueberry cookie recipe captures the perfect balance of bright citrus and juicy berries in a soft, chewy cookie. The cookies bake up with golden edges and a tender center that melts in your mouth, creating a taste of spring you can enjoy any time of year.
I first developed these cookies when looking for something different to bring to a spring garden party. Three batches later, they've become my most requested dessert for gatherings of all kinds, with friends always asking for the "magic lemon cookies" recipe.
Ingredients
- All purpose flour: Provides the perfect structure for these soft cookies without being too dense
- Cornstarch: The secret ingredient that ensures these cookies stay tender and chewy
- Baking powder and baking soda: Work together to create the ideal rise and texture
- Fresh lemons: Zested directly into sugar infuses maximum flavor throughout the dough
- Melted butter: Creates a chewier cookie with a more complex flavor than creamed butter
- Fresh blueberries: Add juicy bursts of flavor and beautiful color throughout each cookie
- Sugar: For rolling creates a delicate crackly exterior that adds textural contrast
Step-by-Step Instructions
- Prepare the oven and butter:
- Preheat your oven to 375°F and line baking sheets with parchment paper. Melt the butter completely then place in refrigerator for 10 minutes. This cooling step is crucial as it prevents the butter from being too hot when mixed with other ingredients which would result in flat cookies.
- Make the lemon sugar:
- Whisk granulated sugar with fresh lemon zest until it resembles wet sand. This technique releases the essential oils from the zest and infuses the sugar with intense lemon flavor. The sugar will become slightly yellow and incredibly fragrant letting you know you've done it correctly.
- Mix the wet ingredients:
- Add cooled melted butter to the lemon sugar and whisk until completely combined and smooth. Then incorporate the egg, egg yolk, and vanilla extract whisking until the mixture becomes lighter in color and well blended. Each of these elements adds richness and structure to the final cookie.
- Combine dry ingredients:
- In a separate bowl whisk together flour, cornstarch, baking powder, baking soda, and salt. This ensures even distribution of the leavening agents through the flour for consistent cookie texture.
- Form the dough:
- Gently fold the dry ingredients into the wet mixture until just combined, careful not to overmix which would develop gluten and toughen the cookies. Fold in blueberries with minimal stirring to keep them whole and prevent color bleeding throughout the dough.
- Shape and bake:
- Scoop dough using a medium cookie scoop, roll in sugar if desired, and place on prepared baking sheets. Bake until edges are set and lightly golden while centers remain soft, about 10 to 12 minutes. The cookies will continue cooking from residual heat after removed from oven.

The lemon sugar technique is truly the heart of this recipe. I discovered it while making Italian limoncello years ago when I noticed how rubbing lemon zest into sugar released an incredible aroma. Now I use this technique in all my lemon baked goods because it distributes the citrus flavor so evenly throughout the entire cookie not just in occasional bites.
Working With Blueberries
Fresh blueberries work beautifully in this recipe but require gentle folding to prevent crushing. Look for firm berries with a dusty blue color as these will hold their shape best during baking. If using frozen blueberries smaller wild varieties distribute best throughout the dough and minimize color bleeding. Never thaw frozen berries before adding them to your dough as they'll become mushy and turn your cookies blue.
Storage Tips
These cookies maintain their perfect texture when stored in an airtight container at room temperature for up to 3 days. For longer storage refrigerate for up to 5 days though the cookies will firm up slightly when chilled. Bring refrigerated cookies to room temperature before serving to restore their chewy texture. You can also freeze the baked cookies in a single layer then transfer to a freezer bag for up to 3 months.
Flavor Variations
Try adding white chocolate chips for extra sweetness and creaminess that pairs beautifully with the tart lemon and blueberries. For an extra lemon punch add a simple glaze made with powdered sugar and fresh lemon juice. These cookies also work wonderfully with other berries like raspberries or blackberries or even dried cranberries for a different twist on the flavor profile.
Serving Suggestions
These cookies make a lovely accompaniment to afternoon tea or coffee. For an elegant dessert sandwich two cookies with lemon curd or vanilla ice cream. They also package beautifully for gift giving especially in spring and summer. I love serving them slightly warm so the blueberries are still a bit jammy inside creating the perfect contrast to the chewy cookie.
