Balanced lemon flavor: lemon zest in the dough and fresh lemon juice in the glaze add a clean citrus finish that keeps the cookies from tasting overly sweet.

Ingredient Notes

Blueberries: fresh or frozen blueberries work; I prefer fresh since they hold their shape better. Because blueberries vary in size and moisture, weighing them with a food scale gives the most consistent results. If using frozen, they will release more juice, which can tint the dough purple. Keep frozen blueberries in the freezer until ready to use and toss them lightly in flour before folding in to reduce excess moisture and prevent clumping.
Lemon zest: this gives the cookies a bright, citrus flavor. Use a zester or fine grater to scrape only the outer colored part of the peel. The white part underneath can be bitter. If you have extra, use it to make my delicious lemon caper pasta or chicken limone.
Lemon juice: this gives the glaze a bright citrus flavor. Use freshly squeezed juice because it's brighter and more balanced than bottled. Don't let extra go to waste, you can use it to make this whipped ricotta dip.
Unsalted butter: use room temperature butter so it creams evenly with the other ingredients. I prefer grass-fed butter for its richer flavor, which enhances the lemon and blueberry. It's a top tip I use when baking, like with my walnut biscotti.
Powdered sugar: either "powdered sugar" or "confectioners sugar" can be used. I prefer products made with tapioca instead of cornstarch because of it's subtle sweetness and smooth texture. It also absorbs liquid easily, creating a thick, smooth glaze without any cooking. If you have extra, use it to make these Italian wedding cookies.

Substitutions and Variations

Add chopped nuts: this gives depth and crunch to the cookies. Chopped pecans, almonds, or walnuts are great options. You can toast them beforehand to enhance the deep, nutty flavors.
Mix in poppy seeds: these pair well with lemon and blueberry. They bring a pop of texture and a subtle nuttiness that enhances the berry and citrus flavors.

Instructions

A baking sheet is lined with parchment paper.

Step 1: Preheat the oven to 350°F (177°C) and line a baking sheet with parchment paper.

Flour, baking powder, baking soda, and salt are whisked together.

Step 2: Add the flour, baking powder, baking soda, and salt to a medium-sized bowl. Whisk until combined.

Step 3: Using a handheld or stand mixer with a paddle attachment, cream the butter and sugar together on medium-high speed until fluffy, about 2 to 3 minutes.

Eggs, vanilla extract, and lemon zest are mixed into the cookie dough.

Step 4: With the mixer still on medium-high speed, add the eggs, vanilla extract, and lemon zest. Beat until well combined.

The dry ingredients are mixed into the wet ingredients.

Step 5: With the mixer on low speed, gradually add the dry ingredients. Mix until just combined.

The blueberries are folded into the cookie dough with a spatula.

Step 6: Gently fold the blueberries into the dough with a spatula or wooden spoon until they are evenly distributed.

Scoops of cookie dough are placed on a baking sheet two inches apart.

Step 7: Use a 3 tablespoon cookie scooper to scoop balls of dough onto the prepared cookie sheet. Space them at least 2 inches apart so they don't spread into each other when baking.

Step 8: Bake the cookies for 10 to 13 minutes, or until the edges turn a light golden color. Allow the cookies to cool for 5 minutes on the baking sheet before transferring to a wire rack.

Powdered sugar and lemon juice are whisked together to form a glaze.

Step 9: Add the powdered sugar and lemon juice to a small bowl. Whisk together until a smooth glaze forms.

A spoon drizzles glaze across the top of the cookies.

Step 10: Once the cookies are completely cool, use a small spoon to drizzle the glaze across the top of each cookie. Allow the glaze to set a few minutes before serving. Enjoy!

Storage

Refrigerator: store in an airtight container in the refrigerator for up to 1 week. Because of the moisture from the blueberries, the cookies hold their shape best when refrigerated.
Freezer: freeze for up to 3 months in an airtight container placing parchment between layers to prevent sticking. Thaw in the refrigerator before serving.

Expert tips

Weigh the blueberries for consistency: since berries vary in size and moisture, weighing them with a food scale helps keep the amount consistent and prevents excess moisture in the dough.
Use frozen blueberries straight from freezer: keep frozen blueberries in the freezer until ready to use to prevent excess moisture in the dough. Toss lightly in a tablespoon of flour to reduce excess liquid and prevent clumping for even distribution.
Zest only the outer lemon peel: use a zester or fine grater to remove only the outer colored peel. Avoid the white pith which can be bitter.
Measure the flour accurately: use a food scale to measure the flour in grams for the most accurate results. If measuring by cups, spoon the flour into the measuring cup without packing it down. Then level off the top.

FAQ

Why did my lemon blueberry cookies turn purple?

Lemon and blueberry cookies can turn purple if frozen blueberries are used. They release more juice as they bake, tinting the dough. This is normal and does not affect the flavor. I love how the purple color contrasts beautifully with the white glaze!

Do I need to chill the dough when making lemon and blueberry cookies?

No, you do not need to chill the dough when making lemon and blueberry cookies. This dough is best baked right away. As blueberries sit, they release moisture, which can affect the texture of the cookies.

Can I skip the glaze when making blueberry lemon cookies?

Yes, you can make blueberry lemon cookies without the glaze. Although the lemon glaze adds brightness and texture, these cookies are still delicious without it!

Why did my lemon blueberry cookies bake unevenly?

Lemon blueberry cookies can bake unevenly if the blueberries release excess moisture into the dough. Large juicy berries, or thawed frozen berries, can create wetter pockets that affect baking. For best results, weigh the berries with a food scale. If using frozen, keep them in the freezer until ready to use and toss lightly in flour before folding into the dough.

Serving Suggestions

Here are my favorite ways to serve lemon blueberry cookies:

As a light dessert after dinner: serve after a simple Italian meal like chicken Milanese, bucatini cacio e pepe, or caprese salad with burrata.
On a cookie tray: pair with classic Italian cookies like pignoli or Italian ladyfingers for a balanced mix of textures and flavors.
As part of a dessert trio: serve alongside a creamy dessert like coffee panna cotta or chocolate budino for a well-rounded finish.
With ice cream: crumble over no egg vanilla ice cream or espresso ice cream for a rich complement to the bright cookies.
