Can I use frozen blueberries instead of fresh?

Yes! You can use frozen blueberries straight from the freezer—don't thaw them first or they'll release too much moisture into the dough. Just know that frozen berries may bleed more color into the dough, creating a slightly marbled effect, which can actually look quite pretty.

Why did my cookies spread too much?

The most common culprit is butter that's too warm. Make sure you cool the melted butter for the full 10 minutes in the refrigerator. Another possibility is measuring the flour incorrectly—too little flour can lead to excess spreading. For best results, use a kitchen scale or spoon flour into measuring cups and level off with a knife.

Can I make the dough ahead of time?

Absolutely! You can refrigerate the dough for up to 24 hours before baking. This actually enhances the flavor as the lemon infuses more deeply. Just bring the dough close to room temperature before scooping and baking, or your cookies may not spread properly.

How do I know when the cookies are done baking?

Look for set edges that are just turning golden brown, while the centers still look slightly underdone. The cookies will continue cooking from residual heat on the baking sheet, and this approach ensures they stay chewy rather than crunchy throughout.

Ingredients You’ll Need

All-purpose flour: The foundation of our cookies, providing structure while keeping them tender.
Cornstarch: A secret ingredient that makes these cookies extra soft and thick.
Baking powder and baking soda: The dynamic duo that gives the perfect rise and texture to these cookies.
Salt: Enhances all the flavors and balances the sweetness.
Granulated sugar: Sweetens the cookies and creates those slightly crispy edges when rolled.
Lemon zest: The star of the show, providing bright, aromatic citrus flavor without making the cookies too tart.
Butter: Use unsalted to control the salt level. Melting it creates a chewier texture than creaming.
Eggs: Provide structure and richness. The extra yolk adds tenderness and chewiness.
Vanilla extract: Rounds out the flavors and adds depth to the lemon.
Blueberries: Fresh ones work best, but frozen will work in a pinch (just don’t thaw them first).
Sugar for rolling: Optional but gives a lovely sparkle and slight crunch to the exterior.

Mixed Berry Version: Replace half the blueberries with raspberries for a mixed berry experience.
Almond Touch: Add 1/2 teaspoon of almond extract alongside the vanilla for a subtle nutty complexity.

How to Make Lemon Blueberry Cookies

Step 1: Prep Your Oven and Butter

Preheat your oven to 375°F (190°C) and line a large baking sheet with parchment paper. Melt the butter in a small bowl and then cool it in the refrigerator for about 10 minutes. This cooling step is crucial—too-warm butter will lead to flat cookies!

Step 2: Combine Dry Ingredients

In a medium bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt until thoroughly combined. This even distribution ensures consistent texture in every cookie.

Step 3: Mix Sugar and Lemon

In a large mixing bowl, whisk the sugar and lemon zest together until it resembles wet sand. This technique infuses the sugar with lemon oils, creating a more intense citrus flavor throughout the cookie.

Step 4: Add Wet Ingredients

Whisk the cooled melted butter into the lemon-sugar mixture until well combined. Then add the egg, egg yolk, and vanilla extract, whisking until smooth. The mixture should look glossy and well-integrated.

Step 5: Combine Wet and Dry Ingredients

Stir the dry ingredients into the wet mixture just until combined. Overmixing can develop gluten and make your cookies tough, so stop when you no longer see dry flour.

Step 6: Add Blueberries

Gently fold in the blueberries until evenly distributed throughout the dough. Be careful not to crush them, as their juice can discolor the dough (though it won’t affect the flavor).

Step 7: Form and Bake

Using a medium cookie scoop, portion the dough into balls (about 2 tablespoons each). If desired, roll each ball in granulated sugar for extra sweetness and sparkle. Place the cookies about 3 inches apart on your lined baking sheet and bake for 10-12 minutes until the edges are set and light golden brown.

Step 8: Cool and Enjoy

Allow the cookies to cool on the baking sheet for 3-4 minutes before transferring to a cooling rack. This brief rest helps them set up without breaking when moved.

Pro Tips for Making the Recipe

Cold Butter After Melting: Don’t skip cooling the melted butter—it prevents flat cookies and helps maintain their shape.
Don’t Overmix: Once you add the flour, mix just until combined to keep cookies tender.
Room Temperature Eggs: This ensures they incorporate evenly without cooling down your butter mixture.
Zest Before Juicing: Always zest your lemons before cutting them for juice (even if you don’t need juice for this recipe).
Cookie Scoop: Using a scoop ensures uniform cookie size, which means even baking times and consistent appearance.

How to Serve

These Lemon Blueberry Cookies make a wonderful addition to almost any occasion:

Perfect Pairings:

Serve with a cup of Earl Grey tea or a glass of cold milk for the perfect afternoon treat. The bergamot in Earl Grey particularly complements the lemon flavor.

Dessert Platter:

Include these on a cookie platter alongside chocolate chip cookies and shortbread for a variety of flavors and textures.

Ice Cream Sandwich:

When completely cooled, sandwich a scoop of vanilla ice cream between two cookies for an elevated summer dessert.

Make Ahead and Storage

Storing Leftovers

Store cooled cookies in an airtight container at room temperature for up to 3 days. Place parchment paper between layers to prevent sticking.

Freezing Cookie Dough

Roll the dough into balls, then freeze on a baking sheet until solid. Transfer to a freezer bag and store for up to 3 months. Bake straight from frozen, adding 1-2 minutes to the baking time.

Freezing Baked Cookies

Fully cooled cookies can be frozen in an airtight container with parchment between layers for up to 1 month. Thaw at room temperature for about an hour before serving.

Reheating

For that fresh-baked taste, warm cookies in a 300°F oven for 3-4 minutes, or microwave individual cookies for 10-15 seconds.
