YOUR SIMPLE, 6-INGREDIENT LIST

The magic of these lemon meltaway cookies with cornstarch lies in the perfect balance of a few simple ingredients.

For the Meltaway Cookie Dough:

• Unsalted Butter, room temperature: The foundation of flavor and tenderness. It must be truly at room temp for a smooth dough.
• Confectioners’ Sugar: Using powdered sugar, not granulated, is key for the fine, delicate texture.
• Cornstarch: The star ingredient! This is what creates the unique, meltaway mouthfeel by tenderizing the gluten.
• All-Purpose Flour: Provides the cookie’s structure.
• Fresh Lemon Zest and Juice: For that vibrant, true lemon flavor. Bottled juice won’t give the same bright pop.

For the Lemon Glaze (Optional but Recommended):

• More Confectioners’ Sugar & Lemon Juice: Creates a sweet-tart shell that complements the tender cookie perfectly.

THE FEW TOOLS YOU’LL NEED

• Large mixing bowl
• Electric hand mixer or stand mixer
• Spatula
• Plastic wrap or parchment paper
• Baking sheets
• Wire rack for cooling

STEP-BY-STEP: MAKING PERFECTLY TENDER COOKIES

Follow these simple steps for the most tender Lemon Meltaway Cookies with Cornstarch you’ve ever had.

CREAM THE BUTTER AND SUGAR

Start by preheating your oven to 350°F (175°C) and lining your baking sheets. In your large bowl, beat the room-temperature butter with an electric mixer on medium speed until it’s smooth and creamy, about 1 minute. Add the confectioners’ sugar and beat for another 2-3 minutes until the mixture is very light and fluffy. This step incorporates air and is crucial for the texture.

INCORPORATE THE LEMON AND DRY INGREDIENTS

Add the fresh lemon zest and juice to the butter mixture and beat until combined. In a separate bowl, whisk together the all-purpose flour and the key ingredient: cornstarch. Gradually add this dry mixture to the wet ingredients, mixing on low speed just until the dough comes together and no dry flour remains. Be careful not to overmix.

SHAPE, CHILL, AND BAKE

The dough will be soft. For uniform cookies, scoop rounded teaspoonfuls of dough and roll them gently into balls. Place them about 2 inches apart on your prepared baking sheets. You can leave them as balls for a more rustic look, or for a classic look, gently flatten each ball slightly with the bottom of a glass. Bake for 10-12 minutes, just until the bottoms are very lightly golden and the tops look set. They should not brown.

COOL AND GLAZE

Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. Once completely cool, you can enjoy them as is. For the classic finish, whisk together the glaze ingredients until smooth and drizzle or spread a thin layer over each cookie. The glaze will set in about 30 minutes.

THE SECRET BEHIND THE CORNSTARCH IN LEMON MELTAWAY COOKIES

Why cornstarch? In baking, cornstarch is a tenderizing powerhouse. It inhibits gluten development in the flour, resulting in a cookie with a finer, more delicate crumb that literally “melts” on your tongue. It’s what separates a good lemon cookie from a truly unforgettable Lemon Meltaway Cookie with Cornstarch. Don’t be tempted to skip it or substitute it.

PRO TIPS FOR PERFECT LEMON MELTAWAY COOKIES EVERY TIME

• Butter Temperature is Everything: Your butter should be cool to the touch but soft enough to leave an indent when pressed. Too cold, and your dough won’t cream properly; too warm, and the cookies will spread too much.
• Don’t Over-Bake: These cookies are done when they look just set. They will continue to firm up as they cool. Over-baking is the enemy of the “meltaway” texture.
• Chill for Cleaner Slices: For slice-and-bake logs, wrap the dough and chill for at least 2 hours for clean, round slices.
• Sift Your Sugar: For the smoothest dough and glaze, sift your confectioners’ sugar to remove any lumps.

DELICIOUS VARIATIONS TO TRY

• Lime or Orange Meltaways: Swap the lemon zest and juice for lime or orange.
• Lavberry: Add 1 teaspoon of culinary dried lavender to the dry ingredients for a floral twist.
• Poppy Seed Lemon: Fold in 2 tablespoons of poppy seeds to the dough for a lovely texture and visual appeal.

STORAGE & FREEZING INSTRUCTIONS

Store glazed or unglazed Lemon Meltaway Cookies with Cornstarch in an airtight container at room temperature for up to 1 week. They freeze beautifully for up to 3 months. Freeze baked cookies in a single layer before transferring to a freezer bag. You can also freeze the dough logs, wrapped tightly in plastic, and slice and bake straight from the freezer, adding 1-2 minutes to the bake time.

TROUBLESHOOTING COMMON QUESTIONS

My cookies spread too much. Your butter was likely too warm. Chill the shaped dough balls on the baking sheet for 15 minutes before baking next time.
My cookies are tough/crumbly. This is usually from over-mixing the dough once the flour was added. Mix just until combined.
The dough is too sticky to roll. It’s likely your kitchen is warm. Chill the dough for 20-30 minutes before shaping.
Can I use lemon extract? You can add ½ teaspoon for an extra lemon punch, but do not replace the fresh juice and zest they provide the best flavor.

HOW TO SERVE THESE DELICATE COOKIES

Serve these Lemon Meltaway Cookies with Cornstarch with a cup of tea, coffee, or as a light, elegant dessert after a rich meal. They are perfect for baby showers, bridal teas, holiday cookie trays, or simply as a sweet afternoon treat.

A QUICK NUTRITION NOTE

These are a buttery, indulgent cookie. The recipe makes a large batch of small cookies, perfect for portion control. For a dairy-free version, a high-quality vegan butter can work.
