2 1/2 cups all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup unsalted butter, room temperature
1 cup granulated sugar
1 large egg
2 teaspoons key lime juice
1 teaspoon lime zest
1 cup powdered sugar (for glaze)
1 tablespoon key lime juice (for glaze)
Lime zest (for garnish)

How to Make Key Lime Cookies

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking soda, and salt until well combined.
In a large bowl, cream the unsalted butter and granulated sugar using a hand mixer or stand mixer until the mixture is light and fluffy, about 2-3 minutes.
Beat in the egg, key lime juice, and lime zest until fully incorporated and smooth.
Gradually add the dry flour mixture to the creamed mixture, mixing until just combined. Be careful not to overmix; the dough should be soft and slightly sticky.
Using a spoon or cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about two inches apart.
Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden and the centers look set.
Allow the cookies to cool on the baking sheet for about 5 minutes, then transfer them to a wire rack to cool completely.
For the glaze, whisk together the powdered sugar and key lime juice in a small bowl until smooth and glossy. Drizzle over the cooled cookies and garnish with additional lime zest for a pop of color and flavor.

Tips for Best Results

Make sure your butter is at room temperature to ensure a smooth and even mix, leading to tender cookies.
Measure your flour accurately; too much flour can lead to dry cookies. Spoon the flour into your measuring cup and level it off gently.
Keep an eye on the baking time; cookies will continue to bake slightly after being taken out, so look for lightly browned edges and a slightly soft center.
For added flavor, consider mixing in some white chocolate chips or macadamia nuts for a delightful twist.

Variations and Substitutions

For a gluten-free alternative, you can substitute the all-purpose flour with a gluten-free blend. Additionally, if you’re out of key limes, regular limes work well too, although the flavor might not be quite as unique. For a richer taste, feel free to add a teaspoon of vanilla extract to the dough mixture.

How to Serve It

These cookies make a perfect addition to any dessert platter and are delightful served with a scoop of vanilla ice cream. Pair them with iced tea or lemonade for a refreshing treat, or enjoy them on their own while basking in the sunlight.

How to Store It

Store the cookies in an airtight container at room temperature for up to a week. If you want to keep them longer, freeze the unglazed cookies for up to three months. Thaw and glaze before serving for the freshest taste.

Final Thoughts

These Key Lime Cookies are sure to awaken your taste buds and elevate any dessert table. Their bright flavor and delightful texture make them an irresistible treat. I hope you enjoy making them as much as I do, bringing a little sunshine into your kitchen!
