- Unsalted butter (1 cup): Softened to help create a tender, rich base for your cookies.

- Key lime juice (2 tablespoons): Delivers the essential tartness and vibrant lime flavor.
- Key lime zest (1 tablespoon): Boosts aroma and intensifies that fresh citrus profile.
- All-purpose flour (2 1/2 cups): The main structure component, providing the perfect cookie texture.
- Baking powder (1/2 teaspoon): Helps the cookies rise and remain soft.
- Baking soda (1/4 teaspoon): Works alongside baking powder to create just the right lift.

How to Make Key Lime Cookies Recipe
Step 1: Cream the Butter and Sugar
Start by beating the softened butter and granulated sugar together in a large bowl until the mixture is light and fluffy. This step is crucial because it incorporates air, giving your cookies their tender, melt-in-your-mouth texture.
Step 2: Add Egg and Key Lime
Next, beat in the egg, followed by the key lime juice and zest. This combination infuses the dough with bright citrus flavor and moisture, ensuring every bite bursts with that irresistible lime tang.
Step 3: Combine the Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. These dry ingredients create the necessary structure and balance so your cookies rise beautifully without becoming too dense.
Step 4: Mix Wet and Dry Ingredients
Gradually add the dry mixture to the wet ingredients, stirring just until a soft dough forms. Be careful not to overmix, which can make cookies tough. This balance keeps the cookies tender and soft.
Step 5: Chill the Dough
Cover your dough and chill it for 30 minutes. Chilling firms up the dough, making it easier to handle and helping the flavors meld beautifully.
Step 6: Preheat and Prepare Baking Sheets
While the dough chills, preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper. The parchment ensures your cookies bake evenly and don’t stick.
Step 7: Shape and Coat the Cookies
Roll tablespoon-sized pieces of dough into balls, then gently coat each ball in powdered sugar. This not only adds sweetness but creates that lovely crackled look and a delicate texture on the outside.
Step 8: Bake and Cool
Place the sugar-coated dough balls on the baking sheets, spacing them about 2 inches apart. Bake for 10 to 12 minutes until the edges turn lightly golden. Let the cookies cool on the sheet for 5 minutes before transferring to a wire rack to cool completely, allowing them to set perfectly.
How to Serve Key Lime Cookies Recipe

Garnishes
A dusting of extra powdered sugar right before serving adds an elegant, snowy finish. Fresh lime slices or zest curls on the side can amp up the visual appeal and reinforce that citrusy vibe.
Side Dishes
These cookies pair beautifully with a refreshing glass of iced tea or a cool cup of minty limeade. They also complement lighter desserts like sorbet or a dollop of whipped cream for a true lime celebration.
Creative Ways to Present
Consider stacking these cookies with a layer of lime-flavored cream cheese filling for a cookie sandwich twist. You can also serve them alongside fresh berries or a drizzle of white chocolate for a more indulgent treat that’s sure to impress guests.
Make Ahead and Storage
Storing Leftovers
Keep your Key Lime Cookies in an airtight container at room temperature, and they’ll stay fresh and soft for up to five days. This makes them a perfect make-ahead treat for busy weeks or last-minute guests.
Freezing
If you want to keep these cookies longer, freeze the unbaked dough balls after coating them in powdered sugar. When ready to bake, simply thaw slightly and pop them into the oven. Baked cookies can also be frozen, but the dough does maintain freshness best.
Reheating
To enjoy cookies that taste like they just came out of the oven, warm them for 10 to 15 seconds in the microwave. This brightens flavors and softens the texture just enough without making them soggy.
FAQs
Can I use regular lime instead of key lime in this recipe?
Yes, regular lime juice and zest work as a substitute, though key limes have a uniquely tart and floral flavor that really defines the recipe’s character.
Why do I need to chill the dough before baking?
Chilling helps the dough firm up, making it easier to handle and roll into balls. It also lets the flavors develop fully and keeps the cookies from spreading too much while baking.
What makes these cookies soft instead of crunchy?
The balance of butter, sugar, and gentle leavening agents, along with careful baking time, ensures these cookies remain tender and soft rather than crisp or crunchy.
Can I add lime extract for extra flavor?
Absolutely! A few drops of lime extract can intensify the lime flavor, making these cookies even more vibrant and citrus-forward.
How long do these cookies stay fresh?
Stored properly in an airtight container at room temperature, they stay deliciously fresh for about five days, perfect for enjoying over several days or sharing with friends.
