These Key Lime Cookies are easy to make with the perfect sweet-tart flavor combination. Soft, buttery cookies that taste like fresh key limes and dusted with just a light coating of sugar are the perfect snack and after-school treat.
¼cupkey lime juice(I used Nellie & Joe's Key West Lime Juice)
6teaspoonslime zest,finely grated, divided
Preheat oven to 325 degrees. Line 3 large baking sheets with parchment paper.
In a large bowl of your electric mixer, beat butter with granulated sugar and 1 cup powdered sugar until light and fluffy.
Continue to beat while adding eggs and extracts.
In a medium bowl, combine flour, cornstarch, baking powder and salt.
Add to the butter-sugar mixture, alternately with key lime juice and 4 teaspoons of zest, at low speed until well mixed.
Using a tablespoon or a small cookie scoop, place cookie balls 1" apart on prepared baking sheets.
Bake for 16 minutes or until the bottoms are just starting to turn a light brown. DO NOT OVERBAKE!
While cookies are baking, mix 1 cup powdered sugar with the remaining 2 teaspoons lime zest in a large gallon-sized plastic bag. Rub the two together to impart some of the key lime flavor to the sugar.
Remove cookies from the oven and let cool about 3-4 minutes on baking sheets. Remove carefully then place several at a time in the plastic bag containing powdered sugar mixture and gently toss. Shake excess off then place on wire racks and allow to cool completely.
Store in airtight container.
Add 4 teaspoons of basil to the cookie dough and cook as directed. The basil imparts a nice herbal flavor that complements the zesty key lime.
Love chocolate? Go ahead and add ¾ cup of white chocolate chips to the batter. It makes these buttery cookies even more indulgent. Or just drizzle it on the top!
Love even more lime flavor? Add a lime glaze by mixing ¾ cup powdered sugar with 3 Tablespoons of key lime juice. Drizzle on cooled cookies then sprinkle a little extra zest on top.
Love any citrus-flavored cookies? Try this same recipe replacing the lime juice and zest with either lemons or oranges.
