Ingredients
  

For the Cookies

  • 1 cup all-purpose flour
  • 1/2 cup granulated sugar
  • 1/4 cup unsalted butter, softened
  • 1/4 cup brown sugar
  • 1 large egg
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla extract
  • 1 tablespoon key lime juice

For the Icing

  • 1 cup powdered sugar
  • 1 tablespoon key lime juice for icing

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C).
  • In a medium bowl, whisk together the flour, baking soda, and salt.
  • In a large bowl, beat the softened unsalted butter, granulated sugar, and brown sugar until light and fluffy (about 2-3 minutes).
  • Add the egg, vanilla extract, key lime juice, and key lime zest to the butter mixture and blend until smooth.
  • Gradually mix the dry ingredients into the wet mixture until just combined.
  • Using a cookie scoop or tablespoon, drop rounded tablespoons of dough onto prepared baking sheets lined with parchment paper, leaving space between each cookie.

Baking

  • Bake for 10–12 minutes, or until the edges are lightly golden.
  • Allow cookies to cool completely on a wire rack.

Icing

  • Mix the powdered sugar with a tablespoon of key lime juice until smooth and drizzle over cooled cookies.

Notes

Use fresh key limes for the best flavor. Mix well to avoid dense cookies. Consider adding white chocolate chips or coconut for variations.
