Key Lime Cookies

Key lime cookies are bite-sized treats with a tender crumb and bright, tangy flavor. They are made by mixing butter, sugar, lime zest, and flour, then shaping and baking until lightly golden. The final cookies have a crisp exterior and a soft, flavorful interior, infused with zesty lime aromatics.

Ingredients Equipment Method Notes

Ingredients
  

  • 1 cup unsalted butter softened
  • 1 cup granulated sugar
  • 2 teaspoons lime zest freshly grated
  • 1 large egg
  • 2 1/2 cups all-purpose flour
  • 1/2 teaspoon baking powder

Equipment

  • Mixing bowls
  • Electric mixer or whisk
  • Baking sheet
  • Parchment paper or silicone baking mat
  • Cookie scoop or tablespoon
  • Cooling rack

Method
 

  1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone mat.
  2. In a large mixing bowl, beat the softened butter and sugar together using an electric mixer or whisk until the mixture is light and fluffy, about 2-3 minutes and slightly pale in color.
  3. Stir in the freshly grated lime zest and then add the egg, beating well after each addition until the mixture is smooth and combined.
  4. In a separate bowl, whisk together the flour, baking powder, and a pinch of salt if desired.
  5. Gradually add the dry ingredients to the wet mixture, mixing on low speed or folding until just combined and a soft dough forms.
  6. Using a cookie scoop or tablespoon, portion out the dough and place the balls onto the prepared baking sheet, spacing them about 2 inches apart for spreading.
  7. Gently flatten each cookie slightly with your hand or the bottom of a glass for even baking.
  8. Bake in the preheated oven for 10-12 minutes, or until the edges are just lightly golden and the centers are set.
  9. Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely. The cookies will firm up as they cool, with a tender interior and crisp exterior.
  10. Once cooled, enjoy these bright, tangy cookies on their own or with a cup of tea for a refreshing treat.

Notes

Store the cookies in an airtight container at room temperature for up to 3 days. For longer freshness, refrigerate them and bring to room temp before serving.
