  • 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

  1. Preheat your oven to 350°F (175°C). Prepare a baking sheet by lining it with parchment paper.
  2. In a bowl, mix together the flour, baking soda, and salt until well combined.
  3. In a separate large bowl, cream the butter and granulated sugar together until the mixture is light and fluffy, about 2-3 minutes.
  4. Beat in the egg, key lime juice, and lime zest until fully incorporated.
  5. Gradually add the flour mixture to the creamed mixture, mixing until just combined — don’t overmix to keep your cookies tender.
  6. Using a tablespoon or cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them a couple of inches apart.
  7. Bake for 10-12 minutes, or until the edges are lightly golden. The centers may look a little soft, but they will firm up as they cool.
  8. Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
  9. For the glaze, mix the powdered sugar and key lime juice until smooth. Drizzle over the cooled cookies and sprinkle with additional lime zest for decoration.

Tips for Best Results

  • Room Temperature Ingredients: Ensure your butter is soft but not melted; this aids in achieving the right consistency when creaming.
  • Avoid Overbaking: Keep an eye on the cookies while they bake, as they can quickly go from perfectly soft to overdone.
  • Consistent Size: Use a cookie scoop for uniform cookie sizes, ensuring even baking.
  • Chill the Dough: If your kitchen is warm, consider chilling the dough for about 30 minutes before baking to help maintain shape.
  • Use Fresh Limes: Fresh key limes give the best flavor, so avoid bottled juice if possible.

Variations and Substitutions

For a fun twist, consider adding white chocolate chips or coconut flakes to the dough for added texture and sweetness. You could also try flavored extracts like coconut or vanilla to enhance the flavor. While gluten-free adjustments can be made using a gluten-free flour blend, keep in mind that the texture may differ slightly.

How to Serve It

Key Lime Cookies

These cookies shine on their own but pair beautifully with a cup of tea or coffee. Consider serving them alongside a tropical fruit salad or a scoop of vanilla ice cream for a delightful dessert experience.

How to Store It

Store cookies in an airtight container at room temperature for up to one week. If you want to make them in advance, the dough can be frozen before baking. For longer storage, freeze the baked cookies, separating layers with parchment paper, for up to three months. Add the glaze just before serving to keep the cookies fresh.
