Ingredients

Scale

Wet Ingredients

  • ½ cup (1 stick) unsalted butter, room temperature
  • 1 large egg
  • 1 large egg yolk
  • 3 tablespoons freshly squeezed key lime juice (from about 12 key limes)
  • 2 teaspoons key lime zest

Dry Ingredients

  • 2 cups all-purpose flour
  • ½ teaspoon baking powder
  • ¼ teaspoon baking soda
  • ¼ teaspoon salt

Additional Ingredients

  • 1 cup + 3 tablespoons granulated sugar, divided
  • 2–3 drops green food coloring or mix of yellow and blue (optional)
  • ⅓ cup confectioners’ sugar

Instructions

  1. Preheat and prepare pans: Preheat your oven to 325°F (163°C). Line two baking sheets with parchment paper or silicone baking mats to prevent sticking.
  2. Cream butter and sugar: In a stand mixer bowl or a large mixing bowl using a hand mixer, cream together the room temperature unsalted butter and 1 cup of granulated sugar until the mixture becomes light and fluffy. This process usually takes about 2 to 3 minutes and is important for a tender cookie texture.
  3. Add eggs and lime: Mix in the whole egg, egg yolk, freshly squeezed key lime juice, and key lime zest. Stir just until everything is combined to maintain a tender dough.
  4. Combine dry ingredients: In a separate large bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt thoroughly to ensure even distribution of leavening agents.
  5. Mix dry into wet: Gradually pour the dry ingredients into the wet ingredients. Mix carefully until just combined to avoid overworking the dough, which can toughen the cookies. If desired, gently fold in the green food coloring or a mix of yellow and blue until the dough turns a light green color.
  6. Prepare sugar coating: Place the remaining 3 tablespoons of granulated sugar in a small bowl, and confectioners’ sugar in a separate small bowl. Using about 2 tablespoons of dough at a time, roll the dough into balls.
  7. Coat dough balls: Roll each dough ball first in the granulated sugar, then in the confectioners’ sugar. This dual coating gives the cookies a sparkling exterior with a slight crunch and a sweet finish.
  8. Arrange and bake: Place the coated dough balls on the prepared baking sheets, spacing them about 2 inches apart to allow for spreading. Bake in the preheated oven for 15-17 minutes, or until the cookies are set but still soft in the center.
  9. Cool: Let the cookies cool on the baking sheet for a few minutes to firm up slightly before transferring them to a wire rack to cool completely. This ensures they hold their shape and achieve the perfect texture.

Notes

  • For the best lime flavor, use fresh key limes and zest just before mixing to preserve brightness and aroma.
  • The green food coloring is optional; you can achieve a natural pale lime color or skip coloring altogether.
  • Don’t overmix once adding dry ingredients to avoid tough cookies.
  • Cookies may look soft when done; they will firm up as they cool.
  • Store cookies in an airtight container at room temperature for up to 3-4 days for optimal freshness.
