Key Lime Cookies

Key Lime Cookies combine the tangy zest and juice of key limes with white chocolate chips in a soft, slightly chewy cookie. The dough is chilled before baking to maintain shape and texture, resulting in 20–24 small, flavorful iced cookies. A lime glaze and zest topping add brightness and sweetness, enhancing the citrus character while balancing the buttery base.

Description

This recipe uses all-purpose flour, baking soda, and salt combined with butter, granulated sugar, and light brown sugar to create a soft cookie dough. Key lime zest and juice offer a distinct tart and aromatic citrus flavor, while white chocolate chips add a creamy sweetness that complements the lime. The inclusion of an egg and vanilla extract enriches the cookie's texture and depth.

Chilling the scooped cookie dough for 30 minutes before baking helps the cookies keep their shape and develop a tender crumb. Baking at 375°F for 7–8 minutes yields cookies that are set with lightly golden bottoms. After baking and cooling, a glaze made from powdered sugar and key lime juice is drizzled on top, with extra lime zest sprinkled over for added visual appeal and flavor layering.

These cookies fit nicely into dessert assortments, offering a refreshing citrus note alongside richer treats. Their moderate size and balance of tartness and sweetness make them suitable for parties, afternoon tea, or gifting.

Ingredients

Servings

For the Cookies:

  • 1 1/2 cup all-purpose flour 195 grams
  • 1/2 teaspoon baking soda 3 grams
  • 1/2 teaspoon salt 4 grams
  • 1/2 cup butter room temperature) 4 ounces, unsalted
  • 1/4 cup granulated sugar 50 grams
  • 1/4 cup light brown sugar 50 grams
  • 1 large egg
  • 1/2 teaspoon vanilla extract
  • 1 teaspoon key lime zest (or zest of 1 key lime)
  • 2 1/2 tablespoons key lime juice
  • 1/2 cup white chocolate chips 90 grams

For the Lime Glaze:

  • 3/4 cup powdered sugar 86 grams
  • 1 - 1 1/2 tablespoons key lime juice
  • lime zest to sprinkle on top

Instructions

  1. Line a light colored baking sheet with a nonstick baking mat. (Dark baking sheets make the cookies brown fast on the bottom.)
  2. In a small bowl, add the flour, baking soda and salt and mix together until combined.
  3. In another bowl, add the butter and sugar and mix until the texture is smooth and creamy. Add in the egg, vanilla, lime juice and zest and mix until combined.
  4. Slowly add in the dry ingredients into the wet ingredients and mix until well combined.
  5. Add in the white chocolate chips and fold until mixed in.
  6. Use a cookie scoop to place the cookie dough in tablespoon (1 to 1 1/2 tablespoons is good for these cookies) scoops on the baking sheet. You should get 20-24 cookies.
  7. Refrigerate the scooped cookie dough for 30 minutes.
  8. Preheat oven to 375ºF.
  9. Once the cookie dough is chilled, roll the scoops into smooth balls. Don't handle the dough too much, just roll for a few seconds to get the ball smooth.
  10. Bake for 7-8 minutes (mine were done in 7). Do not overbake! Allow the cookies to cool a few minutes and then transfer to a cooling rack to finish cooling.
  11. Once cooled, mix together the powdered sugar and 1 tablespoon of lime juice to form a glaze. Add the 1/2 tablespoon of lime juice if needed to get it to a drizzling consistency (I usually use 1 1/2 tablespoons). Drizzle teaspoon amount of glaze on each cookie, sprinkle with zest and allow to set so the icing can harden. Enjoy!
