Equipment

  • hand or stand mixer
  • large 3TB cookie scoop

Ingredients

Cookies

  • 16 tablespoon butter, softened 2 sticks
  • 1.25 cup granulated sugar
  • 1 large egg
  • 1 large egg yolk, discard the whites
  • 1 tablespoon key lime zest
  • 2.5 cup all-purpose flour 318g in weight
  • 2 teaspoon baking powder
  • 3/4 teaspoon salt

Frosting

  • 16 tablespoon butter, softened 2 sticks
  • 1 teaspoon vanilla extract
  • 1/4 cup key lime juice
  • 1 zested key lime
  • 1/4 teaspoon salt
  • 3.5 cup powdered sugar

Instructions

  • To start, cream the butter with the sugar. Then, add in the egg, yolk and the key lime zest. In a separate bowl, combine the flour, baking powder and the salt. Now, combine the dry and wet ingredients until the dough is formed.
  • Preheat the oven to 350℉.
  • On a lined sheet pan, scoop the dough with a large cookies scoop and place the scoops on the baking sheet. Give each cookie about 2 inches to spread. Place the cookies in the oven and bake for 10-12 minutes. When you notice the cookies browning slightly at the edges after they have spread, pull them out.
  • Allow the cookies to cool completely once removed from the oven. While they are cooling make the frosting.
  • In a large bowl, add in the softened butter and cream the butter with the key lime juice, zest, vanilla extract and the salt. Once that's smooth, start to add in the powdered sugar until the buttercream is creamy.
  • After the cookies have cooled, use a pipping bag and add the frosting to the cookies. Serve and enjoy.
