  • Yield:makes about 30 cookies
  • Active time: 20 minutes
  • Total time:1 hour 40 minutes


  • 1 cup (5 ounces) all purpose flour
  • 1/4 teaspoon salt
  • 1 stick (8 tablespoons) unsalted butter, at room temperature
  • 1/4 cup (1 2/3 ounces) sugar
  • 2 tablespoons confectioners sugar
  • 1 tablespoon vanilla extract
  • 1 egg yolk
  • 2 teaspoons zest and 1 tablespoon juice from about 4 small key limes


  1. 1.

    In a small bowl, whisk together flour and salt; set aside. In a large bowl, cream together butter, sugar, and confectioners sugar until creamy, about 3 minutes. Beat in vanilla, egg yolk, juice, and zest until combined. Add flour and salt mixture and beat just until dough comes together. Form dough into two 1 1/2-inch wide logs and wrap in plastic wrap. Let chill in refrigerator at least one hour.

  2. 2.

    Adjust oven rack to middle and upper positions and preheat oven to 350°F. Line two baking sheets with parchment paper. Slice logs into 1/4-inch coins. Bake until coins are just golden on the bottom, about 20 minutes. Let cool for 5 minutes then transfer to a wire rack to finish cooling.
