I came across this cookie recipe on the Land-O-Lakes website, knowing my local grocery store was having a sale on key limes... So I rushed out to the store, bought waaaaay too many key limes and made 80 cookies. HaHa.
1 1/2 cups all-purpose flour
1/2 cup powdered sugar
1/2 cup cornstarch
1 cup LAND O LAKES® Butter, softened
1 tablespoon fresh Key lime juice
2 teaspoons freshly grated Key lime zest
1 1/4 cups powdered sugar
1 teaspoon freshly grated Key lime zest
2 to 3 tablespoons fresh Key lime juice
Freshly grated Key lime zest, if desired
Combine flour, powdered sugar and cornstarch in medium bowl. Set aside.
Beat butter in large bowl at medium speed until creamy. Reduce speed to low; add flour mixture and all remaining cookie ingredients. Beat until dough forms.
Shape dough into two (10-inch) logs on lightly floured surface. Wrap each in plastic food wrap; refrigerate until firm (2 hours).
Heat oven to 350°F. Reshape logs, if necessary. Cut into 1/4-inch slices with sharp knife. Place 1 inch apart onto ungreased cookie sheets. Bake for 9 to 11 minutes or until edges are lightly browned. Cool 1 minute; remove from cookie sheets. Cool completely.
Meanwhile, place powdered sugar and 1 teaspoon lime zest in small bowl. Gradually stir in enough lime juice for desired glazing consistency. Spoon or brush glaze on top of cookies. Let stand until glaze is hardened (15 minutes).
