- 1/2 cup butter
- 1 cup white sugar
- 1 egg
- 1 egg yolk
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1/4 cup fresh lime juice
- 1 1/2 teaspoons grated lime zest

Preheat oven to 350 degrees F (175 degrees C). Grease cookie sheets.
In a large bowl, cream butter, sugar, egg, and egg yolk until smooth. Stir in lime juice and lime zest. Combine the flour, baking powder, and salt; blend into the creamed mixture. Form dough into 1/2 inch balls, and arrange on the prepared cookie sheet.
Bake 8 to 10 minutes in the preheated oven, or until lightly browned. Cool on wire racks. Sift confectioners' sugar over cookies while still warm.
