Lemon Poppy Seed Cookies With Lemon Icing Recipe

Directions:

1. Heat oven to 350 degrees F (175 C).
2. In a mixing bowl, cream butter and sugar until smooth. Add egg yolks; then add vanilla and blend. Add rind, poppy seeds (optional), and sour cream.
3. In a separate bowl, mix flour, baking powder, baking soda, and salt. Add to creamed mixture. (Dough will be sticky.)
4. Scoop 2 level tablespoons of dough and roll to form each cookie. Drop onto ungreased cookie sheets, spacing 2 inches apart.
5. Bake until cookies are lightly browned, about 18 minutes. Using a spatula, transfer cookies to a rack and let cool before icing.
6. For icing: Place sugar in a bowl. Whisk in butter and lemon juice until smooth. Drizzle icing over tops of cooled cookies, and let icing harden before serving. Makes about 20 cookies.
