Lemon cookie with lemon glaze :

2 1/2 cups all-purpose flour
1 1/2 cups sugar
1 cup Unsalted Butter, softened
2 eggs
1 tablespoon freshly grated lemon peel
2 tablespoon lemon juice
1 1/2 teaspoons cream of tartar
1 teaspoon baking soda
1/4 teaspoon salt
Glaze
2 1/2 cups powdered sugar
1/4 cup lemon juice

Heat oven to 400°F.
Cream sugar and butter, add remaining wet ingredients and then sift in dry ingredients. Do not over mix.

Chilling the dough is recommended. I put mine in the freezer for 20 min

Drop dough by rounded teaspoonfuls, 2 inches apart, onto ungreased cookie sheets. Bake for 6 to 8 minutes or until edges are lightly browned.

Meanwhile, combine all glaze ingredients in small bowl; stir until smooth. Frost warm cookies with glaze. Sprinkle with additional lemon peel, if desired.
