1 cup confectioners’ sugar
3/4 teaspoon baking soda
1/4 teaspoon salt
1 cup butter
1 egg
1 teaspoon vanilla
1 tablespoon milk
1/2 cup sugar, optional

Mix flour, cream of tartar, confectioners’ sugar, baking soda and salt. Cut in butter. In a separate bowl, beat the egg. Add vanilla and milk, mixing well. Stir liquid ingredients into dry ingredients until it forms a ball. Cover and let chill in the refrigerator for 2 hours. Form into balls. Place 2 inches apart on an ungreased cookie sheet. Flatten with the bottom of a glass. Bake at 350 degrees for 10 minutes. Be careful not to overcook. Option: When rolling dough into balls, coat dough balls with sugar. Or, frost with your favorite frosting recipe.
