Vanilla Sugar Cookies with Glaze

1 cup (2 sticks) butter, softened
1 1/2 cups sugar
2 teaspoons cream of tartar
1 teaspoon baking soda
1/4 teaspoon salt
2 eggs
1 teaspoon vanilla
2 3/4 cups flour
additional sugar for rolling

Beat butter in bowl with mixer until light and fluffy. Add sugar, cream of tartar, baking soda, and salt; beat until well blended. Next beat in eggs and vanilla. Gradually stir in flour until well mixed. Refrigerate dough 2 hours (or till firm). Preheat oven to 400 degrees. Shape dough into 1 inch balls. Roll in sugar (sometimes I omit that part), and place 2 inches apart on ungreased baking sheets. Bake 6-8 minutes or until lightly browned.

3-4 teaspoons milk
1/2 teaspoon vanilla
