Blue Ribbon Sugar Cookies

Step 1

Heat oven to 375°F.

Step 2

Combine butter, powdered sugar and 1/2 cup sugar in bowl. Beat at medium speed, scraping bowl often, until creamy. Add egg and vanilla; continue beating until well mixed. Add flour, cream of tartar and baking soda; beat at low speed until dough forms a ball.

Step 3

Shape dough into 1-inch balls. Place, 2 inches apart, onto ungreased cookie sheets. Flatten to about 1 1/2 inches with bottom of glass dipped in sugar; sprinkle with decorator sugars, if desired. Bake 7-9 minutes or until edges are lightly browned. Let stand 1 minute on cookie sheet; remove to cooling rack.
