Vanilla-Butter Sugar Cookies

Directions

1. Cream butter and sugar until light and fluffy, 5-7 minutes. Beat in eggs and vanilla. In another bowl, whisk flour, salt, baking soda and cream of tartar. Gradually beat into creamed mixture. Refrigerate, covered, for 30 minutes.
2. Preheat oven to 350°. On a lightly floured surface, roll dough to 1/4-in. thickness. Cut with floured 2-1/2-in. cookie cutters. Place 1 in. apart on ungreased baking sheets. Bake 10-12 minutes. Cool on wire racks.
3. For frosting, beat confectioners' sugar, butter, vanilla and enough milk to reach desired consistency. If desired, add a few drops of food coloring. Cut a small hole in the tip of a pastry bag or in a corner of a food-safe plastic bag; transfer frosting to bag. Pipe decorations. Sprinkle with colored sugar.
