Never-Fail Cutout Cookies

Directions

1. Beat butter, cream cheese and sugar until light and fluffy, 5-7 minutes. Beat in egg yolks and vanilla. Gradually beat in flour. Divide dough into 4 portions; shape each into a disk. Cover; refrigerate until firm enough to roll, about 30 minutes.
2. Preheat oven to 350°. On a lightly floured surface, roll each portion of dough to 1/4-in. thickness. Cut with floured 3-in. holiday cookie cutters. Place 1 in. apart on ungreased baking sheets.
3. Bake until edges are light golden, 12-14 minutes. Cool on pans 5 minutes. Remove to wire racks to cool completely.
4. For frosting, beat confectioners' sugar, butter, shortening, vanilla and enough milk to reach desired consistency. If desired, tint with food coloring. Spread or pipe over cookies. Decorate as desired.
