Rainbow Rounds

2 cups butter, softened

2 1/4 cups sugar

3 egg yolks

1 large egg

1 Tbs. vanilla

1 tsp. salt

5 1/4 cups all-purpose flour

1/2 cup each red, orange, yellow, green, blue, and purple crystal sugars

1. In large bowl, with mixer on high, beat butter and sugar until light and fluffy, about 3 minutes. Add egg yolks, egg, vanilla, and salt, and beat well to combine. With mixer on low, gradually beat in flour. Divide dough into 6 equal pieces, roll each piece into an 8-inch log, cover with plastic wrap, and refrigerate for 3 hours.
2. Heat oven to 350°F. Working with 1 roll at a time, unwrap dough and roll in 1 color of crystal sugar. Cut logs into 1/4 inch thick slices, and place on ungreased baking sheet 1/2 inch apart. Bake 12 to 16 minutes, until golden. Let cool 5 minutes on baking sheet, transfer to wire rack, and let cool completely. Repeat with remaining dough, using a different color for each roll. Makes about 12 dozen cookies.
