I bake these cookies every year for the Annual Holiday Cookie Exchange at my girlfriend, Suzanne’s home. They are always a hit. One year I broke tradition and made a different variety of cookie. My friends missed the colorful treats and now they request Rainbow Rounds every year. They are a delicious sweet treat even in the morning with a cup of coffee.
I sometimes change the color of sugars when I bake them during different holidays (Halloween – orange and purple; Valentine’s Day- pink and red; Easter – lavender, pastel pink and mint green). They are even fun to make using your favorite sports team colors. Enjoy!
2 cups butter, softened
2¼ cups sugar
3 egg yolks
1 large egg
1 tsp. Salt
5¼ cups all-purpose flour
½ 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 8” log, cover with plastic wrap and refrigerate for three hours.
2. Heat oven to 350 degrees F. Working with 1 roll at a time, unwrap dough and roll in 1 color of crystal sugar. Cut logs into ¼ inch thick slices, and place on ungreased baking sheet ½ inch apart. Bake 12-16 minutes, until golden. Let cool 5 minutes on baking sheet. Transfer to wire rack, and let cool completely. Repeate with remaining dough, using a different color for each roll.
Makes about 12 dozen.
