HOLIDAY SWIRL SHORTBREAD COOKIES

Steps:

• In large bowl, beat softened butter, 1/2 cup granulated sugar and the vanilla with spoon until well mixed. Stir in flour until blended. Knead 5 to 10 times or until dough is smooth.
• Divide dough into 3 pieces. Place 2 pieces of dough into 2 small bowls. To one bowl, add green food color; stir or knead to mix color thoroughly into dough. Repeat with red food color and second piece of dough.
• Cut each of the 3 doughs in half. Take one half of each of the doughs, and press together into a ball. Gently knead to mix colors (don't overwork dough or it will lose marbling). Shape into a roll, 6 inches long by 1 1/2 inches in diameter. Spread 1 tablespoon sparkling sugar on plastic wrap; roll log to cover. Wrap dough log tightly with plastic wrap. Repeat forming, shaping and rolling with remaining dough pieces. Refrigerate about 1 hour 30 minutes or until firm.
• Heat oven to 350°F. Unwrap 1 of the dough logs; cut into 1/2-inch slices. Place 2 inches apart on ungreased cookie sheet, reshaping if necessary.
• Bake 9 to 11 minutes or until edges are set. Cool 2 minutes; remove from cookie sheet to cooling rack. Unwrap remaining dough log, and repeat slicing and baking. Cool completely, about 30 minutes. Store covered in airtight container.
