Marbled Heart Sugar Cookie Cutouts

Heat oven to 375°F.

In large bowl, mix cookie mix, flour, butter and egg with spoon until soft dough forms. Divide dough into 3 pieces. Place 2 pieces of dough into 2 small bowls. Tint 1 bowl pink and 1 bowl purple by stirring in each food color.

On floured surface, drop tablespoons of each dough in random pattern to make large rectangle. Dough pieces should be just touching together. Push dough rectangle toward center on all sides to make 6x5-inch rectangle. Roll dough 1/4 inch thick to create marbled pattern. Cut with 3-inch heart-shaped cookie cutter; place cutouts 2 inches apart on ungreased cookie sheets. Sprinkle with sugar. Press any leftover scraps together, and reroll on floured surface to make more cookies.

Bake 7 to 9 minutes or until edges are light golden brown. Cool 2 minutes; remove from cookie sheets to cooling rack. Cool completely, about 15 minutes.
