Rainbow Swirl Cookies

Heat oven to 375°F (350°F for dark or nonstick cookie sheet). In large bowl, stir cookie mix and flour until blended. Add butter and egg; stir until dough forms.

Divide dough into 4 portions; place in separate small bowls. Add a few drops blue food color to 1 bowl; stir until dough is evenly tinted, adding more food color as necessary. Repeat with remaining 3 bowls of dough and food colors.

On lightly floured surface, roll each portion of tinted dough into 24 grape-size balls. Press together 4 balls (1 ball of each color) to look like a miniature beach ball. Roll ball into 5-inch rope, then coil rope into spiral shape. Place on ungreased cookie sheet. Repeat with remaining dough. Top cookies with sprinkles.

Bake 8 to 10 minutes or until set. Cool 1 minute; remove from cookie sheet to cooling rack. Cool completely before storing.
