How-to for Marble Icing on Cookies
Time to swirl!
Starting in the center, gently pull a toothpick through both colors of icing to swirl the colors together. If you’ve piped polka dots, pull the toothpick in random curves for a casual marbled design. If you’ve piped stripes, pull the toothpick in straight lines perpendicular to the piped stripes for a scalloped pattern. Wipe the toothpick clean as needed.
