Give your cookies and cakes the royal treatment by decorating them with a perfect batch of fast and easy-to-make royal icing. This mix takes the guesswork out of getting the ideal consistency icing for your decorating project. Just follow the directions by adding water or milk and you can make thin or flood consistency icing for sugar cookies. The icing dries hard so your cookies are easy to stack and store. Or mix to a stiff consistency to pipe flowers and more. It’s also the perfect icing to build and decorate gingerbread houses for the holidays. Icing can be stored in the refrigerator for up to 5 days after you make it.
