Decorator frostings are typically sold in spreadable tubs and whipped tubs, and some are available in ready-to-use pastry/frosting bags that include a built-in piping tip for decorating.
Follow the product label, but many items advise refrigerating opened frosting. Product instructions commonly state to refrigerate opened canned frosting or a used frosting bag and use within up to 2 weeks.
Ready-to-use frosting bags commonly include a built-in star piping tip in the bag, which lets you pipe borders, lettering, stars, and similar patterns without needing separate tips.
Decorator frostings are intended for use on cakes, cupcakes, cookies, brownies, and birthday cakes across the available varieties.
Novelty finishes include rainbow chip (with colorful chips), hot pink sanding-sugar frostings, unicorn frostings with long colorful sprinkles, and other colorful Funfetti-style varieties.
