Recipe Note: Make smaller "pizzas" for gift giving using greased 8-inch round or heart shaped pans. Or form cereal into a large heart (free form style!) on a greased serving tray or baking sheet.

*Use ready-to-decorate canned icings with tips attached for a quick and mess free way to "write" as well as make borders and other decorations!
