A brand of frosted cereal produced by the Kellogg's Company. The first flavor, Cinnamon Bun, was introduced in 2005, and was successful enough that two temporary flavors followed, Fudge Ripple and Peanut Butter. The cereal was made mainly with sweetened cornmeal, whole oat grain, and whole wheat grain, with a flavored topping that corresponds to the variety. The pieces in each version are shaped to resemble cinnamon buns. In 2009 Mini Swirlz was discontinued by Kellogg's.
