Today, Krusteaz remains a family-owned business that stands for innovative products, premium ingredients and easy-to-make mixes to fit every occasion. The product line includes pancakes, waffles, muffins and quick breads, cookies, dessert bars, cornbread, crumb cakes and more. Every box invites consumers to “Seize the What If…” and have fun in the kitchen, get a little messy, fuel their creativity and enjoy the possibilities Krusteaz mixes bring to the table.
