Krusteaz Fat-Free Wild Blueberry Muffin Mix makes moist, fluffy muffins with real wild Maine Blueberries. Delicious and free of unwanted fats, these muffins are a perfect brunch companion and come in a pack of 12, 15.8-ounce boxes. The Krusteaz story began in 1932 when a group of women from a Seattle bridge club created an easy-as-pie, just-add-water crust that was an industry first. Today, Krusteaz remains a family-owned business that stands for innovation, premium ingredients and simple-to-make mixes that fit every occasion. Their product line includes pancakes, waffles, muffins and quick breads, cookies, dessert bars, cornbread, crumb cakes and more. Every box invites you to âSeize the What Ifâ¦â and have fun sharing these creations in the kitchen, getting a little messy, fueling creativity and enjoying all the possibilities Krusteaz mixes bring to the table.
