Do you know what drives me to create Pretzilla products that i'm proud carry the Miller Baking name? History. For nearly 100 years, my family-owned Milwaukee bakery has been committed to crafting great tasting baked goods with honest ingredients. Quality and service aren't just mottos we stick on a poster - we grind daily to honor them. The payoff of those extra steps is hearing from you about all the ways you enjoy Pretzilla. - Brian Miller, Owner. pretzilla.com. Share your creations! Facebook. Instagram. Twitter.
