About

Built on a 40-year family flour legacy, New York’s Steiner’s Baking Co. makes clean-label gluten-free baked goods and flour for cafés, bakeries, and home bakers. The women-led company grew from founder Nanci Steiner’s effort to create a coffee cake so moist and flavorful that nobody would suspect it was gluten-free, with its German sour cream coffee cake becoming a signature. Steiner’s products are also made without nuts and are kosher dairy.
