A fresh look at gluten-free flour, snacks & baked goods Steiner’s Baking Co. is a gluten-free flour, snacks & baked goods company using its proprietary all-purpose flour blend in its products. At Steiner’s our signature sweet creation, coffee cakes, are made with real ingredients. No artificial flavors or preservatives go into our cakes or any of our snacks and baked goods, giving them a fresh, right-out-of-the-oven taste. In addition to being certified UD Kosher and gluten-free, we are also nut-free – though we won’t say the same about our staff.
