Thanks to viewer Natalie for emailing this recommendation: "This is a completely gluten- and dairy-free bakery with a wide variety of baked goods. They also offer a wheat-free and vegan sandwich bread."
Plus, if you like their stuff, you can buy their line of baking mixes! In store, expect to find cakes, muffins, cupcakes, whoopie pies, cookies, loaves, and much more.
For those with other allergen concerns, they do have an allergen information sheet on their site (scroll to the bottom for the link).
