LOVE THIS PLACE!! Now they have GF cupcakes too!! Don't know what the other reviewers are talking about. I have celiac and have never experienced a reaction. They use garbanzo and rice flour.

I personally haven't purchased from them since the owner told me (when they were at the farmer's market location) about a new GF flour he was experimenting with: spelt. :-/
