<<Disclaimer: Verify this information before applying it to your situation.>> There was not a lot of response to my question of whether or not confectioners' glaze was gf. Below are the reponses I did get. In addition, I had called Betty Crocker on one of the containers of sprinkles that I had. It contained confectioners' glaze and I was told they were gluten-free. Sidona Ryan/San Diego, CA 1. In cooking terms, confectioners' glaze is confectioner's sugar and a liquid--milk, lemon juice, rum. confectioner's sugar contains corn starch Ann 2.Dear Sidona-- We met with a dietician around Halloween and asked her if we could give our 4-year-old son who has Celiac Disease the candy corn I had bought. She looked at it, saw that it had "confectioners' glaze" and said no, that c.g. wasn't g.f. So to speak. I can't remember why, but I won't buy anything with it anymore. Hope that's helpful. Claire L.
