<<Disclaimer: Verify this information before applying it to your situation.>> Yes, many brands of marshmallows should be fine. KIDDS brand (and all 20 some brands they produce and package) are OK. Our 1st grader had a tour of the place where KIDDS is made (with a school group), up the road 40 miles or so from us. The coating that is on them is corn starch as is any starch that is in them (KIDDS brand and those packaged by them). I don't have a package or phone number here but they are on the bags. They were more than helpful with looking the information up then calling there lab to verify it. We have given them to our 2 year old celiac with no problems (I know this isn't scientific but...).
