My youngest has a peanut allergy and I have discovered cookies from "Enjoy Life" which caters to people with food allergies.  All of their items are made in a nut free factory.  My oldest does not have a food allergy but she also liked the cookies, especially the chocolate chip ones.  A bit pricey but at least I found cookies that will please everyone.  I have not tried any of the other items yet but I am sure they are just as good.  So if you are still on the hunt for yummy treats for your child with food allergies, try this brand.
