Betsy, thanks for taking the time to put in the link. I've already tried and enjoyed one essentially the same as the one you noted. All of the scratch "Tunnel" recipes I have seen include that note about requiring nuts. However, one of my kids can't eat nuts, so I am hoping that the Dean recipe using canned frosting won't require nuts. If I remember correctly, the original recipe (which I think used a dry frosting mix that is no longer available) did not require nuts, tho I might be wrong.
