I am making a wedding cake in a couple of weeks. I am just a hobbyist, and the cake is for a friend's son. I know that wilton icing is an option, and I have made IMBC and SMBC before. I love the meringue icings, but we live in VA and the wedding will be outside. It's across the street. I don't plan on taking the cake over until after the ceremony is over. I wasn't sure what kind of icing will be best. I would love to do a meringue, but I don't want my cake to melt apart either ! The wedding is september 19th, so it will still be upper 70s or so here....

Any help will be appreciated. Glad I'm such a planner so I can test this out !!

I have been told that IMBC can withstand outdoor heat and humidity for up to four hours. Haven't tried that yet myself but this info was found in a very well known cake artist's book. Also Bettercreme is a non dairy frosting that does not require refrig and although it is alot like a whipped cream frosting (tastes like soft serve ice cream) it holds its own. I have used that for many outdoor events.hth
