I am making a "pocket of aces" cake for a friend's brother. He will be traveling with the cake for 5 hours to get to the destination. I thought about using buttercream, but I don't know how well it would do in the car for that long, and I have to have it ready a couple of days ahead of time. Should I just stick with the idea of using fondant, which I planned to do? I think it will keep it moister, and help maintain the integrity of the cake. What do you think, fondant or buttercream?

u would still use bc under the fondant, it really wont make that much difference, if any. bc seals the cake in the same way as fondant. as long as the car is not hot it will b ok.

I am still going to use buttercream under the fonadant, but I was wondering if it would be okay, to only use buttercream. At this point I'm leaning towards the buttercream and fondant unless something/someone changes my mind.
