I have to drive an hour or maybe an hour and a half (if traffic) to deliver a buttercream cake in Florida's heat. The buttercream has no shortening, all butter. I will have AC in car but still worried. I was thinking of dry ice but never used it. If anyone has, can you give me some ideas how to go about this.
It will travel fine with the AC. Make sure it is out of any part of sunlight as the glass will intensify any heat and will discolor. I used dry ice once in the trunk, it is not worth the cost. Line the complete area where the cake will be for a sanitary area. I used disposable plastic table cloths for that.
OH! use something like rubberized drawer liner, cut to size, for the cake to sit on so it does not slide! Make sure the cake is level, if it is on the seat use a stabilizing board... oohhhhh through the mistakes Ive learned..........lol
