Help! The air conditioning in my van is out and no possibility of fixing it before the weekend. I am transporting a 10 inch cake about 90 miles. It will be hot (95+). I would like to use buttercream covered in fondant with fondant/gumpaste flowers. A friend has suggested using dry ice to keep the cake cool. Has anyone tried this? I don't want the flowers to soften. I am not using any filling. The trip will take about 1 1/2 hours.
Put your fridge on the COLDEST setting and have the cake chilled overnight prior to leaving. I've not done it but I would try dry ice - keep flowers separate!! put them on when you get there! Better safe than sorry. I'd buy a box the cake would fit plus extra room for a dry ice pack and put the dry ice pack in the box with the cake. Good luck at least it is not a stacked wedding cake!
What an inconvenience! Find a cooler that will accommodate your cake box and make sure to insert ice packs. I've done this many times with no problem.
