I need to have a cake ready for tomorrow morning at 9 am. So, I want to prepare the cake tonight. The problem is that its a HUGE cake so it wont fit in my fridge. Therefore I would have to keep it outside in an aircondition room. Will my buttercream spoil if its kept in an aircondition room? Or does it have to go in the fridge?
Please help, otherwise I would have wake up very earlier to finish the cake and that makes me very nervous!
Even if it had real butter in it, it should be able to sit out in a cool dry area. Won't spoil overnight for sure.
your buttercream will be fine over night.
your bigger concerns are:
does the FILLING need to be refrigerated (if using BC - no)
keeping prying hands and PAWS away from the cake (kids, husbands, pets)
and beware ants, etc if that's a local problem. (they seem drawn to the fat/sugar combo)
I don't refridgerator my cakes once iced, I usually keep them in a cake box in an A/Ced room. You'd only need to refridgerate if using perishable fillings.
thank you everyone for you help. BTW, its made with butter and heavy cream. Does that make a difference?
It doesn't make a difference: what type of filling do have?
just using buttercream, no filling
The amount of powder sugar in buttercream acts as a preservative and the small amounts of dairy in it will be fine.
Thank you everyone!
