Is it necessary to refrigerate a cake with chocolate ganache filling? I would assume so, since it's basically whipping cream and chocolate, right? Thanks!

I am sure I heard it can be room temperture to because of the sugar in the chocolate... when I searched ganache on internet I found this little blurb to make me think it doesnt have to be.

"If cooled to room temperature it becomes a spreadable filling and frosting. Refrigerated ganache can be whipped for fillings and frostings or formed into truffles."

great, thanks!!

Ganache is "safe" at room temp, but whipped ganache can get quite soft if the room is very warm. If it is a heavy layer, watch out for the filling to soften. I haven't had any problems with the individual cakes I fill and keep and room temp.
