I'm having an issue...I'm making a cake with chocolate ganache filling, and I'm sure it won't be wise to leave it out. My problem is that it will be covered in total black fondant & I can not take a chance with wet spots or other condensation issues.
I've heard that putting the cake in a cardboard box, not cake box, will keep cake refrigerated without damaging the cake.
I appreciate any help with this because I don't want to mess my cake up, but I don't want the filling to go bad. Also, will refrigerating the cake make it stale? thanks again for any help!!!!

I ganache cakes all the time and Never refrigerate them because I want the layer to dry and set up before I put the fondant on. I just cover it with my cake cover so it doesn't get dust on it. I usually bake on Tuesday, ganache on Wed Thurs depending on how much or type of decoration, fondant on thurs Fri and decorate.

I never refrigerate in between and I have never had a cake go bad or off.

I've left ganache out for days, and it's fine.
