I have a customer who wants me to do a cake and freeze it. Because she had to change the date for the shower. I am doing a buttercream sheet cake with gumpaste baby and flowers. I normally do my lettering in fondant with the tappits. My question is will the gumpaste and fondant be okay? I will deliver the cake on Thursday. The shower is Saturday.
Unless it's filled with something that requires refrigeration, your buttercream cake can stay out at room temperature for several days longer than the two days before it's served. Freezing isn't necessary.
Is the cake already done, not sure why you couldn't wait to make the cake. I think the cake would be fine to freeze, why not leave the gumpaste items off, and let her put them on herself.
