AHi there. I'm making a topper for a friend's cake and it will be moulded from RCTs and covered in fondant or modelling chocolate (yet to decide). How far in advance can I make it? I'd hate for the insides to spoil, but at the same time I'm thinking that if it's sealed in the outer coating it would be somewhat protected. Thoughts? Thanks.
They can be done far in advance, I suppose the RCT may get stale, but not 'spoil', but the outer layer will seal it so it will last weeks.
