As I'm pretty new to cake baking (I've only just mastered the art of the basic sponge!) - Can someone please advise on the above; I've noticed a lot of cakes on here are RVC or part thereof, but having read the recipe for it, it seems to be quite a delicate cake, so can I assume it would not be suitable for covering with fondant and maybe being the bottom part of a layered/stacked cake? Thanks in advance.

I've covered it with fondant and used it in a stacked cake. Held up just fine!

I've used it for both (fondant and tiered) without a problem...usually a pretty moist cake, and of course very yummy!

RV was the cake I used for the first wedding cake I ever made. Never covered it in fondant, but there's no reason you couldn't. It's as sturdy as any other butter cake.

I've done it too. The recipe I used was a little soft but it held up perfectly fine.
