Pinata cake help please.

[Scotty]

Last time I made a pinata cake the sweets went soft and lost their colour.
What sweets are best and is there any way to avoid it happening? Lining the void with chocolate perhaps?

Thanks

I’m not sure? I’ve not had that happen. What sweets did you use? I do mask the void with ganache or buttercream (very thinly) to stop the cake going stale then refrigerate briefly before filling.

Hi, I used smarties and something else. I used buttercream on the void. I'll see if I can find the pictures.
