jelly & chocolate crispy cakes - can I make these tomorrow to eat on Sun (separately..)

[funnyhaha]

they won't go off, will they? Although i was planning real (tinned) fruit in the jelly...still OK?

TIA

yes, will be fine
leave jelly in mould in fridge and turn out at last moment

keep crispies in airtight tin hidden from dh

dh away at a conference, so I'll have to hide them from myself...

& thanks
