Choc Biscuit Cake - how long in fridge?

[Lickitysplit]

I made a chocolate biscuit cake with rich tea biscuits and mini marshmallows, how many days should this keep for? Made it last night and hoping to serve it at a party on Saturday?

my god! you mean you have to worry how long it'll keep??? this stuff is so yummy it disappears the same day with my kids! seriously though in an air tight container i would have thought a couple of days would be fine.

I made one on Saturday and the last piece went last night while I was at the pub......and I was looking forward to it when I got back!!!
