So, I am ridiculously pleased with myself for having made DS a birthday cake for tomorrow, but being a total cake novice I'm not sure about storage?
I didn't bake it myself, as such, as it's a 'no-bake' cake using premade cakes to form a train (inspired by that bloody Annabel K woman, but creativity entirely my own ) but I did make my own buttercream, which is the bit I'm not sure about.
Basically it's a load of chopped up loaf cakes completely covered in buttercream icing and topped with sweets/biscuits etc - do I need to refrigerate or can I just loosely cover in tin foil and leave it out?
