how long does cake frosting last

[missingmyflatbelly]

I made some tonight from hummingbird book,I've never made it before so have no idea how long it can keep for and there was quite a bit leftover

In the fridge it'll keep for weeks

Oh cool thanks! They must put a lot of frosting on their cakes in hummingbird Because i made the suggested amount for the quantity of cakes and there was waay too much! I can keep it for the next batch now though ...

In my fridge it can last for, oh, minutes

I have frozen some, too.
