I made cream cheese frosting this past Wednesday. I put it in a rubbermaid air tight container in the fridge. I was wondering if this could last until Christmas or not. Thanks.

I would freeze it...or else it might get that stale smell and after taste.

do you know what the expiration date on the cream cheese was? if you don't then definately freeze it, but I would guess it would be good in the fridge as long as the cc was good.
