I have some pink buttercream in the freezer if I make it into red can I re-freeze it for a fbct?
also how long can a fbct be frozen for before use? I am making a hamburger cake for m dh's cousin if he comes up next weekend. I would have enough red (from the pink in the freezer) to make my fbct also but my ds's b-day isn't until the end of December.
I used the bc recipie in the Cake Mix Doctor book, it has been in the freezer about a month.

Absolutely - I use and freeze and use and freeze all the time. I rapidly learned that it was easier and less messy to make a couple of BIG batches once in awhile and freeze, than to make small batches every time I bake.

As to the FBCT - theoretically you can freeze it indefinitely. Realistically - do you want a single sheet of wax paper with buttercream on it taking up space in your freezer uncovered? I can't sacrifice that much freezer space for that long-I froze mine overnight.

Once it's frozen solid you can wrap the fbct and the board that it's on in plastic wrap and then foil. I've done this and kept it for over a month and didn't notice any difference in the taste of the buttercream used on the fbct!!! I made a practice fbct a month early and it turned out better than the 3 I tried the night before! lol

Thanks, I think I will make try it this week while dh is hunting, and dd is in school. So far dh's cousin hasn't been able to get off work, but I still intend to make him that cake eventually.
