Can you freeze buttercream icing?

Yes, I have frozen my leftover BC. No problem, place in freezable container & to use,  just let it thaw up & stir well.

100%.  I always make my buttercream up in advance and put it in the freezer.  The night before I need it I put it in the fridge and then pull it out a couple hours to let it warm up to room temp and give it a quick stir.

Another one who agrees with what has been said:) 

Thank you everyone! I currently have it in a plastic ziploc storage bowl is that ok to put in the freezer like that or what kind of bowl?

 i’m different but still so loveable — I freeze my just baked cakes torted and filled — but I only make enough icing to get that all done — then I make fresh when it’s time to ice and decorate — because I think it holds the vanilla better — it makes a difference to me — I still had to hold the cake for a day or two before it’s eaten but the aromatherapy of the butter and vanilla wafting around my cake tables was always appreciated — if I did freeze icing I didn’t use it to cover a cake that I sold —

I once got to eat fresh made chocolate bonbons— then I ate some over the next days and while they were always incredibly delicious — hand made in person by a famous pastry chef — I was shocked at the loss of flavor — the first day they were astronomical, the second day they were seriously great — the following day they still beat Russell stover and anything you can buy at the store but they actually tasted completely different than the original product — 

If I have a good amount of frosting left over, I freeze it, just as previously stated.  It never occurred to me that it could loose flavor!  I will keep that in mind and add extra vanilla/almond if needed.

I always make fresh BC for each cake ordered but freeze any leftover BC to make my flowers with.
