For some reason, it took me far to long to realize that you can freeze your leftover frosting. I would bake cakes and cupcakes and I would find myself frustrated with having a dab of this kind of frosting or a bit of that kind of frosting leftover.
I first read about freezing your leftover frosting from Rose Levy Beranbaum in her famous book, the Cake Bible. She recommends freezing your leftovers and eventually using them up to frost cupcakes.
How to freeze leftover frosting
Place your leftover frosting into a freezer safe container and pop it into the freezer. The next time you make some cupcakes or need a dab of a certain color, dig out all of your little containers of frosting.
These are the jars in the picture (affiliate link), but often I just use a freezer zip lock bag. You can also freeze in regular glass mason jars, just be sure to leave some headspace (an inch or two at the top) for freezing room. Otherwise the jar might burst.
How to thaw frozen frosting
Allow frozen frosting a couple of hours to come to room temperature. If the butter separates out, beat it for a couple of minutes. You can also microwave it at half power in bursts of 10 seconds. Be careful thawing this way, you can melt you butter and then you’ll have a soupy mess.
