Ok I am heading into a huge week of cakes on the 23rd thru 28th. 
And want to as much before that I can. I have great nephews 1st B-Day cake, Nieces B-Day cake and some cupcakes for her class, And DD haunted castle cake along with the cakes for her cake decorating party. So I want to make and freeze the buttercream. I will be using the basic wilton version with a twist. For the double recipe I use 1/2 cup butter and 1 1/2 cups crisco. First will this freeze well? Second should I freeze in freezer bags put in containers and place in freezer?? Can it be refrozen on the cake then??? Any help would be greatly appreciated. With all the things I have going on craft shows. Sons physical therapy for his knees, I want to get as much done ahead of time as possible. 
Yep, you can freeze it! I freeze it all the time. As a matter of fact I just took some out of the freezer for tomorrow. I take it out & put it in the refrigerator & keep it there till I use it~ I use the gallon icecream buckets, they work great. Also any container but you can also freeze it in ziploc bags.
I don't know about freezing a cake that is iced, I've never done it. But I do freeze a crumb coated cake. It thaws out nicely~ Just keep it wrapped till it's thawed~ Keeps the moisture in.
Good luck with all your cakes! Your going to be a busy little baker this week!
TC thanks for your help That is what I was thinking. Maybe I will do the 1st B-Day cake and then freeze it. It is only a sheet cake with a small smash cake. Then freeze the icing after them for the others. I totally thank you If anyone else knows about the freezing again after frosting cake with prefrozen icing let me know. Thanks
Glad I could help! I'm filling buckets with BC right now to freeze!
I'm sure someone will see this post & be able to help you out more~ Have a great day~
