Can I? I made this recipe: [url] http://cakecentral.com/recipe/buttercream-frosting[/url]

I made it on Wednesday, and while I was decorating it was brought out and sat out for a while, before returning to the fridge. I have a TON left over, enough to do another 8 or 9" cake. I hate to just throw it away, but I won't do another cake until April probably.

Is there a "rule" for freezing buttercream? (for example: If it's under a week old it's safe to freeze???)

Thank you!

The link to the recipe does not work.
Generally, if it is a Crisco &/or butter, powdered sugar and liquid recipe it will freeze just fine. I suggest putting it in a couple of smaller containers so you don't continue to take it out, use some and put the rest back.

I have no idea if IMBC or SMBC can be frozen.

Sorry, here is the link. http://cakecentral.com/recipe/buttercream-frosting

I was just going to put it all in a ziplock freezer bag. I didn't know about how long I'd had it in the fridge already and the fact the recipe used whipping cream.[/url]

That recipe should be fine. The amount of powdered sugar acts as a preservative so the whipping cream shouldn't be a problem.
