Leftover Buttercream

So I made some buttercream frosting last night and I ended up with way more than I needed. I didn't want to a. eat all the buttercream, or b. waste it, so I did a little google search about what to do with leftover frosting. A very wise person said that you should make buttercream truffles, click here to get the play by play on how to make them. Oh my, I thought, what a good idea. So I did it and the truffles turned out great.
