You can heat the buttercream and make a very nice icing (almost like glaze) for flooding cookies. I have done it and it works well and you would never know to look at it that it is buttercream. I use an all butter buttercream for this, and the taste is just like true buttercream. You do have to keep it warm for it to work well, but I've put it in bottles to use just like you would royal icing.
You can also add a lot of powdered sugar after heating and, if you're careful, roll it and cut it like rolled fondant, and that is insanely good and looks perfect -- without the greasiness of rolled fondant.
I have pictures of both ways, but they're not on the computer yet, so I haven't posted them.
