Buttercream Icing

I tried this buttercream icing on my Chocolate Crazy Cake (EF, DF) today.  I like it.  In the past, I had tried an all butter icing but it tested like sweet butter.  This recipe recommends mixing half butter and half shortening.  I was less buttery, which brought out more of the vanilla flavoring.
