P.S. Brother says he's been using cream instead of butter for the glaze, because "What kind of bullshit are they making with chocolate chips and *butter*? That's not a *ganache*, that's basically icing but with less sugar."

Unlike Brother, I am not a cook and do not have a relevant sense of professional pride. But I like the glaze as he makes it and generally dislike icing, so I figure he's on to something.
