What kind of frosting do you glaze over your brownies?

[Diane Lane]

I make moist chewy brownies, so I don't frost them. I have in the past though, made cake-like brownies, and on those, I've put vanilla buttercream frosting or cream cheese frosting, and all versions are popular. My family is full of chocoholics, so for them, I have put fudgy chocolate frosting.
