I’m probably supposed to tell you that cream cheese frosting made with powdered sugar is fine. But you see I’ve been making a different kind of cream cheese frosting for a few years now, and the truth of the matter is that I can never go back. For those reasons and more, a few years ago I started making cream cheese ermine, which is fluffy, slightly tangy, and just sweet enough. It has a texture somewhere between the rich cream cheese frosting you know and pillowy whipped cream. Ermine frosting is an old-school style of frosting.
