Sticking with blends that are still in production, the current incarnation of Three Nuns is actually pretty close. The top note is honey instead of vanilla, but it's the same sort of coin cut Virginia and Dark Fired Kentucky blend with that distinctive slightly sweet Mac Baren casing. If you like Vanilla Roll Cake then I think you'd enjoy Three Nuns very much, and mixing in a pinch of Mac Baren Vanilla Cream Loose Cut with a couple rubbed out coins of Three Nuns will get you pretty darn close to Vanilla Roll Cake, but you may find that you like Three Nuns just fine on it's own.
