I found a message posted on this site from 2005 which mentioned a recipe for Blue Smoke's Chocolate Cake that was published in Bon Appetit, probably in April 1994. The poster was looking for the directions for making the frosting. My husband absolutely loves this cake, and his birthday is coming up. I've looked high and low for the recipe (no luck on epicurious.com) but can find no other reference to it.
If anyone has the old issue of Bon Appetit and can post the recipe, I would be very grateful!
