I have used black cocoa powder in my devil's food cakes and in a type of chocolate glaze that I make. I purchased it from Barry Callebaut directly. The only thing is that I had to get a 50 pound bag. The flavor is quite good, but people are sometimes put off by the color because they have never seen a black chocolate glaze. If you want some in depth information about the breakdown of the product itself, let me know and I'll se if I can dig up the specs they sent me.
