For chocolate and a good stout recipe, start with the founders kbs/breakfast clones released by the brewers. Basically its baking chocolate and also, I use powdered chocolate with 10 minutes left or so in boil. There is a thread here with more. For coffee put it in at kegging and rack beer onto it. I love chocolate flavor and next time I am going to add a lot more powder. The recipe calls for cocoa nibs. Cacao is different and unless you know you love it, it might not be the right flavor. Cocoa and probably even quality dutch processed is what you need.
