I made a cake last night and this first choc. cake fizzled-I don't think I had enough batter in the pan, but it was 1/2 full. Of course, I didn't have another choc mix, but did have a yellow one. So I added a choc inst. pudding (dry) and 4 squares of melted semi sweet choc. It baked up nice-not devils food by any means, but better than nothing! I am wondering if there is a standard way to convert a white/yellow mix to choc-what has anyone else done?? Thanks!!

Yes, it has been done. Check the recipes section.
