I've never tried that. This is using canned frosting, like Duncan Hines or Betty Crocker, and not a dry mix? My first reaction is it sounds kind of disgusting and too rich - I'd eat one bite and feel sick. (I'm just wondering and NOT trying to be critical.) Is it just frosting mixed with chocolate chips? How does it become fudgy?
Whoops, I guess I'm sort of going off topic, sorry....
