I used a carrot cake mix because I didn't want to put all the effort into a cake from scratch that might not turn out. I mixed it according to the directions on the package, then poured it into the greased crockpot. I turned it on high, and waited two hours. I think it might have been done closer to an hour and a half, but I was afraid to open the lid! As it was, I cut about 1/4 inch of slightly toasted (not even burnt!) edge off one side. It was delicious plain, with ice-cream, and with frosting! Oh, yeah!
