I've heard that Devil's food cake woorks well, too. I haven't tried it yet. I'm thinking of experimentiing with Kahlua or Bailey's Irish Cream in there somehow. I made some brownies from a recipe on the back of the box(krusteaz gluten free, i think) and it had a bailey's icing recipe suggestion for them. It was so good I've become obsessed with what else would possibly be good with some Bailey's.Small world... I'm making them brownies for my sons graduation next week but they are not called knock you naked....same ingredients though. I use a Devils food cake mix....they are fabulous!!
