I have found that if you prepare the devil's food cake as directed, then poke holes all over, about 1.5" apart with the handle of a wooden spoon, the smear some holes with vanilla and some with chocolate (no need to get anal and make them alternating, too time consuming), then frost with a mix of powdered sugar, butter, about a tsp of dark chocolate Hershey's baking cocoa, and the homemade Kahlua to the right consistency....oh man, so good!
