You know that slice-and-bake cookie dough? I love it raw!! I also love cake batter, but I try not to eat it 'cause it has raw eggs in it.
I used to love Sara Lee banana cake, but haven't found it in years. For some reason the craft service trucks on movie and TV sets have it, though. Visited a friend of mine who was working on a TV set and had Sara Lee banana cake, first time in years! The frosting is to die for.
I found this recipe for a substitute you might like:
