Note: You can make your own icing for the cake with Butter Frosting, or buy it at the store, and dye it for something Halloween-ish. Decorating with candy corns (as I did above) is very cute, and you can even put a fake spider on top or something. Incidentally the cake is very moist and good, but even with the whole teaspoon of green food coloring, it is not particularly GREEN. However, it is best to mention to any group eating it that it supposed to be that odd brown-green hue. Otherwise you may end up with someone who avoids the cake and thinks something is wrong with it--that actually happened to me (though that guy was kind of an idiot, and said he would wait to see if anyone died before tasting it despite the fact that I had a sign by it calling it "Green Man Cake").
