Chocolate Mayonnaise Cake

My sister-in-law gave me a cookbook a couple years ago for Christmas and I found this one in there. It's super-easy and only has a few ingredients. And wow! it is soooooo moist and you don't even need icing on it! I just dust it with powdered sugar and it's good to go! I make mine with olive oil mayonnaise to cut some of the calories, but it's good so I use it for a quick sweet treat for the fam!
