Ok UPDATE!!!!! I let the cake sit overnight and tasted it again and it was Delicious!!! Sooooooo much better... So on that note I changed my rationg from 3 stars to 5! I am a true believer that you can make a delicious chockolate cake with mayonnaise lol I thought this cake was just ok...Not a bad recipe but certainly not one one that Id make again anytime soon.It does bake up fluffy and moist but it definitely is Not sweet enough so it really needs 1/2 cup more sugar. I felt like it wasnt chocolatly enough just my own personal preference.if your looking for a fast and very few ingredient chocolate cake then this recipe is Perfect!!
