The easiest way to make chocolate cake is buy a box of mix from your local grocery store. Usually you only add vegetable oil or/and eggs, just follow the instructions on the back of the box. You can mix it up in a bowl and spread it into your baking pan. Leave it in the oven for the amount of time on the box and ta-da! you have chocolate cake. You can then spread your frosting on. Cut into serving slices and there you go.
