First recipe tested was Hershey's Perfect Chocolate Cake with Hershey's Perfect Chocolate Frosting, recipe found on every can of Hershey's Natural Unsweetened Cocoa Powder. The cake was too sweet but moist and fluffy. The frosting not perfect at all.
Second was Nigella Lawson's Old Fashioned Chocolate Cake, recipe found on the internet via the Food Network with how-to video on youtube. Again the cake was too sweet, crumbly and dry. The frosting was a disaster. But I take full responsibility for the disaster through no fault of the author.
Third was Dorie Greenspan's Devil's Food White-Out Cake, recipe found on page 247 of her book "Baking". The cake was bland and dense, again probably my fault, but the icing was very good. Dad even helped me scuplt the design.
Finally, my very own Chocolate Madness Cake. The cake was a modified Hershey's Perfect Chocolate Cake recipe with Dorie Greenspan's version of 7-Minute Frosting. Success!
