About
While this sheet cake is Texan in name, it actually derives from a German. Well, not a resident or native of the European country, but an American named Sam German who invented the type of baking chocolate used in the original Texas Sheet Cake recipe. Once the recipe was published in the Dallas Morning News in 1957, it swept the country with its rich, buttery taste and impressive size — this cake alone feeds 32! And with a baking time of 30 minutes, you can whip it up in a flash. Texas Sheet Cake is a chocolatey, creamy potluck favorite... just make sure you save a slice for yourself.
