Somehow Texas claimed the sheet cake as its own in the mid-20th century, perhaps because of the pecans in the frosting, an ingredient that grows in abundance throughout the Lone Star State. The defining element is a large baking sheet or jelly-roll pan for baking . . . and the frosting, which has to be heated and poured on the cake while the cake is warm out of the oven. The result is a rich, chocolaty treat that’s synonomous with Texas.
