Rich and decadent, from deep in the heart of Texas! This truly is the absolute BEST chocolate sheet cake I've ever eaten!! The frosting features Mexican Ibarra chocolate (which is flavored with almonds and cinnamon), Texas pecans, and whipping cream. YUM! Note: A sheetcake is a long and flat single layer cake. This is a very well written recipe, and is relatively easy to prepare--and even easier to enjoy! :) I like mine with a scoop of vanilla ice cream on the side. Courtesy Ladies Home Journal.
