One of my favorite cakes in the whole world is a Texas Sheath Cake. I bake it in a jelly roll pan or as a 9 x 13 cake. The light touch of cinnamon in the chocolate cake makes the taste supreme. If you want that flavor but don't have the time to make it from scratch, here is a easy way to get the same flavor:
Buy Duncan Hines Swiss Chocolate Cake Mix (do not substitue the Swiss chocolate mix as it is the only one that has a similar taste to the Texas Sheath Cake) and mix per the directions on the box.
