Texas Chocolate Cake

Why I Love This Recipe
I have made a couple of versions of this cake and this one is by far my favorite. I don't remember who posted it on TOH. It is easy to do and very moist. The taste is heavenly.
As far as I am concerned, this is the worlds best cake. Make the holes tiny, or else you have ugly holes showing after the frosting hardens. BUT it is so good regardless.
