Texas Sesquincentennial Cake

Why I Love This Recipe
I am a Texas expat but still love and search out all things from home. I ran across this recipe and have yet to be able to try it out. If anyone has ever tried this cake I'd love to hear about it. I know this cake was made in honor of the birthday of my home state.
