This is one of my favorite chocolate cake recipes. It is made with Guinness beer (learn more about this beer at http://www.guinness.com/), which gives the cake a nice rich, dense, chocolate taste. I made it for my girlfriends birthday in the summer and it seemed to be very popular. There are many different versions of this cake but you can find the recipe that I used at http://www.cookiemadness.net/?p=1388, which is my favorite version of this cake. I decorated my cake with little toffee bits which gave it a more sweet taste to go along with the frosting.
