Chocolate Buttermilk Sheet Cake

My friend Steve at work loves chocolate and requested something yummy and chocolatey for his next shift.  So that is when my hunt for great chocolate recipes started.  I first found this recipe on Bake or Break that sounded great, which used this recipe from All Recipes that also had great reviews.  So I specifically went out to the grocery store to buy buttermilk to make this cake for Steve, but when I got home my internet was down again and I didn't write down the recipe from before hand.  So in my frustration I started searching my cookbooks for a yummy buttermilk chocolate cake and found one that appealed to me in my Better Homes and Garden cookbook. 

The cake turned out great (Steve was satisfied and my mission was accomplished) it was moist, chocolatey, and defintely yummy! I would definately make this cake again, or maybe even try the first recipe I found on Bake or Break and compare the two (even though they're very similar recipes).  I made a half version in an 8*8in pan for 35min @350F but im posted the orginal full version below so you can enjoy more cake!
