Dessert-Buttermilk Brownie Cake

This recipe was in the newspaper and I just had to clip it because there is just something about brownies that I can't resist. Now, I am on a diet and have shed 20 pounds since last June so desserts are all I ever seem to notice. Maybe you can cook it and post a comment about what you think. The person posting this recipe said that it has been a family favorite for five generations and was a favorite at all their gatherings. Must be good!
