The Ultimate Buttermilk Brownie

I have found the ultimate brownie. It is perfection. Now leave me and this pan of goodness alone. Try your best not to over bake these. I know it can be a little tricky, what with different elevations and ovens do vary a bit. I always have to add about 10 minutes to a 9x13" pan of cake and 5 minutes to a pan of brownies. I forget the elevation of where I am at...but it is very high anyways. Trust your best judgment and try try try not to over bake. You might loose the all important fudginess factor if you do.
