brownies from chocolate butter

I went to supercook.com and found a brownie recipe that looked like it would work.  I put in a bunch of normal baking type ingredients and then highlighted the chocolate and butter.  

I baked them tonight and they are good, but they don't really look like the picture - mine seem to be more cakelike than the photo.  Of course its hard to know if I really got the cream all the way to butter - and how to know when measuring out chocolate butter if you are getting the right amount of butter or not.  But it worked and we have something tasty out of it.  I still have some more of it left - I guess I need to measure how much chocolate butter I have and then do something with it.
