I tried this recipe twice. Did not turn out either time. The first time, all the butter rose to the top and just sat there until I took the brownies out after 30 minutes. They seemed overcooked, but I guess I left them in too long to see if the butter would evaporate, instead of floating on top. Yuck.
The second time, the butter did not separate, but after 30 minutes, they were still too dry and I was afraid to shorten the baking time.
This was a waste of a package of Baker's bitter chocolate! Very disappointing
