No one has mentioned these for some time here. It's worth a repeat.
Truth be known my firstborn is almost entirely constructed from brownies. Almost every day of the pregnancy I made a batch of brownies, (must have been an iron deficiency). Wish I had known about this recipe then, it's a recent discovery for me.
From what I've read the original recipe called for 2- 1 oz. squares of unsweetened chocolate instead of the cocoa used in the NYT recipe. In the interest of science I made both recipes and preferred the one with the unsweetened squares, but could only eat one at a sitting. Much more decadent. They are both very good.
Have you tried these? What is your preference?
