I did not modify this recipe...for once! And I loved how it turned out the way it is. It's very chocolatey, rich, almost fudge-like, and would wow any of your chocohalic-friends. I also made the entire batch using the exact measurement pan that Ina used (because we had two dinners to go to with friends); and this recipe made 20 LARGE brownies. It can easily be cut into 40-standard size brownies. The only "complaint" that I have, if at all, is that I must have used 5 different bowls when making this. A bowl for the chocolate to melt, a bowl for the walnuts and chocolate chips, a bowl for this.... but it was a very minor complaint in comparison to the reward of having this hunk of scrumptious brownies with coffee.
Another reason to love this recipe was that it retained its moisture if you wrap it tightly with a plastic wrap!!! We enjoyed this recipe for the whole week, and we loved it even better 2-3 days later. That's something that I don't normally find in baked goods!
