These are the "perfect" brownies. fudgy, super chocolatey, and just a little chewy (despite the title they are not overly chewy, but just right) I love these. I usually check them before the lowest cooking time given, they are done in my oven by about 30 min. Source:Fine Cooking Magazine. Notes: (from the recipe) This recipe can be doubled easily; use a 13X9-inch pan and increase the baking time slightly. The recipe gives a range of baking times -- use the shorter time for metal pans, the longer for Pyrex pans.
