The brownie has been a recipe I've struggled with ever since I started baking. The previous brownies I've made have always been ok, as it is hard to go wrong with a chocolaty square, but I just never felt they were great (and I always sorta thought a box mix brownie was better). I spent a few years making everything but brownies, then decided recently that I needed to finally find a decent recipe - it just seemed pathetic that I could make homemade Samoas, but not brownies.
Note: the original recipe actually called for whole wheat flour, but I misread that and used bread flour by mistake. They came out great, and very (very) chewy. Since then I have also been making it with regular flour, and they are also delicious - still chewier than cakey, but not quite as hard on your jaw.
