Very disappointed. I followed the recipe with no changes, using all but about 50 grams of 70% dark chocolate, so the cookies were not too sweet, which I liked. I weigh all my ingredients (eliminating question whether to sift before or after measuring), so I know I used the correct amount of flour. The dough looked like cake batter, but firmed up nicely in the freezer and was not difficult to form into balls. However, my cookies were cakey, not crisp or chewy like a brownie should be, and they burned on the bottom at 10 minutes without ever cracking on the top. I would not make this recipe again.
10 Stars! Baking is science. Just make sure you follow the directions. Very chocolatey! Perfect treat.
