Do you use the same amount of bread flour as all-purpose flour in cookie recipes?
Yes. Pretty much. The difference in the two flours is the ability to form gluten. Bread flour is ground from a different variety of wheat, and produces more gluten when kneaded and so is of greater value when making bread. As you do not knead cookie dough, it doesn't come into play, and for the the most part cookie recipes are not that critical. Do not use bread flour for making cakes when cake flour is called for. Cakes are different animals altogether and proper ingredients are critical, and you cannot substitute a hard wheat flour for the soft cake flour, (which produces almost no gluten.)
