What flour is best for baking cookies?
What flour is best for baking cookies depends on the type of cookies you want. Flours have different protein contents that will affect the amount of liquid absorbed and the texture/tenderness of your cookies. Lower protein flours will such as cake flour and bleached all-purpose flour result in more tender cookies; higher protein flours such as unbleached all-purpose flour and bread flour will produce thick and chewy cookies. I prefer King Arthur unbleached all-purpose flour for most of my homemade cookie making and baking, since I tend to prefer thicker, more chewy old-fashioned drop cookies.
