Substituting Whole Wheat Flour in place of Flour

Baking S.O.S. says: Absolutely!The general rule when substituting wheat flour in a recipe is to use half whole wheat and half all-purpose flour.  If you try to use more than that (i.e. using all whole wheat flour), the texture and taste is completely altered. This is especially important when making cookies: you still want them to be tender and chewy. Using all whole wheat flour would make them more tough.

Good luck!
