Chocolate chip cookies with whole wheat flour
I made chocolate chunk cookies with whole wheat flour, sifted whole wheat flour and all purpose flour.

 
The picture didn't come out good, the cookies were thicker and lighter in color than what they look like here.

The cookie with whole wheat flour was denser and barely spread out while baking. It also had a very different "whole wheat" taste.

The one with sifted whole wheat flour was somewhere in between.

I won't be making whole wheat flour chocolate chip cookies (if the recipe calls for all purpose flour) again, but I won't mind the ones with sifted whole wheat flour.
