Yes. Remove 1 Tbsp. of whole grain flour per cup and add 1 Tbsp of liquid.
Substituting whole grain flour can substantially change the texture and taste of your recipe. You might first try substituting 1/3-1/2 of the total amount of white flour with whole wheat, just to be sure your recipe will work as desired. So if your recipe calls for 3 cups of flour, try using 2 cups white flour and 1 cup of Whole Wheat Graham or White Whole Wheat Flour.
