When out of whole wheat flour, I have used white flour in the called for amounts and it is very good also. Also, in place of all of the individual spices, I have used 1 TB of Pumpkin Pie spice and it works fine. If you can find them, Sugar Pie Pumpkins are the smoothest and most flavorful for baking. Also they are not stringy when baked. Or use canned plain pumpkin (not the pumpkin pie mix).
