In a large mixing bowl, whisk together your flour, cocoa powder, baking soda, salt, cinnamon, nutmeg and chocolate chips (basically, all your dry ingredients).
In a second mixing bowl, whisk together your pumpkin, honey, molasses, egg, egg whites and vanilla (basically, all your wet ingredients).
Now, blend the dry mixture into the wet mixture, a little at a time.
Pour the batter into an oiled loaf pan and bake for about 40 minutes or until a cake tester (like a toothpick) comes out clean when you stick it in the middle. If you have to bake it longer than 40 minutes, loosely place a piece of foil over the top so the top doesn't burn. Check every 10 minutes until done.
