Add sugar and cinnamon to a bowl and whisk together to combine. Set aside.
Make the loaf batter
Preheat oven to 350°F degrees.
In a large bowl, whisk together the dry ingredients (flour, both sugars, baking soda, baking powder, cinnamon, nutmeg) until well blended.
Adding one at a time, whisk in the the pumpkin puree, eggs, vegetable oil, water, and vanilla to the dry mix, stirring in between each new ingredient.
Fold in the ½ cup chocolate chips last, until well blended.
Pour evenly into the prepared loaf pan.
Sprinkle remaining chocolate chips over the top of the loaf, and then sprinkle the cinnamon sugar mix evenly over the top of loaves. NOTE: only sprinkle on as much or as little cinnamon sugar as you like. Save the rest for another recipe.
Bake at 350°F degrees for 50-60 minutes, or until a toothpick inserted into the center of the loaf comes out clean without any wet batter.
