Spray a standard 9x5 inch loaf pan with nonstick baking spray and line with a parchment paper sling.
In the bowl of a stand mixer, or using a large bowl and whisk, briefly whisk together all dry ingredients.
Add to the bowl the pumpkin, oil, and coconut sugar and mix to combine so there are no flour streaks visible.
Add the eggs and whisk for 10 seconds more to combine.
Transfer the batter to the prepared pan and smooth the top.
Using a sharp knife, make a 1 inch slit down the length of the bread. This is optional, but it makes for a bakery-style loaf with a slit down the middle.
Sprinkle the top with dermera sugar, if desired.
Bake for 55-60 minutes until a tester comes out clean.
Cool for 10 minutes in the pan before transferring to a rack to cool completely.
