Heat oven to 350 degrees F. Butter a 6-cup loaf pan or coat it with nonstick spray.
In a large bowl, whisk together pumpkin, oil, eggs and sugar until smooth.
Sprinkle baking powder, baking soda, salt, cinnamon, nutmeg, ginger and cloves over batter and whisk until well-combined.
Add flour and stir with a spoon, just until mixed.
Scrape into prepared pan and smooth the top.
In a small dish, or empty measuring cup, stir sugar and cinnamon together. Sprinkle over top of batter.
Bake bread for 65 to 75 minutes until a tester poked into all parts of cake comes out batter-free, turning the cake once during the baking time for even coloring.
You can cool it in the pan for 10 minutes and then remove it, or cool it completely in there.
