Preheat your oven to 350°F and grease two loaf pans generously with cooking spray or butter. Line the bottoms with parchment paper for easy removal, which prevents sticking and ensures clean presentation for your fall entertaining spread.
In a medium bowl, whisk together all-purpose flour, baking soda, baking powder, cinnamon, ginger, cloves, nutmeg, and salt. Set this dry mixture aside—it's the foundation for consistent texture throughout both loaves.
In a large bowl, combine granulated sugar, pumpkin puree, vegetable oil, eggs, and water using an electric mixer on medium speed for about two minutes. The mixture should look pale and slightly fluffy, indicating the eggs have been properly incorporated.
Gently fold the dry ingredients into the wet mixture using a rubber spatula or wooden spoon, stirring just until combined. This fall pumpkin bread crowd pleaser requires careful folding to avoid overmixing, which would develop gluten and create a dense, tough crumb instead of the tender texture that makes it disappear fast.
Fold in chopped walnuts and raisins until evenly distributed throughout the batter. Divide the mixture equally between your two prepared loaf pans, smoothing the tops with a spatula.
Bake for 55 to 60 minutes, until a toothpick inserted into the center comes out clean or with just a few moist crumbs. Don't overbake—the bread continues cooking slightly as it cools, and you want it tender and moist.
Remove from the oven and allow the loaves to cool in their pans for 15 minutes before turning them out onto wire racks. Complete cooling ensures the bread sets properly and slices cleanly.
