Preheat the oven to 350°F. Spray a 9x5-inch loaf pan with cooking spray or line it with parchment paper.
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, nutmeg, and pumpkin pie spice. Set aside.
1 ¾ cups all-purpose flour, 1 ½ teaspoons pumpkin pie spice, ½ teaspoon ground nutmeg, ½ teaspoon baking soda, ½ teaspoon baking powder, ½ teaspoon kosher salt
In a large bowl, combine the oil, eggs, and sugar. Then add the pumpkin and mix until smooth.
½ cup vegetable oil, 2 large eggs, 1 ½ cups granulated sugar, 1 cup Libby's 100% pure pumpkin
Stir in half of the flour mixture into the wet ingredients and mix gently until just combined. Be careful not to overmix. Add half of the water and mix until combined. Next, add the remaining flour and water, mixing to combine in between.
⅓ cup water
Pour the batter into the prepared pan and bake for 60–70 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
Cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely.
