Easy, moist Pumpkin Bread

3 1/2 cups all-purpose flour
2 teaspoons baking soda
1 teaspoon baking powder
3 teaspoons pumpkin pie spice
1 teaspoon salt
3 cups white sugar
1 cup vegetable oil
4 eggs
1 (15 ounce) can pumpkin puree
1/2 cup water


Preheat oven to 350 degrees F (175 degrees C). Grease two 9x5 inch loaf pans. Sift together the flour, baking soda, baking powder, salt, and pumpkin pie spice. Set aside.
In a large bowl, beat together sugar, oil, eggs, and pumpkin. Stir in flour mixture alternately with water. Divide batter evenly between the prepared pans.
Bake in the preheated oven for 60 to 70 minutes, or until a toothpick inserted into the center comes out clean. For best flavor, store wrapped in plastic wrap at room temperature for a full day before serving.
