Heat oven to 350 degrees. Prepare two 9x5-inch loaf pans by spraying with cooking spray. Set aside.
n a large bowl, combine the flour, sugar, baking soda, salt, cinnamon, nutmeg, and pumpkin pie spice. Stir with a wire whisk to break up clumps.
All ovens are different so keep an eye on the bread. Start at 55 minutes and go from there. A toothpick inserted into the middle of the bread should not come out with wet batter. It should come out with moist, dry crumbs. My bread took about 70 minutes to fully bake.
A 15 oz can of pumpkin is equal 2 cups minus 2 tablespoons. Sometimes all I have is a large can of pumpkin so I measure out 2 cups and take out 2 tablespoons (from the 2 cups), and then add it to the recipe.
