Preheat the oven to 350°F. Spray two 9x5 inch loaf pans with nonstick spray.
In a medium bowl, whisk together the dry ingredients through spices.
In a large bowl, whisk together the pumpkin and remaining ingredients. Gently stir in the dry ingredients just until the dry mixture is incorporated (don't over mix).
Divide the batter evenly between the two prepared pans. Bake 55 to 65 minutes, or until a wooden pick inserted in center comes out clean. Cool the pans on wire racks for 20 minutes, and then gently turn out the loaves onto wire racks to cool completely.
