Preheat oven to 350 degrees. Grease a 9x5 loaf pan with cooking spray or vegetable oil.
In a large bowl, whisk together the pumpkin pie filling, oil, sugar, molasses and vanilla.
In a seperate bowl mix together the flour, baking powder, baking soda, salt, cinnamon, nutmeg, cloves and ginger.
Slowly stir the flour mixture into the wet mixture until fully incorporated and no flour remains visible. Pour batter into prepareed loaf pan, using a spatula to scrape the bowl. Smooth the top.
Bake for 50-55 minutes, until cake tester comes out clean. (Glass loaf pans will cook faster). Transfer loaf pan to wire rack and let rest 10-15 minutes. Loosen the bread from the pan with a knife around the edges , then invert loaf onto a cutting board. Serve warm or cool.
