Preheat the oven to 325°F
Grease a bundt pan (12 cup size) with cooking spray or butter
Sift flour, spices, baking powder, baking soda and salt into a medium bowl. Set aside
Add sugar, oil, and pumpkin to a bowl. Mix with a whisk until smooth
Add in the vanilla and eggs, one at a time, beating after each addition
Add in the flour mixture and mix until just combined (do not over mix at this step)
Pour the batter into the greased bundt pan and bake for 55 minutes - 1 hour 5 minutes or until a toothpick comes out clean
Allow the cake to cool for 10 minutes before removing it from the pan to cool completely on a wire rack (if the cake is not coming out, use a knife and gently run it along the edges being careful to loosen but not cut the cake)
