Preheat oven to 350 degrees. Prepare three 6" cake pans.
In a medium bowl, mix together the flour, baking powder, baking soda, salt, cinnamon, ginger, and nutmeg. Set aside.
Using the whish attachment of your mixer, mix together the vegetable oil, eggs, both sugars, pumpkin and vanilla until well combined.
With the mixer on low speed, slowly add the dry ingredients to the wet ingredients and mix until combined.
Divide the batter between the three prepared pans and bake for approximately 40 minutes or until a toothpick comes out with just a few crumbs. Ovens vary so time may differ.
