Preheat 325 degrees F. Spray a 9” x 13” rectangular cake pan with non-stick spray, line the bottom with parchment paper ,and spray again.Set aside.
In the bowl of an electric mixer, or using a hand mixer and mixing bowl, beat the sugars and eggs together on medium-high speed until light and fluffy, about 2 to 3 minutes. Add the oil and vanilla and beat on medium until combined, about 30 seconds. Add the pumpkin puree and mix until combined, about another 30 seconds.
In a medium bowl, whisk together the flour, baking powder, cinnamon, ground ginger, nutmeg, and salt. With the mixer on the lowest speed, gradually add to the pumpkin/egg mixture.
Pour the batter into the pan and bake until a knife or toothpick inserted into the center comes out with a few moist crumbs on it, about 33 to 37 minutes.
Let the cake cool completely before poking holes on the top. This can be done with a fork, straw, handle of a wooden spoon, or even chopsticks. Whatever you have on hand!
