Preheat the oven to 350 degrees F. Lightly spray two 9" round cake pans and line the bottoms with parchment paper.
In a large bowl whisk the flour, baking soda, baking powder, salt, cinnamon, ginger, cardamom, allspice, set aside.
In another bowl combine the pumpkin, sugar, orange zest and vanilla and beat on medium speed with hand mixer until smooth.
Add the eggs, one at a time, beating until each one is incorporated. Slowly add in your vegetable oil.
Add the flour mixture and mix just until incorporated.
Divide the batter between your 2 pans and bake in the oven for about 30 minutes or until top springs back and a toothpick comes out clean.
Let cool in pans for about 10 minutes, then on a wire rack until completely cooled.
