Preheat oven to 325 degrees F. Line a 9x13 inch pan with parchment paper.
In a large bowl, whisk together flour, baking powder, baking soda, ground cinnamon, ginger, cloves and salt. Set aside.
In a mixing bowl beat the eggs and sugar until smooth. Next beat in the oil, vanilla and pumpkin. Slowly mix add in your flour mixture and beat until incorporated. Stir in chocolate chips. Evenly pour the batter into the lined cake pan.
Bake for 33-36 minutes or until a toothpick comes out clean and the top is golden brown. Transfer your giant cookie, still attached to the parchment paper, to a wire rack to cool. When cooled completely cut into squares.
