Preheat oven to 350 degrees F. Line a 9×13 baking dish with parchment paper and set aside. In a large bowl, combine the butter, sugar, eggs, pumpkin and vanilla. Mix until creamy.
In a medium bowl, combine the flour, baking powder, baking soda, salt and cinnamon. Mix well and gradually add to butter-sugar mixture, stirring until combined. Spread batter evenly into prepared pan.
In a small bowl, combine the cream cheese and pumpkin pie spice. Mix well and drop in dollups on top of batter in pan. Using a butter knife, make swirls through the cream cheese.
Top with chocolate chips and bake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center comes out clean. Let cool for 10 minutes, cut into squares and serve!
