Preheat the oven to 350 degrees. Spray baking sheet with baking spray or line with parchment paper.
In a small saucepan heat the chocolate chips, cream, and butter over low heat stirring constantly until the chocolate is melted. Set aside to cool and thicken slightly.
In a medium bowl beat the cream cheese until smooth.
Add ¼ cup of the sugar and the vanilla. Beat on medium until smooth.
Add one egg and beat on low until just combined. Set aside.
In the large mixing bowl add the flour, the remaining sugar, the baking powder, the baking soda, cinnamon, and the salt. Whisk until combined.
In the medium bowl whisk to mix the pumpkin, the remaining egg, and the oil until smooth.
Add the pumpkin mixture to the flour mixture and whisk until smooth and the flour is all moistened. Pour the batter into the prepared pan.
Alternately spoon the cream cheese mixture and the chocolate mixture in dollops over the top of the pumpkin mixture in the pan.
Using a thin offset spatula or butter knife swirl through the batter slightly to marble.
Bake for 20-25 minutes or until set. If you used an 8"x8" pan you will need a bit more baking time and may need a foil tent over the top towards the end of the baking time to prevent over-browning.
Cool in the pan on a wire rack. When completely cooled and set cut into bars with a sharp knife. Store in the refrigerator.
