Preheat your oven to what the box of brownie mix states.
Make the brownie mix in a mixing bowl, using the ingredients called for on the box and the box instructions. Mix in the chocolate chips.
In another mixing bowl, add the cream cheese, pumpkin, sugar, and pumpkin pie spice. Use an electric mixer to mix until smooth and well blended.
Use an electric mixer to mix until smooth and very well blended. Don't let the spoon fool you, I used that to clean down the side of the bowl, you will need an electric mixer for this.
For the baking pan, depends on what the brownie mix recommends, 9x13 or 8x8 inches seem fairly standard, but do make a note of the baking time for the size pan you use. Grease the pan with butter or cooking spray.
Pour half the brownie batter into the prepared pan and spread out evenly.
Add the pumpkin to the pan, spreading evenly over the brownie batter.
Add the remaining brownie batter to the pan, spreading evenly over the pumpkin.
Bake the brownies, adding 10 minutes to the time stated on the brownie box instructions, this is due to increased thickness. To check for doneness, insert a fork in the center and if it comes out clean, it is done, if there is batter on the tines, continue baking, checking every 5-8 minutes until done. The fork method for testing works perfectly!
Let brownies cool completely, cut into squares, serve, and enjoy.
