Preheat oven to 350 F. Lightly grease a 9x13-inch glass baking dish with non-stick cooking spray.
In a mixing bowl, make the spice mix cake batter as directed on the box. Stir in the canned pumpkin and then add about 1 cup of chocolate chips to the batter.
Pour the batter into the prepared baking dish. Add a few dollops of the no-bake cheesecake filling into the batter and use a knife to swirl it into the batter - in whatever pattern you prefer. Sprinkle the remaining chocolate chips on top of the batter.
Bake in the preheated oven for 25 to 28 minutes, or until a toothpick comes out clean in the center. Let cool slightly before slicing and serving.
Serve Pumpkin Chocolate Swirl Cake, as is, chilled, with a dollop of whipped cream or a small scoop of ice cream. Enjoy!
