Preheat your oven to 350. Grease a 9×13 pan and set aside.
In a large mixing bowl, whisk together the spice cake mix, sugar, and pumpkin pie spice. Once the dry ingredients are fully incorporated, add in all of the wet ingredients (eggs, pumpkin, water, and oil). Mix well until all ingredients are combined and there are no dry ingredients visible. Pour cake batter into the greased 9×13 pan and set aside.
In a separate bowl, use a hand mixer to combine the cream cheese and butter. They should be mixed until creamy and completely combined. Slowly add in powdered sugar 1 cup at a time. The cream cheese mixture will be thick.
Place spoonfuls of the cream cheese filling over the top of the cake batter. Use a knife to swirl in the cream cheese. It will mix slightly into the cake batter and that’s totally fine. Sprinkle the top with the chocolate chips.
Bake for 35-40 minutes or until the center is not jiggly and the sides start to pull away from the pan.
