Preheat the oven to 350°F/180°C/Gas 4. Spray a 9"x13" baking dish with nonstick baking spray and set it aside.

Place the cake mix, pumpkin, eggs, water, canola oil, and pumpkin pie spice into a mixing bowl and beat until combined and smooth. Set it aside.

Place the cream cheese, butter, and powdered sugar into another bowl and beat until combined and smooth. Set it aside.

Pour half of the pumpkin cake batter into the baking dish.

Use half of the cream cheese mixture and scoop spoonfuls onto the batter. Use a knife or skewer to swirl it around.

Pour the remaining pumpkin cake batter on top, followed by the remaining cream cheese mixture, and swirl around.

Sprinkle chocolate chips on top.

Bake in the preheated oven for 50-60 minutes or until an inserted toothpick comes out clean. (A few crumbs on the toothpick are fine!)

Allow the cake to cool completely before cutting and serving. Enjoy!
