Preheat oven to 350 degrees. Spray a 9 x 13 baking dish with non-stick cooking spray.
In a large bowl whisk together cake mix, eggs, pumpkin, milk, butter, sugar, and pumpkin spice until well combined.
Pour batter into prepared baking dish.
In a medium bowl beat the cream cheese and butter together using an electric hand mixer until smooth. Beat in powdered sugar 1/2 cup at a time until well incorporated.
Place spoonfuls of the mixture all over the top of the pumpkin batter. Using a knife swirl the pumpkin batter through the cream cheese mixture. Don't over swirl. Sprinkle the chips on top.
Place in preheated oven for 30-35 minutes until a toothpick inserted in the center of cake comes out clean. Allow cake to cool completely before serving. (Cake will be very moist.)
Looks delicious how about adding some Pecans also
Yes the pecans would add a nice crunch and flavor.
