Preheat oven to 400 degrees. Flour and grease donut pans or coat with cooking spray.
Combine cake mix and pumpkin puree in a bowl or mixer until well blended. Stir in chocolate chips.
Fill disposable pastry bag with batter and cut a tip off the end so you have enough room to pipe a chocolate chip through the opening. Pipe batter into prepared donut pans.
Bake mini pan for 4-5 minutes, large pan for 7-8 minutes.
Let cool for 5 minutes, then place warm donuts in a paper bag filled with powdered sugar and shake well.
Enjoy with a hot cup of coffee!
