Preheat oven to 350°F (175°C). Stir together cake mix and pumpkin puree in a large bowl until smooth, about 1 minute. Fold in chocolate chips.

Drop rounded tablespoonfuls of dough onto parchment-lined baking sheets, spaced 2 inches apart. Bake 10 to 12 minutes, until edges are set and tops look dry.

Let cookies cool on the sheet for 5 minutes, then transfer to a wire rack. Serve warm for the best melty chocolate.
