Preheat the oven to 350°F and line a baking sheet with parchment paper.

In a medium bowl, whisk together the cake mix and pumpkin pie spice. Mix in the pumpkin puree until fully combined.

Fold in the chopped pecans, if using. Use a 2 tablespoon cookie scoop to drop dough onto the prepared baking sheet, leaving about an inch between each cookie.

Bake for 11-13 minutes or until a toothpick inserted in the center comes out clean. Let cool completely on a wire rack.

Frost with vanilla frosting and sprinkle with additional pumpkin pie spice, if desired. Serve and enjoy!
