Preheat oven to 350°F. Grease a cake pop or donut hole mold with nonstick spray.
In a large mixing bowl, combine dry cake mix, pumpkin puree, brown sugar, and pumpkin pie spice. Mix with a stand mixer or hand mixer on medium speed, scraping the sides of the bowl halfway through.
Fill a piping bag or zip-top bag with the batter. Snip a ½-inch opening and pipe batter into the mold cavities.
Bake for 15-20 minutes, or until a toothpick inserted into the vent hole of the mold comes out clean. Leave the top mold in place until the donut holes have cooled.
Transfer donut holes to a wire rack and let cool for 5 minutes.
Melt butter in a microwave-safe bowl. In a separate bowl, mix sugar and cinnamon.
Dip each donut hole in melted butter, then roll in cinnamon sugar to coat all sides.
