In a large mixing bowl, combine the yellow cake mix, pumpkin puree, and pumpkin pie spice. Stir until smooth and thick, about 2-3 minutes.

Grease a donut pan generously with non-stick spray and fill each cavity about 2/3 full with the batter.

Preheat your oven to 350°F (175°C). Bake for approximately 10–12 minutes, or until tops are golden and spring back when pressed.

Remove the donut pan from the oven and allow it to cool for 5 minutes, then flip onto a wire rack.

Prepare the spiced sugar coating by sifting together powdered sugar and additional pumpkin pie spice in a shallow bowl.

Once cooled, roll each donut in the spiced sugar coating until fully covered, ensuring even coverage.
