Preheat the oven to 350 degrees. Spray a donut pan with cooking spray and set aside.
In a large bowl combine the spice cake mix, egg, vegetable oil, and pumpkin. Mix well.
Place the mixture in a zip top baggie and snip off the top. Pipe the mixture into the donut pan.
Bake for 10-12 minutes or until donuts are cooked through. Remove from pan and cool on a wire rack. Repeat with remaining batter.
Before serving melt the butter in a microwave safe bowl. Combine the sugar and pumpkin spice in a second bowl.
Dip half of the donuts into the butter and then into the sugar mixture. Set on the wire rack so that any excess drips off.
In a medium bowl combine all ingredients for the glaze. Beat until smooth. Dip the remaining donuts into the caramel maple glaze and set on the wire rack so that the excess drips off.
Enjoy!
