Heat oven to 400 degrees.

Mix the dry cake mix and can of pumpkin. You can add any additional flavorings that you like, but it's not necessary.

Scoop the batter into a piping bag and pipe it into the greased donut pan, filling each cavity 1/2 full.

Bake for 8-10 minutes. Check for doneness by pressing your finger into the top of the donut. If it springs back, they are done.

Cool donuts completely before adding toppings. Eat immediately.

Store plain donuts in an airtight container for up to 1 day without toppings.
