Spray donut pans with non-stick cooking spray or grease lightly with coconut oil, set aside.
Whisk together dry cake mix, spices, vanilla, egg, vegetable oil, and water until combined.
Pour batter into a large, gallon sized plastic bag and snip off small portion of one corner. Squeeze donut mix into prepared donut pan until cups are about ½ full.
Bake at 350 degrees F for 12-14 minutes.
Let donuts cool in pan for about 5-10 minutes then remove and let cool completely on wire rack.
For the Glaze
In a medium sized bowl, whisk together butter, powdered sugar, and milk until just combined.
Dip the cooled donut about ½ way into the glaze then lift and turn sideways to let extra run off. Place back on wire cooling rack.
Repeat with remaining donuts.
Top with optional toppings and enjoy!
