Preheat the oven to 350 degrees Fahrenheit and spray a donut pan with a non-stick cooking spray.
Mix together the cake mix, egg, vegetable and milk with a hand held mixer or stand up mixer until well combined.
Pour the mixture evenly into the donut pan filling each one about halfway full. I find that it’s easiest to use a piping bag to fill the donut pan or place the batter in a large ziplock bag and cut the corner off the bag to pipe the batter into the pan.
Then bake for 10-13 minutes until a toothpick inserted into the center of the donuts comes out clean. Let the donuts cool in the pan for 5 minutes and then transfer them to a wire rack to cool completely.
For the Glaze:
In 2 separate bowls, whisk together the glaze ingredients and the chocolate glaze ingredients.
Dip half the cooled doughnuts in the vanilla glaze and dip the other half of the donuts in the chocolate glaze covering about half of the donuts. Then top with the sprinkles at this time.
Let the donuts cool (so the glaze can set) for approximately 30 minutes before serving.
Then enjoy!
Notes
Store the leftover donuts in an airtight container at room temperature for up to 1 week.
