Preheat your oven to 350°F (175°C) and grease your donut pan with non-stick spray.

In a large mixing bowl, combine the cake mix, eggs, oil, milk, and vanilla extract. Mix until smooth, about 2-3 minutes.

Transfer the batter into a piping bag and fill the donut pan about 3/4 full.

Bake for 10-12 minutes until light golden brown and a toothpick comes out clean.

Cool in the pan for 5-10 minutes before removing to a wire rack.

Prepare the glazes by mixing powdered sugar with milk to desired consistency in separate bowls.

Dip the cooled donuts into the glaze and add sprinkles if desired.

Allow the glaze to set for about 10-15 minutes before serving.
