Preheat oven to 425°F, and grease donut pans, including the center.
In the bowl of a stand mixer, cream the sugar with the oil until well combined.
In a separate bowl, combine the flour, salt, and baking powder. Whisk until incorporated.
To the sugar/oil mixture, add the milk, eggs, and vanilla. Mix until well combined.
Add the flour, salt, and baking powder mix to the combined wet ingredients.
Mix until combined and no lumps remain.
Add in the chocolate chips, and mix until evenly distributed.
Pour batter into a piping bag fitted with a large open tip. If you don't have a piping bag, use a large resealable bag and snip about a half inch of the corner off.
Pipe the mixer into the greased donut pans, filling them about halfway. Do not cover the center peg, where the hole will be when they are done.
Check the donuts at 8 minutes to see if they're done or need a few minutes longer.
Remove from oven, and cool in the pans for five minutes.
