Preheat the oven to 350°F and grease a muffin tin.
Whisk the milk and vinegar in a small bowl and set aside.
In a large mixing bowl, whisk the flour, salt, baking soda and powder, and sugar.
Add the canola oil and vanilla to the milk mixture and whisk again.
Add the wet mixture to the dry and mix until just combined.
Fold in the chocolate chips.
Pour equal sized portion into the prepared muffin pan, filling each about 3/4 of the way (this recipe will make about 12 muffins).
Bake for 18-22 minutes, until a toothpick comes out clean or with just crumbs.
