Preheat oven to 375 degrees F, grease or line a 12 cup muffin tin, set aside.
In a large mixing bowl combine the oil, sugars, eggs, milk, and vanilla extract. Whisk until combined.
In a small mixing bowl combine the flour, baking powder, baking soda, and salt, stir to combine.
Add the dry ingredients into the wet and fold in until completely incorporated. Gently fold in the mini chocolate chips. Use a 1 oz. portion scoop to fill each muffin cup 2/3rds full.
Bake at 375 for 25-30 minutes, until a toothpick inserted into the middle comes out clean. Transfer to a cooling rack and allow to cool slightly before enjoying!
