In a medium sized bowl whisk together egg, oil, milk and vanilla. In a separate bowl combine flour, salt, sugar and baking powder. Add the dry ingredients into the wet ingredients and combine. Fold in chocolate chips.
Preheat a skillet over medium heat. Spray with cooking spray and drop about 1/3 cup of the batter onto the warm skillet. Once it forms bubbles then flip to the other side and cook until golden brown.
