Preheat oven to 180 degrees. Grease an 8 inch pan well. Add all the dry ingredients into the prepared pan and whisk well.
Pour the oil, vinegar and vanilla in three different spots of the dry ingredients.
Add the milk on top and slowly stir with the whisk till the batter is well combined and without any lumps.
Sprinkle the chocolate chips on the top.
Bake in the oven for 30-40 minutes till the tester comes out clean.
Cool in the tin for around 15 minutes. Cut out from the pan and enjoy as it is, or with a scoop of ice cream on top - awesome as a meal-ending dessert!!!
