Add in Oil and water .Mix everything really well with a whisk until all the ingredients are well combined. Make sure the sugar is also dissolved.
Take the measured Choco chips in a bowl and add in 2 tbsp of Wheat flour and toss really well, such that all the Choco chips are coasted with flour. In another bowl take Wheat flour, Baking powder and Baking soda and sieve it twice or thrice until all the dry ingredients are well combined.
Now combine the dry and wet ingredient little by little and combine well, make sure no lumps are there. Next add in the flour coated Choco chips and combine the batter really well with a spatula.
Now pour the prepared batter into the lined Muffin cases. You can use an ice cream scoop/Ladle to pour the batter equally in to the muffin cases. Fill ¾ of the Muffin cases as the Muffins will raise while baking. Pre heat the oven in 180 deg C for 10 mins and then bake the muffins in 180 deg C for about 15-17 mins or a toothpick when inserted comes out clean.
