Mix flour, baking soda and salt nicely. You can also sieve them.

Take the butter kept at room temperature. Beat it with sugar until creamy. Use powdered sugar to make this easy. You can also use brown sugar for better colour. Add vanilla essence and beat again till it's nice and creamy

Now add the flour mixture and chocolate chips to this creamed mixture. Mix till it is crumbly. Now add milk slowly as needed to form a smooth cookie dough. Do not over mix just till the whole dough comes together. And it is ok to add more chocolate chips I mean that thing is measure with heart.

Preheat your oven 180 degrees for 10 minutes. If you are using Convection Microwave then preheat till 200 degrees. Take your baking tray and spray oil on it. or you can lay a parchment paper.

Make small balls from the dough. Remember cookies will spread when they bake so it is safer to make small size roundels. Press them slightly. If you find your dough wet you can keep it in fridge for half hour before this step. Or after making dough balls you can keep it in fridge for 10 minutes before sticking it into the oven.
