Preheat the oven to 180°C for at least 10 minutes.

Take dry ingredients (maida, salt, and baking soda) in a bowl. Whisk it till they incorporated and keep it aside.

Take soften butter in another bowl. Beat it with wire whisk or by electric mixer till it becomes creamy and smooth.

Then add both sugars. Again beat till it becomes fluffy (about 2 minutes).

Then add vanilla extract and milk. Whisk till it gets incorporated.

Add dry ingredients and choco chips. Mix it until incorporated and fold them in.

If the dough looks soft and sticky than chill it into the refrigerator for about 30 minutes.

Now make 1-inch size balls from chilled cookie dough. Place on the greased tray a few inches apart from each other, because they will spread as bake. Flatten it slightly using back of glass or bowl or use your fingers.

Bake them for 10-12 minutes in preheated oven or until the edges are become golden brown.

Let it cool for 5 minutes. After that, remove it to the cooling rack to cool completely.

Cookies are ready.
