Mix and sift flour, soda and salt.

Melt butter.

Pour white and brown sugar and Vanilla extract into the melted butter, mix well, then add eggs and mix again.

Pour flour mixture in several takes.

Add chocolate chips and mix (not for too long, just until chocolate chips are evenly spread)

I used ice cream scoop to scoop the dough, add in baking tray covered with cooking paper. Leave about 5cm spaces. Put in 170C preheated oven and cook for about 15-17 minutes (until corners turn to golden)

Enjoy!
