A kitchen scale is more accurate than cup measurements and will give you the right ratio of dry and liquid ingredients so that the cookie dough behaves the way we want it to. I tested and developed this recipe using weight measurements. If I were to convert it to volume measurements, I would be using Google — just like you would. There's no set standard for how much "1 cup" of flour weighs (I use 120 grams, but other recipe developers use as much as 150 grams as "1 cup"), which means online converters can't truly convert accurately. Beyond that, when you scoop flour into a cup measure, depending on how you scoop it you might end up with a lot more flour than the recipe needs. Basically, if you convert this recipe to cups I can't guarantee you'll end up with the same results! Do so at your own risk.
