Don’t add multiple tablespoons of liquid sweetener like the ones listed because they will make your cookies runny and too sweet. One tablespoon is enough to make your cookies softer but not disrupt the integrity of the dough.
The longer you rest your dough, the chewier the cookies. Professional bakers often rest their dough for several days to get the desired chewy texture. Don’t go longer than a week in the fridge though.
Make sure your cookies are not hot when you store them. Storing hot cookies in an airtight container will cause the cookies to fall apart. [10] X Research source
