What makes cookies soft and chewy?

High moisture content makes cookies soft and chewy. These cookies bake up crispy.

How long should cookies cool on a rack?

Allow them to cool completely then transfer to a cookie jar or ziplock bag. Bonus? These cookies freeze beautifully!

How do you cool cookies without a wire rack?

Actually I never owned a wire rack until about 6 months ago when a brand gave me one. Seriously! I've always used a brown paper bag, which as a bonus will absorb any excess oil.

Can I use a sugar substitute?

Yes! I've used Swerve and they baked up terrific and were just as good!

Can the dough be made and frozen?

Yes! If you enjoy a freshly baked cookie, make the dough. Roll them into balls and freeze them individually. Then when you want a cookie, take them out of the freezer and bake. YUM!!
