Notes
Helpful Tips From Liz
Be sure to chill the dough before baking. If you skip this step, your cookies will spread out too much in the oven, causing them to be flat and crispy instead of soft.
Let cookies cool completely before storing in an airtight container. To keep them soft and chewy, place a slice of bread in the container with them.
