What is "refrigerator cookie"?

Refrigerator cookies, also known as icebox cookies, are a type of cookie dough that is chilled in the refrigerator or freezer before being sliced and baked. The dough is typically shaped into a log, wrapped in plastic wrap, and then refrigerated until firm. Once chilled, the dough can be sliced into rounds or other shapes and baked. Refrigerator cookies are convenient because the dough can be made ahead of time and stored in the refrigerator or freezer until ready to bake. They also have a longer shelf life than regular cookies because the dough is not baked right away, which makes them a great option for busy bakers or those who want to have fresh cookies on hand without all the fuss of making a new batch every time. These cookies can be flavored with a variety of ingredients such as chocolate chips, nuts, spices, or citrus zest to create a variety of delicious flavors.
