As a general rule, having homemade cookie dough ready in your fridge is always a good idea. You never know when unexpected guests might arrive or when family time calls for a special last-minute treat. Icebox cookies are easy to keep around because you can freeze the log of dough for a month or keep it in the fridge for a few weeks.After making the dough, shaping it into a log, and chilling it for a few hours, you have a perfect cylinder of pecan-chocolate chip shortbread that is ready to slice and bake. While other icebox cookie recipes can be dry and cakey, these buttery shortbread cookies are tender and crumbly—sweet and a touch of bitter from the semisweet chocolate chips and nutty from a handful of toasted pecans that are finely chopped before being mixed into the dough. Consider it the pecan sandie-chocolate chip cookie hybrid you’ve always wanted but never knew you needed.
