Turn the dough out onto a smooth work surface and squeeze it so that it sticks together in large clumps. Gather the dough into a ball, divide it in half, and working with one half at a time, shape the dough into logs that are 1 1/2 inches (4 cm) in diameter. Wrap the logs in plastic wrap and refrigerate them for at least 1 hour. (You can refrigerate the wrapped logs for up to 3 days or freeze them for up to 1 month.)☞ TESTER TIP: Cookie dough logs have a way of ending up with hollow centers, so as you're shaping each log, flatten it once or twice and roll it up from one long side to the other, just to make certain you haven't got an air channel.
