Yes, you can refrigerate cookie dough that contains cream of tartar. Cream of tartar is often used as a stabilizing agent in baking, and it doesn't negatively affect the dough's ability to be stored in the refrigerator. Just make sure to cover the dough tightly with plastic wrap or store it in an airtight container to prevent it from drying out or absorbing odors. Refrigerated dough can typically be kept for up to a week before baking.
