- Serving: These cookies are amazing with a cold glass of milk. You can also serve them with a scoop of vanilla ice cream for a classic dessert.
- Tips & Tricks: The chilling step is a non-negotiable pro tip. It keeps the cookies from spreading too much in the oven. For the best, smoothest filling, make sure your butter is cool to the touch but still soft, and always sift your powdered sugar.
- Storage: Store the assembled cookies in an airtight container at room temperature for up to 2 days. The cookies themselves (unfilled) can be stored in an airtight container for a few days, or frozen for up to a month.
