Stained-Glass Sugar Cookies
Filling the cutouts of these sugar cookies with crushed hard candy yields the most striking stained glass effect.
To crush the hard candy, seal in a zip-top bag and pound with a meat mallet or small skillet.
Disks of dough can be refrigerated overnight or frozen, up to 1 month, and thawed in the refrigerator. Let sit at room temperature until soft enough to roll. Cookies can be stored in airtight containers, up to 1 week.
