Fill pan cavity to the top edge with melted candy. Tap on counter to remove air bubbles. Let chill for 8 to 10 minutes or until a 1/8 to 1/4 in. shell has formed.
Pour out excess candy then return shell to refrigerator to chill completely. Carefully unmold shells (if you have difficulty removing shells, place pan in freezer for 2-3 minutes, then unmold). Smooth top edges by sliding across warmed cookie sheet or warming plate. Excess candy can be reheated and reused.
