Scoop an additional ½ tablespoon of dough, shape and flatten, then cover each Reese's cup. Pinch the dough securely around the filling, rolling between palms to form a smooth ball. Repeat for all portions.

Remove chilled dough balls from the refrigerator. Using two forks or dipping tools, submerge each ball in melted chocolate to coat completely. Allow excess chocolate to drip off, then transfer to the parchment-lined sheet.

Immediately sprinkle remaining rainbow sprinkles over each coated ball. Refrigerate for 30 minutes until chocolate is set before serving.
