After an hour melt the 1 cup of chocolate chips in the same way. Pour into a large deep bowl and let cool for a few minutes at room.
Remove the truffles from the freezer. Place in the bowl of melted chocolate with a spoon, and spoon chocolate over it to cover, making sure to cover entire truffle.
After dipping each truffle, place it to dip on a baking rack. Refrigerate until hard, at least 1 hour.
