Melt butter over medium heat in a pan. Once butter is melted, add brown sugar and 2 cups dates. Cook slowly until the mixture leaves edges of pan, and stir constantly. Turn heat down slightly and add eggs that were set aside as well as the milk and salt. Cook for about 2 more minutes, then add vanilla.
Pour toasted rice cereal into a large bowl. Remove the mixture from the stove and stir it lightly into the large bowl of rice cereal.
Once the mixture is properly combined with the toasted rice cereal, butter your hands, then roll balls of the cereal mixture about the size of a large marble or a ping-pong ball in the bowl of coconut. Once the treat is covered in coconut, place it on the cookie sheet or plate and refrigerate or serve immediately.
