Put the skewered banana halves in the freezer for 15 minutes. (alternatively, put the bananas in a airtight container or wrap tightly in foil and freeze them for as long as 2 days. Allow them to defrost for about 15 minutes before using them).

Have the chocolate, salted peanuts and coconut out in 3 separate shallow plates or bowls and let the guests dip and garnish their frozen bananas to their liking.
