Place the coconut in a separate shallow dish. Line baking sheet with parchment paper. Using a fork, dip 1 banana slice in chocolate, coating completely. Shake off excess chocolate. Place on the lined baking sheet. Repeat with remaining bananas. Sprinkle the top of each banana slice with shredded coconut. Place into the freezer and freeze until firm, about 3-4 hours, then serve immediately. Store the remaining banana slices in a freezer bag or sealed container. Enjoy.
