Mix together softened vanilla ice cream (you can soften it in the microwave on defrost for up to 1 minute), crushed coconut cookies, semi-sweet chocolate chips and chopped cherries. Refreeze for at least 1 hour.
When ready to serve, scoop ice cream into 6 serving bowls. Top with heated hot fudge sauce or chocolate syrup and nut topping. Garnish each sundae with a whole cherry and serve.
