Preheat the oven to 180C/350F degrees.
In a bowl add the egg whites and coconut. Mix well.
Add the sweetener and melted butter and stir well.
Grease a muffin tin lightly.
Place a spoonful of the coconut mixture into the muffin tin and press down to make the shell. Add more mixture if necessary.
Bake for 8-10 minutes until slightly golden. Cool in the tin.
Gently heat the cream and add the chocolate.
Whisk until the chocolate is combined thoroughly, then pour into the coconut cups.
Chill in the fridge for 2 hours.
Remove from the tin, eat and enjoy!
