Chocolate mint slice

A favourite recipe from school days. If peppermint is not to your liking, just ice with your favourite icing.

  • 250 grams butter, melted

  • extra coconut, to decorate

  • peppermint to taste
  • 2-3 tablespoons warm water or milk
  • simple chocolate icing
  • 1½ cups icing sugar

The peppermint slice was excellent and sharp the way I like it. I used peppermint essence in the peppermint icing and had to add quite a bit to get the sharp flavour, but it is your personal preference how much you want to add. The chocolate icing should be quite thick as mine was runny (don't add too much water), it is quite annoying. Otherwise the sugars go really well and taste great!
