Dana's no-fail Orange and Cinnamon Fudge

I am a self professed pretty-good-baker and equally-good-cook. But I have a secret shame, despite the many amazing things I can bake - I can't make fudge... There, I said it.
I do, however, have an amazing no fail fudge recipe that is perfect for this time of year. It is done over a low heat (or a microwave if you like) and is a simple one that kids can help with. It makes great gifts for friends or teachers.

Ingredients:
1 can condensed milk
600g chocolate chips or buttons or chopped chocolate (about 3 cups)
8 drops of orange oil or 1/4 teaspoon of orange essence
1/2 teaspoon of ground cinnamon.

Line a 20x20cm tin (or similar) with tin foil.
Melt the chocolate with the condensed milk over a low heat stirring constantly. Or microwave in 30 second bursts, stirring in between.
Once all the chocolate is melted add the orange flavour and the cinnamon and stir until smooth.
Pour into the tin and leave to set in the fridge.

Notes: 1) You can buy orange oil in kitchen speciality shops.
            2) You can replace the orange flavour and cinnamon with 1 teaspoon of vanilla and
                1/2 cup chopped nuts.
           3) Use this recipe to pour in to cookie cutters that have been wrapped in foil so it
               doesn't run out the bottom. Let the kids decorate the tops with lollies or silver balls.
               Once set remove the foil from the bottom and wrap in cellophane to give as gifts to
               teachers.
