150g/5oz granulated sugar
55g/2oz cocoa powder
40g/1½oz butter
40g/1½oz milk
1 tbsp golden syrup
450g/1lb icing sugar, sifted well - this is way too much
1 tsp vanilla extract
85g/3oz chopped nuts (optional)
basically add the gran sugar, cocoa powder, butter, milk and gold syrup together in a pan and heat until boiling. Stir constantly (at boiling point) for 3 minutes. Then take it off the heat and add the icing sugar, van extract and nuts.
I used this recipe just now but there's no way you need 1 lb of icing sugar. I added it all and had to add extra milk - I think you could probably start with half a pound and then add until you can't stir anymore (I have a feeling you will probably need 3/4 of a lb of icing sugar).
It really was incredibly easy - the kids loved making it and you don't have to add the nuts if you are worried about nut allergies.
