What you need is:
- A packet of biscuits (Digestives usually)
- A large can of sweetened condensed milk (less 3 tbsp)
- 125g margarine, melted
- 7 tbsp dessicated coconut + some extra for topping
- 7 tbsp cocoa powder
Be sure to put the packet of biscuits into a plastic bag securely sealed before attempting this or you'll end up with more biscuit over your floor than anywhere else. Try to make sure there are no solid pieces left, you might need to sift through the crumbs with your hands to get it done.
Once it's properly mixed up, pour it onto a sheet of foil (it won't be too hard, it'll generally fall out of the bowl in a blob) and put into the fridge overnight - or for as long as possible - to settle.
The next day, sit yourself down with a pair of clean, jewellery-free hands, a plate of dessicated coconut, and the plate where you plan to present these beauties.
Get rolling (each one approx 1 inch), coat each ball with coconut and place on the plate. Your hands WILL get messy, but it washes off easily.
I'll be taking some in to work tomorrow too... I can't possibly allow myself to eat the amount of chocolate there is currently in the house... or could I?
