2) Form dough into doughnuts and poke a hole through them. Drop them into hot grease and brown them on both sides until they were done about 2 minutes on each side. Don't forget to flip often.
3) Melt the chocolate and butter in a saucepan over very low heat. Stir in the sugar, alternating with the evaporated milk, blending well. Raise the heat to medium and bring to a boil, stirring occasionally. Lower the heat and cook, stirring, until the mixture becomes thick and creamy, about 8 minutes. Stir in the vanilla, remove the pan from the heat.
4) Dip cooked doughnuts immediately into the chocolate mixture before the chocolate starts to cool. Add topping/toppings of your choice.
5) Place the doughnuts on a plate and serve when the chocolate on the doughnuts sets, about 5 minutes.
Note: In the US you can buy American biscuits ready made in a tin. To substitute, see Paula Deen's recipe for American biscuits.
