Chocolate Fudge Sauce

In a small bowl, stir sugar and cocoa until well combined. In a medium saucepan, combine evaporated milk, butter, salt and vanilla. When butter is melted, stir in sugar mixture. Heat, stirring until it boils and is thick (about 2 minutes). You want it to coat the back of a spoon. For a thicker sauce, boil a little longer. Let cool 10-15 minutes for an even thicker consistency, Use on top of ice cream or as a filling for crepes!
