Chocolate Brown Sugar Peanut Fudge

Sugar (brown),22/3 cups
Milk,½ cup
Chocolate,2 squares
Butter,1 tablespoon
Flavoring (vanilla),1 teaspoon
Peanuts (shelled),½ cup

While the sugar, milk, chocolate and butter were cooking, Betsey shelled the peanuts. When the candy was sufficiently cooked, so that a little of it, dropped in cold water, formed a soft ball between the thumb and finger, it was removed from the fire and the saucepan stood in a pan of cold water. Betsey next added the nuts and vanilla, beat the fudge till it was thick like heavy cream, poured quickly into the buttered pan and marked in squares.
