1 can sweetened condensed milk
1/4 lb. butter
1 pkg. German sweet chocolate (in pieces)
2 c. sugar
Vanilla to taste

Put sugar and milk in heavy saucepan. Heat until sugar melts. Add chocolate and cook, stirring constantly until it cooks from side of pan when pan is tilted. Add butter and vanilla and beat by hand until smooth. Put on buttered plate or cookie sheet until cool. This is very rich so cut in small squares to serve.
