I saw this recipe last year on a forum and tried it. They were easy to make and were delicious too!
In top of double boiler melt together:

2/3 c. of sweetened condensed milk (Eagle Brand)
1 1/3 cups semi sweet chocolate chips

Mix together until well blended then refrigerate for several hours. Roll into balls.

Melt 2/3 cups semi sweet chips and 2 tsps oil in top of double boiler until chocolate is melted. Use spoon to roll each piece in the melted chocolate until covered. I used the remaining chocolate to drip over the tops of the candy. Let the chocolate dry and enjoy!
