In a large bowl, toss together flour and nuts and set aside.
In a medium saucepan combine chocolate chips and butter, stirring over very low
heat until chips are melted and smooth. (Mixture will be stiff.)
Add sweetened condensed milk and vanilla extract to chocolate mixture; mix well.
Add chocolate mixture to flour and nuts; mix well. Shape 1 tablespoon of dough around
each candy kiss, covering it completely.
Shape into a ball and place 1 inch apart on an ungreased cookie sheet.
Bake for 6 to 8 minutes. Do not over-bake. Cookies
will be soft and appear shiny but will become firm as they cool.
Remove from cookie sheets. Cool for 15 minutes or until completely cooled.
Chocolate Topping: Melt chocolate chips in a small saucepan with vegetable oil
and stir until smooth. Dip just the top of each cookie into the melted chocolate
and set on rack to cool and firm chocolate.
