7 layer bars

1 c. shredded coconut
1(14oz) can sweetened condensed milk
1 c. chopped walnuts (**optional: I have never used and it still turns out really good!)

Preheat oven to 350*.Place butter in a 13X9 inch pan; melt in oven. Swirl to coat bottom and sides with butter. Take the graham cracker crumbs and spread evenly over the bottom of the pan. Layer choc. chips, butterscotch chips, (and nuts) over crumbs. Pour the sweetened condensed milk over the nuts. Sprinkle coconut over condensed milk. Bake 25 (17minutes is the top I do it) minutes or until edges are golden brown. Let cool.
