Fudgie-Scotch Squares

My ABSOLUTE favorite Christmas dessert!!

1 cup semi-sweet chocolate morsels
1 cup butterscotch morsels
1 cup chopped walnuts
3/4 cup graham cracker crumbs
1 can sweetened condensed milk

Mix ingredients, press into a well-greased baking dish (9x9), and bake at 325 for 30 minutes.
