Preheat the oven to 325 degrees.
Place the butter in a 9″ x 13″ glass pan and melt it in the oven.
When the butter is melted, mix in the graham cracker crumbs and press down to make a crust.
Pour the sweetened condensed milk over the crust.
Sprinkle on the coconut, then the nuts, followed by the chocolate chips and butterscotch chips.
Bake at 325 degrees for 25 minutes or until the edges turn brown.
Cool completely then cut into squares.
