Preheat oven to 350.

Line a 9x13 baking pan with parchment.

Combine your graham cracker crumbs and melted butter. Stir until well coated. Pour into your prepared pan and press down.

Layer chocolate chips, butterscotch chips, nuts, and coconut over crumbs. Pour condensed milk over the entire thing.

Bake until edges are golden brown and the coconut is lightly toasted, about 25-35 minutes.

Cool in the pan for 10 minutes, then use the parchment paper to lift the bars out of the pan and onto a cooling rack.

Let cool completely before cutting into bars.
