Swirl the pan to spread the butter. Add graham cracker crumbs and mix them together to combine evenly. Spread the crumb mixture evenly in the baking dish and press it firmly
Sprinkle the graham cracker layer with the chocolate chips, then the butterscotch chips, then pecans, then the coconut.
Pour the condensed milk evenly over the top of all the layers.
Bake in preheated oven 25-30 minutes, until the top is nicely golden brown. Cool completely before cutting into serving pieces.
