Optional, reserve 1 - 2 tablespoons of sweetened condensed milk.
Mix together graham cracker crumbs and melted butter, and press firmly onto the bottom of a parchment lined or greased 9x13 inch casserole dish.
Pour the can of sweetened condensed milk evenly all over the graham cracker crumbs.
Layer the chocolate chips, butterscotch chips, coconut flakes and walnuts and press down firmly. Drizzle remaining sweetened condensed milk over top, if desired.
Bake at 350F for 25 minutes, until coconut has started to turn a golden brown. Allow to cool completely before cutting.
