Melt 1 stick of butter in 13x9 pan in warm oven. Mix in 1 cup of graham cracker crumbs and press into crust on bottom. Layer 12 oz of chocolate chips, 6 oz of other flavored chips if desired (butterscotch, mint, cinnamon, etc), 1 cup chopped nuts, a few handfuls shredded coconut. Drizzle 1 can sweetened condensed milk on top. Try to avoid having the layered ingredients or the milk touch the edges of the pan because it will stick. Bake at 350 until everything is melted and just slightly browned on top (20-30 minutes? Can't remember.) Cool completely before cutting. Cut small-ish pieces because it's very rich. Leave generous plateful with big glass of milk for Santa to ensure plentiful presents.
