1Heat oven to 350 degrees F. Line a 13 x 9 x 2 baking pan with foil, extending foil over pan's edges. Put butter in the pan and place in oven for about 5 minutes, or until butter melts. Tilt pan to coat evenly. Sprinkle with crushed graham crackers; layer with nuts, chocolate chips and coconut. Drizzle with fat-free sweetened condensed milk.
2Bake for 20 to 25 minutes, or until edges are lightly browned. Cool in pan, on a wire rack, for 15 minutes. Use foil to lift from pan and then cut into bars (I used my pizza rolling cutter for this). Let cool completely.
