Preheat oven to 325°F. Grease a 9"x9" square pan. Line with aluminum foil, let it hang over edges on opposite sides. Grease the foil.
In a small bowl, mix the melted butter and graham cracker crumbs together. Pour into prepared pan. Press down to evenly cover bottom of pan.
Prepare the brownie batter according to the package instructions, using the egg, oil and water. Pour on top of cracker crust. Place the waffles on top of the brownie batter. Gently turn waffles, so brownie batter covers both sides. Pour in sweetened condensed milk. Sprinkle coconut, chocolate chips, butterscotch chips and nuts on top. Bake for 35-40 minutes or until light golden brown around the edges. Place in refrigerator to set for 1 hour. To serve, run a knife around edges to loosen bars. Using foil, lift bars up and out of pan. Slice into squares. Serve. Store in refrigerator.
