Cut bread in 3/4-inch intervals, being careful to not cut all the way through. Cut again, crosswise, not cutting all the way through. Place cheese in between all cuts: sprinkle with bacon. Blend melted butter and Ranch mix and drizzle over top of bread evenly. Wrap in foil and bake at 350 degrees for 15 minutes; uncover and bake 10 minutes more. Serve hot and pull apart pieces from loaf to eat!
