Add the softened cream cheese and brown sugar to a medium bowl. Using a hand mixer, beat until smooth and creamy.
Spread the cream cheese mixture evenly into a shallow serving dish or small plate.
Pour half of the caramel sauce over the cream cheese layer.
Sprinkle half of the Heath bar pieces over the caramel.
Drizzle the remaining caramel sauce over the top, then sprinkle with the remaining Heath bar pieces.
Serve immediately with sliced apples, or cover and refrigerate until ready to serve.
