Topping: In a small saucepan over medium heat, melt the peanut butter chips and the cream, stirring until smooth. Drizzle the peanut butter mixture decoratively over the cooled blondies. Sprinkle the Heath Bars and the peanuts on top. Allow to cool to room temperature, or overnight, before cutting and serving.
