Grease a 9x13' inch baking pan or line with parchment paper.

Rice Krispies Layer: Place cereal in a large mixing bowl. Set aside. In a large saucepan over medium heat, combine the sugar and corn syrup. Bring to a low boil and then immediately remove from heat. Stir in peanut butter until smooth. Pour mixture over the cereal and stir to evenly coat. Press firmly into prepared pan.

Chocolate Layer: Add the chocolate chips and butterscotch chips to a microwave safe bowl. Microwave on low power for about 2 minutes, stirring every 30 seconds, until melted and smooth. Spread over rice krispies layer and allow to cool completely before cutting and serving.
