Measure cereal into bowl and set aside. Spray a 9 x 13 pan with non-stick spray and set aside.
In a Dutch oven, combine sugar and corn syrup. Cook over medium heat until first bubbles appear then remove from heat (overcooking can result in hard bars). Stir in peanut butter.
Add cereal to sugar mixture and mix until cereal is evenly coated.
Spread into prepared 9x13-inch pan and press in lightly (if you press hard, cookies will come out too hard).
Prepare topping. In medium glass or ceramic bowl, melt chocolate and butterscotch chips in microwave, heating in short bursts and stirring in between. When melted, spread over cereal mixture. Let set until topping has hardened.
Cut into bars. Makes about 24 if cut into approximately 2 inch squares.
