Step 1

In large saucepan, combine sugar and corn syrup (this can also be done in the microwave). Heat to dissolve sugar and bring to boil. Do not boil too long or they will harden when cooled. All you want to do here is dissolve the sugar. Remove from heat. Stir in peanut butter. Add Rice Krispies and mix until well blended. Press into buttered 9X13 inch pan.

Step 2

Melt together the chocolate chips and butterscotch chips in a microwave safe bowl or in a saucepan on the stove. You can double the topping if you want a thicker frosting but they are pretty sweet on their own already. Spread combined mixture over top of Rice Krispies mixture. Cool. Cut into bars.
