Peanut Butter Rice Crispy Bars--like PCMC cafeteria :)

1 Cup Sugar
1 Cup Karo Light Corn Syrup
1 Cup Creamy Peanut Butter
6 cups Rice Krispies
1 cup Butterscotch Chips
1 Cup Semi-Sweet Chocolate Chips

Bring 1 cup sugar and 1 cup Karo Light syrup just to a boil mixing well. Take off heat and add 1 cup peanut butter and mix until smooth.
Add to the 6 cups of Rice Krispies and mix until all the Krispies are coated well.
Put this mixture into a well greased 9X13 pan and press down evenly into the pan. Empty chips into a microwaveable bowl and microwave at 3-45 second intervals, mixing well after each 45 seconds. Mix together until smooth. (You can use a double boiler method if you prefer.) Pour entire mixture on top of the pressed down Rice Krispies and spread to cover. Let them cool.
