1 c white corn syrup (Karo)
2 Tbs butter
1 c creamy peanut butter
6 c rice krispies

1/2 c semi-sweet chocolate chips

In a heavy saucepan cook sugar, syrup, and butter over a medium heat, until sugar is dissolved. 
Remove from heat and add peanut butter. 
Place rice krispies in a large bowl and gently stir in syrup mixture until krispies are coated and press firmly into a buttered 9x13" pan.

In a double-broiler melt butterscotch and chocolate chips until soft and creamy.  Then pour and spread over the bars.

When they are cool you can cut.
