1 c. light corn syrup
1 c. sugar
1 c. peanut butter
6 c. Rice Krispies

Topping:

1 c. butterscotch morsels
1 c. semi-sweet morsels

In a large pan, mix sugar and light corn syrup. Bring mixture to a boil, just to a boil. Remove from heat. Stir in peanut butter until smooth. Add Rice Krispies. Mix until well coated. Press mixture into greased 9 x 13-inch or 10 x 15-inch pan. Melt both types of morsels together in a saucepan or double boiler, stirring smooth. Spread over top of Rice Krispies mixture. Refrigerate until chocolate topping is solid. Cut into squares. Store in a tightly covered container. (Does not have to be kept refrigerated.)
