These are one of my most favorite treats, my sister's too.
As always, these are amazing!SCOTCHEROOS
1 cup sugar
1 cup light corn syrup
1 cup peanut butter
6 cups rice krispies
1 cup semi-sweet chocolate chips
1 cup butterscotch chips
Combine sugar and corn syrup in pot and cook over medium heat, stirring frequently, until mixture begins to bubble. Remove from heat. Stir in peanut butter; mix well. Add rice krispies; stir until well combined. Press mixture into buttered 13x9 inch pan.
Melt chocolate and butterscotch chip in microwave until melted (careful they don't burn). (if the rice krispie mixture is still hot, you can just put the chips on them and they should melt.) Spread evenly over rice krispie mixture. Cool until firm. Cut into bars. Makes 48, 2x1 inch bars.
