A delicious way to use up Halloween candy
Line a jelly roll pan (12" x 18") with foil and spritz with non-stick cooking spray. Arrange the Rice Krispies over the bottom of the pan.
In a medium saucepan, stir together over low heat, sugar, corn syrup, and peanut butter.
Once the mixture has melted and is smooth, pour over the Rice Krispies. Stir until all the cereal is coated and pat flat onto the pan.
Place the chocolate chips and butterscotch chips together in a microwave-safe bowl. Heat in 30 second increments, stirring after each cycle, until melted. Spread over the Rice Krispies mixture.
Before the chocolate/butterscotch spread sets, sprinkle with the Butterfinger crumbles.
Cut into bars while still warm, leaving them in the pan. Refrigerate for at least 30 minutes until firm and chocolate/butterscotch spread has set before serving.
