Instructions

• Line a 9×13-inch pan with aluminum foil or parchment paper, leaving some overhang on the sides; set the pan aside.
• In a large microwave-safe bowl, combine 1 cup peanut butter, 1 cup sugar, and 1 cup light Karo syrup.
• Microwave the mixture on high, stopping to stir every 30 seconds, until the mixture is smooth and well combined.
• Add 5–6 cups Rice Krispie cereal to the bowl and stir until the cereal is evenly coated.
• Transfer the cereal mixture to the prepared pan and press it firmly and evenly into an even layer using a spatula or the back of a measuring cup.
• In a medium microwave-safe bowl, combine 1 cup butterscotch chips and 1 cup semi-sweet chocolate chips.
• Microwave the chips on high, stirring every 30 seconds, until the chocolate and butterscotch are fully melted and smooth.
• Pour the melted chip mixture over the pressed cereal layer and spread it evenly with a spatula to cover the top.
• Let the bars cool completely at room temperature until the topping is set. Use the foil or parchment overhang to lift the slab from the pan and cut into bars.
