Creating Crunch Bars is a fun and rewarding process. Follow these simple steps:

1. Prepare Your Pan: Line a 9×13-inch baking dish with parchment paper, leaving some overhang for easy removal later. This will also help prevent sticking.
2. Melt the Butter: In a medium saucepan, melt the unsalted butter over low heat.
3. Add Peanut Butter and Chips: Once the butter is melted, stir in the peanut butter, semi-sweet chocolate chips, and butterscotch chips. Mix until the mixture is smooth and well combined.
4. Add Vanilla and Salt: Remove the saucepan from heat and stir in the vanilla extract and salt.
5. Combine with Cereal: In a large mixing bowl, pour the crispy rice cereal. Gradually add the melted chocolate mixture, folding gently until all the cereal is coated.
6. Transfer to Baking Dish: Pour the mixture into the prepared baking dish. Use a spatula or your hands to spread and press it down evenly into the pan.
7. Chill: Place the pan in the refrigerator for about 30 minutes, or until the mixture is set.
8. Cut into Bars: Once set, lift the bars out of the baking dish using the overhanging parchment paper. Cut them into squares or rectangles as desired.
9. Store: Keep the Crunch Bars in an airtight container at room temperature or in the fridge. Enjoy them within a week for the best flavor!
