In a small saucepan over medium-low heat — or in a microwave-safe bowl in 30-second intervals — combine the peanut butter, chocolate chips, and butterscotch chips. Stir continuously until everything is completely melted and the mixture is smooth and glossy. Pour and spread this chocolate topping evenly over the final cracker layer, covering it completely.
Step 6: Chill and Serve
Cover the pan and refrigerate for at least 1 to 2 hours, or until the chocolate topping is fully set and firm. Once set, use the foil overhang to lift the entire slab cleanly out of the pan. Place it on a cutting board and slice into bars of your preferred size. Serve chilled directly from the refrigerator for the best texture and flavor.
Tips for Perfect Bars Every Time
- Stir the caramel constantly for the full 5 minutes — stopping or rushing this step is the most common reason the caramel does not set properly
- Chilling is essential — do not try to cut the bars before the chocolate topping has fully hardened
- Use real butter in the caramel layer for the richest, deepest flavor
- Chill, do not freeze — the bars stay perfectly soft and cuttable when refrigerated, which is actually better than freezing for serving
- Cut cleanly by running a sharp knife under warm water before each cut for neat, even slices
