Classic Peanut Butter Scotcheroo Bars with Sea Salt Step-by-step instructions

Before you start

Before beginning, ensure all ingredients are measured and ready, as the process moves quickly once the melting starts. Line your baking sheet with parchment paper, leaving a slight overhang on the sides to act as handles for easy removal later.

Clear enough space in your refrigerator for the baking sheet to sit perfectly level, which ensures the topping sets evenly without pooling to one side of the pan.

Instructions

Base assembly

1. 1Prepare the base
   Combine the crispy rice cereal with peanut butter in a large bowl. Mix thoroughly until every piece of cereal is evenly coated with the peanut butter mixture. Press this mixture firmly into a parchment-lined baking sheet to create an even, compact slab.
   Look for The mixture should be sticky and hold together firmly in the baking sheet without gaps.
   Tip Use a piece of parchment paper on top of the cereal to press it down without getting your hands messy.

At the end of this phase, the cereal mixture should be uniformly coated in peanut butter and pressed into a solid, even layer. Check that the corners are filled and the surface is flat. If the mixture feels too loose, press it down more firmly with the back of a spoon or a flat-bottomed measuring cup until it feels compact and unified.

Topping application

2. 2Make the topping
   Melt the chocolate chips and butterscotch chips together in a small saucepan over low heat, stirring constantly until smooth. Pour this mixture immediately over the prepared peanut butter cereal slab. Use a spatula to spread the topping evenly across the surface, ensuring the edges are covered.
   Look for The topping should be glossy, smooth, and easily spreadable without any lumps of unmelted chips.
   Tip Remove from heat just before the chips are fully melted and continue stirring off the heat to prevent burning.

The topping should be a glossy, smooth, and uniform layer covering the entire surface of the cereal base. Ensure the chocolate-butterscotch blend has reached the edges of the parchment paper.

The texture should be consistent throughout, with no visible streaks of unmixed chocolate or butterscotch remaining before you move on to adding the final salt garnish.

Chilling and slicing

3. 3Finish and chill
   Sprinkle the flaky sea salt evenly over the melted chocolate-butterscotch topping while it is still warm and tacky. Transfer the baking sheet to the refrigerator and allow the bars to set completely for at least one hour. Once firm, cut the slab into squares before serving.
   Look for The topping should be firm to the touch and no longer tacky before attempting to slice the squares.
   Tip Clean your knife with hot water and dry it between cuts to get perfectly clean edges on your squares.

The final checkpoint occurs after the required chilling time. The topping must be completely firm and cool to the touch. Before slicing, ensure the bars have spent enough time in the refrigerator to set properly.

When cutting, use a steady, downward motion to create clean, sharp edges, resulting in professional-looking squares that are ready for immediate serving.

Common mistakes

A common mistake is overheating the chocolate and butterscotch, which can cause the mixture to seize and become grainy. Always use low heat and remove from the stove as soon as the chips have melted.

Another error is failing to press the cereal base firmly enough, which leads to bars that crumble easily. Take the time to ensure the base is packed tightly into the corners of the pan for the best result.

How to tell it’s done

The bars are considered done when the chocolate-butterscotch topping has fully hardened and is no longer tacky to the touch. The base should feel firm and solid when pressed. Use a sharp knife to test a corner; if the knife passes through with a clean cut without dragging or sticking, the bars are ready to be sliced into individual servings.
