Classic Midwestern Scotcharoos
Scotcharoos are a no-bake Midwestern bar built on a chewy peanut butter and crisp rice cereal base, topped with a layer of melted semi-sweet chocolate and butterscotch. No oven is needed — the whole pan sets up in under 30 minutes and keeps well, making them a reliable choice for bake sales, potlucks, or a quick dessert. The combination of crunch, chew, and chocolate-butterscotch topping has kept them a staple since the 1960s.
Equipment
- 9x13-inch baking pan
- Parchment paper
- Large mixing bowl
- 3 to 4-quart heavy-bottomed saucepan
- Heatproof spatula
- Wooden spoon
- Measuring cups and spoons
- Candy thermometer (optional but helpful)
- Microwave-safe bowl or double boiler
- Offset spatula or butter knife
- Chef's knife for slicing
Ingredients
For the Peanut-Butter Crisp Base:
- 6 cups crisped rice cereal such as Kellogg’s Rice Krispies or a gluten-free variety; measure lightly without packing
- 1 cup granulated sugar white granulated sugar; superfine dissolves slightly faster
- 1 cup light corn syrup Karo Light recommended for classic texture and shine
- 1 cup creamy peanut butter shelf-stable creamy (e.g., Jif, Skippy). If using natural peanut butter, see Chef’s Tips
- 1 teaspoon pure vanilla extract real vanilla for best aroma
- ¼ teaspoon kosher salt balances sweetness; skip if peanut butter is very salty
For the Chocolate–Butterscotch Topping:
- 1 cup semi-sweet chocolate chips 60% cacao chips melt smoothly; Ghirardelli or Guittard recommended
- 1 cup butterscotch chips Nestlé or Guittard; ensure fresh for best melt
- 1 teaspoon neutral oil optional; canola or refined coconut oil for a glossy topping
- 1 pinch flaky sea salt optional garnish to sharpen flavors
Instructions
- Pan and Mise En Place: Line a 9x13-inch pan with parchment, leaving overhang for easy lifting. Lightly grease the parchment. Measure 6 cups crisped rice cereal into a large bowl so it’s ready to go.
- Warm the Syrup (do not boil): In a 3 to 4-quart saucepan, combine 1 cup granulated sugar, 1 cup light corn syrup, and 1/4 teaspoon kosher salt. Cook over medium heat, stirring, until the mixture turns clear and just begins to show tiny bubbles around the edges—about 3 to 4 minutes. Aim to stay under about 230°F (110°C); gentle simmer is okay, vigorous boiling is not. Overheating makes hard bars.
- Peanut Butter and Vanilla: Remove the pan from heat. Immediately stir in 1 cup creamy peanut butter and 1 teaspoon vanilla until the mixture is smooth, glossy, and aromatic (10 to 20 seconds). You should smell toasty peanut notes.
- Coat the Cereal: Pour the warm peanut-syrup over the cereal. Working quickly with a heatproof spatula, fold and turn until every grain is evenly coated and no dry pockets remain—about 45 to 60 seconds. The mixture should look shiny and cohesive.
- Press into the Pan: Scrape the mixture into the prepared pan. Use a sheet of lightly greased parchment or a silicone spatula to press it evenly into corners. Press firmly enough to level, but gently enough to avoid compacting (over-packing makes dense bars). Surface should look level and slightly bumpy.
- Melt the Topping: In a microwave-safe bowl, combine 1 cup semi-sweet chocolate chips and 1 cup butterscotch chips. Microwave at 50% power in 30-second bursts, stirring between each, until about 75% melted (1 1/2 to 2 minutes total). Stir to finish melting using residual heat; target a silky pool at roughly 95°F (35°C). Alternatively, use a double boiler: set a heatproof bowl over barely simmering water (about 180°F/82°C), ensuring the bowl doesn’t touch the water, and stir until smooth. Stir in 1 teaspoon neutral oil if you prefer extra gloss and softer bite.
- Spread and Set: Pour the melted topping over the base. Use an offset spatula to spread edge-to-edge, then tap the pan gently on the counter to level. Let stand at cool room temperature until the top is set to the touch, about 10 to 15 minutes, or refrigerate for 10 to 15 minutes for a quicker set. Sprinkle a pinch of flaky sea salt, if using.
- Slice and Serve: Lift the slab from the pan using parchment. For clean cuts, warm a chef’s knife under hot water, wipe dry, and slice into 24 bars. The topping should cut with a gentle snap, and the base should feel chewy, not hard.
Notes
Lisa’s Tips:
- Chewy, not Hard: Keep the syrup under a vigorous boil; stay below ~230°F (110°C). If you see big rolling bubbles, pull it off the heat immediately.
- Natural Peanut Butter: If using, stir until completely homogeneous, then add 1 to 2 tablespoons powdered sugar to help set. Expect a slightly softer, silkier chew.
- Gluten-Free: Use certified gluten-free crisped rice cereal and check chip labels.
- Dairy-Free: Swap in dairy-free chocolate chips and vegan butterscotch chips, or use all dark chocolate with 1 teaspoon refined coconut oil.
- Shinier Topping: Add 1 teaspoon neutral oil to the melted chips or gently temper the chocolate portion before mixing with butterscotch.
- Flavor Twists: Add 1/4 teaspoon espresso powder to the topping for depth, or sprinkle toasted chopped peanuts over the base before spreading the chocolate layer.
- Clean Cuts: Warm, dry knife; wipe between cuts. Slightly warm bars at room temp if cutting straight from the fridge.
- Storage: Airtight at room temperature up to 5 days, or freeze up to 2 months (layer with parchment).
