Ingredients
| Ingredient | Amount | Notes |
|---|---|---|
| Special K cereal | 6 cups | Original flakes; do not use multigrain or flavored varieties |
| Corn syrup | 1 cup | Light corn syrup preferred |
| Granulated sugar | 1 cup | |
| Creamy peanut butter | 1 cup | Do not use natural or chunky for best results |
| Milk chocolate chips | 1 cup | Or semi-sweet chocolate chips for a richer flavor |
| Butterscotch chips | 1 cup | Optional but recommended for classic taste |
Instructions: Step-by-Step Guide
- Prepare the Pan: Lightly grease a 9×13 inch baking pan or line it with parchment paper for easy removal and slicing.
- Mix Sugar and Syrup: In a large saucepan, combine the granulated sugar and corn syrup. Stir over medium heat just until tiny bubbles appear and the mixture begins to boil. Do not overcook; boiling too long can result in hard bars.
- Add Peanut Butter: Remove the saucepan from heat promptly. Stir in creamy peanut butter until the mixture is smooth and fully incorporated.
- Combine with Cereal: Place the Special K cereal in a large mixing bowl. Pour the warm peanut butter mixture over the cereal. Quickly but gently stir until all flakes are evenly coated.
- Spread in Pan: Immediately press the mixture into the prepared pan, using a spatula or wax paper to flatten it evenly. Work quickly before the mixture cools and firms.
- Prepare Chocolate Topping: In a microwave-safe bowl, combine the chocolate chips and butterscotch chips. Microwave in 30-second increments, stirring after each, until melted and smooth.
- Finish and Set: Spread the melted chocolate-butterscotch mixture evenly over the cereal base. Allow the pan to cool at room temperature until the topping is set, or refrigerate for faster results.
- Slice and Serve: Cut into squares once completely set. Enjoy!
Tips for Success
- Avoid Hard Bars: Bring sugar and syrup only to a just-boiling point. Heating it too long will make your bars overly hard once cooled.
- Mix Quickly: Once peanut butter is stirred in, combine with cereal right away to ensure an even coat and avoid dry patches.
- Press Evenly: Use wax paper or a spatula to flatten, preventing cracks and ensuring uniform bars.
- Melting Chocolate: Stir frequently during microwaving to prevent burning. For stovetop, use a double boiler for gentle heating.

Frequently Asked Questions (FAQs)
Q: Can I use a different type of cereal?
A: Yes! While Special K cereal is classic, other flakes, crispy rice cereal, or even bran flakes can work as substitutions, though texture and taste may vary slightly.
Q: Is it possible to make these bars nut-free?
A: Absolutely. Replace peanut butter with sun butter, soy nut butter, or another allergy-friendly alternative. Always check allergen statements for all ingredients, especially chocolate chips.
Q: Why do my bars turn out hard?
A: The main culprit is overcooking the sugar and corn syrup mixture. Remove from heat as soon as it boils to preserve a chewy, pleasant texture.
Q: Can I double the recipe?
A: Yes! Simply double all ingredients and use a larger pan (such as a rimmed baking sheet). Mixing may be more challenging; ensure the cereal is well-coated before pressing it into the pan.
Q: How long do they keep?
A: Stored airtight at room temperature, they last up to a week. For longer freshness, freeze bars and thaw before eating.
Q: Can I substitute honey or agave for corn syrup?
A: You can, though the texture will change slightly and may become stickier or softer depending on the substitute. Corn syrup is preferred for classic results.
