What Are Special K Bars?
They are a no-bake dessert bar made with Kellogg’s Special K cereal. They are made with peanut butter and topped with a butterscotch and chocolate topping. Each bite is a crispy, chewy, sweet treat.
I love to make these for all kinds of occasions – they’re great for potlucks and parties. I’ve made them for bake sales and the kid love to have them for after school snacks. They’re also great for the kids soccer games or other sports practices as a special treat.

- Creamy peanut butter or you can use chunky peanut butter if you want to add a little more texture to the bars.
- Vanilla
- Special K Cereal – I highly recommend using this brand of cereal, but you can make them with plain corn flakes, too.

How to Make Special K Bars
Make the peanut butter mixture: In a large saucepan, Heat the sugar and corn syrup over medium-low heat. Stir frequently and don’t let the mixture boil. Once the sugar is dissolved, add the peanut butter and vanilla. Stir to combine and remove the pan from the heat.
Make the bar mixture: Pour the cereal into a large bowl and add the peanut butter mixture. Stir to coat the cereal evenly in the peanut butter. Transfer the mixture to the prepared pan and press it into an even layer.






Make the topping: Place the butterscotch chips and chocolate chips in a microwave-safe bowl. Heat them for one minute and stir. Microwave them again in 10 to 15-minute increments or until they are melted and smooth. Spread the mixture over the bars in the pan.
Chill: Place the pan in the refrigerator for 15 to 20 minutes or until the topping is firm. Cut into bars and serve!


Pro Tips!
- Make sure you work quickly. If the syrup mixture firms up it’s hard to work with.
- Do not use a “natural” peanut butter. Go for the emulsified peanut butter with no oil on top.
- Want thicker bars? Use a 8×11 inch pan instead of the 9×13 inch pan.

The key to soft and chewy bars is not overcooking the sugar and corn syrup mixture. You want to heat it but not let it boil, so keep an eye on it and adjust the heat if necessary.
If you keep them in the refrigerator they will also harden, so it’s a good idea to let them sit out at room temperature to soften before serving them.
They will keep well for up to a week at room temperature in an air tight container in a cool, dry place. You can keep them in the fridge, too, but they will harden and will need to sit at room temperature to soften. You can also freeze them!
