Special K Bars

If your Special K Bars have ever turned hard, crumbly or dry, you're not alone. This old-fashioned Midwest reipe is famous, but one small mistake can ruin the texture. I'll show you exactly how to make soft and chewy Special K Bars every time.

These bars are closely related to Scotcheroos. Traditional Scotcheroos use Rice Krispies cereal, while these Special K Bars use a more flat, flaked cereal, which holds more of the peanut butter mixture and creates a softer texture. Many home bakers actually prefer this version because it's more reliable.

Want a dessert with a brownie twist? Try these easy brookie bars, or if you're in the mood for something nostalgic and peanut buttery, my three-ingredient peanut butter cookies are a reader favorite.

If you grew up in the Midwest, you probably had these at potlucks, bake sales, or school events. They’re one of those dependable no-bake desserts people bring when they need something quick that always disappears.

Special K Bars vs Scotcheroos (Which is Better?)

Scotcheroos use Rice Krispies cereal. Technically, Scotcheroos are a Rice Krispie treat. To many people, the bar names are interchangeable. Both bars are quick, easy to make, and have a delicious peanut butter flavor!

Ingredients

• Special K Cereal or a store brand also works.
• Light Corn Syrup
• Smooth Peanut Butter - I use a commercial-type smooth peanut butter (Use a brand like Jiff or Skippy or a store brand). I don't use all-natural peanut butter because I find the recipe may not turn out as well. It has to do with how the oil separates in the organic and all-natural brands.
• Butterscotch Chips - If you find you don't have any, you can just add axtra chocolate chips.
• Chocolate Chips
• Sugar

Shopping Tip

Below is what light corn syrup looks like. This is a popular brand you will find in most stores. It's a clear liquid, and you can find it in the baking aisle.

Important Prep tip!

Read through the whole recipe and pre-measure everything. You need to work fast, and the best way to do that in this recipe is to have everything measured and ready to go. If you let the ingredients boil too long or too hard, the final bars can be hard.

Instructions

Step 1
In a large saucepan, add light corn syrup and sugar. Heat on medium heat until just melted and starting to boil.  I usually watch for the bubbles on the side of the pot, like the picture below.   The mixture does NOT need to come to a rolling boil.

Step 2
Turn the heat off as soon as you have added the peanut butter.  Stir until smooth and remove from heat.  Do not overheat this mixture. It can make these bars hard.

Step 3
In a large bowl, add the sugar and peanut butter mixture into six cups of Special K cereal.

Step 4
Dump the cereal, peanut butter, and sugar mixture into a well-sprayed or lined 9 x 13 casserole dish.  I line the casserole dish with parchment paper.  

Helpful Hint - Over your kitchen sink, spray nonstick spray on the back of a large spoon or spatula. The cereal mixture will be easier to spread this way.
It's okay to use a little pressure to compact and flatten the cereal mixture.

Step 5
Melt the chocolate chips and butterscotch chips together. You can melt it on a stovetop with a double boiler or microwave. Use just enough heat to melt, or the chocolate will seize.

Step 6
Pour melted chocolate and butterscotch chips into the cereal mixture, spreading quickly to have a nice, thin, even layer.  Work quickly so the chocolate doesn't harden before it's all spread. It is a thin layer and covers the cereal mixture.

Step 7
Cool slightly and then cut into squares. I let it sit on the counter (or the fridge) for a few minutes then cut it when the chocolate layer has hardened

I like having parchment because you can take out everything in one piece.  Then, it's easier to cut into squares.

I like cutting it into smaller pieces, roughly 2 square inches. People tend to enjoy 2 small pieces rather than 1 big piece.

Problem solving - Why did my Special K bars turn hard?

• sugar mixture overheated
• do NOT boil
• remove heat once dissolved
• sugar crystallization causes hardness

Problem solving - Why won’t my chocolate topping spread?

• chips overheated - the chocolate has seized
• cereal layer cooled too long
• heat chips until just melted and spread quickly onto cereal layer

Storage Tips

Store in an airtight container at room temperature for up to 4 days. They can be refrigerated but should be allowed to come to room temperature before eating, or they will be hard.

Wrap well if freezing. Place parchment paper between layers. Make sure to give enough time to warm to room temperature before eating.
