Peanut Butter Rice Krispie Bars with chocolate on a plate and also stacked.

Peanut Butter Rice Krispie Bars

Peanut Butter Rice Krispie Bars are a favorite in my husband’s family. This tradition was upheld for years by his dear Aunt Marsha. We continue to honor her and her legacy of recipes by making and enjoying many of her treats! ❤️

If you have never had a “Scotcheroo”, just a fair warning. These babies are addictive!

Growing up, my Mom never made Rice Krispie treats. It was fine by me as I was never a fan. BUT, when you add peanut butter and a butterscotch chocolate topping, you have my undivided attention.

What is a Scotcheroo?

Peanut Butter Rice Krispie Bars are also called Scotcheroos; a dessert bar that has a Rice Krispie and peanut butter base, with a creamy chocolate butterscotch topping.

The recipe was originally printed on the Rice Krispies box in the mid-1960s. In the Midwestern United States, these bars are quite famous but there are a few variations with slightly different names and ingredients.

The Difference between Scotcheroos, Special K Bars, and Oh Henry

You may have heard them called Scotcheroos, Peanut Butter Krispies, Special K Bars, K-bars, or Oh-Henry Bars.

You may have seen them at potlucks and gatherings across Minnesota, Iowa, or Wisconsin.

They are all very similarly delicious! The main distinction seems to lie in the type of cereal or grain you choose. Scotcheroos use Kelloggs Rice Krispies, K-Bars use Kelloggs Special K cereal, while Oh-Henry Bars contain rolled oats.

Peanut Butter Rice Krispie Bars or Scotheroos have only 6 ingredients and take less than 30 minutes.

In my opinion, these delicious and addictive bars are the next step in your Kelloggs Rice Krispie treat journey. Waaaay better than the plain variety. If you are ready to move up to the next level of flavor, make this recipe STAT! You’re welcome.



1/2 cup Granulated Sugar
1/2 cup Karo Light Corn Syrup
3/4 cup Peanut Butter
3 cups Kellogg’s Rice Krispies Cereal
6 ounces Chocolate Chips
6 ounces Butterscotch Chips


Line a 13 x 9inch pan with parchment paper or lightly spray with cooking spray. Set aside.

In a 4-quart saucepan, over medium heat, combine the sugar and corn syrup. Stir frequently. When the mixture begins to boil, remove it from the heat. Stir in peanut butter. When blended, mix in the cereal. Fold together until well coated.

While the mixture is still warm, press into the bottom of the pan. It will get harden as it cools.

Melt the chocolate and butterscotch chips, using a microwave or a double boiler. Stir frequently. When melted, pour over the cereal mixture. Spread evenly with a spatula.

Cool before cutting into squares. Enjoy!


Add the peanut butter to the sugar mixture shortly after the sugar melts into the corn syrup. Do NOT overcook, or the bars will be stiff and chewy.
