Peanut Butter Rice Krispie Bars (Choc Scotcheroo Treats)

These peanut butter-chocolate bars are the most amazing upgraded version of the gooey, chewy version of the classic. Trust me; everyone will love them!

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 love peanut butter and have never had a “Scotcheroo,” just a fair warning. These babies are hard to stop eating!

Growing up, my Mom never made Rice Krispie treats. Those bars are made with Kellogg Company’s Rice Krispies cereal and held together by a marshmallow coating.

It was fine by me as I was never a fan. But when you add peanut butter and a butterscotch chocolate topping (and no marshmallow), you have my undivided attention.

These chocolate peanut butter Rice Krispie treats are incredibly delicious!

What is a Scotcheroo?

Chocolate Peanut Butter Rice Krispie Treats are also called Scotcheroos, a dessert bar with 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. These bars are quite famous in the Midwestern United States, 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 Kellogg’s Rice Krispies, K-Bars use Kellogg’s Special K cereal, while Oh-Henry Bars contain rolled oats.

Ingredients for Rice Krispie Bars

In my opinion, these delicious and addictive bars are the next step in your Kellogg’s 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 creamy peanut butter

3 cups Kellogg’s Rice Krispies cereal

8 ounces chocolate chips (1 cup)

8 ounces butterscotch chips (1 cup)


  1. Line a 13 x 9-inch pan with parchment paper or lightly spray with nonstick cooking spray. Set aside.
  2. In a 3.5 quart saucepan, over medium heat, combine the sugar and corn syrup. Stir frequently. When the mixture begins to boil (approximately 1-2 minutes), remove it from the heat.
  3. Stir in peanut butter immediately. When blended, mix in the cereal. Fold together until well coated.
  4. While the mixture is still warm, press into the bottom of the pan. It will get harden as it cools.
  5. 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.
  6. 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.

Cover with aluminum foil or store in an airtight container at room temperature.

    1. Jennifer, I am sorry you had problems. Refrigerate if necessary. When the chocolate is cooled, it hardens. It could be that your room temperature was too high. If the temperature is over 68 F, this can cause problems. The ideal setting temperature is between 65 and 68 degrees Fahrenheit.

  1. If you want to make these even better, add a half stick of butter to the corn syrup/sugar mixture. Makes them gooey and softer. Obviously doesn’t make them any healthier, but they’re not exactly health food to begin with.

    1. Gus, OMG butter is my middle name! This WOULD be decadent, I may need to try it! Thank you for sharing your healthy tips.😂

  2. Very yummy, added a little vanilla. made without the chocolate to try to look like hay bales
