When it comes to comfort food, there are few treats as beloved as these old-fashioned Scotcheroo bars. They’re a mix of chewy, crispy, and chocolate-peanut-butter-butterscotchy goodness that has been around for as long as you can remember. And they’re so simple to make.

A Bit of Scotcheroo History

Scotcheroo bars first made their appearance in the 1960s, courtesy of a recipe from the makers of Rice Krispies cereal themselves. They were part of a promotional effort to showcase the versatility of the cereal beyond breakfast. Their goal was to create a treat that was easy to make and loved by both kids and adults. I’d say it was a success!

The original recipe featured the combination of peanut butter, butterscotch, and chocolate that quickly became famous. Over the years, Scotcheroos have become a staple at potlucks, family gatherings, and bake sales—they’re a timeless favorite.

The Ingredients

• 1 cup Karo syrup
• 1 cup peanut butter
• 1/2 cup sugar
• 6 cups Rice Krispies
• One package chocolate chips
• One package butterscotch chips
• 1/4 cup peanut butter (for the frosting)

How To Make Old-Fashioned Scotcheroo Bars (it’s so simple)

1. Combine Ingredients: In a large saucepan over medium heat, combine the Karo syrup, peanut butter, and sugar. Heat until the mixture is melted and smooth, stirring often to prevent burning.

1. Add Rice Krispies: Fold in the Rice Krispies using a large spoon or rubber spatula. Stir until they’re fully coated with the peanut butter mixture.

1. Press into Pan: Turn the mixture out into a 9 x 13 pan. Using a piece of parchment paper, press the mixture evenly into the pan.
2. Melt the Chips: In a large glass bowl or measuring cup, combine the chocolate chips, butterscotch chips, and 1/4 cup peanut butter. Heat in 30-second increments, stirring after each, until the chocolate mixture is melted and smooth.

1. Spread the Frosting: Pour the chocolate mixture over the bars. Using a large spoon or rubber spatula, spread the frosting evenly over the top.

1. Set and Serve: Place the bars in the refrigerator for 1 hour to set up. Once set, slice into 24 bars and enjoy.

A Few Tips and Tricks

• Smooth versus Crunchy Peanut Butter: While the recipe calls for smooth peanut butter, you can use crunchy if you prefer a bit of extra texture in your bars.
• Natural Peanut Butter: It’s best to avoid using a natural peanut butter for this recipe, because the oil separation can affect the consistency of the bars. Sadly, it’s just not the same.
• Mix-Ins: Get creative! Add a handful of mini marshmallows or a sprinkle of sea salt on top of the frosting for an extra layer of tastiness.
