You are going to love these peanut butter butterscotch Rice Krispie treats! With this simple microwave scotcheroos recipe, you can cut down on the wait and effort to devote more time to more important things-like eating!
I am a huge fan of Rice Krispie scotcheroos, as is my family. While these scotcheroos might look a lot like my Chocolate Peanut Butter Rice Krispie Treats, there's no mistaking the delicious butterscotch taste and smell in every square.
Why This Recipe Works
- No marshmallows are needed. Unlike many other rice krispie treat recipes, we're making these peanut butter butterscotch rice krispie treats without marshmallows! The results are fabulous, soft, and irresistible.
- The microwave is quick and convenient! Cut down on time, energy, and dishes by simply using the microwave. No more waiting for sugar to boil over a hot stove.
- Perfect results every time. With this easy scotcheroo recipe, you can get a perfectly made batch of scotcheroo bars every time. The minimal effort you get to apply to making it is just an added bonus!
Granulated Sugar- Heated granulated sugar becomes smooth and hard like a glue, which helps to hold our cereal bars together.
Light Corn Syrup- This helps to prevent sugar crystals from forming in the mixture, which means your cereal treats will have the perfect consistency.
Creamy Peanut Butter- While you can use chunky peanut butter, creamy peanut butters like Jif or Skippy are what we like to use. Note that natural peanut butters will not work because the consistency is different.
Crispy Rice Cereal- Use a cereal like Rice Krispies for the base of this treat recipe. Off-brand versions work just fine!
Semi-Sweet Chocolate Chips- We prefer the treats with semi-sweet chocolate chips, but milk chocolate chips are great too!
Butterscotch Chips- These yield the best flavor and add to the creamy consistency in the topping.

Check out how to make scotcheroos with these simple step-by-step instructions:
Grease a 9x13 baking dish and then set it aside.
In a large microwave safe bowl, combine your corn syrup and sugar.
Microwave on high for 1 minute 30 seconds to 1 minute 45 seconds depending on the strength of your microwave. Be careful not to let the mixture boil.
Mix the sugar and corn syrup with a whisk until the bowl is no longer hot and the sugar looks dissolved.
Add in the peanut butter.
Stir together until blended. Don't be afraid to get your hands in there and mix everything if it's too thick for your spoon to handle.
Add in half of the cereal and mix it together.
Add in the rest and mix some more.
Once the mixture has been well blended, press it into the bottom of the prepared baking dish.
In a small microwave safe mixing bowl, add your chocolate chips and butterscotch chips.
Microwave on high for 1 minute and 30 seconds, stopping midway to mix.

Cut and serve. Enjoy!
🍴 Recipe Tips
Cooking Times Vary
With every microwave running at a different wattage, it's important to know your appliance and watch everything. While one microwave might be able to complete this much faster than some, some people may even need to add time to the recipe card below.
Don't Bring the Sugar Mixture to a Boil
The important thing to note is that you do not want to bring the mix to a boil (yes, the microwave can boil things). You simply want the sugar mixture to become dissolved. Your bars will turn out hard instead of soft and chewy if it comes to a boil.
Advanced Preparation Will Make This Run More Smoothly
Make sure that you grease the inside of a 9x13 baking dish well, as this will greatly help with removing the bars later. Also, measure out all of the ingredients and keep them close by before beginning because this recipe will move quickly.
Not All Peanut Butters Work the Same
I do not recommend using natural peanut butter because it is higher in oils and won't turn out as well as traditional Jiff, Skippy, and other peanut butter. We like to use creamy peanut butter for this recipe, but chunky could also work just as fine.
Corn Syrup. You can make these rice krispie scotcheroos without corn syrup! If you can't use corn syrup or don't want to, you can make your own DIY version by mixing together 1 cup of granulated sugar with ¼ cup of water in a small pot. Mix together over medium heat until the sugar has dissolved and the mixture has thickened. Then allow to cool and use as directed.
Looking for some fun inspiration for changing things up a little bit? I've got you covered with some great ideas!
Use Nutella. Swap out half of the requested peanut butter for your favorite jar of Nutella hazelnut spread. So ½ cup of Nutella and ½ cup of peanut butter. Note that using a full cup of Nutella may make these bars "too" sweet. So use caution.
Use sea salt: There's nothing better than a little salt to go with your sweet chocolate. Top these bars off with some flaky sea salt and really elevate the experience.
Add more peanut butter. Can you EVER have too much peanut butter? Add in up to ½ cup more for a softer bar with a stronger peanut butter presence.
Use white chocolate. Replace the semi-sweet chocolate chips with white chocolate! This works well for holidays if you add festive sprinkles! Melting white chocolate can be tricky, so add a tablespoon of shortening or coconut oil to ensure it turns out well the first time.
Use cornflakes instead of crispy cereal. You can use cornflakes (not the frosted kind) to make these cereal bars a little differently if desired. The results are still pretty tasty.
For short term storage, you can place these cooled and cut bars in an airtight container for up to one week at room temperature.
For longer storage, you can place them in an airtight container in the freezer for up to 3 months. I recommend individually wrapping them in plastic wrap if you plan to snack on them one at a time. This is great for adding to lunchboxes!
Scotcheroos are a midwest thing. With scotcheroos being created in Iowa and having branched out over the years to neighboring states, not everyone has gotten to try (or hear about) this tasty bar dessert.
They're a mixture of butterscotch, peanut butter, crispy cereal, and chocolate.
You can easily have gluten free scotcheroos by simply opting for a gluten free cereal. Rice Krispies and a few other kinds of cereal have a certified gluten free label on them, making it easy to spot the safe options in the grocery store.
Make sure to check labels and avoid cross contamination if you're remaining gluten free as a result of an allergy.
Absolutely! You can freeze them prior to cutting so that the chocolate hardens faster, and you can freeze them after they've been cut for a longer storage solution.
I recommend cutting them into desired portion sizes and then wrapping them in plastic wrap inside a Ziploc bag as this will help to keep them fresh as long as possible. It's also easier to grab one to toss in a lunchbox here and there.
If you overcook the sugar and corn syrup mixture, by bringing it to a boil, you will cause your scotcheroos to turn out hard. You want to avoid it if you're looking for tender crispy treats.
With this easy scotcheroos recipe, you are going to love making them in the microwave. This simple recipe is delicious and fun to make!
