This butterscotch peanut butter Rice Krispie treats recipe transforms a classic snack into a decadent dessert with rich, caramelized butterscotch and creamy peanut butter swirled throughout.
The secret lies in melting the marshmallows just until they're smooth, then folding in the cereal while the mixture is still warm—this ensures each crispy cluster gets perfectly coated in that nutty-sweet sauce.
Every bite delivers a perfect balance of crunchy Rice Krispies, gooey marshmallow, and pockets of buttery peanut butter and butterscotch chips.
What sets these apart is the depth of flavor: the peanut butter adds richness while the butterscotch chips create pockets of caramelized sweetness that melt into the warm cereal.
Pressed into a pan and cooled just enough to hold its shape, these treats cut cleanly into perfectly square pieces with golden edges. The texture is a satisfying contrast—crispy on the outside, soft and melty inside—making them irresistible for parties, potlucks, or a special dessert at home.
Ingredients for butterscotch peanut butter rice krispie treats
Six crispy cups of cereal, caramelized butterscotch, and creamy peanut butter—all you need for these decadent treats.
| Ingredient | Amount | Notes |
|---|---|---|
| Rice Krispies Cereal 🍞 | 6 cups | Original flavor preferred |
| Large Marshmallows 🍬 | 12 oz | Mini marshmallows work too |
| Creamy Peanut Butter 🥜 | 1 cup | Natural or regular preferred |

| Vanilla Extract 🌿 | 1 tsp | Pure vanilla preferred |
| Salted Peanuts 🥜 | ½ cup | Chopped for texture |
| Granulated Sugar 🍚 | ¼ cup | Lightly toasted for depth |

The peanut butter is non-negotiable here—natural or creamy both work, but avoid powdered peanut butter. Store-brand jars are just as good as name brands, so don't overthink it. For butterscotch chips, Trader Joe's has the best quality for this recipe, but any brand works if you chop them small. The marshmallows? Mini marshmallows save time, but classic large ones give that nostalgic texture. Toast the sugar lightly in a dry pan for 30 seconds—just until fragrant—this adds depth without burning. And if you're short on time, microwave the butter 40 seconds to melt it without a saucepan.
No peanut butter? Sunflower seed butter works in a pinch, though the flavor will differ. Short on butterscotch chips? Substitute caramel bits or even chopped toffee bits—just know the texture will vary. The peanuts add crunch, but if you're nut-free, skip them or use seeds like pumpkin or sunflower. For extra richness, swap half the marshmallows for white chocolate chips—they melt beautifully into the mix. And if your cereal is stale, toast it lightly in a dry skillet to revive the crunch. The key is keeping everything warm when combining so the cereal gets fully coated.
These treats hold for 5 days in an airtight container, but honestly, they won’t last that long. Press them into a greased 9x13-inch pan for clean slices, or shape into balls for a rustic look. For extra shine, brush the top with melted butter before cooling. Store leftovers at room temperature—they keep surprisingly well, though they soften slightly over time. Freeze for up to 3 months if you’re making a big batch for parties. Just let them sit at room temp for 10 minutes before serving—they’re best at room temperature.

Step-by-step instructions for butterscotch peanut butter Rice Krispie treats
This method delivers perfectly crispy clusters with rich peanut butter and butterscotch flavor in every bite.
Melt Butter and Peanut Butter Together
In a large microwave-safe bowl, combine the 0.5 cup unsalted butter (cut into small cubes) and the 1 cup creamy peanut butter. Microwave in 30-second intervals, stirring between each, until completely melted and smooth. You're looking for a uniform consistency—no lumps should remain in the mixture. This step ensures the peanut butter fully incorporates with the butter, creating a cohesive base for your treats.
I like to use a rubber spatula here to scrape along the sides of the bowl and ensure everything melts evenly. If you notice any separation or graininess, stir more vigorously for another 10-15 seconds between microwave bursts. The mixture should be warm but not hot to the touch when finished.
Add Marshmallows and Butterscotch Chips
Remove the melted butter-peanut butter mixture from the microwave and immediately add the 12 oz large marshmallows and 1.5 cups butterscotch chips. Stir vigorously with a wooden spoon or rubber spatula until the marshmallows are completely melted and fully incorporated. You'll know it's ready when the mixture looks glossy and smooth, with no visible marshmallow chunks.
This is where the magic happens—the butterscotch chips add that signature caramelized flavor while the marshmallows create that signature chewy texture. If you notice any unmelted marshmallow pieces after 1-2 minutes of stirring, microwave the mixture in 10-second bursts until fully melted. Work quickly to prevent the mixture from setting.
Incorporate Remaining Ingredients
Stir in the 0.25 cup granulated sugar, 1 tsp vanilla extract, and 0.25 cup heavy whipping cream. Mix until fully combined, scraping the bottom and sides of the bowl to ensure all ingredients are evenly distributed. The sugar will help balance the richness of the peanut butter and butter, while the vanilla extract adds depth of flavor. The heavy whipping cream adds a luxurious creaminess that ties everything together.
Next, fold in the 0.5 cup chopped salted peanuts using a spatula. Be gentle to avoid breaking the peanuts into tiny pieces—you want them to maintain their texture for that satisfying crunch in every bite. The salted peanuts add a perfect contrast to the sweet butterscotch and peanut butter flavors.
Prepare the Pan and Assemble
Lightly grease a 9x13-inch baking pan with 1 tbsp vegetable oil, making sure to coat the bottom and sides evenly. This prevents the treats from sticking and makes for easy removal later. Spread the mixture into the prepared pan using the spatula, pressing down gently and evenly to create a uniform layer. You want the surface to be smooth but not compacted—just firm enough to hold its shape when cut.
Sprinkle the 0.25 tsp sea salt evenly over the top of the mixture. This finishing touch enhances all the sweet flavors and adds a subtle crunch. Let the treats set in the pan at room temperature for 1-2 hours before cutting into squares. The longer they set, the more crispy and firm they'll become, making them easier to handle and serve.
Cut and Serve
Once the treats have fully set, use a sharp knife to cut them into 48 small squares (about 1.5 inches per side). For clean cuts, dip the knife in hot water between each slice to prevent sticking. The treats will be firm enough to hold their shape but still soft enough to enjoy immediately. If they seem too soft, let them rest at room temperature for another 10-15 minutes before serving.
Store any leftovers in an airtight container at room temperature for up to 5 days, though I doubt they'll last that long. These treats are perfect for parties, potlucks, or just a sweet indulgence anytime. The combination of butterscotch, peanut butter, and salted peanuts creates a flavor profile that's both nostalgic and irresistibly delicious.
Pro Tips For Making Butterscotch Peanut Butter Rice Krispie Treats
- Melt Butter First: I learned this the hard way—throwing cold butter into the pot with marshmallows just makes a sad, lumpy mess. Melt the butter first over medium heat until it’s fully liquid and foamy, then add the marshmallows. This keeps the mixture smooth and prevents clumping, especially when you’re mixing in peanut butter later.
- Crush Butterscotch Chips: Skip the whole-chips approach unless you want a crunchy surprise in every bite. Roughly chop the butterscotch chips into small pieces before folding them in—this guarantees even distribution and melty pockets of caramelized flavor throughout. (Yes, even if you’re impatient like me, take the 30 seconds to do this.)
- Mix Over Low Heat: High heat turns marshmallows into a sticky, burnt nightmare faster than you can say “disaster.” Once the butter and marshmallows are melted, drop the heat to low and stir constantly until it’s fully combined—this keeps the peanut butter from separating and the butterscotch from burning. Sounds weird, but it works.
- Press While Warm: I used to let the treats cool completely before pressing them into pans, and they’d always crack or lose shape. Press them into a greased 9x13-inch pan while still warm (but not dripping)—this locks in the gooey texture and makes slicing clean cuts a breeze. (Your future self will thank you.)
Wine and beer pairings for this butterscotch peanut butter rice krispie treats
Sweet Wine Pairings
A Moscato d'Asti from Italy is my go-to wine for these treats—its light, bubbly sweetness and hints of peach and apricot complement the butterscotch and peanut butter beautifully.
The effervescence cuts through the richness, cleansing your palate between bites. Look for a bottle with 5-6% alcohol to balance the dessert's intensity. 🍷
Rich Dessert Ports
For a more decadent pairing, try a Ruby Port or Tawny Port with 10-20 years of aging. The nutty, caramelized notes in aged Tawny Port mirror the butterscotch flavors, while the slight bitterness in Ruby Port creates a perfect contrast. Serve slightly chilled to enhance the dessert's creamy texture.
Creamy Beer Options
A Belgian-style Witbier like Hoegaarden adds a refreshing twist with its citrusy notes and subtle spice. The light effervescence balances the richness of the peanut butter, while the coriander hints complement the butterscotch.
For a bolder option, try a honey brown ale—the caramel malt notes enhance the dessert's sweetness. 🍺
Coffee Pairing
If you prefer a non-alcoholic option, a strong espresso or cold brew works wonderfully. The bitterness of the coffee enhances the sweetness of the treats, creating a perfect balance. For an extra touch, drizzle a bit of vanilla syrup over the coffee to mirror the vanilla in the recipe.
Spiced Cider
For a cozy, seasonal pairing, serve with spiced apple cider—warm it with a cinnamon stick and a pinch of cloves. The warm spices complement the peanut butter and butterscotch while adding a comforting touch. This pairing is especially perfect for fall gatherings or holiday celebrations.

Frequently asked questions
Can I make these treats without peanut butter?
Yes! For a nut-free version, substitute 1 cup sunflower seed butter or 1 cup almond butter (though the flavor will differ). You can also omit the peanut butter entirely and add 1 extra cup of butterscotch chips for intensified caramel flavor. The treats will still hold together, though the texture will be slightly softer.
Why do my butterscotch peanut butter treats turn out too soft?
This usually happens if the mixture cools too quickly or if you didn't press it firmly enough into the pan. Let the treats set at room temperature for the full 1-2 hours before cutting. For extra firmness, chill the pan in the refrigerator for 30 minutes before slicing. Also, ensure your marshmallows are fully melted—any unmelted pieces create weak spots.
How do I get clean cuts when slicing?
Use a sharp knife and dip it in hot water between each cut to prevent sticking. Press down firmly but evenly to create clean lines. For even better results, chill the treats for 10 minutes in the freezer before cutting—this makes them firmer and easier to slice into perfect squares. A 9x13-inch pan gives the best uniform cuts, but you can also shape the mixture into balls for a rustic look.
Can I make these treats ahead of time?
These treats keep well for 5 days in an airtight container at room temperature. For longer storage, freeze them for up to 3 months. Let them sit at room temperature for 10-15 minutes before serving to restore their soft, melty texture. They're perfect for meal prep or gifting—just wrap individual squares in parchment paper for a professional touch.
What’s the best way to store leftovers?
Store in an airtight container at room temperature to maintain their texture. If your kitchen is very warm, refrigerate them for up to 3 days, but bring them to room temperature before serving. Avoid freezing if you can—thawed treats can become slightly grainy. For extra freshness, place a slice of bread in the container to absorb moisture and keep them crispy.
