Ingredients for butterscotch peanut butter rice krispie treats
Just nine ingredients transform into decadent butterscotch peanut butter rice krispie treats everyone will crave.
| Ingredient | Amount | Notes |
|---|---|---|
| Butterscotch Chips 🍬 | 1 ½ cups | Ensure quality brand for rich flavor |
| Creamy Peanut Butter 🥜 | 1 cup | Natural, unsweetened preferred |
| Mini Marshmallows 🍫 | 6 cups | Standard size, not jumbo |
| Rice Krispies Cereal 🍞 | 6 cups | Original, not honey-nut variety |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for even melting |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality vanilla |
| Kosher Salt 🧂 | ¼ tsp | Fine grain for even distribution |
| Heavy Whipping Cream 🥛 | ¼ cup | Cold for optimal texture |
| Granulated Sugar 🍚 | ¼ cup | Optional for extra sweetness |
The butterscotch chips are non-negotiable for authentic flavor—Trader Joe's or Ghirardelli brands deliver the richest caramel notes. Opt for natural peanut butter (like Smucker's or Jif) to avoid artificial additives that can dull the flavor profile. Mini marshmallows are a must; jumbo marshmallows won't melt evenly and create uneven textures. For the Rice Krispies, stick to the original variety—honey-nut marshmallows would clash with the butterscotch's caramel depth. The butter should be cold and cubed when added to ensure even melting throughout the mixture.
No butterscotch chips? Caramel bits work in a pinch, though the flavor will be slightly less complex. Substitute peanut butter with almond butter for a nutty alternative, though the texture may vary slightly. For a dairy-free option, replace butter with vegan butter and heavy cream with coconut cream. If you prefer a firmer treat, reduce the marshmallows by 1 cup—this cuts down on the gooey texture while keeping the crispy base. The vanilla extract should be pure; imitation extracts often lack the depth needed to complement the butterscotch's richness.
Store finished treats in an airtight container at room temperature for up to 5 days, though they rarely last that long. For longer storage, portion into individual squares and freeze for up to 3 months. The butterscotch chips and peanut butter can be prepped ahead—melt them together in a microwave-safe bowl for 2 minutes in 30-second intervals, stirring between each interval. This ensures even melting without burning. The heavy cream should be whipped lightly before folding in to maintain the treat's signature creaminess.

Step-by-step instructions for butterscotch peanut butter rice krispie treats
Here's the method to create decadent, nutty-sweet treats with perfect texture every time.
Melt Butter and Cream Together
In a large, heavy-bottomed saucepan, combine the 0.5 cup unsalted butter and 0.25 cup heavy whipping cream over medium-low heat. Let the mixture melt slowly, stirring occasionally with a silicone spatula until completely smooth and glossy. This gradual melting prevents burning and ensures even texture throughout.
Watch for small bubbles forming around the edges—this indicates the butter has fully melted. Remove the pan from heat once it reaches a gentle simmer, then stir in the 1 tsp vanilla extract and 0.25 tsp kosher salt. The vanilla will infuse its aroma into the warm mixture, while the salt balances the sweetness. Keep this base warm but not boiling; you'll be adding delicate marshmallows next.
Add Marshmallows and Stir Constantly
Working quickly, add the 6 cups mini marshmallows all at once to the warm butter mixture. Immediately begin stirring vigorously with a wooden spoon to prevent the marshmallows from sticking to the bottom. You'll see them begin to soften and clump together within 1-2 minutes of continuous stirring.
This is where attention matters most—if the marshmallows brown too quickly, remove the pan from heat temporarily. You're aiming for a smooth, creamy consistency where the marshmallows have fully melted but haven't caramelized. The mixture should look like thick, glossy pudding rather than clumpy or grainy.
Incorporate Peanut Butter and Butterscotch Chips
Reduce heat to low and stir in the 1 cup creamy peanut butter until completely smooth. The peanut butter will thicken the mixture significantly, so keep stirring until fully incorporated—you should see no streaks of peanut butter remaining. Then add the 1.5 cups butterscotch chips and the 0.25 cup granulated sugar (if using), stirring until evenly distributed.
Here's the thing—if the mixture looks too thick, you can gently warm it for 10-15 seconds to help it flow more easily. The butterscotch chips will melt slightly, creating pockets of rich butterscotch flavor throughout. This is the moment that matters: the peanut butter and butterscotch chips should be completely dissolved for the best texture.
Combine with Rice Krispies Cereal
Transfer the warm mixture to a large mixing bowl. Using a silicone spatula, gently fold in the 6 cups Rice Krispies Cereal until fully coated. Work quickly but carefully—you want each cereal piece to be lightly dusted with the peanut butter mixture without becoming soggy. If the mixture starts to set too quickly, you can microwave it in 10-second bursts to keep it workable.
Don't press down on the cereal or pack it tightly—this creates dense treats. Instead, gently toss and fold until every piece is uniformly coated. The cereal should look like it's wearing a thin, glossy coating of peanut butter and butterscotch cream.
Press and Cool for Perfect Texture
Lightly grease a 9x13-inch baking dish with cooking spray or butter. Press the cereal mixture firmly and evenly into the pan using a greased spatula or your hands (lightly oiled with butter). Press down until the treats reach the edges of the pan, creating a smooth, even surface. The mixture will be warm and slightly sticky—this is normal.
Let the treats cool completely at room temperature for 1-2 hours before cutting. This cooling period allows the peanut butter to fully set and the butterscotch flavor to meld. If you're impatient, you can refrigerate for 30 minutes to speed up the process, but don't skip this step entirely—it's what gives these treats their signature texture.
Pro Tips For Making Butterscotch Peanut Butter Rice Krispie Treats
- Melt Butter Slowly: Your first batch taught you this the hard way—boiling butter ruins the butterscotch flavor. Use a heavy-bottomed pot on medium-low heat, stirring constantly until it’s just melted, not bubbling. The butter’s job is to bind, not caramelize.
- Chop Chips First: Skip the "melt and mix" step with butterscotch chips—chop them into quarters before adding. They’ll distribute evenly and melt faster, giving you that rich, gooey texture without clumps. (Yes, even if you’re impatient like me.)
- Watch the Marshmallow Stage: The moment the marshmallows hit the pot, they’ll look underdone—don’t panic. Keep stirring until the mixture thickens enough to coat the back of a spoon, then add the Rice Krispies. Overmixing here makes gummy treats; stop when it’s glossy, not sticky.
- Peanut Butter Matters: Not all peanut butter plays nice—use a smooth, high-fat brand (like Jif or Skippy) for the best texture. If yours is too thick, microwave it for 10 seconds to loosen, but don’t skip this step or your treats turn dense. (Your future self will notice.)
Creative variations of this recipe
Spicy Peanut Butter Twist
Add a kick by mixing in 1 teaspoon of cayenne pepper or ½ teaspoon of chili powder with the peanut butter before combining with the marshmallow mixture.
For a smoother heat, I recommend Penzeys Spicy Peanut Butter—it’s already infused with a hint of cayenne, so just use ½ cup instead of the full amount. This variation works especially well if you’re serving these treats to adults who enjoy a little spice with their sweetness. 🌶️
Chocolate-Dipped Edges
For a decadent upgrade, dip the edges of each square in melted chocolate (either dark, milk, or white) after cutting. Use a double boiler to melt ½ cup chocolate chips with 1 teaspoon coconut oil for a glossy finish.
Let the chocolate harden slightly before serving—this creates a beautiful contrast against the butterscotch and peanut butter. Pro tip: Use a paintbrush for precise drizzling along the edges.
White Chocolate Swirl
Fold ½ cup white chocolate chips into the marshmallow mixture after adding the peanut butter and butterscotch chips. Then, use a spoon or skewer to swirl the white chocolate through the cereal mixture before pressing into the pan.
The white chocolate will melt slightly and create marbled streaks throughout each square. For extra richness, I like to use Ghirardelli White Chocolate Baking Bars—they melt beautifully and add a creamy texture. ✨
Caramel Drizzle Topping
After pressing the treats into the pan, let them cool for 30 minutes, then drizzle ½ cup caramel sauce (store-bought or homemade) over the top in a zigzag pattern. Use a piping bag or a spoon to create an even layer.
For a professional touch, sprinkle crushed peanuts or sea salt flakes on top before the caramel sets. This adds a salty-sweet contrast that elevates the butterscotch flavor.
Nut-Free Option
Skip the peanut butter entirely and replace it with ½ cup sunflower seed butter (like SunButter) for a nut-free version. Sunflower seed butter has a similar creamy texture and pairs beautifully with butterscotch.
For extra crunch, fold in ½ cup crushed graham crackers or pumpkin seeds into the cereal mixture before pressing. This variation is perfect for those with nut allergies or dietary restrictions. 💛
Seasonal Citrus Twist
Brighten up the flavor profile by adding 1 teaspoon of orange zest and 1 tablespoon of orange juice to the marshmallow mixture. The citrus cuts through the richness of the butterscotch and peanut butter, making these treats feel fresh and seasonal.
For a festive touch, I like to add freeze-dried orange pieces (about ¼ cup) to the cereal mixture before pressing. This works especially well in fall or winter when you want a little holiday cheer. 🍊

Frequently asked questions
Why do my butterscotch peanut butter treats turn out too sticky?
The marshmallows might not have melted completely or the peanut butter was too cold. Always stir constantly when melting marshmallows and ensure your peanut butter is at room temperature before mixing. If the mixture seems too thick, gently warm it in 10-second microwave bursts while stirring. Pressing too firmly can also create stickiness—use light pressure and let them cool fully before cutting.
Can I make these treats without a baking dish? Press the mixture into a greased 8x8-inch pan or shape into small balls for individual treats. For a fun twist, use silicone molds or line a baking sheet with parchment paper and form into bars. Just
How do I store these treats without them getting soggy?
Store in an airtight container at room temperature for up to 5 days. For longer storage, wrap individually in plastic wrap or place in a freezer bag for up to 3 months. Avoid refrigerating unless necessary—condensation can make them damp. The peanut butter and butterscotch chips keep best at room temperature anyway.
What's the best way to cut these treats for clean edges?
Use a hot knife for perfectly clean cuts. Dip your knife in hot water, wipe dry, then cut through the treats. This prevents sticking and creates sharp edges. For extra precision, chill the treats for 10 minutes before cutting—this helps them hold their shape better. A 9x13-inch pan makes cutting easier with its standard grid pattern.
Can I use powdered peanut butter instead of creamy?
Not recommended—powdered peanut butter lacks the creamy texture and richness you need for these treats. If you must substitute, use ½ cup creamy peanut butter plus ¼ cup powdered peanut butter**> mixed with 1 tablespoon milk to thin it out. The flavor will be slightly different but still delicious. For best results, stick with 100% creamy peanut butter—it's worth the difference!
