Ingredients for reese's chocolate peanut butter rice krispie treats
Five simple ingredients transform into nostalgic crunchy clusters with gooey melty magic—perfect for any occasion.
| Ingredient | Amount | Notes |
|---|---|---|
| Butter 🧈 | 1 cup | Unsalted, melted completely |
| Peanut Butter 🥜 | 1 cup | Creamy, natural style preferred |
| Mini Marshmallows 🍫 | 6 cups | Classic or jumbo size |
| Rice Krispies Cereal 🍞 | 8 cups | Original flavor, crushed lightly |
| Reese's Peanut Butter Cups 🍫 | 1 ½ cups | Chopped into small pieces |
| Vanilla Extract 🌿 | 1 tsp | Pure vanilla for depth |
| Salt 🧂 | ½ tsp | Fine sea salt for balance |
The Reese's cups are the star here—Hershey's Classic is my go-to, but any brand works. Chop them into small, even pieces so they melt beautifully throughout. For the peanut butter, Jif Natural or Skippy Creamy both work perfectly—just avoid the chunky kind unless you want texture surprises. Butter matters too: Plugrá or Land O'Lakes unsalted melt smoothly without any graininess. If you're feeling fancy, grab a silicon spatula for easy scraping—trust me, it's worth the extra minute.
No Reese's cups? Crushed peanut butter cups or even chopped peanut butter candy bars get you close. Running low on marshmallows? Mini marshmallows from Trader Joe's are my secret weapon—they're slightly larger and melt perfectly. For an extra boost, add white chocolate chips or chopped peanuts to the mix. And if you're worried about the treats sticking, line your pan with parchment paper—it's a game-changer. The cereal? Original Rice Krispies are a must—no substitutions here, folks.
These treats stay fresh for 5-7 days in an airtight container at room temperature, but they're even better the next day once everything melts together. For longer storage, freeze them for up to 3 months—just let them sit at room temperature for 10 minutes before serving. Pro tip: Portion into individual squares before they fully set so you can grab one whenever the craving hits. They're perfect for holiday gifting too—just wrap them in cellophane and tie with a ribbon.

Step-by-step instructions for Reese's chocolate peanut butter Rice Krispie treats
Here's how to create these decadent treats with perfect texture and flavor balance every time.
Melt the Butter and Peanut Butter Together
In a large microwave-safe bowl, combine the 1 cup unsalted butter and 1 cup creamy peanut butter. Microwave on high for 1 minute, then stir vigorously with a wooden spoon to ensure even melting. Return to the microwave for 30-second intervals until completely smooth and glossy—this should take about 2-3 minutes total. The mixture should be silky and free of any lumps.
I like to test the temperature by dripping a small amount onto a plate—it should feel warm to the touch but not hot enough to burn your finger. This gentle heat helps the peanut butter emulsify perfectly with the butter, creating a rich base for your treats. If you prefer stovetop melting, use a double boiler over low heat and stir constantly until smooth.
Incorporate Vanilla and Salt
Remove the melted mixture from the microwave and let it cool slightly for 1-2 minutes—it should be warm but not hot. Add the 1 teaspoon vanilla extract and ½ teaspoon fine sea salt, then whisk vigorously for 20-30 seconds until fully combined. The salt enhances all the peanut flavors while balancing the sweetness, and the vanilla adds depth that makes these treats taste like a gourmet dessert.
Here's the thing—don't rush this step. The vanilla needs time to disperse completely, and the salt should dissolve evenly. If you taste it now, you'll notice how the peanut butter's natural sweetness is already developing. This is where the magic begins, so take your time getting it right.
Melt the Marshmallows and Reese's Pieces
Add the 6 cups mini marshmallows and 1.5 cups chopped Reese's peanut butter cups to the peanut butter mixture. Microwave again on high for 1 minute, then stir thoroughly. Return to the microwave for 30-second intervals until the marshmallows are completely melted and the Reese's pieces are fully incorporated—this should take about 2-3 minutes total. The mixture should look like a thick, glossy caramel with visible peanut butter swirls.
Watch carefully as you microwave—you want everything fully melted but not scorched. If the mixture starts to look too dry or grainy, add 1 tablespoon water and stir well. The goal is a smooth, pourable consistency that will coat the Rice Krispies perfectly. This is the moment that matters: when you lift the spoon, the mixture should flow like warm honey.
Combine with Rice Krispies
Immediately add the 8 cups lightly crushed Rice Krispies cereal to the melted mixture. Using a wooden spoon or rubber spatula, fold gently but thoroughly for 1-2 minutes until every cereal piece is coated. Work quickly—the mixture will start to set as it cools. I press down gently on the mixture to help the cereal absorb the peanut butter mixture evenly, creating those perfect crunchy clusters.
Don't be tempted to overmix—you're looking for a texture where each Rice Krispie is lightly coated rather than fully submerged. The treats should hold their shape when pressed together, but still have that signature Rice Krispie treat crunch. If the mixture feels too sticky, add 1-2 more cups of crushed cereal to absorb the excess moisture.
Press and Cool for Perfect Texture
Quickly transfer the mixture to a 9x13-inch baking dish lined with parchment paper. Press down firmly and evenly using a greased spatula or the bottom of a glass measuring cup. You want to create an even layer that's about ½-inch thick—this ensures consistent texture throughout. For extra decadence, I like to sprinkle additional chopped Reese's pieces on top before pressing.
Let the treats cool completely at room temperature for 1-2 hours before cutting. This resting time is crucial—it allows the peanut butter to firm up just enough to hold its shape when sliced, while maintaining that signature gooey center. If you're impatient, chill in the refrigerator for 30 minutes, but don't skip this step entirely or your treats will be too soft to cut cleanly.
Pro Tips For Making Reese'S Chocolate Peanut Butter Rice Krispie Treats
- Melt Butter First: I learned this the hard way—don’t just toss cold butter in with the peanut butter and marshmallows. Melt the butter first over low heat until it’s fully liquid and just starting to turn golden. This keeps your mixture smooth and prevents those weird butter lumps that ruin the texture.
- Crush Reese’s Cups: Skip the whole peanut butter cups if you’re in a hurry, but if you want that real Reese’s flavor to shine, crush the cups into small chunks before mixing. I use a rolling pin or a heavy pan—just a few hard smashes does the trick. This distributes the peanut butter and chocolate more evenly instead of hiding as big, melty pockets.
- Watch the Marshmallow Heat: High heat turns marshmallows into sad, gooey glue. Once the butter, peanut butter, and marshmallows hit the pan, keep the heat at a gentle simmer—low enough that you can hold your hand a few inches above it without feeling the heat. Stir constantly, or you’ll end up with burnt edges and undercooked centers.
- Add Rice Krispies Slowly: Dumping all the cereal in at once makes a mess and leads to uneven treats. Instead, fold in the Rice Krispies in two batches, letting the first half soak up the mixture before adding the rest. This guarantees every piece gets coated properly—no dry, crunchless lumps hiding in the middle.
Creative variations of this dish
Peanut Butter Cup Twist
For an extra decadent version, replace ½ cup of the mini marshmallows with ½ cup crushed Reese's peanut butter cups before pressing into the pan. This creates pockets of peanut butter flavor throughout each bite.
I like to pulse the extra cups in a food processor for 10 seconds to get fine, even pieces that melt beautifully. 🥜
White Chocolate Swirl
Add ½ cup white chocolate chips to the melted marshmallow mixture and microwave until fully melted. Then, drizzle ¼ cup melted white chocolate in zigzag patterns over the pressed treats before they fully set.
The contrast of creamy white chocolate against the rich peanut butter is pure magic—plus, it looks stunning when sliced. 🍫
Crunchy Nut Mix-Ins
Fold in ½ cup chopped pecans or peanuts with the Rice Krispies for added texture. Toast the nuts in a dry pan over medium heat for 3-4 minutes until fragrant, then cool completely before mixing.
This adds a satisfying crunch that balances the gooey peanut butter center. For extra flair, sprinkle additional toasted nuts on top before pressing. 🌰
Salted Caramel Version
Swap ½ cup of the peanut butter for ½ cup caramel sauce (I use Smucker's Salted Caramel) and add 1 extra pinch of flaky sea salt (about ¼ teaspoon).
The salty-sweet combination elevates the treats to restaurant-quality dessert status. Drizzle with extra caramel sauce after pressing for a professional finish. 🍯
Mini Marshmallow Clusters
For a fun, handheld version, roll the mixture into 1-inch balls using lightly greased hands (about 1 tablespoon per ball). Place on a parchment-lined tray and flatten slightly with your palm.
Chill for 15 minutes before serving—these bite-sized treats are perfect for parties! For extra flair, roll the balls in crushed pretzels before chilling. 🍬
Hot Fudge Drizzle
After pressing the treats, microwave ½ cup chocolate syrup (like Hershey's Hot Fudge) for 20 seconds until smooth. Drizzle over the set treats and let cool completely.
The fudge adds a glossy finish and extra richness that pairs perfectly with the peanut butter. Use a fork to create decorative swirls before serving. 🍫

Frequently asked questions
Can I make these treats without Reese's peanut butter cups?
Use 1.5 cups crushed peanut butter cups (any brand) or 1 cup creamy peanut butter + ½ cup chocolate chips for a similar effect. For extra richness, swap in white chocolate chips instead of chocolate chips. The key is maintaining the peanut butter flavor profile while keeping the gooey texture.
Why did my treats turn out too sticky or soft?
This usually happens when the mixture cools too slowly or doesn't firm up enough. Always let them cool 1-2 hours at room temperature before cutting—rushing this step makes them too soft. If they're still sticky, chill in the fridge for 30 extra minutes. For next time, try adding 1 extra cup of crushed Rice Krispies to absorb excess moisture.
How do I store these treats for maximum freshness?
Keep them in an airtight container at room temperature for 5-7 days. For longer storage, freeze individual portions for up to 3 months. Let frozen treats sit at room temperature for 10 minutes before serving—they'll taste even better after resting! For gifting, wrap in cellophane and tie with ribbon for a professional touch.
Can I make these treats gluten-free?
Yes! Use gluten-free Rice Krispies cereal (like Quaker's GF version) and check that your peanut butter and Reese's cups are certified gluten-free. The recipe remains exactly the same—just swap the cereal. For extra safety, verify all ingredients in your pantry are GF certified. The texture will be identical once cooled!
What's the best way to cut them for perfect squares?
Use a hot knife (dip in hot water and wipe dry between cuts) for clean edges. Let the treats cool completely first, then cut into 1-inch squares or your preferred size. For decorative shapes, use cookie cutters while the mixture is still warm but firm. The hot knife prevents crumbling and makes serving easier.
