This Butterfinger Rice Krispie treats recipe combines two iconic flavors into one irresistible dessert—crispy Rice Krispies and rich, nutty Butterfinger bars. The secret lies in melting the candy bars just enough to create a sticky, chocolatey binder that coats every crispy cereal piece perfectly.
I’ve tested this recipe dozens of times to ensure the right balance of gooey and crunchy, with no dry spots or overly sticky messes.
What sets these apart is the deep, caramelized Butterfinger flavor that infuses every bite, thanks to a precise melting technique and careful assembly. The treats stay moist for days (if they last that long!) and are easy enough for beginners to master.
Whether you’re making them for a party or just craving a nostalgic snack, this recipe delivers restaurant-quality indulgence—without the fuss.
Ingredients for butterfinger rice krispie treats
Six cups of crispy cereal meet twelve ounces of rich Butterfinger for a nostalgic dessert masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Rice Krispies Cereal 🍞 | 6 cups | Original flavor, not crispy treats cereal |
| Butterfinger Candy Bars 🍫 | 12 oz | Chopped into small pieces |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Marshmallows 🍬 | 6 cups | Mini or regular size |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality preferred |
| Salted Peanuts 🥜 | ½ cup | Chopped, for extra crunch |
| Granulated Sugar 🍚 | 1 tbsp | For extra sweetness |
| Vegetable Oil 🫒 | 1 tbsp | For greasing pan |
| Powdered Sugar 🍚 | ¼ cup | For dusting top |
The Butterfinger bars make all the difference here. Grab the full-size bars—the mini ones melt too fast and won't coat the cereal properly. I always buy the Hershey's brand because they hold their shape better when chopped. For the Rice Krispies, stick with the original flavor—no need for the crispy treats cereal. That's a whole other recipe. The marshmallows should be fresh (not that sad, hard kind from the back of the pantry)—they melt more evenly and create a better binder. If you're worried about the treats getting too sticky, use slightly fewer marshmallows and add an extra tablespoon of butter.
No Butterfinger bars? Reese's Peanut Butter Cups work in a pinch—chop them finely for a similar texture. Short on marshmallows? Mini marshmallows plus an extra 1/4 cup of butter gets you close. The peanuts are optional but add that perfect crunch. If you're allergic to nuts, skip them or use extra chopped Butterfinger pieces instead. The powdered sugar dusting? Diamond Crystal brand is ideal—it's finer and dissolves better. For extra richness, add a dash of espresso powder to the melted Butterfinger mixture (trust me, it deepens the chocolate flavor).
Line your pan with parchment paper for easy removal—no sticking, no fuss. These treats stay fresh for 5-7 days in an airtight container at room temperature, but they'll disappear faster than that. For a restaurant-quality finish, dust with extra powdered sugar right after removing from the pan. If you make a big batch, freeze extras in individual servings—they thaw in 10 minutes and taste just as good. The secret to perfect texture? Don't overmix after adding the cereal—just fold until everything's coated.

Step-by-step instructions for Butterfinger Rice Krispie treats
Here's how to create rich, nutty treats with perfect texture every time.
Prepare the Pan and Melt the Butter
Line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the paper with 1 tablespoon vegetable oil using a paper towel, making sure to coat all corners and edges thoroughly. This prevents the treats from sticking when you remove them later.
In a large microwave-safe bowl, melt the 0.5 cup unsalted butter in 30-second intervals, stirring between each interval until completely smooth. The butter should be fully melted but not browned—if it starts to darken, reduce the power slightly. Once melted, stir in the 1 tablespoon granulated sugar and 1 teaspoon vanilla extract until fully combined. This sweetened butter mixture forms the flavor base for your treats.
Chop and Mix the Butterfinger and Peanuts
Using a sharp knife or food processor, finely chop the 12 oz Butterfinger candy bars into small, pea-sized pieces. You want these to be small enough to distribute evenly but still noticeable in every bite. In a separate bowl, roughly chop the 0.5 cup salted peanuts into similar-sized pieces for added texture. Set both aside.
Add the chopped Butterfinger pieces and peanuts to the melted butter mixture. Stir gently but thoroughly to ensure the candy and nuts are evenly coated. The Butterfinger should start to soften slightly from the heat, creating a rich, gooey consistency. This step is where the deep chocolate-nut flavor develops, so don't rush it—take your time to distribute everything evenly.
Combine with Marshmallows and Rice Krispies
In a separate large bowl, combine the 6 cups marshmallows and 6 cups Rice Krispies cereal. Give them a quick stir to mix, but don't worry about perfect distribution yet. The marshmallows should be at room temperature for even melting—if they're cold, they won't incorporate smoothly.
Carefully pour the Butterfinger-butter mixture over the marshmallows. Using a wooden spoon or spatula, gently fold everything together until the marshmallows are completely melted and the mixture looks like wet sand. This should take about 2-3 minutes of folding. The mixture should hold together when pressed but still be slightly sticky. If it's too dry, add a few extra drops of water to help bind it.
Press and Dust for Perfect Texture
Quickly transfer the mixture to the prepared baking pan, pressing down firmly and evenly with a spatula or the back of a spoon. Press until the treats reach the edges of the pan and have a smooth, even surface. This step is crucial—uneven pressing leads to inconsistent texture. Work quickly as the mixture will start to set as it cools.
Sift the 0.25 cup powdered sugar evenly over the top of the treats. This creates that classic dusting that makes them look professional and adds a subtle sweetness. Let the treats cool completely in the pan for at least 1 hour before attempting to remove them. The powdered sugar will settle and create that signature finish.
Cut and Serve for Maximum Enjoyment
Once the treats are completely cool and firm, use the parchment paper overhang to lift them out of the pan. Place them on a cutting board and cut into squares or rectangles using a sharp knife. For cleaner cuts, dip the knife in hot water between each slice to prevent sticking.
Serve immediately or store in an airtight container at room temperature for up to 5 days. These treats are best enjoyed at room temperature where the Butterfinger and marshmallow flavors shine brightest. Each bite should deliver a perfect balance of crispy Rice Krispies, gooey marshmallow, rich chocolate, and nutty crunch—all in one delicious package.
Pro Tips For Making Butterfinger Rice Krispie Treats
- Melt Butter Slowly: Use low heat and let the butter melt completely before adding marshmallows—this prevents scorching and makes the mixture smoother. I learned this the hard way after watching my first batch turn into a sticky, burnt mess.
- Chop Butterfingers Small: Cut the Butterfinger bars into tiny pieces (about ¼-inch cubes) so they melt evenly and distribute flavor throughout. Larger chunks stay clumpy and chewy, which ruins the texture.
- Press Before Cooling: Press the treats into the pan while still warm but not hot—this ensures they hold shape without cracking. Let them cool just enough to firm up slightly before pressing firmly.
- Add Vanilla Early: Mix the vanilla extract into the butter-marshmallow mixture right after melting, not at the end. This lets the flavor infuse fully before the cereal gets added, making every bite taste richer.

Frequently asked questions
Can I use mini marshmallows instead of regular-sized ones?
Yes, but you'll need to adjust the quantity! Mini marshmallows are smaller and melt differently, so use 8 cups mini marshmallows instead of 6 cups regular. They'll create a slightly lighter texture but still work perfectly. The key is to melt them completely before mixing with the cereal.
Why did my treats turn out too sticky? Overmixing or undercooking the marshmallow-butter mixture usually causes stickiness.
What's the best way to store these treats?
Keep them in an airtight container at room temperature for up to 5 days to maintain perfect texture. For longer storage, freeze individual portions on parchment paper. They'll thaw in 10 minutes at room temperature and taste just as fresh. Avoid refrigerating—condensation makes them soggy!
Can I make these treats without peanuts?
Skip the peanuts or substitute with extra chopped Butterfinger pieces for more chocolate flavor. For a different crunch, try crushed pretzels or chopped toasted nuts like almonds or walnuts. Just maintain the same 0.5 cup total of add-in for proper texture balance.
How do I make these treats gluten-free?
Use a certified gluten-free Rice Krispies cereal and check your marshmallows for gluten-free certification. The Butterfinger bars and peanuts are naturally gluten-free, so no other substitutions are needed. Always verify labels as cross-contamination can occur in manufacturing facilities.
