Ingredients You’ll Need
What makes Fluffernutter Rice Krispie Treats so special is just how simple (yet irresistible) the ingredients are! Each one brings its own unique flavor or texture—the crispy crunch, the marshmallow stretch, and that dreamy peanut buttery finish all blend together for snacking bliss.
- Rice Krispies cereal: The classic crispy base gives these bars their irresistible crunch and keeps every bite feeling light.
- Unsalted butter: Melted butter lends richness and a subtle savory note that stops the bars from being too sweet.
- Mini marshmallows: Divided up between melting and mix-in, these create the gooey, pull-apart texture everyone loves.
- Creamy peanut butter: Delivers that signature “fluffernutter” flavor with silky smoothness in every layer (use classic creamy, not natural, for best results).
- Pinch of salt (optional): If your peanut butter isn’t already salted, just a dash balances the sweetness perfectly.
- Marshmallow Fluff: The game-changer—folded in with the cereal for extra ribbons of marshmallow with every slice.
Variations
Part of the fun with Fluffernutter Rice Krispie Treats is that you can totally mix things up! Feel free to get creative—these bars are wildly forgiving and easily adapt to whatever peanut-buttery, nutty, or chocolatey twist you’re craving.
- Swirl in Chocolate: Drizzle melted chocolate (or fold in chocolate chips) for a “choco-fluffernutter” upgrade that will satisfy any sweet tooth.
- Try Different Nut Butters: Almond or cashew butter can swap in for the peanut butter for a new nutty flavor spin—sunflower seed butter works for a nut-free treat!
- Add Crunch: Fold in roasted peanuts, pretzel pieces, or toffee bits for pops of texture and bursts of salty-sweet goodness.
- Make Them Vegan: Simply use vegan butter, vegan marshmallows, and a vegan marshmallow cream, and you’ve got plant-based treats for everyone.
How to Make Fluffernutter Rice Krispie Treats
Step 1: Prep Your Pan and Cereal
Line your 9×13-inch pan with parchment so that the edges hang over for easy lifting, and give it a little spritz with nonstick spray. Go ahead and measure your Rice Krispies into a big mixing bowl—you’ll want everything ready because this recipe comes together fast!
Step 2: Melt the Butter and Marshmallows
In a medium saucepan, melt the butter gently over low heat (don’t rush it). Add 4 cups of your mini marshmallows, stirring until they’re mostly melted and smooth—it’s actually perfect if there are a few unmelted bits left for added chew.
Step 3: Stir in Peanut Butter and Salt
With the heat off, add peanut butter to your melted marshmallow mix and stir until it’s combined and glossy. This is also the moment to toss in a pinch of salt if your peanut butter is unsalted—don’t skip it!
Step 4: Mix Everything Together
Scrape the peanut butter mixture over your Rice Krispies, then add the Marshmallow Fluff and the remaining 2 cups of mini marshmallows. Quickly, but gently, fold everything together until the cereal is mostly coated and you spy ribbons of gooey Fluff throughout.
Step 5: Press & Set
Transfer the mixture to your prepared pan. Use another pan, a greased spatula, or parchment under your hands to gently press the mix into an even layer—don’t pack it down too much or you’ll lose that dreamy fluffiness. Let them set (no need to refrigerate!) for at least 15 minutes before slicing your giant squares of Fluffernutter Rice Krispie Treats.
Pro Tips for Making Fluffernutter Rice Krispie Treats
- Low & Slow is Key: Always melt your butter and marshmallows over low heat to avoid burning and to keep the finished bars ultra gooey.
- Don’t Overmix: When folding in Marshmallow Fluff and whole mini marshmallows, just mix until combined so you keep pockets of gooey goodness.
- Use Classic Creamy Peanut Butter: Skip “natural” peanut butters, which can separate and leave bars greasy or crumbly—a classic creamy type will give you the perfect consistency.
- Gentle Press: Don’t smash the bars into the pan—press just enough to flatten, so your Fluffernutter Rice Krispie Treats stay soft, light, and chewy.
How to Serve Fluffernutter Rice Krispie Treats
Garnishes
Dress them up by drizzling melted chocolate or extra peanut butter on top, then sprinkle a little flaked sea salt or a handful of chopped roasted peanuts for added crunch—even tiny mini marshmallows stuck on for “clouds” take them over the top!
Side Dishes
Pair your Fluffernutter Rice Krispie Treats with a cold glass of milk, a mug of hot cocoa, or next to fresh fruit like sliced strawberries or banana for a fun “PB&J” peanut butter sandwich-inspired experience.
Creative Ways to Present
For parties, cut the bars into mini squares and skewer them on lollipop sticks, or layer them in jars with extra Fluff and peanut butter swirls for a whimsical dessert parfait. Wrap individual bars in wax paper and tie with twine for playful lunchbox treats!
Make Ahead and Storage
Storing Leftovers
Fluffernutter Rice Krispie Treats keep best at room temperature—just store them in an airtight container lined with parchment or wax paper, and they’ll stay soft and chewy for up to 3 days (if they last that long!).
Freezing
These bars freeze surprisingly well! Lay cut squares between sheets of parchment, pop them in a freezer-safe bag or container, and freeze up to 2 months. Thaw at room temperature before serving for that gooey, sticky, freshly-made feel.
Reheating
If you love your treats extra gooey, zap a single bar in the microwave for 5–8 seconds. It’ll taste like it just came together—caution, things can get sticky (in the best way)!
FAQs
-
Can I use marshmallow creme instead of Marshmallow Fluff?
Absolutely! Marshmallow Fluff and marshmallow creme are nearly interchangeable in these treats, so either will bring those gooey swirls—just go with whichever is easiest to find in your area.
-
What’s the best peanut butter to use for Fluffernutter Rice Krispie Treats?
Stick to classic creamy peanut butter for the smoothest, richest bars—“natural” peanut butters can separate and won’t set as evenly, so you’ll get the best texture from regular peanut butter.
-
Why are my treats hard or dry?
This usually happens if the marshmallows or butter were cooked over too high heat (or if the mixture was pressed too firmly into the pan). Always melt gently and don’t pack the mixture too tight for soft, pillowy bars!
-
Can I make Fluffernutter Rice Krispie Treats ahead for a party?
Definitely! These treats are perfect made a day in advance. Just store them airtight on the counter and slice them up right before serving for maximum gooeyness and fresh flavor.
