Ingredients You’ll Need

These treats require only a handful of pantry staples, but each ingredient is a total star—contributing to the signature taste, irresistible texture, and all-around fun of Fluffernutter Rice Krispie Treats. Here’s what makes each one essential:

• Unsalted Butter: Adds buttery richness and ensures the base is perfectly chewy and luscious.
• Mini Marshmallows: Creates the iconic gooey, sweet base and holds everything together.
• Creamy Peanut Butter: Delivers that classic fluffy nuttiness and complements the marshmallow beautifully.
• Rice Krispies Cereal: Provides the trademark crunch and structure that makes these bars so satisfying.
• Marshmallow Creme (Fluff): Adds dreamy swirls for extra visual flair and a cloud-like texture.
• Vanilla Extract: Rounds out the flavors with a subtle warmth and depth.
• Pinch of Salt: Enhances all the sweet notes and balances the flavors perfectly.

How to Make Fluffernutter Rice Krispie Treats

Step 1: Prep Your Pan

Begin by greasing a 9×13-inch baking dish with unsalted butter or a spritz of nonstick cooking spray. This simple step guarantees that your Fluffernutter Rice Krispie Treats will lift out with ease, leaving every delicious swirl intact. Set the pan aside and get ready for some marshmallow magic.

Step 2: Melt the Butter and Marshmallows

In a large, heavy-bottomed saucepan set over medium heat, melt the butter completely. Add in the mini marshmallows and stir constantly until they’re entirely melted and silky smooth. Watch closely—nothing says “yum” more than that glossy, sticky base forming right before your eyes!

Step 3: Stir in Peanut Butter, Vanilla, and Salt

Now’s the time to ramp up the flavor! Mix in the creamy peanut butter, vanilla extract, and a pinch of salt. Stir until every ribbon of peanut butter is meltingly incorporated, creating a dreamy, nutty foundation for these classic bars.

Step 4: Fold in the Rice Krispies Cereal

Turn off the heat and immediately dump in your Rice Krispies cereal. Using a sturdy spatula, fold gently but thoroughly. You want every little puff to get a glossy coat of that marshmallow peanut butter mixture, but don’t over-mix to keep them extra airy.

Step 5: Swirl in the Marshmallow Creme

Let your mixture cool just slightly (1–2 minutes is perfect), then drop spoonfuls of marshmallow creme over the top. Gently fold it in a couple of times to create gorgeous, fluffy swirls. Stop before it’s fully mixed for that signature “fluffernutter” look and texture in every bite.

Step 6: Press Into the Pan and Cool

Spoon the mixture into your prepared pan. Lightly press it down with a buttered spatula or piece of wax paper—think firm, but not packed down, to keep things tender. Let your Fluffernutter Rice Krispie Treats cool completely at room temperature. Once cooled, slice into squares and prepare to swoon.

How to Serve Fluffernutter Rice Krispie Treats

Garnishes

Add even more mouthwatering flair by drizzling a bit of melted peanut butter over the top before serving. For crunch lovers, a scattering of crushed, salted peanuts or a sprinkle of mini marshmallows makes every bar look party-ready and taste extra special.

Side Dishes

Balance the sweetness with a cold glass of milk, a mug of hot cocoa, or even a tart berry salad. If you’re turning these Fluffernutter Rice Krispie Treats into party fare, serve with fresh fruit skewers or cheese platters for a fun contrast of flavors.

Creative Ways to Present

Cut your treats into mini bites for a dessert board, or use shaped cookie cutters for lunchbox surprises. Stack them and wrap with parchment and twine for a nostalgic bake sale vibe, or skewer cubes for marshmallow treat kebabs at your next celebration!

Make Ahead and Storage

Storing Leftovers

Keep your Fluffernutter Rice Krispie Treats fresh by storing them in an airtight container at room temperature for up to 3 days. Place sheets of wax or parchment paper between layers to prevent sticking—and to keep those beautiful swirls intact.

Freezing

If you want to stash some for later, place cut squares in a single layer on a baking sheet and freeze. Once solid, transfer the bars to a freezer-safe container or bag, with parchment between layers. They’ll keep for up to 2 months; just thaw at room temp when a sweet craving hits.

Reheating

These treats are best enjoyed at room temperature, but if they’re a bit firm from storage or you prefer the extra gooey factor, microwave individual squares for about 5–10 seconds. The marshmallow will soften and the whole bite will taste freshly made.

FAQs

Can I use chunky peanut butter instead of creamy?

Absolutely! Chunky peanut butter will add extra nutty pieces and even more texture. Just be aware that it may not blend as smoothly as creamy, so your Fluffernutter Rice Krispie Treats might have a slightly different look but loads of big peanut flavor.

Can I substitute a different cereal?

You can try! While Rice Krispies keep things light and classic, other puffed rice cereals work well. Even crispy corn or wheat squares can add their own twist. Just aim for a light, neutral flavor to let the fluffernutter combo shine.

How do I avoid sticking when pressing the mixture into the pan?

Grease your spatula or use a piece of wax paper sprayed lightly with nonstick spray to press the mixture down without mess. This helps keep all the Fluffernutter Rice Krispie Treats’ gooey goodness in the pan instead of on your hands.

Are these treats gluten free?

The basic ingredients are gluten free, but always check your cereal packaging to ensure it hasn’t been processed with gluten-containing products. Marshmallow and peanut butter brands can vary, so double-check if you need these treats to be celiac safe.

Can I double this recipe?

Definitely! Just grab a larger pan or prepare two 9×13-inch pans. Fluffernutter Rice Krispie Treats are fantastic for a crowd and double every bit as easily as the original without sacrificing texture or swirl magic.
