Why You’ll Love this Fluffernutter Sandwich
This sandwich is what happens when childhood fever dreams meet pantry practicality. No fancy ingredients or culinary techniques here—just spread, stack, maybe sizzle.
- Ridiculously simple to make: You just squish, smear, and stack—then maybe griddle, if you’re feeling bold.
- Satisfyingly sticky and sweet: That marshmallow fluff clings to your soul (and your lips, fair warning).
- Perfect for a kitchen shortcut: No need to preheat the oven, flip anything with precision, or summon patience.
- Grilled option = candy toast: Buttered, golden-brown bread takes this from lunchbox nostalgia to full-blown dessert.
- Nostalgic in the best way: It’s like recess, cartoons, and bare feet in food form.

Ingredient Notes
So few ingredients, yet with so many opportunities to get just-the-right squish and balance. Let’s peek at the cast of characters:
- White bread: Soft and squishy is the goal. Go for the classic stuff—it clings perfectly to gooey fillings and grills like a champ.
- Creamy peanut butter: Smooth and spreadable wins the day here. But if you’re feeling rebellious, crunchy adds some unexpected texture.
- Marshmallow fluff: Sweet, slightly bouncy, and clings like a clumsy hug. Don’t swap it with melted marshmallows—it’s not the same vibe.
- Unsalted butter (optional): For grilled sandwiches, it adds that golden crunch and a little savory balance. Also smells amazing on the skillet.
How To Make This Fluffernutter Sandwich
There’s honestly not much standing between you and the glorious stickiness that is a fluffernutter, which is exactly why I love it. You’re minutes away from gooey bliss.
-
Lay out the bread: Start by plopping all four slices down on a clean surface. Don’t overthink it—we’re not building IKEA furniture, just sandwiches.
-
Spread the peanut butter: Two slices get a generous smear. Like, edge-to-edge generosity. No dry corners allowed. If you’re like me, you might accidentally “taste test” a spoonful or two here.
-
Spread the fluff: Take the other two slices and coat them with marshmallow fluff. It’s clingy, so work gently. If it tries to stick to the knife more than the bread, just relax—you’re bossing it.
-
Sandwich and press: Gently match the fluff sides with the peanut butter sides, and give each one a tiny press so they stick. It should look like soft white pillows full of childhood happiness.
-
Optional: Grill it up: Butter the outsides and toss them in a skillet over medium-low heat for 3 to 4 minutes each side. They’ll turn golden and crispy while the insides melt into pure sweet lava.
Storage Options
Honestly, these fluffernutter sandwiches are at their messiest, gooiest best straight out of your hands. That said, life happens. Maybe you made a couple extra or maybe you like planning ahead like an organized marshmallow wizard.
If you do need to store them, wrap the ungrilled version tightly in plastic or toss each in an airtight container. Pop them in the fridge, and you’ve got about a day or two before the bread starts to feel weirdly damp and the fluff deflates a bit.
Grilled ones? Treat them like you would leftover grilled cheese—wrap in foil and chill, then reheat gently in a skillet over low heat. The microwave works in a pinch, but it softens the crunch, so the texture’s not quite the same.
And yes, people ask… “Can I freeze it?” Technically? Sure. But when it thaws, it’s going to be a bit soggy and the fluff may separate. If you’re thinking long-term marshmallow plans, maybe try something meant for the freezer, like these peanut butter banana ice cream sandwiches.
Variations and Substitutions
You can make tiniest swaps or go full mad-scientist if you’re feeling inspired. The fluffernutter is more flexible than it looks—that white bread is basically a blank canvas.
- Crunchy peanut butter: If texture is your thing, swap the creamy stuff for chunky. Crunch meets goo makes for a party in your molars.
- Add sliced banana: Classic Elvis move. It softens into the sandwich and adds natural sweetness while pretending to be a fruit serving.
- Chocolate hazelnut spread instead of PB: Yep. Decadence incoming. Your inner child and outer adult will both be very confused and very happy.
- Add a sprinkle of sea salt: Especially if you’re grilling—it cuts through the sweetness and makes everything pop.
- Swap marshmallow fluff with almond marshmallow cream: If you can find it, the nutty twist is subtle but seriously good.
What to Serve with Fluffernutter Sandwich
This sandwich is loud in the sweetness department, so thinking about contrast helps. Or lean into the theme and treat it like dessert. Either way works.
-
A bowl of creamy broccoli slaw gives you crunch, freshness, and just enough tang to balance peanut butter’s richness. Plus, it’s green, so clearly healthy stuff is happening, right?
-
Apple slices with a squeeze of lemon or a sprinkle of chili powder offer a crisp, tart bite after all that fluff. Keeps things interesting.
-
Pair it with a glass of cold milk—plain old dairy or oat, whatever you’ve got. It’s the daydreamy school cafeteria combo that never gets old.
-
Crunchy vegetable chips or even plain salted ones balance the sweet and savory better than you’d expect. Bonus points if they’re kettle-style; extra crunch always helps.
-
Feeling savory before sweet? Serve it after a light protein like oven-baked lemongrass chicken. It’s a bit unexpected, but very satisfying.

Frequently Asked Questions
Can I make fluffernutter sandwiches ahead of time?
You bet, but they’re definitely best eaten fresh. If you assemble them too early, the fluff can start to soak into the bread and you lose that pillowy bounce. If you’re planning ahead, try storing peanut butter and fluff on separate slices and assembling just before eating. That way they stay fluff-tastic.
What’s the best bread for a fluffernutter sandwich?
Soft, squishy white bread is traditional and honestly ideal—it clings to the peanut butter and fluff like a charm. But if you prefer whole wheat or sourdough, go for it. Just know that denser bread might compete with the fillings a bit, and grilled versions turn out firmer with thicker slices.
Can I grill the sandwich like a grilled cheese?
Oh yes—and I highly recommend it. Spread butter on the outside (like you would grilled cheese), then toast each side in a skillet over medium-low heat. It gets golden and crisp on the outside and turns into melty sweet goo on the inside. Hold onto your napkins… it’s messy in the best way.
Is marshmallow fluff the same as melted marshmallows?
Not quite. Marshmallow fluff is spreadable and whippy, while melted marshmallows tend to seize up or get too chewy once they cool. If you’re substituting, proceed with caution—it won’t ruin the sandwich, but the texture won’t be the same plush, sticky cloud experience.
