🍽️ servings 4
⚡ Difficulty easy

intro

A nostalgic no-cook New England classic pairing creamy salted peanut butter and pillowy marshmallow fluff between soft white bread, ideal for casual summer outings.

Ingredients

Soft white sandwich bread 8 slices (320 grams total)
Creamy salted no-stir peanut butter 1 cup (256 grams)
Marshmallow creme (marshmallow fluff) ½ cup (60 grams)

Steps

1

Prep your workspace

Clear a clean, dry countertop or wooden cutting board, and lay out all measured ingredients: 8 slices (320g) of soft white sandwich bread, 1 cup (256g) of creamy no-stir peanut butter, and ½ cup (60g) of marshmallow creme. Let refrigerated marshmallow creme sit at room temperature for 10 minutes for easier spreading, then set out a clean small offset spatula or butter knife for spreading.

Step 1
step1:Prep your workspace
2

Spread peanut butter layer

Set 4 bread slices on the cutting board. Use your spatula to spread 4 tablespoons (64g) of peanut butter evenly across the entire top surface of each slice, spreading all the way to the crust edges. Use gentle, smooth strokes to avoid tearing the soft, delicate bread crumb.

Step 2
step2:Spread peanut butter layer
3

Spread marshmallow creme

Take the remaining 4 bread slices, and wipe your spatula completely clean to avoid cross-contaminating the marshmallow creme. Spread 2 tablespoons (15g) of room-temperature marshmallow creme evenly across the entire top surface of each slice, spreading gently to the crust edges, as the fluffy creme stretches easily when warm.

Step 3
step3:Spread marshmallow creme
4

Assemble sandwich layers

Lift one peanut butter-covered slice and one marshmallow creme-covered slice, and press the two spread sides firmly together, aligning the crust edges perfectly. Apply light, even pressure across the top of the sandwich to help the fillings adhere without squeezing excess filling out the sides. Repeat with the remaining bread slices to form 4 full sandwiches.

Step 4
step4:Assemble sandwich layers
5

Cut sandwiches for serving

Use a sharp serrated knife to cut each sandwich diagonally into two equal triangular halves, using a slow sawing motion to avoid squishing the soft bread and squeezing out filling. For picnic transport, insert one 3-inch frilled toothpick through the center of each half to hold layers in place.

step5:Cut sandwiches for serving
6

Serve or pack for later

Serve the sandwiches immediately for the softest, gooiest texture, paired with cold milk if desired. For transport, place sandwiches in an airtight container with a 4x4 inch sheet of parchment paper between each sandwich to prevent sticking, and store at cool room temperature for up to 4 hours. Do not refrigerate, as cold temperatures will dry out the bread and stiffen the fillings.

Tips

1.Let refrigerated marshmallow creme sit at room temperature for 10 minutes before spreading; cold fluff is overly sticky and will tear soft white bread easily.
2.Use no-stir creamy peanut butter instead of natural oil-separated peanut butter; the separated oil in natural peanut butter will soak into the bread and create soggy spots.
3.Stick to the 2-tablespoon per slice measurement for marshmallow creme; too much fluff will ooze out the sides when cutting or biting into the sandwich, creating a sticky mess.

Fluffernutter Sandwich:Frequently Asked Questions

1.What defines a true classic fluffernutter, rather than a random peanut butter and marshmallow sandwich?
A classic fluffernutter is the nostalgic no-cook New England staple that sticks to three core components: soft white sandwich bread, creamy salted no-stir peanut butter, and pillowy marshmallow fluff. It skips fussy add-ins, prioritizes that perfect salty-sweet balance and soft, squishy texture, and is traditionally served cold with no toasting required for authenticity.
2.Do I have to use no-stir creamy peanut butter, or can I use natural stirred peanut butter?
No-stir creamy salted peanut butter is ideal for authentic texture, as it has a smooth, stable, spreadable consistency that won’t seep into bread or separate as you eat. If you only have natural peanut butter, stir it extremely well and chill it for 10 minutes before spreading to avoid runny, oily messes that make your sandwich soggy.
3.Is there a difference between marshmallow creme and marshmallow fluff for this recipe?
For all practical fluffernutter purposes, they’re interchangeable! Marshmallow Fluff is the iconic New England brand name for the spread, while marshmallow creme is the generic term for the same light, vanilla-forward marshmallow spread. Skip solid block marshmallows, as they won’t spread smoothly or deliver that classic fluffy texture.
4.Should I toast the bread for a classic fluffernutter?
The traditional New England fluffernutter uses untoasted soft white bread for that soft, squishy, nostalgic bite. If you prefer a little crunch, you can lightly toast bread, but let it cool completely before spreading—warm bread will melt the fluff and peanut butter, leading to a runny, oozing mess that loses its signature texture.
5.How do I keep my fluffernutter from getting soggy when packing it for summer outings?
The easiest trick is to spread a thin, even layer of peanut butter on both slices of bread first, creating a moisture barrier between the bread and marshmallow fluff. Pack it in an airtight container with a small ice pack if you’re heading out on a hot day, to keep spreads from getting too runny as temperatures rise.
6.What’s the ideal ratio of peanut butter to marshmallow fluff for the best flavor?
Aim for an even 1:1 ratio by volume, spreading roughly 2 tablespoons of peanut butter and 2 tablespoons of marshmallow fluff per sandwich. The salt from the peanut butter cuts the super-sweet fluff perfectly at that balance—too much fluff tastes cloying, while too much peanut butter overpowers that light, pillowy marshmallow flavor.
7.Can I use crunchy peanut butter instead of creamy for a classic fluffernutter?
Crunchy peanut butter adds a nice nutty textural pop if you prefer a little bite, but it’s not the traditional choice for a classic fluffernutter. If you do opt for crunchy, pick a no-stir variety to avoid oil seepage, and stick to the same 1:1 spread ratio to keep that iconic salty-sweet balance the sandwich is known for.
8.What are some common, regionally popular customizations for a fluffernutter?
The purist version has no add-ins, but common New England customizations include a thin layer of grape jelly, a light sprinkle of flaky sea salt, a few thin slices of banana, or a tiny drizzle of honey. Keep add-ins thin so they don’t overpower the core pairing, and skip wet ingredients that will make bread soggy.
9.How long can I store a pre-made fluffernutter in the fridge?
A pre-assembled fluffernutter will stay fresh for up to 24 hours in the fridge if wrapped tightly in plastic wrap or stored in an airtight container. Don’t store it longer than that, as the bread will start to go stale and the marshmallow fluff may seep into the bread, leading to a mushy, unappetizing texture.
10.Can I make a gluten-free version of a classic fluffernutter?
Absolutely! The core spreads—peanut butter and marshmallow fluff—are almost always naturally gluten-free, so you just need to swap regular soft white sandwich bread for your favorite soft gluten-free white sandwich bread. Pick a soft, squishy variety rather than a crusty artisanal loaf to match the classic texture.
11.How do I stop marshmallow fluff from sticking to my knife when I spread it?
Fluff is famously sticky, but there’s a simple hack! Lightly coat your butter knife or offset spatula with a tiny bit of nonstick spray, or dip it in warm water and wipe off the excess before spreading. This lets the fluff glide smoothly instead of clinging to the utensil and pulling into sticky, uneven clumps.
12.Are fluffernutters safe for young toddlers to eat?
Fluffernutters are a beloved kid-friendly snack, but for toddlers under 4, spread the peanut butter in a very thin, even layer (no thick globs) to reduce choking risk, and cut the sandwich into thin strips or small bite-sized pieces. Skip add-ins like whole nuts or thick banana chunks for little ones to keep bites soft and easy to chew.
13.Can I make a vegan version of a classic fluffernutter?
You absolutely can! Most mainstream marshmallow fluff brands are vegan these days, as they no longer use gelatin in their recipes, but double-check the label to confirm. Pair it with a vegan no-stir creamy salted peanut butter and soft vegan white sandwich bread for a dead ringer for the classic New England sandwich.
14.Is it true that the fluffernutter has been proposed as an official state sandwich?
That’s a real bit of New England food trivia! Multiple bills have been introduced in the Massachusetts state legislature since the early 2000s to name the fluffernutter the official state sandwich, honoring its deep local roots—Marshmallow Fluff was first invented in Somerville, MA, way back in 1917.
15.What’s the best bread substitute if I can’t find soft white sandwich bread?
If plain soft white sandwich bread is hard to track down, reach for soft pullman loaf, unseeded soft hamburger buns split flat, or even soft Hawaiian sweet bread as a close second. Avoid crusty sourdough, dense whole grain bread, or seeded rye, as their strong flavors and firm texture clash with the creamy, sweet spreads.
16.Why does my fluffernutter always ooze filling out the sides when I take a bite?
Oozing usually stems from two common mistakes: spreading the layers too thick, or using warm, runny peanut butter or softened, melted fluff. Stick to 2 tablespoons of each spread per sandwich, use chilled no-stir peanut butter, and don’t press down too hard on the top bread slice to keep fillings neatly contained.

OMG, I haven’t had a fluffernutter since I was a kid in elementary school! This recipe is exactly how I remembered it – perfectly sweet, so messy in the best way. My 7 year old begged for a second one after school today. Total game changer for quick after-school snacks!

yesterday

Same! I forgot how simple and tasty these are, I used to trade my carrot sticks for my best friend’s fluffernutter at lunch all the time

So glad this brought back happy childhood memories! Pro tip: toast the bread *very* lightly if you want a little extra crunch without the marshmallow fluff melting too much

Wait, I always thought fluffernutters had peanut butter AND jelly? Tried it the classic way for our neighborhood potluck last weekend and folks went crazy for it. Who knew skipping the jelly was the move? SO good.

So happy it was a potluck hit! The classic is really just equal parts creamy peanut butter and marshmallow fluff, no jelly required – though we won’t judge if you add a little bacon for a salty twist!

Swapped the regular peanut butter for my go-to organic crunchy peanut butter and used vegan marshmallow fluff, and this still slapped! Perfect quick work from home lunch when I don’t feel like cooking. 10/10

Wait try spreading a tiny bit of Nutella on one slice too, trust me it’s insane. I make these for late night study sessions with my roommates all the time

Love that this works for busy study schedules! Just a heads up, if you’re packing these to go to the library, stick the sandwich in a hard sided container so the fluff doesn’t squish out all over your notebooks!

Took these on a day hike last weekend and they held up way better than I thought they would! No sogginess, the energy boost from the peanut butter was perfect for that last steep mile. Only complaint is I wish I packed two.

What a perfect hiking snack! We love wrapping ours in wax paper to keep them from getting squished in a backpack, so glad they worked out for your trek!

Grew up on these, can confirm the ratio is key – equal parts peanut butter and fluff, no skimping on either! Used extra crunchy peanut butter like my grandma always did and it was perfect. 10/10 no notes.

These are so tasty! Quick question – can you prep these ahead for the week for school lunches? I’m always looking for no-reheat lunch options that don’t get gross by Wednesday.

I prepped these for my kids last week and they were totally fine for 3 days in the fridge! Just don’t use super soft bread, it gets a little mushy. Sourdough works great

I ordered a fluffernutter at a diner last month and they charged me $8 for it??? Making it at home is so much cheaper and tastes better, honestly. I used that super thick marshmallow fluff from the jar in the baking aisle, exactly like the old days.

Right?! Restaurant upcharges are insane for the simplest stuff. I calculated these cost like 75 cents each to make at home, can’t beat that

Homemade is always better (and easier on the wallet)! If you want that diner-style vibe, serve it with a side of potato chips and a dill pickle, it’s the classic combo

My super picky 5 year old who turns down every sandwich I make ate the entire thing in 2 minutes. I almost cried. This is going into our permanent weekly lunch rotation, thank you so much for the easy win!

Used my favorite gluten-free white bread for this and it worked perfectly! I was worried the texture would be off but it was just like the fluffernutters I ate as a kid before my celiac diagnosis. So happy!

yesterday

That makes us so happy to hear! We love that this recipe is super easy to adapt for different dietary needs, so everyone can enjoy the classic fluffernutter

just now

Added a sprinkle of flaky sea salt on top of the peanut butter before adding the fluff and oh my GOD, that sweet-salty combo is out of this world. Don’t knock it till you try it.
