Ingredients You’ll Need
The beauty of this Fluffernutter Cookies Recipe lies in its simplicity and quality ingredients. Each one plays a starring role in creating the perfect texture, flavor, and that gorgeous golden color that invites you to take a bite immediately.
- Unsalted butter (1/2 cup, room temperature): Adds richness and helps create a tender, buttery base for the cookies.
- Creamy peanut butter (1/2 cup): Provides that signature nutty flavor and adds moisture to keep the cookies soft.
- Light brown sugar (1/2 cup, packed): Contributes a subtle caramel note and chewy texture.
- Granulated sugar (1/4 cup): Balances sweetness and assists with slight crisping on the edges.
- Large egg (1): Binds everything together while adding structure and a touch of fluffiness.
- Vanilla extract (1 tsp): Enhances all the other flavors with a warm, aromatic touch.
- All-purpose flour (1 1/4 cups): Forms the body of the cookie, giving it stability and chew.
- Baking soda (1/2 tsp): Leavens the dough just enough for softness without too much rise.
- Salt (1/4 tsp): Elevates the sweetness and highlights the peanut butter’s depth.
- Marshmallow fluff (1/2 cup, plus extra for swirling): The key star that adds gooey pockets of sweetness and delightful texture swirls throughout.
How to Make Fluffernutter Cookies Recipe
Step 1: Prep Your Oven and Baking Sheet
Start by preheating your oven to 350°F (175°C). You’ll want to line your baking sheets with parchment paper or use silicone mats to prevent sticking and to help with even baking. This small step ensures your cookies come out perfectly every time.
Step 2: Cream the Butters and Sugars
Add your softened butter, creamy peanut butter, light brown sugar, and granulated sugar into a large mixing bowl. Beat them together for 2 to 3 minutes until the mixture is light, fluffy, and utterly inviting. This step is crucial as it aerates the dough, contributing to that soft, melt-in-your-mouth texture.
Step 3: Incorporate the Egg and Vanilla
Next, crack in one large egg and pour in the vanilla extract. Mix well but don’t overdo it here — just enough to combine everything smoothly. The egg adds moisture and structure, while the vanilla ties the flavors together with subtle warmth.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together your all-purpose flour, baking soda, and salt. This ensures the leavening is evenly distributed and the salt doesn’t clump. Gradually fold this dry mix into your wet ingredients, being careful to mix only until just combined to keep the cookies tender.
Step 5: Fold in Marshmallow Fluff
Here’s where the magic happens: spoon half a cup of marshmallow fluff into the dough. Gently fold it using a spatula to create lovely swirls of gooey sweetness visible throughout the cookie dough. Resist the urge to overmix because you want those pockets of fluff to stay intact and gooey.
Step 6: Scoop the Dough
Use a cookie scoop or tablespoon to drop rounded spoonfuls of dough onto your prepared baking sheets, spacing them about two inches apart. This gives the cookies room to spread without baking into each other.
Step 7: Bake to Perfection
Bake for about 9 to 11 minutes until the edges turn golden and the centers still look slightly underbaked. This is key for keeping the cookies soft and chewy rather than dry and hard. The slightly underbaked center will firm up as the cookies cool.
Step 8: Cool and Enjoy
Allow your cookies to cool on the baking sheet for five minutes before transferring them to a wire rack. This prevents breakage and helps them set to that perfect chewy texture. At this point, the aromas wafting through your kitchen should have you reaching for a glass of milk!
How to Serve Fluffernutter Cookies Recipe
Garnishes
For an extra-special touch, consider drizzling a little extra marshmallow fluff on top of warm cookies. Sprinkle some crushed peanuts or a tiny pinch of sea salt to balance the sweetness and add a bit of crunch. These simple garnishes can take your Fluffernutter Cookies Recipe from awesome to show-stopping.
Side Dishes
These cookies pair wonderfully with a cold glass of milk or a hot cup of coffee. If you’re serving these at a gathering, consider offering creamy vanilla ice cream or rich hot chocolate alongside for a decadent dessert spread that everyone will rave about.
Creative Ways to Present
Try stacking the cookies with a dollop of marshmallow fluff between two of them to recreate the nostalgic fluffernutter sandwich experience with a cookie twist. Alternatively, arrange them on a colorful platter surrounded by peanut butter cups for a delightful peanut butter-themed dessert board.
Make Ahead and Storage
Storing Leftovers
Once cooled completely, store your Fluffernutter Cookies Recipe in an airtight container at room temperature. They will stay fresh and chewy for up to five days, making them a great make-ahead treat for busy weeks or casual get-togethers.
Freezing
You can freeze the baked cookies by layering them between parchment paper sheets inside a freezer-safe container or bag. They freeze beautifully for up to three months. When you’re ready to enjoy, just thaw at room temperature to bring back that soft, chewy goodness.
Reheating
If you want to revive the gooey, melty charm of these cookies, pop them in the microwave for about 10 to 15 seconds or warm them briefly in a low oven. This little reheating tip breathes new life into leftovers and makes all the difference when enjoying your Fluffernutter Cookies Recipe later.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add a delightful texture and a bit of extra nuttiness to your cookies. Just be aware it might change the chew slightly but in a very tasty way.
Is marshmallow fluff necessary or can I substitute it?
Marshmallow fluff is the secret to the signature gooey swirls in this recipe and is highly recommended. If you can’t find it, try using mini marshmallows chopped finely, but the texture won’t be quite the same.
What if I don’t have brown sugar?
You can substitute with white sugar plus a tablespoon of molasses per 1/2 cup to replicate the flavor of brown sugar, but the original brown sugar will give you the best caramel notes and moisture.
Can I make these cookies gluten-free?
Yes! Swap the all-purpose flour with a good-quality gluten-free flour blend in equal amounts. Just make sure your blend contains xanthan gum or a similar binder to keep the cookie texture intact.
How thick should I scoop the dough for these cookies?
Use roughly a tablespoon or cookie scoop size that results in 2-inch diameter dough balls. This size bakes up perfectly with soft centers and crispy edges, giving you the ultimate Fluffernutter Cookies experience.
