Ingredients You’ll Need

This Fluffernutter Cookies Recipe uses simple, pantry-friendly ingredients that come together beautifully to create a cookie that’s soft, chewy, and packed with flavor. Each item plays a crucial role, whether it’s enhancing the texture or bringing the signature peanut butter goodness that defines this treat.

• Butter (1/2 cup, room temperature): Adds richness and helps create a tender, melt-in-your-mouth cookie texture.
• Creamy peanut butter (1/2 cup): Brings that iconic peanut flavor and moisture that keeps the cookie perfectly soft.
• Granulated sugar (1/2 cup): Provides sweetness and contributes to the cookie’s slight crispness on the outside.
• Light brown sugar (1/2 cup): Adds a subtle caramel note and helps retain moisture for chewiness.
• Large egg (1): Binds everything together while helping with the cookie’s structure.
• Vanilla extract (1 1/2 teaspoons): Enhances all the flavors, giving the cookie a warm, inviting aroma.
• All-purpose flour (1 cup): The sturdy base that supports the cookie’s shape and texture.
• Baking powder (1/2 teaspoon): Provides gentle lift for a soft, light crumb.
• Baking soda (1/2 teaspoon): Helps with browning and contributes to the perfect rise.
• Cornstarch (1 teaspoon): Keeps the cookies extra tender by softening the flour’s protein.
• Kosher salt (1/2 teaspoon): Balances the sweetness and enhances all other ingredients.
• Marshmallow fluff (3/4 cup): The star ingredient that melts into a chewy, gooey center.
• Peanut butter chips (3/4 cup): Sprinkle these on top for added bursts of peanut flavor and a fun texture contrast.

How to Make Fluffernutter Cookies Recipe

Step 1: Prepare Your Oven and Baking Sheets

Start by preheating your oven to 350°F and lining two large baking sheets with parchment paper. This step ensures your cookies bake evenly without sticking, making cleanup a breeze.

Step 2: Cream Butter, Peanut Butter, and Sugars

In a large bowl, combine the peanut butter, butter, granulated sugar, and brown sugar. Use a hand mixer to beat them together until the mixture becomes smooth, creamy, and well blended – usually about 2 to 3 minutes. This creates the ideal base for a soft yet sturdy cookie.

Step 3: Add Egg and Vanilla

Next, mix in the egg and vanilla extract until just combined. These enrich the dough and add moisture needed for a tender cookie crumb.

Step 4: Incorporate Dry Ingredients

Combine the flour, baking powder, baking soda, cornstarch, and kosher salt in a separate bowl, then gradually mix them into the wet ingredients. This careful combination ensures the right structure and rise for your cookies.

Step 5: Scoop and Flatten the Dough

Use a 2-tablespoon cookie scoop to drop dough onto the prepared baking sheets. Once on the sheet, flatten each mound into a roughly 3-inch wide disk – this shape is important for properly encasing the marshmallow fluff later on.

Step 6: Add the Marshmallow Fluff

Scoop out 1 tablespoon of marshmallow fluff and place it right in the center of each flattened dough disk. The fluff will create that irresistibly gooey center that sets this recipe apart.

Step 7: Enclose the Marshmallow Fluff

Carefully bring the edges of the cookie dough up around the marshmallow, sealing it completely inside and forming a ball. This step is key to keeping the marshmallow goo soft and melty inside without leaking out during baking.

Step 8: Arrange on the Baking Sheet

Place each sealed dough ball back onto the lined baking sheet with the sealed side down, preparing them for their final transformation in the oven.

Step 9: Add Peanut Butter Chips

Press a few peanut butter chips into the top of each dough ball. These add a little extra texture and peanut flavor punch to every bite.

Step 10: Bake to Perfection

Bake your cookies for 9 to 10 minutes, or until you see the edges turning a lovely golden brown. This timing ensures a soft, chewy center with slightly crisp edges.

Step 11: Cool Completely

Remove the baking sheets from the oven and transfer the cookies to a wire rack to cool fully. Cooling allows the cookies to set without losing that signature gooey marshmallow core.

How to Serve Fluffernutter Cookies Recipe

Garnishes

For an eye-catching presentation, dust the cooled cookies lightly with powdered sugar or choreograph a drizzle of melted chocolate over the tops. A few extra peanut butter chips scattered around the serving platter add a rustic, charming touch.

Side Dishes

Creative Ways to Present

If you’re hosting a party or gifting these cookies, stack them neatly in a glass jar layered with wax paper or wrap them individually in colorful parchment tied with twine. You can even sandwich them together with a little extra marshmallow fluff for a playful twist on a classic cookie.

Make Ahead and Storage

Storing Leftovers

Keep leftover cookies fresh by storing them in an airtight container at room temperature for up to 3 days. This preserves their soft texture and that signature marshmallow goo without drying out.

Freezing

You can freeze these cookies for longer storage by placing them in a freezer-safe container or zip-top bag. Freeze for up to 3 months, then thaw at room temperature when ready to enjoy.

Reheating

To restore the cookies’ freshly-baked warmth and gooey softness, microwave individual cookies for about 10 to 15 seconds. Be careful not to overheat, or the marshmallow filling might become too soft.

FAQs

Can I use chunky peanut butter instead of creamy?

Chunky peanut butter can be used, but it will add extra texture to your cookies. If you love little peanut chunks, go for it, but creamy peanut butter delivers a smoother dough and more even bake.

Is it necessary to seal the marshmallow fluff inside the dough?

Yes, sealing the fluff inside is what keeps it from leaking during baking and helps create that incredible molten center that defines this Fluffernutter Cookies Recipe.

Can I substitute marshmallow fluff with regular marshmallows?

Regular marshmallows won’t work quite the same since they don’t spread as smoothly and may melt differently. Marshmallow fluff is best for that consistent gooey texture.

How do I make the cookies less sweet?

You can reduce the sugars slightly, but keep in mind the marshmallow fluff and peanut butter chips add sweetness too. Balancing the mix is key for optimal flavor and texture.

Will these cookies hold up well for mailing or gifting?

Absolutely! Pack them carefully with padding to prevent squishing, and they’ll arrive fresh and delicious. Just remember to let recipients know about the marshmallow center so they enjoy them at their best.
