There is something instantly nostalgic about a cookie that tastes like peanut butter, marshmallow, and pure comfort all in one bite. These Soft and Chewy Fluffernutter Cookies bake up with golden edges, tender centers, and little pockets of gooey marshmallow that make every cookie feel extra special.

I love making these when I want a dessert that feels playful but still completely homemade. The peanut butter brings richness, the marshmallow creme keeps the texture soft, and the peanut butter chips tucked throughout make them even more irresistible. They are the kind of cookies that disappear fast from the cooling rack.

What Makes Fluffernutter Cookies So Soft and Chewy?

The softness comes from a combination of butter, brown sugar, peanut butter, and marshmallow creme. Brown sugar helps hold moisture in the dough, while the marshmallow adds light, sticky pockets throughout the cookies. A slightly underbaked center also helps create that soft and chewy finish once the cookies cool.

If you want the best texture, avoid overmixing the dough and do not bake them too long. The cookies should look just set at the edges while the centers still appear a little soft.

Ingredients for the Soft and Chewy Fluffernutter Cookies

Each ingredient plays an important part in creating cookies that are rich, tender, and full of that classic fluffernutter flavor.

Unsalted butter gives the cookies richness and helps create those lightly crisp edges.

Creamy peanut butter is the heart of the recipe, adding bold nutty flavor and a soft, satisfying texture.

Brown sugar brings moisture and chewiness while adding a subtle caramel note.

Granulated sugar helps balance the texture and gives the cookies a delicate sweetness.

Egg binds everything together and helps the cookies bake up tender.

Vanilla extract adds warmth and rounds out the peanut butter flavor.

Marshmallow creme creates those gooey pockets that make these cookies feel extra special.

All-purpose flour gives the dough structure so the cookies hold their shape.

Baking soda helps the cookies rise just enough and keeps them from becoming too dense.

Salt sharpens all the sweet and nutty flavors.

Peanut butter chips add even more peanut butter goodness and a soft, melty bite.

How To Make the Soft and Chewy Fluffernutter Cookies

This cookie dough comes together easily, and the magic happens when the marshmallow and peanut butter bake into soft, golden cookies.

Step 1: Cream the Butter, Peanut Butter, and Sugars

In a large mixing bowl, beat the softened butter, creamy peanut butter, brown sugar, and granulated sugar until the mixture looks light and fluffy. This step helps create a smooth dough and gives the cookies their tender texture.

Step 2: Add the Egg and Vanilla

Mix in the egg and vanilla extract until fully combined. Scrape down the sides of the bowl so everything blends evenly.

Step 3: Fold in the Marshmallow Creme

Add the marshmallow creme and mix gently until it is swirled through the dough. It does not need to be perfectly smooth. A few streaks are fine and help create gooey bites in the finished cookies.

Step 4: Add the Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, and salt. Slowly add the dry mixture to the wet ingredients and mix just until no dry patches remain.

Step 5: Stir in the Peanut Butter Chips

Fold in the peanut butter chips so they are evenly distributed throughout the dough. This gives every cookie extra flavor and little creamy pockets once baked.

Step 6: Scoop and Bake

Scoop the dough onto a parchment-lined baking sheet, leaving space between each cookie. Bake until the edges are lightly golden and the centers still look soft. Let them rest on the pan for a few minutes before moving to a wire rack.

Step 7: Cool and Enjoy

Once cooled slightly, the cookies will settle into that soft and chewy texture. Enjoy them warm for the gooiest marshmallow center, or cool completely for a perfect lunchbox or dessert tray cookie.

This recipe makes about 24 cookies, depending on the size of your scoop, and comfortably serves 8 to 12 people.

Serve these cookies slightly warm if you want the marshmallow to feel extra soft and melty. They are wonderful with a cold glass of milk, hot coffee, or tucked into a dessert platter with other homemade favorites.

To store, keep the cookies in an airtight container at room temperature for up to 4 days. You can also refrigerate them for a slightly firmer texture or freeze them for longer storage. If freezing, place parchment between layers so they do not stick together.
