Nothing says nostalgic comfort like peanut butter and marshmallow, and these Soft and Chewy Fluffernutter Cookies take that classic combo to cookie heaven. With golden edges, pillowy centers, and the occasional burst of gooey marshmallow, these cookies are sweet, salty, and incredibly satisfying. They’re a delightful mashup of a childhood sandwich and a bakery-style cookie, offering the best of both worlds in every bite.

Perfect for potlucks, lunchbox treats, or late-night cravings, these cookies are as easy to make as they are to love. You’ll love how the peanut butter chips add creamy richness while the melted mini marshmallows bring that irresistible fluff. Soft yet chewy, sweet yet slightly salty—they’re dangerously addictive.

What Kind of Peanut Butter Should I Use?

Creamy peanut butter is the best choice for this recipe. It provides smoothness and consistent flavor throughout the dough. Avoid natural peanut butters that separate, as they can cause inconsistent texture. You want a peanut butter that blends smoothly and holds the dough together well.

Ingredients for the Soft and Chewy Fluffernutter Cookies

Creamy Peanut Butter: The heart of the flavor. Creamy texture ensures the cookies stay soft and rich.
Brown Sugar: Adds a depth of flavor and keeps the cookies tender and moist.
Granulated Sugar: Balances the sweetness and helps with structure.
Unsalted Butter: For that melt-in-your-mouth softness and buttery flavor.
Eggs: Binds everything together while adding moisture.
Vanilla Extract: Enhances all the sweet flavors.
All-Purpose Flour: Provides the base structure of the cookie.
Baking Soda & Baking Powder: The dynamic duo that lifts the cookies to the perfect chewy height.
Salt: Brings out the sweetness and balances the peanut butter.
Mini Marshmallows: For the classic fluffernutter gooeyness in every bite.
Peanut Butter Chips: Add creaminess and extra peanut butter punch.

How To Make the Soft and Chewy Fluffernutter Cookies

Step 1: Cream the Butter and Sugars

In a large mixing bowl, beat together the softened unsalted butter, brown sugar, and granulated sugar until light and fluffy. This step helps create a smooth base for your cookies.

Step 2: Add Wet Ingredients

Beat in the creamy peanut butter, eggs, and vanilla extract. Mix until everything is well combined and creamy.

Step 3: Combine Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. Gradually add the dry mixture into the wet mixture, stirring just until combined.

Step 4: Fold in Marshmallows and Chips

Gently fold in the mini marshmallows and peanut butter chips. Be careful not to overmix, so the marshmallows stay intact.

Step 5: Scoop and Chill

Scoop cookie dough balls onto a parchment-lined baking sheet. Chill for 30 minutes to prevent too much spreading.

Step 6: Bake to Perfection

Bake at 350°F (175°C) for 10-12 minutes or until the edges are golden and centers look just set. Cool slightly on the pan before transferring to a wire rack.

How to Store and Serve These Cookies

These cookies are best served slightly warm when the marshmallows are still gooey. If you’re making them ahead, store in an airtight container at room temperature for up to 4 days. For longer storage, freeze baked cookies for up to 3 months. Warm them in the microwave for that fresh-baked softness.
