These Fluffernutter Stuffed Peanut Butter Cookies are the ultimate mashup of soft peanut butter cookies and nostalgic fluffernutter sandwiches. Each cookie hides a gooey marshmallow inside, surrounded by a rich, tender peanut butter dough dotted with peanut butter chips. It’s a warm, chewy dessert with a molten heart that’ll have everyone reaching for seconds.
The Inspiration Behind Fluffernutter Stuffed Peanut Butter Cookies
The fluffernutter sandwich—a New England childhood staple made from peanut butter and marshmallow creme—gets a cookie makeover in this fun, indulgent dessert. The contrast between the salty peanut butter and the gooey sweetness of melted marshmallow is what makes this combination such a hit.
By tucking a whole marshmallow into the center of each cookie and baking until just golden, you get that irresistible creamy center that oozes when warm and softens into chewy bliss as it cools.

Notes
1
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2
In a medium bowl, whisk together the flour, baking soda, and salt.
3
In a large bowl, cream together the softened butter, peanut butter, granulated sugar, and brown sugar until light and fluffy.
4
Beat in the egg and vanilla extract until well combined.
5
Gradually add the dry ingredients to the wet, mixing until a soft dough forms.
6
Scoop out a tablespoon of dough and flatten it into a disc. Place a spoonful of half marshmallow fluff and half creamy peanut butter in the center and fold the dough around the fluff, rolling it into a ball.
7
Place the dough balls onto the prepared baking sheet, spacing them about 2 inches apart. Lightly press down on each ball to flatten slightly.
8
Bake in the preheated oven for 8-10 minutes or until the edges are golden. The centers might appear slightly underbaked.
9
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
