Fluffernutter Cookies are soft and chewy peanut butter cookies filled with gooey marshmallow fluff, combining rich nutty flavor with sweet marshmallow cream for a delightful treat perfect for any occasion.

Ingredients

Scale

Cookie Dough

  • ½ cup (129 g) creamy peanut butter
  • ½ cup (1 stick / 113 g) unsalted butter, room temperature
  • 1 cup (200 g) light brown sugar, packed
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1½ cups (187.5 g) all-purpose flour
  • 1 teaspoon cornstarch
  • ½ teaspoon kosher salt

Filling

  • 1 cup marshmallow fluff (or marshmallow creme)

Instructions

  1. Preheat Oven: Preheat the oven to 350°F (175°C) and line two large baking sheets with parchment paper to prevent sticking and ensure even baking.
  2. Mix Peanut Butter, Butter, and Brown Sugar: In a large bowl, combine the creamy peanut butter, softened unsalted butter, and packed light brown sugar. Use a hand mixer to blend the ingredients until smooth and creamy, about 2-3 minutes.
  3. Add Egg and Vanilla: Scrape down the sides of the bowl to incorporate all ingredients, then add the large egg and vanilla extract. Mix until fully combined, about 30 seconds.
  4. Add Dry Ingredients: Add the all-purpose flour, cornstarch, and kosher salt into the bowl. With the mixer on low speed, mix just until the flour mixture is incorporated, about 30 seconds to 1 minute to avoid overmixing.
  5. Scoop and Flatten Dough: Use a 2-tablespoon cookie scoop to portion the dough onto the prepared baking sheets. Then, flatten each dough ball into a disk roughly 3 inches across using your hand.
  6. Add Marshmallow Fluff Filling: Using two spoons to avoid sticky hands, place about 1 tablespoon of marshmallow fluff in the center of each dough disk. Alternatively, pipe the fluff using a piping bag onto the dough discs.
  7. Enclose Filling: Carefully bring the dough around the marshmallow fluff, completely covering it and forming a ball again. Place these filled dough balls back onto the baking sheets, seam side down.
  8. Bake the Cookies: Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are golden brown. Monitor carefully to prevent the marshmallow from burning.
  9. Cool Before Serving: Allow the cookies to rest and cool on the baking sheets for 10-15 minutes to set the filling before serving.

Notes

  • Ensure the butter and egg are at room temperature for better mixing results.
  • Do not overmix the dough after adding dry ingredients to keep cookies tender.
  • Use parchment paper for easy cleanup and to prevent cookies from sticking to the baking sheet.
  • Keep an eye on cookies while baking to avoid burning the marshmallow filling.
  • Marshmallow fluff can be piped for a neater filling application if desired.
