4.5 from 454 reviews

Fluffernutter Cookies combine the classic flavors of peanut butter and marshmallow fluff into soft, chewy cookies. These easy-to-make treats offer a nostalgic taste with a gooey marshmallow center and a tender peanut buttery bite, perfect for quick baking and delightful snacking.

Ingredients

Scale

Cookie Dough

  • 1 cup peanut butter (creamy or chunky)
  • 1 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 1/2 cups all-purpose flour
  • 1/2 cup marshmallow fluff (for folding into dough and topping)

Instructions

  1. Prepare the Dough: In a large mixing bowl, combine the peanut butter and granulated sugar until smooth. Add the egg and vanilla extract, mixing thoroughly. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually incorporate the dry ingredients into the peanut butter mixture until a soft dough forms. Stir in half of the marshmallow fluff gently to create a swirled effect within the dough.
  2. Scoop Dough onto Baking Sheet: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. Using a tablespoon or cookie scoop, drop rounded portions of dough onto the sheet, spaced about 2 inches apart.
  3. Add Marshmallow Topping: Place a small dollop of the remaining marshmallow fluff on top of each cookie dough mound to create a gooey marshmallow center after baking.
  4. Bake the Cookies: Bake in the preheated oven for 10-12 minutes, or until the edges are set but the centers remain soft. Avoid overbaking to keep the cookies chewy.
  5. Cool and Serve: Remove the cookies from the oven and let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. Enjoy with a cold glass of milk or as a sweet snack anytime.

Notes

  • For a gluten-free version, substitute all-purpose flour with a gluten-free flour blend.
  • Use creamy peanut butter for a smoother texture, or chunky if you prefer nutty bites in your cookies.
  • Marshmallow fluff can be gently warmed to make it easier to fold into the dough and to spread on top.
  • Store cookies in an airtight container at room temperature for up to 3 days to maintain freshness.
  • These cookies freeze well; freeze baked cookies in a sealed container for up to 1 month.
