These Fluffernutter Cookies are soft and chewy peanut butter cookies packed with gooey mini marshmallows, combining the nostalgic flavors of a classic fluffernutter sandwich in every delicious bite!

Ingredients

  • All-purpose flour
  • Baking soda
  • Salt
  • Unsalted butter, softened
  • Creamy peanut butter
  • Granulated sugar
  • Brown sugar
  • Large egg
  • Vanilla extract
  • Mini marshmallows (frozen)

Instructions

  • Preheat oven to 350°F and line baking sheets with parchment paper or silicone mats.
  • In a bowl, whisk together flour, baking soda, and salt.
  • In a separate large bowl, cream together butter, peanut butter, granulated sugar, and brown sugar until fluffy.
  • Add egg and vanilla extract; mix until combined.
  • Gradually add dry ingredients to wet ingredients, mixing until just combined.
  • Gently fold frozen mini marshmallows into the dough.
  • Scoop dough into balls and place on prepared baking sheets.
  • Bake for 8–10 minutes or until the edges are set and tops look slightly underdone.
  • Cool on baking sheets for several minutes before transferring to wire racks.

Notes

  • Freeze marshmallows for at least 1–2 hours before baking to prevent excessive melting.
  • Keep extra dough in the fridge between baking batches.
  • Cookies may appear soft when first removed from the oven but will firm up as they cool.
  • Use a silicone mat for easier cookie removal if marshmallows leak out.
