Ingredients

  • 1 ½ cup flour
  • ½ teaspoon baking soda
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • ½ cup unsalted butter softened
  • ¼ cup white sugar
  • ¾ cup lightly packed brown sugar
  • ½ cup peanut butter, creamy
  • 2 teaspoon vanilla
  • 1 large egg
  • 1 cup mini marshmallows
  • ¼ cup marshmallow fluff

Instructions

  • In a mixing bowl cream together butter and sugars.
  • Add in egg and vanilla, mix again.
  • Add in peanut butter and mix again to combine until smooth.
  • In another bowl whisk together the flour, baking powder, baking soda, and salt.
  • Add dry ingredients to peanut butter mixture. Stir until just combined.
  • Fold in mini marshmallows until well distributed.
  • Place the marshmallow fluff into the bowl of cookie dough and stir lightly to distribute it. You want it to be like a ripple of marshmallow flowing throughout the dough. Dont over mix it.

  • Place the dough balls on a parchment lined baking sheet and bake at 350 F for 8-10 minutes.
