Ingredients

  • 1 cup salted butter
  • 3/4 cup creamy peanut butter
  • 1 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 egg
  • 2 cups all-purpose flour
  • 1/2 tsp salt
  • 1/2 tsp baking soda
  • 4 oz marshmallow fluff

Instructions

  • Preheat the oven to 350° F.
  • Line your baking sheet with parchment paper or a silicone baking mat. Set aside.
  • In the bowl of a stand mixer or with an electric hand mixer, cream together the butter, peanut butter, brown sugar and sugar until well combined.
  • Scrape the sides of the bowl and add in the egg. Mix until combined.
  • Add the flour, baking soda and salt, mix until the sticky dough forms.
  • Add the marshmallow fluff in a few separate dollops to the mixer bowl. Mix in short spurts until the marshmallow fluff is marbled through the cookie dough.
  • Scoop out the dough in 1 1/2 tbsp portions (#40 scoop) and arrange on a parchment lined cookie sheet.
  • Bake at 350° F for 11-13 minutes. The cookie will spread some and the edges should start to turn golden brown when they are ready to come out of the oven.
  • Allow the cookies to completely cool on the pan.
  • Store in an airtight container at room temperature for up to 3 days or in the freezer for up to 3 months. Enjoy!
