Servings 11 sandwich cookies


  • cup unbleached all-purpose flour
  • ½ teaspoon baking soda
  • teaspoon salt
  • ½ cup cacao powder
  • ¾ cup salted butter, room temperature
  • 1 cup raw sugar
  • 3 tablespoons sour cream
  • 1 teaspoon vanilla extract
  • 2 eggs
  • ½ cup chopped semi sweet cooking chocolate, melted
  • ½ cup marshmallow creme (Fluff)
  • Funfetti


For the cookies

  • In a mixing bowl, whisk together the flour, baking soda, salt, and cacao powder. Set aside.
  • In another mixing bowl, with a hand mixer cream the butter, sugar, sour cream, and vanilla together until they are all combined.
  • Add the eggs, one at a time, mixing well in-between each.
  • Pour half of the dry ingredient mixture into the wet and mix with the hand mixer. Gradually add the rest of the dry ingredients. Mix until well incorporated. Don't over mix.
  • With a medium-size cookie scoop (1 1/2 tablespoon), scoop the dough and make balls. Place them in your air fryer basket. They need to be spaced out so they won't touch. I would strongly suggest using parchment paper as the dough is very sticky. The batter will make approximately 22 cookies, so 11 sandwiches.
  • Cook at 320 degrees F for 8 minutes.
  • Let them cool in the basket for 2 to 3 minutes then transfer to a cooling rack and cool completely.
  • In the meantime, melt the chocolate in the microwave-safe bowl, about 2 minutes, mix every 15 seconds.


  • Once the cookies are completely cooled, dip the top half of the cookies (11) in the melted chocolate. Then add a sprinkle of funfetti on top. Repeat the process. Set aside until they harden. Living in Florida, I put mine in the fridge to accelerate the process.
  • On the remaining cookies, spread some marshmallow fluff on the bottom, approximately 1 to 1 1/2 teaspoon. If you are like my kids and love marshmallow fluff, you can put more but be advised it will overflow. Top the marshmallow with the cookie that was dipped in chocolate and funfetti. Keep refrigerated until ready to serve.


Note: If you want to bake the cookies in the oven, preheat your oven to 350 degrees F. Line a cookie sheet with parchment paper and cook your cookies for 8 to 10 minutes or until the edge are golden.
