Equipment

  • Stand mixer with paddle attachment, or handheld mixer
  • Cookie sheet
  • Parchment paper
  • 2 inch cookie scoop

Materials

  • ½ cup unsalted butter, room temperature 113 g
  • ½ cup brown sugar, lightly packed 100 g
  • ¼ cup white sugar 50 g
  • 1 large egg
  • 1 teaspoon vanilla bean paste or extract
  • ¼ teaspoon baking powder
  • ½ teaspoon baking soda
  • 1 cup all-purpose flour 120 g
  • ¼ cup cocoa powder 26 g
  • teaspoon salt
  • 3 oz peanut butter chips or white chocolate chips
  • ¾ cup mini marshmallows
  • Flaky finishing salt

Instructions

  • Start by placing your peanut butter or white chocolate chips in the freezer.
  • In a bowl, sift together the flour, baking powder, baking soda, cocoa powder, and salt and set aside.
  • In the bowl of a stand mixer fitted with the paddle attachment (or with a handheld mixer) cream together the butter and sugars until light and fluffy, about 3 - 4 minutes on medium speed. Add the egg and vanilla and mix until combined, then scrape down the sides.
  • On low speed, add in the dry ingredients until just combined and scrape down the sides, if needed.
  • Add 2 oz of the cold peanut butter chips to the batter and mix on low until just combined, then place the whole bowl in the fridge for 30 minutes.
  • Preheat the oven to 350 degrees F, and line two cookie sheets with parchment paper.
  • Remove the dough from the fridge. Using a 2 inch cookie scoop, roll the dough into balls and add to your prepared sheet pan. Only cook 6 cookies per pan, as they are rather large. To the top and sides of your dough balls, gently push in about 4-5 mini marshmallows and 4-5 peanut butter or white chocolate chips.
  • Bake for 10-12 minutes and sprinkle with flaky sea salt when done. Allow to cool for 1-2 minutes on the pan, then remove to a wire rack to cool completely.
