Equipment

  • Mixing bowls
  • Electric mixers or stand mixer
  • Rubber spatula
  • Baking sheet
  • Parchment paper
  • Cooling rack for cooling
  • Spoon for portioning dough

Ingredients

  • 115 gr butter at room temperature
  • 190 gr creamy peanut butter Skippy type or similar
  • 100 gr cane sugar light
  • 100 gr granulated sugar
  • 1 nr egg large
  • 1 teaspoon vanilla extract
  • 187 gr 00 flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 12 nr marshmallows large
  • 80 gr peanut butter chips or chocolate chips
  • Sea salt flakes optional

Instructions

  • In a large bowl, beat the butter and peanut butter with electric mixers until smooth.
  • Add both sugars and mix on low speed for about 3 minutes, until well combined.
  • Incorporate the egg and vanilla extract, continuing to mix on low speed for another minute.
  • In a separate bowl, mix the flour, baking soda, and salt.
  • Add the dry ingredients to the butter and egg mixture, mixing on low speed until just incorporated. Finish mixing with a rubber spatula.
  • Let the dough rest in the fridge for at least 30 minutes.
  • To fill the cookies, take about 3 tablespoons of dough and flatten it on your palm to form a disc about 8 cm in diameter and 0.5 cm thick.
  • Place a marshmallow in the center of the disc and wrap the dough around, sealing well. If cracks appear, press them with your fingers to close.
  • Repeat the process for all 12 cookies, then press some peanut butter chips on the surface of each dough ball.
  • Chill the cookies in the refrigerator while preheating the oven to 180°C.
  • Arrange the dough balls on baking sheets lined with parchment paper, spaced about 5 cm apart, with the sealed side down.
  • Bake for 10-11 minutes, turning the sheets halfway through. The cookies will crack slightly on the surface revealing the marshmallow.
  • Remove from oven and, if desired, sprinkle with some sea salt flakes.
  • Let the cookies cool on the sheet until they are firm enough to transfer to a wire rack.

Notes

Tips and Variations

  • If you prefer, you can replace the peanut butter chips with dark or milk chocolate chips.
  • It is important to let the cookies cool completely on the sheet before moving them, as they are quite fragile when still warm.
  • Some marshmallows may ooze out during baking. Don't worry, the cookies will still be delicious!
  • If you want to prepare the dough in advance, you can freeze the pre-filled dough balls with marshmallow for up to one month. Thaw in the refrigerator overnight before baking.
  • You cannot use marshmallow cream (Marshmallow Fluff) instead of whole marshmallows, as it lacks the structure needed to create the desired chewy center.
