Ingredients

  • ½ cup (1 stick / 113 g) unsalted butter, softened
  • cup (170 g) creamy peanut butter
  • ½ cup (100 g) granulated sugar
  • ½ cup (100 g) light brown sugar, packed
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1 cup (125 g) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon kosher salt
  • 1 cup (50 g) mini marshmallows
  • ½ cup (91 g) semi-sweet chocolate chips
  • ½ cup (91 g) peanut butter chips

Instructions

  • In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), cream together the butter, peanut butter, granulated sugar, and brown sugar on medium speed until smooth and fluffy.
  • Add the egg and vanilla extract. Mix until fully incorporated.
  • In a separate medium bowl, whisk together flour, baking soda, and salt.
  • Add the dry ingredients to the peanut butter mixture. Mix on low speed just until the flour is fully incorporated; do not overmix.
  • Gently fold in the marshmallows, chocolate chips, and peanut butter chips until evenly distributed.
  • Cover the bowl with plastic wrap and refrigerate for 1 hour, or until the dough is firm.
  • When ready, preheat the oven to 350°F. Line a baking sheet with parchment paper.
  • Using a 2-tablespoon scoop, drop the cookie dough onto the lined baking sheet, leaving about 2 inches between each cookie.
  • Bake for 10 minutes, or until the edges turn a light golden color and the centers look set but still soft. Do not overbake.
  • Remove the cookies from the oven and let them cool on the baking sheet for 1 minute. Then transfer them to a wire rack to cool completely.
