Ingredients

Scale
  • 1/2 cup unsalted butter, softened
  • 1 cup creamy peanut butter
  • 3/4 cup brown sugar, packed
  • 1/4 cup granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1 1/4 cups all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup semi-sweet chocolate chips or chopped chocolate bars
  • 1 cup mini marshmallows
  • 3/4 cup graham cracker pieces (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
  2. In a large mixing bowl, beat together butter, peanut butter, brown sugar, and granulated sugar until light and fluffy (2–3 minutes).
  3. Add egg and vanilla extract; mix until just combined.
  4. In a separate bowl, whisk together flour, baking soda, and salt. Gradually add to the wet mixture, mixing on low until just combined.
  5. Fold in chocolate chips, mini marshmallows, and graham cracker pieces. If dough is sticky, chill for 10 minutes.
  6. Scoop dough (about 2 tablespoons per cookie) onto prepared baking sheet, spacing 2 inches apart. Press extra marshmallows and chocolate chips on top if desired.
  7. Bake for 10–12 minutes, until edges are set and tops are crackled. Marshmallows should be golden and puffy.
  8. Cool cookies on baking sheet for 5 minutes, then transfer to a wire rack to finish cooling.

Notes

Chilling the dough helps prevent spreading and keeps cookies thick and chewy. For extra gooey marshmallows, add some halfway through baking or right after cookies come out of the oven. Graham crackers are optional for crunch. Store cookies in an airtight container for up to 4 days, or freeze for up to 2 months.
