Ingredients

Scale
  • 1 cup salted butter, softened

  • ¾ cup light brown sugar, packed

  • ½ cup granulated sugar

  • 2 large eggs

  • 1 tsp vanilla extract

  • 2 ½ cups all-purpose flour

  • 2 tsp cornstarch

  • 1 tsp baking soda

  • 1 tsp salt

  • 2 cups mini marshmallows, divided

  • 2 cups graham crackers, broken into small pieces (about 910 crackers), divided

  • ½ cup milk chocolate chips

  • ½ cup semisweet chocolate chips

  • 2 Hershey’s bars, broken into pieces

Instructions

  • Preheat your oven to 375°F (190°C). Line 2 baking sheets with parchment paper.

  • In a large bowl, beat the butter, brown sugar, and granulated sugar for 2–3 minutes until creamy.

  • Add the eggs and vanilla, mixing until smooth.

  • Add the flour, cornstarch, baking soda, and salt. Mix until just combined — don’t overmix.

  • Stir in

    • 1 ½ cups graham cracker pieces

    • 1 ½ cups marshmallows

    • both chocolate chip types

  • Scoop 2–3 tablespoon–sized dough balls onto your baking sheets, leaving space for spreading.

  • Bake for 10 minutes, then remove from the oven.

  • Press a few extra marshmallows, graham cracker pieces, and Hershey bar chunks into each cookie.

  • Return to the oven for 1–2 more minutes, or until golden.

    • Optional: Switch to broil for 10–20 seconds to toast the marshmallows — watch closely so they don’t burn!

  • Cool on the pan for 2 minutes, then transfer to a rack.

  • Store in an airtight container for 4–5 days.

Notes

  • Don’t overbake: They should look slightly underdone — they set as they cool!

  • Bigger marshmallows? Cut them into smaller pieces so they blend into the dough better.

  • Messy cookies: Marshmallows may melt out a bit while baking — that’s normal and adds gooey goodness.

  • Want them extra soft? Add 1 extra teaspoon of cornstarch.
