- In a medium bowl, whisk together the flour, baking soda, and salt until evenly combined.
- In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar on medium speed for 2 to 3 minutes. The mixture should look creamy, slightly fluffy, and lighter in color.
- Beat in the eggs one at a time, mixing until each is incorporated. Add the vanilla and scrape down the sides and bottom of the bowl.
- Mix the flour mixture into the wet ingredients on low speed just until a thick dough forms. Stop when only a few small flour streaks remain.
- Reserve 1/2 cup (25 g) of the mini marshmallows for topping. Fold the semisweet chocolate chips, chopped milk chocolate, graham cracker pieces, and remaining 1 cup (50 g) marshmallows gently into the dough.
- Cover the bowl and refrigerate for 1 hour. The dough should feel firm enough to scoop and hold a tall mound.
- Preheat the oven to 350°F (175°C). Line two large baking sheets with parchment paper.
- Scoop approximately 3 tablespoons of dough, about 3 ounces (85 g), per cookie. Shape each portion into a tall mound rather than a flat ball.
- Place 6 to 8 dough portions on each prepared baking sheet, leaving at least 3 inches (7.5 cm) between them.
- Bake one sheet at a time on the center rack for 9 minutes. The cookies should have spread slightly, but the centers will still look underbaked.
- Carefully remove the pan from the oven: Press several pieces of the reserved mini marshmallows into the top of each cookie. Add optional extra chocolate chips and graham cracker pieces at this stage, if using.
- Return the cookies to the oven and bake for another 3 to 5 minutes. The edges should be golden and set, while the centers remain soft. The marshmallows should look puffed and lightly toasted in spots.
- Immediately after baking, use the edge of a large round cookie cutter or spoon to gently nudge any uneven edges into a round shape. Do this while the cookies are still very soft.
- Let the cookies stand on the hot baking sheet for 10 minutes. The centers will continue setting as they cool.
- Transfer the cookies carefully to a wire rack and cool for another 20 minutes. Repeat with the remaining dough.
