Ingredients

Scale
  • 2 1/4 cups (280g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup (226g) unsalted butter, softened
  • 3/4 cup (150g) brown sugar, packed
  • 1/2 cup (100g) granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup (about 8 sheets) graham crackers, coarsely crushed
  • 1 cup (170g) milk chocolate chips or chunks
  • 1 cup (50g) mini marshmallows
  • 1/2 cup (120g) marshmallow fluff or creme
  • Flaky sea salt, for sprinkling (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
  2. In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
  3. In a large bowl, beat softened butter, brown sugar, and granulated sugar with an electric mixer until light and fluffy, about 2-3 minutes.
  4. Beat in eggs, one at a time, then add vanilla extract. Scrape down the bowl as needed.
  5. Gradually add dry ingredients to the wet mixture, mixing just until combined.
  6. Gently fold in crushed graham crackers, chocolate chips or chunks, and mini marshmallows with a spatula.
  7. Drop spoonfuls of marshmallow fluff over the dough and gently fold and swirl with a spatula—do not fully mix in.
  8. Scoop 2-tablespoon mounds of dough onto prepared baking sheets, spacing 2 inches apart. The dough will be sticky; use nonstick spray on your scoop if needed.
  9. Sprinkle each mound with a pinch of flaky sea salt, if using.
  10. Bake for 10-12 minutes, until edges are golden and centers look slightly underbaked.
  11. Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
  12. Repeat with remaining dough, allowing baking sheets to cool between batches if needed.

Notes

For best results, use fresh marshmallows and avoid overbaking for a gooey center. If your dough is sticky or your kitchen is warm, chill the dough for 15 minutes before scooping. Swirl, don’t fully mix, the marshmallow fluff for signature gooey streaks. Cookies are nut-free but always check packaging for cross-contamination if allergies are a concern. Store in an airtight container for up to 4 days or freeze for up to 2 months.
