These S’mores Crumbl cookies are big, bakery-style cookies with a buttery graham-style cookie base, plenty of chocolate chips, and a toasted marshmallow finish - aka a cozy s’mores cookie you can make at home.
Preheat oven to 350°F (180°C). Line a baking sheet with parchment paper.
In a medium bowl, whisk together flour, cinnamon, baking soda, and salt.
In a large bowl, cream butter and brown sugar until light and fluffy, 2–3 minutes.
Add the egg, then mix in milk, honey, and vanilla until combined.
Gradually stir in the dry ingredients until a soft cookie dough forms. Do not overmix.
Fold in the chocolate chips evenly.
Chill the dough for 30 minutes (important for thick cookies).
Scoop dough into 9 large portions (about 50–60 g / 3 tbsp each). Roll into balls and place on the tray, leaving 3 inches (7 cm) between cookies.
Bake 12–14 minutes, until edges are lightly golden and centers are just set (they firm as they cool).
Remove from the oven. Press 2 large marshmallows into the center of each cookie. Toast with a kitchen torch. Sprinkle with graham crumbs if desired.
No torch? Broil in 10–20 second bursts, watching constantly.
Notes
For smaller cookies: make 18 cookies, bake 9–11 minutes.
Chocolate choice: semi-sweet is balanced; milk chocolate tastes most like classic s’mores.
Storage
Room temp: airtight container 2–3 days (marshmallow tops soften).
Fridge: up to 5 days; bring to room temp before serving.
Freezer (best method): freeze cookie dough balls, then bake from frozen (add 1–2 minutes). I don’t recommend freezing finished cookies with toasted marshmallows.
