If you've ever wanted campfire S'mores in cookie form, this is it. These chocolate cookies are loaded with marshmallows, chocolate chips, and topped with actual pieces Hershey bars and graham cracker crumbs while they're still warm. It's everything you love about S'mores, but in a chewy cookie you can make year-round in your kitchen.

What to know about these cookies: The cookies bake just until set, then you add the toppings while they're hot. The residual heat melts the Hershey bar and softens the marshmallows, giving you that authentic S'mores experience without a campfire.

How To Make Chocolate S'mores Cookies
The printable recipe card is also at the end of the post.
Yields: 10-12 cookies
Time: 10 minutes prep, 11 minutes baking
What You Need: ½ cup butter, ¾ cup white sugar, ¼ cup packed brown sugar, 1 egg, 1 teaspoon vanilla extract, 1 cup all-purpose flour, ⅓ cup unsweetened cocoa, ½ teaspoon baking soda, 1 teaspoon salt, ¾ cup chocolate chips, 1 cup mini marshmallows, Hershey Bars.
Preheat your oven to 350 degrees and line cookie sheets with parchment paper. In a large bowl, cream together ½ cup butter, ¾ cup white sugar, and ¼ cup packed brown sugar with a hand mixer for about 2 minutes. Add 1 egg and 1 teaspoon vanilla extract, mixing until smooth and incorporated. In a separate medium bowl, whisk together 1 cup all-purpose flour, ⅓ cup unsweetened cocoa, ½ teaspoon baking soda, and 1 teaspoon salt.
Gradually add the dry ingredients to the wet ingredients, stirring with a wooden spoon. When the dry mix is almost incorporated, fold in ¾ cup chocolate chips and 1 cup mini marshmallows, mixing just until evenly distributed without over-mixing. Using a cookie scoop, drop oversized portions of dough onto the prepared cookie sheet, dividing the dough into 12 cookies, and press each one down slightly.
Bake for 10-12 minutes, then immediately top each warm cookie with 1 rectangle of Hershey bar, a few extra marshmallows, and a sprinkle of graham cracker crumbs (you'll need ¼ cup total and 1-2 full-sized Hershey bars for all the cookies).

Tips for Success
- Don't over bake. These cookies continue cooking on the hot pan after you remove them from the oven. If you bake until they look "done," they'll be dry.
- Top them while hot. The chocolate and marshmallows need that residual heat to get gooey goodness
- Use mini marshmallows in the dough. Regular marshmallows are too big and create weird pockets. Minis distribute better.
- Make them the same size. Using a cookie scoop ensures even baking and no burnt edges with raw centers.
Storage
These are best the day they're made, but you can store them in an airtight container for a couple of days. The marshmallows will firm up, but a quick 10-second microwave zap brings back some of that melty magic.
