These s’mores cookies are everything I love about a summer campfire wrapped up in one ridiculously good cookie. They’re packed with graham crackers, melty chocolate, and gooey marshmallows tucked right inside.

I’m a perfectly golden, never burned marshmallow girl. If my marshmallow catches fire, we’re starting over. I didn’t wait all year for camping season to eat charcoal. My family grew up camping. It’s what we did in the summer, in the backyard, girls camp and boys camp, and for spring break.

My mom is an amazing camper and can bust out the most amazing Dutch oven, campfire, reflector oven and even tin foil dinners. But the real star of the show was always dessert. Her peach cobbler in a Dutch oven is still one of the best things ever about my childhood, but right up there with it is a good s’more. Nowadays I’m not super into s’mores but put it in a cookie and I’m allllll over it!

How to Make S’mores Cookies

These gooey s’mores cookies start with a soft graham cracker cookie dough and are stuffed with marshmallows and chocolate for the ultimate campfire cookies.

Make the Cookie Dough: In a medium bowl, whisk together the flour, graham cracker crumbs, baking soda, baking powder, cornstarch, and salt. In the bowl of a stand mixer, beat the butter and sugars until light and creamy. Add the egg and vanilla and mix until smooth. Gradually add the dry ingredients, mixing just until combined. Fold in the chocolate chips and chopped Hershey’s chocolate.
Chill the Dough: Cover and refrigerate the dough for at least 20 minutes or up to overnight for thicker, chewier cookies.
Stuff the Cookies: Heat the oven to 350°F. Scoop the dough into balls and flatten each slightly. Place half of a marshmallow in the center, wrap the dough around it, and roll into a smooth ball.
Bake: Place each cookie dough ball on top of a graham cracker half and bake for 10-15 minutes, depending on the size of your cookies and whether the dough was chilled.
Finish and Cool: As soon as the cookies come out of the oven, press additional pieces of Hershey’s chocolate into the tops. For an extra campfire feel, lightly toast any exposed marshmallow with a kitchen torch. Let cool on the baking sheet for a few minutes before transferring to a cooling rack.

Variations and Substitutions

Chocolate: Use milk chocolate chips instead of semi-sweet or dark chocolate bars for a richer flavor.

Extras: Add chopped toffee bits for extra caramel flavor or mix in mini chocolate chips for even more chocolate.

Flavor: Sprinkle flaky sea salt over the tops after baking.

Texture: Add chopped pecans or walnuts for crunch.

Cracker: Use cinnamon graham crackers for extra warmth, or feel free to skip the cracker on the bottom altogether. My kids prefer it without the cracker.

How to Store S’mores Cookies

Store cookies in an airtight container at room temperature for up to 4 days.

For extra gooey marshmallows, warm cookies in the microwave for 10-15 seconds before serving.

Freeze baked cookies for up to 3 months.
