S'mores Stuffed Cookies

This s'mores stuffed cookies recipe brings all the joy of campfire s'mores and warm chocolate chip cookies together in one crave worthy treat, perfect when you want a quick dessert upgrade in about an hour. Gooey marshmallow and melted chocolate nestle inside a golden brown, chewy cookie shell, making these irresistible for parties, family nights, or when you need a comforting handheld dessert beyond ordinary chocolate chip cookies.

I baked these easy s'mores stuffed cookies after a summer BBQ when we had extra marshmallows, and the batch disappeared before the cookies even cooled. The first gooey bite instantly became a family favorite among both kids and adults during fun weekends when we crave something nostalgic, extra chocolatey, and just a little bit over the top.

Gather Your Ingredients

• All purpose flour for s'mores cookies: Essential for structure; spoon and level for accuracy, and you can swap gluten free blend with dough chilling for stability
• Baking soda: Helps cookies puff up and stay soft; thoroughly whisk for even rise in each batch
• Fine sea salt: Sharpens flavors and balances sweetness, plus enhances chocolate and marshmallow notes
• Unsalted butter: Creates decadent richness and chewy texture; high quality butter gives the best flavor, or use salted and adjust salt in the recipe
• Packed light brown sugar: Gives a caramel note and chew; contrast with granulated sugar for crisp edges
• Granulated sugar: Balances sweetness and promotes browning for golden brown cookie tops
• Pure vanilla extract: Adds warmth and depth; bakery style flavor comes from real vanilla, not imitation
• Large eggs: Bind the dough, keeping cookies moist and soft without crumbling
• Semi sweet chocolate chips: Melt into gooey pockets; dark or milk chocolate can substitute for different s'mores flavor profiles
• Graham cracker sheets: Key for the classic crunch; choose ones that hold shape for stacking, or sub gluten free graham crackers
• Full size marshmallows: Ensures gooey, stretchy centers; use mini marshmallows if needed, just increase the handful per cookie
• Snack size Hershey's chocolate bars: Classic s'mores taste; change them out for fun size bars, peanut butter cups or leftover holiday chocolate

How to Make S'mores Stuffed Cookies

Preheat Your Oven and Line Baking Sheets:

Heat oven to 375 degrees and lay parchment paper on your baking sheets. This prevents sticking and supports even baking so your cookies get golden brown without burning on the bottom.

Mix Dry Ingredients for a Classic Cookie Base:

Whisk together the flour, baking soda, and sea salt in a medium bowl. Combining these first ensures even lift and seasoning throughout every cookie for bakery style texture.

Cream Butter and Sugars for Chewy Texture:

In a large mixing bowl, beat butter with brown and granulated sugars until creamy, about 2 to 3 minutes on medium. This step creates air pockets that result in thick, chewy cookies and an irresistible crumb.

Add Eggs and Vanilla for Flavor Depth:

Crack in both eggs and pour in vanilla extract. Mix on low until just combined, being careful not to overbeat, so your dough stays soft and doesn't turn tough after baking.

Incorporate Dry Mixture for Soft Dough:

Gradually add dry blend to the wet ingredients, stirring just until flour disappears. Avoid overmixing so cookies turn out tender with a slightly crisp edge.

Fold in Chocolate Chips for Melted Centers:

Stir in all chocolate chips with a spatula for an even distribution; if your dough feels sticky, chill in the fridge for 10 minutes before shaping to keep cookies thick when baked.

Shape and Flatten Cookie Dough Bases:

Scoop out 3 to 4 tablespoons of dough per cookie on parchment lined sheets. Flatten each to about a quarter inch using fingertips or the back of a spoon, dusting fingers with flour to prevent sticking.

Assemble the S'mores Center for Maximum Gooeyness:

Add half a graham cracker, pieces of Hershey's bar, and at least two marshmallow halves to the base. Layer ingredients for optimal stretch and chocolate flow in every bite.

Seal With More Cookie Dough for Thick Cookies:

Top each stack with another scoop of dough and gently pinch all edges together to fully encase the filling. Sealing well ensures marshmallow stays inside for gooey, bakery style results.

Chill for Thick, Bakery Style Cookies:

Chill assembled cookies on the sheet for 15 to 30 minutes in the fridge. Cold dough bakes up thick and reduces spread, keeping all the filling inside.

Bake Until Golden and Let Cool:

Bake at 375 degrees for 13 to 15 minutes, watching for edges to turn golden and centers to puff. Cool on the sheet at least 5 minutes to allow the cookies to finish setting and the marshmallow to firm up inside.

The first time I tested this recipe, I forgot to pinch one of the cookies tightly and the marshmallow bubbled out—it taught me to always double check each edge. My kids love sneaking extra marshmallow and bits of chocolate into their cookies, and every batch becomes a fun family project with a sweet surprise center. These cookies deliver more protein than most desserts and store great for meal prep or late night cravings.

Smart Swaps and Variations

To change up your s'mores stuffed cookies, try dark or milk chocolate instead of semi sweet chips for a twist on the flavor. Use gluten free flour and chill the dough longer if celiac friendly baking is needed. Mini peanut butter cups, fun size candy bars, or fruit marshmallows can be substituted for a custom treat, and vegan options work too with plant based butter, chocolate, and fluffy marshmallows—each variation brings its own delicious spin.

How to Store and Reheat S'mores Stuffed Cookies

Keep baked s'mores stuffed cookies soft by storing them at room temperature in a single layer inside an airtight container for up to three days, or freeze them layered with parchment paper for up to three months. For fresh, gooey centers, microwave each cookie for 10 to 15 seconds before eating. For make ahead prep, freeze unbaked cookies, then bake straight from the freezer, adding two extra minutes to the bake time for perfect results whenever the craving strikes.

What to Serve with S'mores Stuffed Cookies

S'mores stuffed cookies shine as the star of the dessert table but pair beautifully with vanilla ice cream or a glass of cold milk for a nostalgic finish. Set up a s'mores bar with extra marshmallows and graham crackers for parties, or serve mini versions alongside fruit salad or grilled peaches at summer gatherings. Drizzle cookies with chocolate sauce or caramel if you want a decadent touch for birthdays and celebrations.

Nutritional Benefits

S'mores stuffed cookies offer a surprising protein boost from eggs and flour, plus antioxidants from chocolate. Each cookie satisfies sweet cravings and helps with fullness thanks to the blend of carbs and healthy fats, and with easy options for gluten free or dairy free baking, these fit various dietary needs. While indulgent, you control the ingredients and can portion out for your preferences or nutrition goals.

Recipe Success Tips

If your marshmallow leaks out while baking, try pinching the cookie dough seams tighter and ensure your oven temperature is accurate. Flatten dough more before baking if cookies are too thick, or chill the shaped dough longer for thicker results. Always use parchment paper to avoid sticking, and if fillings seep, try mini marshmallows for less expansion and easy cleanup next batch.

This s'mores stuffed cookies recipe always brings the wow factor with every gooey, chocolatey bite. Try your own favorite fillings or let your family help customize each batch for a crave worthy dessert experience you'll want to make again and again.
