Ingredients You’ll Need

Chocolate Cookie Dough

• 12 tablespoons unsalted butter, room temperature — Provides richness and helps create a soft, chewy cookie texture.
• 1 cup packed light brown sugar — Adds moisture, caramel notes, and a deeper sweetness.
• ¼ cup granulated sugar — Helps create balanced sweetness and slightly crisp edges.
• 1 large egg, room temperature — Adds moisture and binds the dough ingredients together.
• 1 large egg yolk, room temperature — Creates a richer, softer cookie texture by adding extra fat.
• 2 teaspoons vanilla extract — Enhances the chocolate flavor and adds aromatic sweetness.
• 1½ cups + 3 tablespoons all-purpose flour — Provides structure while maintaining a tender cookie texture.
• ⅔ cup unsweetened Dutch cocoa powder — Creates a deep chocolate flavor and fudgy consistency.
• ½ cup mini semi-sweet chocolate chips — Adds melted chocolate pockets throughout the cookies.
• 1 teaspoon fine sea salt — Balances sweetness and intensifies the chocolate flavor.
• 1 teaspoon baking soda — Helps the cookies spread and develop a tender texture.
• ½ teaspoon baking powder — Adds slight lift and prevents overly dense cookies.

S’mores Filling and Toppings

• 22 large marshmallows — Creates the gooey melted center that defines the s’mores experience.
• Graham cracker chunks and crumbs — Adds crunch and the classic toasted cracker flavor.
• Dark chocolate bar pieces — Provides a rich chocolate topping and completes the s’mores profile.

Step-by-Step Instructions

1. Cream the Butter and Sugars

Beat the softened butter, brown sugar, and granulated sugar together for approximately 3 minutes until the mixture becomes light, fluffy, and creamy. This step incorporates air into the dough and improves the final cookie texture.

2. Add Eggs and Vanilla

Mix in the egg, egg yolk, and vanilla extract until just combined. Avoid overmixing at this stage to maintain a tender cookie structure.

3. Combine the Dry Ingredients

Add the flour, cocoa powder, chocolate chips, salt, baking soda, and baking powder to the bowl. Mix until the dough forms and all ingredients are incorporated, being careful not to overwork the mixture.

4. Chill the Cookie Dough

Cover the bowl and refrigerate the dough for 1 hour. Chilling firms the butter, making the dough easier to handle and preventing excessive spreading during baking.

5. Shape the Cookie Dough

Use a standard two-tablespoon cookie scoop to portion the dough onto a parchment-lined baking sheet. Flatten each dough portion slightly with your hands to prepare it for stuffing.

6. Add the Marshmallow Center

Place one large marshmallow in the center of each flattened dough piece, then fold the cookie dough around it. Leave only the top portion of the marshmallow slightly visible for the signature s’mores appearance.

7. Add Graham Crackers and Chill Again

Place the stuffed cookies back onto the baking tray and sprinkle with crushed graham crackers and crumbs. Refrigerate the prepared cookies for another 1–2 hours to help them hold their shape.

8. Bake the Cookies

Preheat the oven to 350°F (180°C) and bake cookies spaced about 3 inches apart for 10–11 minutes. The cookies are ready when the marshmallow is puffed and the cookie dough begins to crack around the center.

9. Finish and Cool

Immediately after baking, use a round cookie cutter to gently reshape the edges into perfect circles. Place a square of dark chocolate on top, then allow the cookies to cool completely before removing them from the tray.

Recipe Notes & Tips

• Measure Flour Properly — Spoon flour into measuring cups and level it off instead of scooping directly to avoid adding too much flour and creating dry cookies.
• Do Not Skip Chilling — Cold dough is essential for easy stuffing and prevents cookies from spreading too much while baking.
• Use a Damp Towel While Shaping — Cookie dough can become sticky during stuffing; wiping your hands between cookies makes handling easier.
• Use Room Temperature Ingredients — Butter, eggs, and yolks blend more evenly, creating a smoother dough.
• Leave Space Between Cookies — These cookies spread and expand, so keep at least 3 inches between each cookie on the baking tray.
• Remove Carefully After Baking — Melted marshmallow can stick to parchment; use a spatula to gently lift cookies if needed.

Perfect Pairings

• Cold Milk — A classic pairing that balances the richness of the chocolate and marshmallow.
• Vanilla Ice Cream — Creates an indulgent chocolate s’mores dessert combination.

Storage & Serving Tips

• Room Temperature Storage — Store cookies in an airtight container with parchment paper between layers for 1–2 days.
• Serve Slightly Warm — Reheat briefly before serving to restore the melted chocolate and marshmallow texture.
• Avoid Stacking Without Protection — Marshmallow centers can become sticky; parchment prevents cookies from sticking together.
• Freeze Dough Portions — Prepared cookie dough balls can be frozen and baked later for fresh cookies on demand.

Creative Variations to Try

• Peanut Butter S’mores Cookies — Add peanut butter chips or a peanut butter filling for a richer flavor.
• Triple Chocolate Version — Replace some chocolate chips with chunks of milk or dark chocolate.
• Salted Caramel S’mores Cookies — Add caramel pieces and flaky sea salt for a sweet-salty twist.
• Mint Chocolate S’mores Cookies — Add mint extract and chocolate mint pieces for a refreshing variation.

Troubleshooting Common Issues

• Cookies Spread Too Much — The dough may not be cold enough; chill longer before baking.
• Marshmallow Leaks Completely — Make sure the dough fully surrounds the marshmallow except for the top portion.
• Cookies Are Dry — Too much flour or overbaking can remove moisture; measure flour carefully and bake only until the edges set.
• Dough Is Too Sticky to Handle — Chill the dough longer or lightly dampen your hands while shaping.

Why This Recipe Works

This recipe works because it uses careful temperature control and ingredient balance to create a cookie with contrasting textures. The combination of butter, brown sugar, and egg yolk creates a moist and chewy chocolate cookie base, while Dutch cocoa powder provides intense chocolate flavor without adding extra sweetness. Chilling the dough allows the butter to firm up, preventing excessive spreading and helping the cookies maintain their stuffed shape. The marshmallow center melts during baking, creating the signature gooey s’mores effect, while graham cracker pieces add crunch and nostalgic flavor. The final dark chocolate topping reinforces the chocolate profile and creates a visually appealing finish. With approximately 250–350 calories per cookie, these treats are best enjoyed as an occasional indulgent dessert.

Final Thoughts

Double Chocolate S’mores Cookies bring the magic of a campfire dessert into a rich, homemade cookie format. Their combination of fudgy chocolate dough, melted marshmallow, crunchy graham crackers, and dark chocolate creates a memorable dessert experience that works for both casual treats and special occasions. For a lighter option, consider reducing the chocolate toppings, using smaller cookie portions, or pairing them with fresh fruit to balance the sweetness while still enjoying the classic s’mores flavors.
