These s’mores cookies put a graham cracker, milk chocolate and a whole marshmallow beneath a thick chocolate chip cookie topping. The result is a large, shareable cookie with crisp edges and a soft middle, baked in the oven without a campfire. Chilling the dough gives you time to arrange the bases and helps the butter stay firm enough to hold its shape around the filling.

Why This Recipe Works
The layers in s’mores cookies give a crisp graham base, soft chocolate and a melted marshmallow center. Brown sugar keeps the cookie chewy, while white sugar helps the edges brown. Cover the marshmallow completely so it cannot expand through a thin gap before the dough sets.
Ingredients for S’Mores Cookies
For s’mores cookies, break four full graham sheets into eight halves. Share both chocolate bars among them. Use butter that is soft but still holds its shape, pack the brown sugar, and level the flour. All the dough makes eight jumbo portions.
Cookie Dough
- 1 cup unsalted butter, softened
- 1 cup dark brown sugar, packed
- 1/2 cup white sugar
- 2 large eggs, room temperature
- 1 teaspoon vanilla extract
- 3 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon kosher salt
- 1/2 cup semisweet chocolate chips
- 1/2 cup bittersweet chocolate chips or chunks
Toppings
- 4 full graham cracker sheets, broken into eight halves
- 2 bars milk chocolate, divide evenly among eight cookies; about two small sections per base
- 8 large marshmallows
How to Make S’Mores Cookies
1. Cream and combine. Beat the butter with both sugars until the mixture looks lighter and evenly creamy. Add the eggs and vanilla, scraping the bowl so the batter has no unmixed butter at the bottom. Whisk the flour, soda and salt separately; this spreads the small quantities through the flour before they reach the wet mixture. Stir only until the flour disappears, then fold in the chocolate chips.
2. Chill before shaping. Refrigerate the dough for 30 minutes. This is an actual waiting stage, separate from preparation, and it can take longer if the butter was very warm. For s’mores cookies, dough that feels firm but workable is easier to drape around the filling. During the wait, line two baking sheets with parchment and heat the oven to 350°F. Leave plenty of space for the large portions to spread.
3. Build eight covered mounds. Arrange four cracker halves on each sheet. Share the chocolate bars among all eight bases, add one large marshmallow to each, then divide every bit of dough into eight equal portions. Flatten a portion between your hands and cover its mound, pressing the dough down around the marshmallow. Keep the cracker underneath intact, and close thin gaps in the dough before the trays go into the oven.
4. Bake and let the layers settle. Bake for 12–15 minutes, looking for golden edges and a cookie surface that has set rather than remaining glossy and raw. Oven differences and thick portions can require longer; check the dough as well as its color. If both trays fit with good airflow, bake together and rotate their positions as needed. Let the cookies rest on their sheets for about 10 minutes, until they can be lifted without the filling slipping out.
How to Serve
Serve s’mores cookies after their brief cooling period, while the chocolate is still soft but the cookie can be handled. A spatula helps move these large portions onto plates without breaking the graham base. Cut them in half for a dessert platter if smaller portions suit your guests, and offer milk, coffee or tea alongside. The marshmallow becomes less stretchy as it cools, which is normal.
To make s’mores cookies ahead, refrigerate the covered dough for up to 48 hours and assemble the layers close to baking. Keep the crackers dry and separate until then. Very firm dough can soften briefly on the counter until it is workable; do not melt it to speed up shaping.
Storage and Reheating
Cool s’mores cookies before covering them so trapped steam does not soften the cracker further. Keep them airtight at room temperature for up to three days for best quality, with parchment between stacked layers. Freeze cooled cookies individually, then bag them for up to two months. Thaw covered at room temperature. A brief gentle warming makes the chocolate softer again; watch closely because marshmallow filling can become very hot.

Tips and Variations
- Pack the brown sugar, but spoon flour lightly into its cup and level it. These ingredients need different measuring techniques.
- Use large marshmallows for the stated eight-cookie yield. Loose miniature marshmallows are harder to keep enclosed in the dough.
- Choose parchment rather than an unlined tray; any escaped marshmallow is easier to remove once it has cooled.
Frequently Asked Questions
Why did the marshmallow leak?
A thin gap opens as the marshmallow expands. Cover the filling fully and let escaped marshmallow cool before lifting.
Are these small cookies?
No. Divide all the dough among eight cracker halves for jumbo cookies. Cut a baked cookie if you want smaller servings.
Can I change the chocolate?
Milk chocolate suits the center; darker chocolate gives less sweetness. Keep the filling shared evenly across all eight bases.
How can I tell the dough is chilled enough?
It should hold a flattened shape without feeling greasy. Give very soft dough more refrigerator time before covering the filling.
Why is the cracker softer the next day?
Moisture moves into the cracker during storage. The clearest crisp-and-soft contrast comes soon after baking.

S’mores Cookies
Ingredients
Cookie Dough
- 1 cup unsalted butter softened
- 1 cup dark brown sugar packed
- 1/2 cup white sugar
- 2 large eggs room temperature
- 1 teaspoon vanilla extract
- 3 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon kosher salt
- 1/2 cup semisweet chocolate chips
- 1/2 cup bittersweet chocolate chips or chunks
Toppings
- 4 full graham cracker sheets broken into eight halves
- 2 bars milk chocolate divide evenly among eight cookies; about two small sections per base
- 8 large marshmallows
Instructions
- Beat 1 cup butter with the brown and white sugars until creamy. Mix in the eggs and vanilla. Whisk flour, baking soda and salt separately, add to the butter mixture, and mix just until combined. Fold in both kinds of chocolate chips.
- Cover and refrigerate for at least 30 minutes, until firm enough to shape. Heat the oven to 350°F and line two baking sheets with parchment.
- Place four graham cracker halves on each tray, spaced well apart. Divide the milk chocolate equally among eight bases and put one marshmallow on each. Divide the entire dough into eight equal pieces; flatten each and mold it over its filling, closing gaps.
- Bake both sheets for 12–15 minutes if they fit with airflow, rotating as needed, until edges are golden and the dough surface is set. Continue briefly if dough is still raw-looking. If baking one sheet at a time, keep the other chilled and add a second baking cycle.
- Leave on the baking sheets for about 10 minutes, until firm enough to transfer with a spatula. Serve warm or cool completely for storage.
Notes
- Keep cooled cookies airtight for up to three days for best texture.
- Freeze baked cookies for up to two months. An additional oven batch increases the stated time.
