This S’mores Cookie recipe takes a giant chocolate chip cookie and stuffs it full of melty milk chocolate, gooey marshmallows, and a bit of graham cracker crunch.
I have a really fun, *really* decadent dessert recipe for you today, a giant S’mores Cookie.
Gooey S’mores Cookie for Two
For this recipe, I took my Giant Chocolate Chip Cookie recipe and stuffed a s’more inside because sometimes you just need more good things in the world.
The result is an already outrageously good cookie that is now filled with melty milk chocolate, gooey marshmallows, and a bit of graham cracker crunch. (It’s kind of spectacular.)

The baked cookie’s about six-inches across, so it’s definitely built for sharing. It generously serves two, but for smaller kids or adults with less of a sweet tooth, you could probably get three servings out of it.
How do you make a s’mores cookie?
1. Start with your cookie dough base, and then take slightly less than half the dough and form it into a disk about 2 1/2-inches across.
2. Place half a graham cracker on top followed by chocolate and either a handful of mini marshmallows or a regular-sized marshmallow cut in half lengthwise, arranged with the cut-sides on the chocolate.
A Note on Chocolate: I specifically call for Hershey’s chocolate pieces in these cookies because I consider it part of that classic S’mores flavor, but you can use whatever chocolate bar you prefer. I imagine a peanut butter cup would be *amazing* or a caramel or raspberry jam-filled chocolate square…
3. Finally, take the rest of the cookie dough, shape it into a second disk, and press it over the top of the s’more, smooshing down the sides so the graham cracker and chocolate are covered. Then bake and eat. (Also don’t forget to share!)

Tips and Recipe Notes
- To avoid having to split a whole egg, this cookie is made with a single egg yolk. If you are sensitive to the taste of egg yolk in baked goods, you can replace the egg yolk with 1 tablespoon of a whisked whole egg.
- Sometimes people use an entire egg when a recipe calls for just a yolk or an egg white, and sometimes it works fine. DO NOT do that with this recipe. It will be far too much liquid and you will end up with a cookie puddle.
- For ideas on what to do with the leftover egg white, check out my post What to Do With Leftover Egg Whites.
S'mores Cookie (For Two)
- 2 tablespoons (28g) butter melted and slightly cooled
- 2 tablespoons (25g) brown sugar
- 1 heaping tablespoon (18g) granulated sugar
- 1/4 teaspoon vanilla extract
- 1 large egg yolk OR 1 tablespoon whisked whole egg
- 1/3 cup (40g) all-purpose flour measured by weight or using the spoon and sweep method*
- 1/8 teaspoon baking soda
- 1/8 teaspoon salt if using salted butter, cut salt by half
- 1/4 cup (1.5oz) semi-sweet chocolate chips
- 1/2 graham cracker
- 3 pieces/segments of a Hershey's bar or chocolate of choice
- 9 mini marshmallows or 1 full-size marshmallow cut in half lengthwise
- Preheat your oven to 350°F and line a baking sheet with parchment paper or a silicone baking mat.
- In a small bowl, whisk together melted and slightly cooled butter, brown sugar, and granulated sugar. Add vanilla extract and egg yolk, and mix well.
- Add flour, baking soda, and salt, and use a spoon to stir until combined.
- Stir in chocolate chips.
- Scoop out slightly less than half the dough and shape into a disk about 2 1/2 inches across (about the width of a graham cracker). Place disk on prepared baking sheet.
- Set graham cracker half on top of the dough, followed by chocolate pieces and then marshmallows.
- Shape remaining dough into a disk and press it over the top of the marshmallows. Smoosh the dough down so the chocolate and graham crackers are completely covered.
- Bake for 11 to 14 minutes, until the top of the cookie looks mostly set and edges are just starting to brown. Allow to cool on the baking sheet for 5 minutes and enjoy!
