If you love the flavors of a classic s’more but want them in an easy, bakery-style cookie, this recipe is for you. These Toasted Marshmallow S’mores Cookies combine a buttery graham cracker cookie base, chunks of milk chocolate folded right into the dough, and perfectly toasted marshmallows baked on top. The result is a cookie that feels nostalgic, indulgent, and ideal for everything from casual weekends to summer gatherings.

Instead of assembling s’mores outdoors or dealing with sticky layers, this recipe brings everything together in one cohesive cookie. Each bite delivers a balance of texture and flavor: crisp edges, soft centers, melted chocolate, and marshmallows that toast rather than disappear into the dough.

These cookies are easy to make, require simple ingredients, and are guaranteed to be a crowd favorite.

Why You’ll Love These S’mores Cookies

This recipe was designed to highlight classic s’mores flavors in a way that’s approachable and reliable. The graham cracker crumbs are mixed directly into the dough, giving every cookie that familiar honey-graham taste. Chopped Hershey’s milk chocolate bars melt into pools instead of staying uniform like chocolate chips, creating varied texture throughout. And by placing the marshmallow halves on top of the dough before baking, they toast beautifully in the oven.

These cookies are:

Thick and bakery-style
Easy to prep ahead of time
Perfect for summer parties, holidays, or gifting
A fun twist on traditional cookies without extra steps

They’re also a great recipe if you want something that feels elevated but still comforting.

Ingredients You’ll Need

For the Graham Cracker Cookie Dough

Unsalted butter, softened
Brown sugar (dark brown sugar adds extra depth)
Granulated sugar
Eggs
Vanilla extract
All-purpose flour
Graham cracker crumbs
Baking soda
Sea salt

For the Mix-Ins & Topping

6 Hershey’s milk chocolate bars, chopped
Large marshmallows, cut in half

Using chopped chocolate bars instead of chocolate chips makes a noticeable difference. The chocolate melts more naturally and creates pockets of chocolate throughout the cookie rather than evenly distributed chips.

How to Make Ultimate S’mores Cookies

1. Make the Graham Cracker Dough

Start by whisking together the flour, graham cracker crumbs, baking soda, and salt. Mixing the crumbs into the dry ingredients ensures the graham flavor is evenly distributed throughout the dough.

In a separate bowl, cream the softened butter with both sugars until light and fluffy. This step is key for achieving a soft interior and slightly crisp edges. Add the eggs one at a time, followed by the vanilla extract, mixing well after each addition.

Gradually add the dry ingredients to the wet mixture and mix just until combined. Overmixing can lead to dense cookies.

Finally, fold in the chopped Hershey’s chocolate bars, making sure the pieces are evenly distributed.

2. Shape and Top the Cookies

Scoop about two tablespoons of dough for each cookie and gently flatten it slightly. Place the dough on a parchment-lined baking sheet, leaving space between each cookie.

Press one halved marshmallow into the top of each dough portion, cut-side down. Keeping the marshmallow visible allows it to toast in the oven while still holding its shape.

3. Chill the Dough

Refrigerate the shaped cookies for at least 30 minutes. Chilling helps control spreading and keeps the cookies thick while baking. This step also helps the marshmallows stay nicely positioned on top.

4. Bake

Preheat your oven to 350°F (175°C). Bake the cookies for 10–12 minutes, until the edges are lightly golden and the centers are just set. The marshmallows should look puffed and lightly toasted.

Once out of the oven, you can sprinkle flaky sea salt if desired. Let the cookies cool slightly before serving.

Tips for the Best S’mores Cookies

Use kitchen shears to cut marshmallows cleanly without sticking.
Don’t skip chilling, it makes a noticeable difference in texture.
Chop chocolate into varied sizes for more texture and melt.
Bake on parchment paper to prevent sticking and ensure even browning.

If your marshmallows brown faster than expected, you can loosely tent the cookies with foil for the last minute of baking.

Make-Ahead & Storage Tips

These cookies are perfect for prepping in advance.

Make Ahead:
You can shape and top the cookies, then refrigerate them for up to 24 hours before baking.

Freezing:
Freeze unbaked dough balls (without marshmallows) for up to 2 months. Add marshmallows just before baking.

Storage:
Store baked cookies in an airtight container at room temperature for up to 3 days. For best texture, enjoy them the same day they’re baked.

When to Serve S’mores Cookies

These cookies are versatile and work for so many occasions:

Summer barbecues
Movie nights
Holiday dessert tables
Bake sales
Homemade gifts

They’re also a great alternative to traditional brownies or chocolate chip cookies when you want something a little different but still familiar.

Frequently Asked Questions

Can I use milk or dark chocolate instead?
Yes. Milk chocolate gives the most traditional s’mores flavor, but dark chocolate works well if you prefer a less sweet cookie.

Can I make these smaller?
You can, but keep in mind that marshmallows will brown faster on smaller cookies. Adjust bake time accordingly.

Why graham cracker crumbs in the dough instead of on top?
Mixing the crumbs directly into the dough ensures consistent flavor in every bite and prevents crumbs from burning.
