Best S’mores Cookies Recipe – Soft, Chewy & Loaded with Chocolate

My son had a bag of marshmallows left over from a camping trip that never happened the weather turned, the trip got cancelled, and a half-empty bag sat in the pantry for weeks. I didn’t want to waste them, so I started digging through the cabinet for graham crackers and chocolate bars. That’s how this easy s’mores cookies recipe was born.

He took one bite, watched the gooey marshmallow stretch from the cookie to his mouth, and said, “This is better than the real thing.” Now it’s the homemade s’mores cookies recipe he asks for every time friends come over, rain or no rain.

Why You’ll Love This Recipe

These chewy s’more cookies are a homemade twist on classic s’mores cookies, made with graham cracker crumbs, semisweet chocolate chips, and chunks of Hershey’s milk chocolate folded into the dough. The dough comes together in one bowl with a 30-minute chill, then bakes in just 14 minutes. Each cookie is topped with a marshmallow that toasts golden in the oven, giving you that campfire flavor without needing a fire. It’s an easy dessert cookie that’s perfect for bake sales, lunchboxes, or a quick after-dinner treat.

Ingredients for Gooey Marshmallow Chocolate Cookies

Dry Ingredients

• 3 cups (375 g) all-purpose flour – the base of the dough; spoon into the cup and level it off so the cookies don’t turn out dry.
• ½ cup (45 g) graham cracker crumbs – gives these graham cracker cookies their signature toasty, slightly sweet flavor.
• 1 tsp baking soda – helps the cookies spread just enough while staying thick and chewy.
• 1 tsp salt – balances the sweetness from sugar, chocolate, and marshmallows.

Wet Ingredients

• 1 cup (227 g) unsalted butter, room temperature – creamed with sugars for a soft, tender texture.
• 1½ cups (330 g) light brown sugar – adds moisture and keeps these cookies soft for days.
• ½ cup (100 g) granulated sugar – gives the edges a light crispness.
• 2 large eggs, room temperature – bind the dough together; cold eggs can make the butter seize.
• 2 tsp vanilla extract – enhances the chocolate and graham flavor.

Mix-Ins

• 1 cup (180 g) semisweet chocolate chips – create melty pockets of chocolate throughout the dough.
• 3 Hershey’s milk chocolate bars, roughly chopped – rich chocolate chunks for that classic s’mores cookies flavor.
• 4 graham cracker sheets, roughly chopped – add crunch and texture.
• 26 marshmallows – one per cookie for that gooey toasted topping.

For Topping

• 1 Hershey’s milk chocolate bar, roughly chopped – pressed on top after baking for extra melt.
• ½ cup (90 g) semisweet chocolate chips – added while warm for a bakery-style finish.

How to Make S’mores Cookies (Step by Step)

1. Whisk the Dry Ingredients

In a medium bowl, whisk together the flour, graham cracker crumbs, baking soda, and salt. Set this aside while you prepare the wet ingredients.

2. Cream the Butter and Sugars

In a large bowl, beat the room-temperature butter with brown sugar and granulated sugar until light and fluffy, about 2–3 minutes. I rushed this step once with cold butter and ended up with greasy, flat cookies — don’t skip the room-temperature butter.

3. Add the Eggs and Vanilla

Beat in the eggs one at a time, then mix in the vanilla extract until fully combined.

4. Combine Wet and Dry Mixtures

Gradually add the flour mixture to the butter mixture, mixing on low speed just until no dry streaks remain. Overmixing can make the cookies tough, so stop as soon as it comes together.

5. Fold in Chocolate and Graham Crackers

Using a spatula, fold in the semisweet chocolate chips, chopped Hershey’s bars, and graham cracker sheets until evenly distributed throughout the dough.

6. Chill the Dough

Cover the bowl and refrigerate for at least 30 minutes. This step is important — chilled dough holds its shape and creates thick, chewy cookies instead of thin, crispy ones.

7. Preheat and Scoop

Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. Scoop dough into golf ball-sized portions (about 3 tablespoons each) and place them a few inches apart.

8. Bake and Add Marshmallows

Bake for 10 minutes, then remove the tray and press one marshmallow into the center of each cookie. Return to the oven for another 3–4 minutes until marshmallows are golden and puffy and edges are set.

9. Add the Finishing Touches

Immediately press a piece of chopped Hershey’s bar onto each marshmallow and sprinkle extra chocolate chips on top. The heat will melt everything into a gooey topping.

10. Cool and Serve

Let cookies rest on the pan for 5 minutes before transferring to a wire rack. Best enjoyed warm when the marshmallow and chocolate are still soft and gooey.

Expert Tips for Perfect S’mores Cookies

Don’t Skip the Chill Time

After baking a batch straight from the mixing bowl, I ended up with cookies that spread into thin, crispy discs. Thirty minutes in the fridge keeps the dough firm enough to bake up thick and chewy.

Use Room-Temperature Eggs and Butter

Cold ingredients don’t blend smoothly, and I’ve had batches come out greasy because the butter never fully creamed with the sugar.

Add Marshmallows Halfway Through Baking

I tried putting marshmallows on raw dough once, and they melted completely flat and disappeared into the cookie. Adding them partway through gives a toasted top that still holds its shape.

Use Roughly Chopped Chocolate Bars

Instead of using chips only, chop chocolate bars into uneven chunks. This creates big melty pools of chocolate that make these taste like bakery-style s’mores cookies.

Measure Flour Properly

Scoop flour into the measuring cup with a spoon, then level it off with a knife. Scooping directly from the bag packs in extra flour and leads to dry, crumbly cookies.

Watch the Bake Time After Adding Marshmallows

Marshmallows can go from perfectly toasted to burnt within a minute or two, so stay near the oven during the final stretch.

Add Extra Crunch for Texture

For easy oven baked s’mores cookies with extra crunch, save a few chopped graham cracker pieces to press on top of the marshmallow before it cools.

Ingredient Substitutions

No Graham Cracker Crumbs?

Crush extra graham cracker sheets in a zip-top bag with a rolling pin the texture will be slightly coarser, but the flavor stays the same.

Dairy-Free Option

Instead of unsalted butter, use a plant-based butter stick like Earth Balance the texture will be slightly softer but still rich and chewy.

Gluten-Free Option

Instead of all-purpose flour and regular graham crackers, use a 1:1 gluten-free flour blend and gluten-free graham crackers, such as Pamela’s the cookies will be a touch more delicate but still hold together well.

No Hershey’s Bars?

Instead of milk chocolate bars, chop up any milk or dark chocolate baking bar the sweetness level will shift slightly depending on the cocoa percentage.

Egg-Free Option

Instead of eggs, use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg) the cookies will be a bit denser but still chewy.

How to Store S’mores Cookies

Room Temperature

Store cookies in an airtight container for up to 3 days. The marshmallow topping will firm up slightly but softens again with a quick reheat.

Refrigerator

Keep in an airtight container for up to 1 week. Bring to room temperature or warm slightly before serving for the best texture.

Freezer

Freeze baked cookies in a single layer, then transfer to a freezer bag for up to 2 months. You can also freeze scooped dough balls for up to 3 months and bake straight from frozen, adding 1–2 extra minutes to the bake time.

Reheating Tip

Warm a cookie in the microwave for 10–15 seconds to restore that fresh-from-the-oven gooey marshmallow and melted chocolate texture.
