Golden pumpkin cookies with melty chocolate, toasted marshmallows, and pieces of graham cracker bake into the kind of cookie that disappears while the tray is still warm. The edges set up with a light crunch, the centers stay soft and cakey, and every bite tastes like a campfire treat without the fire pit. What makes them stand out is the balance: enough pumpkin spice to read as pumpkin, but not so much that the chocolate and marshmallow get buried.
The key is starting with blotted pumpkin puree instead of straight-from-the-can moisture. Pumpkin brings flavor and tenderness, but too much water turns cookies bready and dull. Folding in half the marshmallows inside the dough and pressing the rest on top gives you those gooey pockets inside and the toasted, sticky tops outside. A short bake time keeps the centers tender, and a quick broil at the end adds the marshmallow finish that makes these feel like s’mores instead of just spiced cookies.
Below you’ll find the little details that matter most here, including how dry the pumpkin should be, when to broil, and what to swap if you’re out of graham crackers or want a dairy-free batch.
The marshmallows on top browned up fast and the centers stayed soft instead of turning cakey. I loved getting the graham cracker bits in every bite.

The Moisture Trap That Makes Pumpkin Cookies Spread Wrong
Pumpkin puree is the ingredient that quietly changes everything in this dough. Too much moisture and the cookies bake up puffy, pale, and soft in the wrong way. Too little and you lose the pumpkin flavor that should sit under the chocolate and marshmallow instead of fighting them. Blotting the puree dry first gives you pumpkin taste without the slack dough that spreads too much or turns gummy in the middle.
The other thing people miss is that marshmallows behave better when they’re split between the dough and the tops. If they all go inside, they melt into one sticky pocket and disappear. If they all sit on top, you get a pretty finish but not much marshmallow through the cookie itself. This version gives you both.
What Each Ingredient Is Actually Doing in These Cookies
- Blotted pumpkin puree — This adds pumpkin flavor and softness, but only if you dry it first. A paper towel blot removes extra water that would otherwise make the cookies cakey and weak.
- Brown sugar — This brings moisture and a deeper caramel note that fits the graham crackers and chocolate. Granulated sugar helps the edges set and gives the cookie a little more structure.
- Graham cracker pieces — These are what make the cookies taste like s’mores instead of just spiced pumpkin cookies. Break them by hand so you get uneven bits that stay crunchy in some spots and soft in others.
- Mini marshmallows — Use half in the dough and half on top. The ones inside melt into chewy pockets, while the ones on top toast into that classic campfire finish.
- Dark chocolate chunks — Chunks hold their shape better than chips and give you those molten pools without disappearing completely. Semi-sweet works too, but dark chocolate keeps the sweetness in check.
Building the Dough So the Marshmallows Stay in Place
Start with the butter and sugars
Beat the softened butter with the brown sugar and granulated sugar until it looks fluffy and a little lighter in color. That step traps air and helps the cookies bake up with tender edges instead of dense ones. If the butter is too cold, the mixture stays clumpy; if it’s melted, the cookies spread too much and bake greasy.
Blend in the pumpkin before the flour
Add the blotted pumpkin puree, egg, and vanilla after the butter mixture is light and smooth. The dough may look a little loose at this point, and that’s fine. Once the dry ingredients go in, it comes together. If you add flour too early, the pumpkin doesn’t distribute evenly and you can end up with streaks of wetter dough.
Fold gently once the dry ingredients go in
Stir the flour, baking soda, pumpkin pie spice, cinnamon, and salt in just until no dry pockets remain. Then fold in the graham cracker pieces, chocolate chunks, and half the marshmallows by hand. Overmixing here breaks up the graham pieces and turns the marshmallows into a sticky mess before they even hit the oven.
Finish with the marshmallow tops
Scoop the dough into 2-tablespoon rounds and press the remaining marshmallows onto the tops rather than burying them. That keeps them visible enough to toast. Bake until the edges are set and the centers still look soft, then broil for about a minute if you want the tops browned and blistered. Watch them closely; marshmallows go from toasted to scorched in seconds.
Three Ways to Adjust the Batch Without Losing the S’mores Feel
Dairy-Free Version
Use a plant-based butter that behaves like stick butter, not a soft spread. The cookies still bake up tender, but the flavor will lean a little less rich, so the chocolate and pumpkin spice carry more of the work.
Gluten-Free Swap
Use a good 1:1 gluten-free flour blend and swap in gluten-free graham-style crackers. The texture will be a touch more delicate, but the cookies still hold together if you let them cool on the pan for the full 5 minutes before moving them.
Extra-Chocolate Batch
Swap half the dark chocolate chunks for chopped milk chocolate if you want a sweeter, more classic s’mores-style cookie. The result is gooier and softer, but the pumpkin spice will read a little less boldly against the sweeter chocolate.
Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days. The marshmallows soften a bit, but the cookies stay tender.
- Freezer: Freeze baked cookies for up to 2 months, or freeze scooped dough balls without the top marshmallows and add those just before baking. Marshmallows don’t freeze beautifully inside the dough, so the dough-ball method gives the best texture.
- Reheating: Warm a cookie in the microwave for 8 to 10 seconds, just until the chocolate softens. Longer heating makes the marshmallows rubbery and can dry out the cookie fast.
