ingredient notes & substitutions
Chocolate chips: You will need both chocolate chips and chocolate bars for these s'mores cookies. I prefer Ghiradelli 72% Dark Chocolate but you can also use Hershey bars for a more classic s'more pairing.
Marshmallows: This recipe uses large marshmallows, not mini ones. In testing, I found the big marshmallow yields the best gooey centers. Jet-Puffed marshmallows melt best!
Graham crackers: You can use any flavor of graham cracker, I used classic honey graham crackers.

Step #2 - Mix in the wet ingredients. Mix in the egg, egg yolk, and vanilla extract until just combined. Scrape down the sides of the bowl.
Step #3 - Mix in the dry ingredients. Mix in the dry ingredients and mini chocolate chips until just combined.
Cover the bowl with plastic wrap and chill the dough in the fridge for 1 hour.
Step #4 - Stuff with marshmallows. Scoop a ball of cookie dough into your palm.
Then place one large marshmallow long side down into the center.
Mold and shape the dough around the marshmallow, leaving just a bit poking through on top.
Step #5 - Chill and bake! Press a few pieces of graham crackers pieces and crumbs on top of each cookie.
Then chill them in the fridge for another 1-2 hours.
When ready to bake, place the cookies spaced 2-3 inches apart on a lined tray and bake for 10-11 minutes.
Step #6 - Top with chunks of chocolate. As soon as the cookies are done baking, use a round cookie cutter to scoot the edges in to make them perfectly round. Then top each cookie with chocolate chunks.
Allow the pan to cool on a wire cooling rack before removing them. Enjoy your chocolate s'mores cookies!
expert baking tips
- Use a kitchen scale. Baking with a scale is much more accurate than cup measurements. To convert this recipe, click the "metric" button next to the ingredients title on the recipe card. If you do not have a scale, use a spoon to fluff the flour first, then spoon it into your measuring cup.
- Chill the dough. This step is important because the dough needs to be cold before stuffing them, otherwise, it will be a sticky mess. It also keeps the cookies from spreading too much in the oven.
- Keep a damp towel nearby. While stuffing the cookie dough with marshmallows, you may notice that it tends to stick to your hands. To prevent this, have a moist paper towel within reach to wipe your hands and prevent them from sticking to you.
I found while developing this recipe that large marshmallows do best. The mini marshmallows tend to melt quickly and disappear into the dough.
Store any leftover cookies in an airtight container at room temperature for 2-3 days.
If you need to freeze them for later, let the cookies defrost in the fridge overnight then bake them the next day. If you bake them straight from the freezer, the marshmallow gets too brown and melty and disappears into the cookie.
