Tomorrow is the first day of Summer, so what better way to start summer with cookies most associated with a summer treat around the campfire: S’mores!
Unfortunately, these are cookies that require some pre-planning as they require the dough to sit for a minimum of 1 hour before you bake them.
The recipe reads like a typical chocolate chip cookie with the addition of graham crackers, Hershey’s chocolate, and mini marshmallows. They’re easy to make, and aren’t exactly the prettiest looking cookie out there. They’re definitely not going to win any contests based on presentation, but they’ll win by taste.
I rearranged the ingredients list so they’re in order of when you need them according to the instructions, which should clarify things.

Ingredients:
- 1 cup mini marshmallows OR marshmallow bits, divided
- 1 bar Hershey’s Chocolate 1.55oz
- 4 Graham crackers 56g
- 1 1/2 cups all-purpose flour 180g
- ¼ tsp salt
- ½ tsp. baking powder
- ½ tsp. baking soda
- 1 tsp corn starch
- 10 tbsp unsalted butter room temperature (1 1/4 stick of butter)
- 1/4 cup granulated sugar
- 1/2 cup light brown sugar
- 1 egg
- 1 tsp vanilla extract
- 3/4 cup semisweet chocolate chips
Instructions:
- Roughly chop the Graham crackers and Hershey’s bar, then tear the mini marshmallows in half. These marshmallows are one of the best parts of the cookie but they will puff up and get a bit out of control if you don’t halve them.
- Combine the flour, salt, baking powder, baking soda, and cornstarch in a bowl then whisk together and set aside.
- Using a stand or hand mixer, beat butter and sugars in a bowl until creamy, about 2 minutes. Add in egg and vanilla and until combined. Scrape the bowl down and mix once more.
- Gradually add flour mixture to butter mixture, beating on low speed until just combined.
- Reserve a handful of the torn marshmallows and set aside then add the remaining marshmallows, chocolate chips, and Graham crackers to the dough and mix on low until just combined (do not over-beat).
- Refrigerate dough for an hour or more.
- Heat oven to 350F. Portion out roughly two tablespoon sized pieces of dough. Roll into balls and place on a parchment-lined baking sheet, spacing about 2 inches apart.
- Bake at 350° for 8 minutes then top the cookies with the reserved marshmallow and Hershey’s bar pieces then return to the oven for 2-3 minutes to finish baking. If some cookies had a blowout because of a few too many marshmallows to you can corral them back together with a round cookie cutter or a knife.
- Leave on pan to cool completely.
