August has a particular kind of magic to it, long, golden days that feel like they might never end. And then, almost without warning, the smell of new pencils and the sound of the school bus returns. These S’mores Cookies were born from that feeling: the desire to hold onto summer just a little longer. Every bite brings back campfire memories, melted chocolate, sticky marshmallow, the satisfying crunch of a graham cracker under a starry sky. Make a batch together before the first day of school- a sweet, gooey send-off from the endless days of summer.

S'mores Cookies
Every bite of these S'mores cookies brings back summer campfire memories, melted chocolate, sticky marshmallow, the satisfying crunch of a graham cracker under a starry sky.
- Total Time: 0 hours
- Yield: 20, 2.5 ounce cookies
Ingredients
- ½ bag of mini marshmallows (about 2 cups)
- 2 sticks (1 cup) butter, cubed and kept cold
- 150g granulated sugar
- 165g dark brown sugar
- 2 eggs plus 1 egg yolk
- ½ teaspoon vanilla extract
- 140g unbleached all-purpose flour
- 150g bread flour
- 1 teaspoon baking soda
- 40g cornstarch
- ½ teaspoon salt
- ½ teaspoon espresso powder
- 5 oz semi-sweet chocolate chips
- 5 oz milk chocolate chips, plus more for topping
- 1 cup of crushed graham crackers
- 20-24 graham cracker squares
- Hershey milk chocolate bars
- Sea salt
Instructions
Dehydrated Marshmallows
- Preheat your oven to its lowest temperature (mine is 170 degrees).
- On a baking tray lined with parchment paper, spread out a half a bag of mini marshmallows.
- Bake marshmallows for 2 to 2 ½ hours to dehydrate.
- As they cool, they will become hard. Let them cool completely and store in a container.
Cookies
- Cube butter and refrigerate until ready to use.
- Weigh and mix both sugars together in a bowl.
- In a separate bowl, whisk together both flours, baking soda, cornstarch, salt, and espresso powder.
- In a stand mixer, cream cold butter briefly. Add sugars and mix for 2-3 minutes until incorporated and beginning to look fluffy.
- Add eggs one at a time, fully incorporating each before adding the next. Add vanilla extract.
- Add dry ingredients in small batches, mixing just until incorporated. Do not over mix.
- By hand, fold in chocolate chips.
- Scrape dough into an airtight container and refrigerate overnight.
- When ready to bake, preheat oven to 350°F.
- Scoop 2.5 oz portions of dough. Break apart the portion and add 3-4 dehydrated marshmallows to the center. Press together and form into tall ball. Press a few more marshmallows into the top of the cookie.
- Mix extra chocolate chips and graham crackers crumbs for topping. Press the top of each ball into the chip and graham cracker mixture. Place the ball of dough onto a graham cracker. Sprinkle with sea salt.
- Bake 12-14 minutes, watching from the 12-minute mark. Edges should look set but centers will look slightly underdone.
- Remove from oven. Leave on the pan for 10-15 minutes before transferring to a cooling rack. While the cookie is slightly warm, break off a piece of Hershey bar and press into the top of each cookie.
Notes
- Make dehydrated marshmallows a few days in advance. They will last for some time. They can be used in hot chocolate too.
- Trader Joes has graham crackers that are square. If you cannot find there, rectangle graham crackers will work well too.
- Unbaked dough keeps in the refrigerator for up to one week. Baked cookies keep at room temperature for 3-4 days.

Language Corner
These language guides are here to support you, not overwhelm you! Pick one word, one prompt, or one concept that feels right for your child and your moment. There is no right or wrong way to use them. The best conversation is the one that happens naturally while you are cooking together.
✦ Word of the Day:
Dehydrate (say it: “de-HY-drate”) means to remove water from something. The word comes from the Greek “hydor,” meaning water, with the prefix “de-” meaning to take away. In this recipe, we place marshmallows in a very low oven for a couple of hours to slowly dry them out. Once the water is gone, they become firm instead of soft, which means they hold their shape inside the cookie and give you little pockets of chewy, toasted marshmallow in every bite instead of disappearing into the dough.
Try it: Say “dehydrate” out loud. Can you hear the three syllables: “de”-“hy”-“drate”? Now use it in a sentence: “We dehydrated the marshmallows so they would stay chewy inside the cookie.” Can you think of other foods that get dehydrated? (Raisins, beef jerky, dried mangoes)
✦ Describing Words
The kitchen is one of the best places to practice describing words. As you bake, pay attention to what you notice: the dough is soft and cool, the graham crackers are crispy and sweet-smelling, the chocolate chips are smooth and shiny. Once the cookies come out of the oven, everything changes, the marshmallows are puffed and golden, the chocolate is warm and glossy, and the whole cookie is gooey, melted, and just a little bit sticky.
Try it: Pick one ingredient from the counter and describe it using three words: one for how it looks, one for how it feels, and one for how it smells or tastes. For example: “The marshmallows are white, squishy, and sweet.” Now try the same thing after the marshmallows come out of the oven, have the words changed?
✦ Figure of Speech: Fold In
When step 7 says to “fold in” the chocolate chips, it is borrowing a word we usually use with laundry or paper. To fold means to gently turn one part over another, like folding a letter or tucking in a blanket. In baking, “fold in” means to mix something delicate into the batter using slow, gentle strokes so you do not overwork the dough. If you stir too hard or too fast, the cookies can come out tough instead of tender. So folding is about treating the dough gently, so it stays soft.
Try it: Can you think of another time we use the word “fold”? (Folding clothes, folding a piece of paper into an airplane, folding your hands.) What do all of those have in common? Now try folding the chocolate chips in yourself, see if you can do it slowly and gently without stirring.
✦ Talk While You Cook
While crushing the graham crackers: “How many ways can you think of to break something into small pieces? What happens to the crackers when we crush them? Do they look the same? Feel the same? What do you think the crumbs do for the cookie?”
While scooping and shaping the dough: “We are putting marshmallows inside the dough, so they are hidden. What do you think will happen to them in the oven? Can you predict what the inside of the cookie will look like when we break one open?”
While waiting for the cookies to cool: “If you could bring these cookies anywhere, where would you bring them? What is your favorite summer memory? If this cookie could have a name for this summer, what would you call it?”
There are no wrong answers, just good conversation!
✦ Think Like a Chef
A chef is always asking “what if?” and this recipe is a perfect place to start. What if you swapped the milk chocolate chips for dark chocolate? The flavor would be deeper and a little more bitter, which some people love with the sweetness of the marshmallow. What if you tried peanut butter chips instead of one of the chocolate varieties? The combinations are nearly endless, and the only way to find out is to try.
Try it: “If you could change one thing about this recipe, one ingredient, one step, or one topping, what would it be and why? What do you think would happen if we made that change? Would the cookies taste better, different, or maybe not as good?”
✦ A Note on Kitchen Safety
There is so much for little hands to do in this recipe. Kids can measure and mix the dry ingredients, crush the graham crackers (especially fun in a zip-lock bag with a rolling pin), help weigh ingredients, fold in the chocolate chips, and press marshmallows and chocolate chips into the tops of the cookies once they have cooled enough to touch. Scooping the dough is also a great job for older children.
For Parents: The oven belongs to the grown-ups, dehydrating the marshmallows happens at a very low temperature over several hours, and baking the cookies requires moving hot pans in and out of a 350° oven. The cookies and the pan stay hot for longer than you might expect after they come out. Wait a full 10–15 minutes before pressing the Hershey bar pieces in and remind little ones that even when something looks cool, it can still be warm underneath. Always use oven mitts and set the pan on a heatproof surface.
