S'mores Cookies are chewy, gooey, and nostalgic, loaded with marshmallows, chocolate, and Graham crackers — and  no campfire required. Quick and easy too!


  • 1 cup unsalted buttersoftened to room temperature
  • ¾ cup light brown sugar, packed
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 and 1/2 cups all-purpose flour
  • 1 teaspoon cornstarch
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 3/4 cup chocolate chips, semisweet
  • 1 + 1/2 cups mini marshmallows, divided
  • 2 Hershey’s chocolate bars, broken up to small pieces
  • 1 and ½ cups graham crackers, broken up to small pieces (about 6-7 crackers)


  1. Preheat oven to 350F. Line a large half sheet baking tray with a silicone baking mat or parchment paper and set aside.
  2. In a large mixing bowl, use a hand mixer or stand mixer cream together butter and sugars on medium speed until light and fluffy, about 2 minutes.
  3. Add egg and vanilla, and beat on low until incorporated. Add flour, cornstarch, baking soda, and salt and beat until just combined.
  4. Add 1 cup of the graham cracker pieces, 1 cup marshmallows, and chocolate chips. Fold in until evenly incorporated in the dough.
  5. Use a medium cookie scoop to scoop out 2 tablespoons of cookie dough. Use your hands to roll it into a ball (this will ensure cookies with smooth edges). Place the cookie balls onto the lined baking sheet, spaced at least 2 inches apart (you can fit about 6-8 on a large cookie sheet).
  6. Bake for 10-12 minutes, until edges just start to brown. DO NOT OVERBAKE. The cookies may not look done in the middle, but they will continue to cook as they are cooling.
  7. Immediately press in the remaining marshmallows, graham crackers and Hershey bar pieces into the top of each cookie. Let it sit to start cooling, or optionally, pop into the broiler for about 1 minute to toast the marshmallows on top but keep a close eye on the cookies as they can burn fast.
  8. Allow the cookies to cool in the baking sheet for 5 minutes, then carefully transfer to a wire cooling rack to cool completely.


How to store: Store leftover cookies at room temperature in an airtight container for up to one week. You can extend their life by storing them in the fridge, but your cookies'taste and texture will suffer.

How to freeze: To freeze baked smores cookies, let them cool completely first, then store in an airtight container or freezer bag for up to 3 months. Allow cookies to thaw in the refrigerator overnight or on the kitchen counter until thawed.

How to reheat: Reheat on a microwave-safe plate for 5-15 seconds until warm or in the air fryer.
