S’mores Cookie Bars (No Campfire Needed!)

You don’t need a fire pit to enjoy a good s’more—just an oven, a pan, and this foolproof recipe. These S’mores Cookie Bars pack all the nostalgia of summer nights and sticky fingers into one golden, gooey bite: buttery graham cracker base, melty chocolate chunks, and toasted marshmallows all layered into the ultimate indoor s’mores experience.

Whether you're baking for a crowd or just want to relive your campfire days, this is your sign to make a batch—and maybe save a corner for yourself before they disappear.

🔥 S’mores Cookie Bars Recipe

Ingredients:

  • 1/2 cup unsalted butter, softened
  • 1/2 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 1 cup all-purpose flour
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1 cup graham cracker crumbs (about 8 full crackers)
  • 1 cup semi-sweet chocolate chunks (or chips)
  • 1 1/2 cups mini marshmallows

Instructions:

  1. Preheat oven to 350°F. Line an 8x8” or 9x9” pan with parchment paper.
  2. Cream butter and sugars until light and fluffy. Add egg and vanilla, mix well.
  3. Mix in flour, baking soda, salt, and graham cracker crumbs until a soft dough forms.
  4. Stir in chocolate chunks. Press 2/3 of the dough into the bottom of your pan.
  5. Layer marshmallows evenly over the dough, gently pressing them in. Crumble remaining dough over the top—leave some marshmallows peeking through.
  6. Bake for 18–22 minutes, until golden brown and marshmallows are toasty.
  7. Cool slightly before slicing—unless you want full gooey mode, then go for it.

🍫 Tips & Twists

  • Want a toasted top? Broil for the last 1–2 minutes—but watch it like a hawk.
  • Swap chocolate chunks for peanut butter chips or chopped Hershey bars for a throwback touch.
  • Add a sprinkle of flaky sea salt for that salty-sweet vibe.
