These S’mores Cookie Bars combine the best of gooey s’mores and soft chocolate chip cookies in one irresistible dessert. With layers of graham cracker crust, melted chocolate, and toasted marshmallows, these bars are chewy, gooey, and perfect for sharing—or keeping all to yourself!

Ingredients

  • For the crust & cookie dough:
  • 1 cup (2 sticks, 226 g) unsalted butter, softened
  • ¾ cup brown sugar, packed
  • ½ cup granulated sugar
  • 2 large eggs
  • 2 tsp vanilla extract
  • 2 ½ cups all-purpose flour
  • 1 tsp baking soda
  • ½ tsp salt
  • 1 ½ cups semi-sweet chocolate chips
  • For the s’mores filling:
  • 68 graham crackers, broken into pieces
  • 2 cups mini marshmallows
  • 2 chocolate bars (like Hershey’s), broken into squares

Instructions

  • Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.
  • Make cookie dough: In a large bowl, cream butter and sugars until fluffy. Beat in eggs and vanilla. Stir in flour, baking soda, and salt. Fold in chocolate chips.
  • Layer base: Press half of the cookie dough evenly into the bottom of the prepared pan.
  • Add s’mores filling: Layer with graham cracker pieces, chocolate bar squares, and 1 ½ cups marshmallows.
  • Top layer: Drop spoonfuls of the remaining cookie dough over the top and gently spread (it’s okay if some marshmallows peek through).
  • Bake for 25–30 minutes, until golden brown and set.
  • Cool & slice: Let cool completely before cutting into bars for clean slices.

Notes

  • For extra gooey bars, broil for 1–2 minutes after baking to toast the marshmallows.
  • Swap chocolate bars for peanut butter cups or caramel-filled chocolate for a fun twist.
  • Best enjoyed slightly warm!
