These smores cookie bars combine chewy chocolate chip cookie dough with gooey marshmallows, milk chocolate, and graham crackers for a classic campfire-inspired treat. They are easy to make in a baking pan and perfect for sharing.
Preheat the oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper or lightly coat it with cooking spray.
In a medium bowl, whisk together the flour, baking soda, and salt.
In a large bowl, beat the softened butter, brown sugar, and granulated sugar until light and creamy.
Add the eggs one at a time, beating well after each addition, then mix in the vanilla extract.
Gradually add the dry ingredients to the wet ingredients and mix just until combined.
Fold in the semi-sweet chocolate chips and 1 cup of the graham cracker pieces.
Press about two-thirds of the cookie dough evenly into the prepared pan.
Sprinkle the milk chocolate chunks, mini marshmallows, and remaining graham cracker pieces evenly over the dough.
Drop the remaining cookie dough in small pieces over the top, then gently press it down so some marshmallows and chocolate remain visible.
Bake for 22 to 28 minutes, or until the top is golden brown and the center is set but still slightly soft.
Allow the bars to cool completely in the pan before lifting them out and cutting into squares.
Notes
For cleaner slices, let the bars cool completely before cutting. If you prefer extra gooey bars, slightly underbake them and allow them to finish setting as they cool.
