s'mores cookie bars with marshmallows

Delicious S’mores Cookie Bars

Mmm. Soft, buttery, graham cracker-flavored cookie bars with smooth chocolate and gooey marshmallow layered throughout. I highly recommend you try this s’mores cookie bars recipe!

Just as with the s’mores cookie cups, I think these s’mores cookie bars are even better than your average s’more. Plus, with this recipe, there’s no fire needed, and these bars are easy to make and serve to large groups or give to friends. Gotta love cookie bars!

The easiest way to make graham cracker crumbs:

making graham cracker crumbs for smores cookie bars

Just throw some graham crackers in a food processor or blender for quick and easy graham cracker crumbs. I believe it usually takes 7 to 8 whole graham crackers for 1 cup of crumbs.

Can I use regular marshmallows?

Do not substitute marshmallows for the marshmallow creme! The marshmallows will basically melt and disappear in the oven, while the creme stays perfectly soft and gooey.

Don’t worry, if you’re not familiar with marshmallow creme, you can easily find it right by the marshmallows. These cookie bars are totally worth it! Trust me.

How to prepare your s’more cookie bars for the oven:

Press half of the cookie dough into the bottom of a foil-lined 9×13 pan, then layer on the marshmallow creme and then the chocolate chips. I decided to use milk chocolate chips to stay true to traditional s’mores flavor, but you can use whatever kind you like. (Guittard milk chocolate chips are my fav!)

Top it all off with the rest of the cookie dough in clumps. Bake it up and enjoy! Such an easy and delicious treat!

Easy S’mores Cookie Bars Recipe

5 / 5 (3 reviews)
Prep Time: 15 mins | Cook Time: 30 mins
Yield: 9x13 | Serves: 24


  • 2 cups all-purpose flour
  • 2 cups graham cracker crumbs
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 16 tablespoons (2 sticks) butter, room temperature
  • 1 1/2 cups packed light brown sugar
  • 1 teaspoon vanilla
  • 2 large eggs
  • 2 cups marshmallow topping, Marshmallow Fluff or Creme (7 ounce container)
  • 2 cups milk or semisweet chocolate chips


  1. Preheat the oven to 350. Line a 9X13-inch pan with foil, leaving a 2-inch overhang on the 2 short sides. Grease the foil with cooking spray and set aside.

  2. In a medium bowl, whisk together the flour, graham cracker crumbs, baking powder and salt.

  3. In a large bowl, using an electric mixer on medium speed, beat the butter and sugar until light, about 2 minutes. Beat in the eggs and vanilla until well combined. Reduce the mixer speed to low and add the flour mixture, mixing just until combined.

  4. Divide the dough in half. Press half into the bottom of the prepared pan until the dough is evenly flattened.

  5. Dollop the marshmallow topping on top of the cookie base and gently spread into an even layer. Sprinkle the chocolate chips on top.

  6. Scatter the remaining dough over the top in clumps. Don’t worry about completely covering the top.

  7. Bake the bars until golden brown, about 30-32 minutes. Cool completely. Remove from the pan with the foil, cut into bars, and serve.
