S’mores Cookie Bars

It’s the perfect weather for making s’mores in New England as summer draws to an end, and if you’re looking to have that combination of flavors on-the-go or take to a party where you won’t have a fire available to make them, then this is the perfect recipe.

Combining the same ingredients and more, these cookie bars quite a flavor. However, these are also quite heavy, and the next time, I’d spread this same amount of crust listed below on a larger 13 x 9 pan (I used a 9 x 9 pan for these), because I think I’d prefer a thinner cookie bar. I made this batch to take to a movie at a friend’s place, but it would also be a great dessert to carry to a picnic.

Recipe from Joan Hayes over at Chocolate, Chocolate and More


  • 3/4 cup graham cracker crumbs
  • 4 tablespoons butter, melted
  • 3/4 cup sugar
  • 1/2 cup brown sugar
  • 1/2 cup butter, softened
  • 1 egg
  • 1/2 teaspoon vanilla
  • 1 1/4 cup all purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup chocolate chips
  • 1/2 cup mini marshmallows plus a few extra for the top
  • 1 regular sized milk chocolate Hershey Bar


  1. Line a square baking pan with parchment paper (I used a 9 x 9 pan, but I recommend a 9 x 13 pan in order to make a thinner cookie bar). Combine graham cracker crumbs and melted butter. Place in bottom of prepared pan and press down to form a crust.
  2. Cream 1/2 cup softened butter, add in sugars and cream again till fluffy. Add in egg and vanilla. Mix again. Combine Flour, baking soda and salt, then add to butter mixture. Once all combined, fold in chocolate chips and marshmallows. Spoon Cookie dough on top of cookie crust as evenly as possible. Don’t worry about spreading perfectly. Dough will spread as it cooks to fill in any gaps. Bake in a preheated 350 degree oven for about 20 minutes.
  3. While bars are cooking, break candy bar into sections and place in freezer. 8-10 minutes before bar is done cooking, sprinkle remaining marshmallows on top, just to decorate. Return to baking for remaining time. Remove pan from oven and carefully place broken candy bar pieces on top. Let cool completely before cutting.
