Maybe it’s the lightly sweetened graham crumb crust, maybe it’s the chocolatey filling, but these absolutely melted in our mouths!

This S’mores Bar recipe is a bit different because instead of using just chocolate bars and marshmallows for the filling, it includes a quick and easy, but really delicious cookie dough filling. 

Of course, the traditional s’more ingredients are included to make sure you bite into all the flavors of your childhood! Who doesn’t have amazing memories of making s’mores around a campfire?

What Are S’mores Bars?

S’mores bars are cookies that include the traditional ingredients of s’mores, the campfire treat made from graham crackers, chocolate bars, and marshmallows. Instead of roasting marshmallows over a fire and assembling your s’mores outside, s’mores bars are made in the kitchen!

How Do I Store S’mores Bars?

S’mores bars keep really well at room temperature. Store them in an airtight container for 4-5 days. You can also keep them in the fridge, but they’ll become much chewier since the chocolate and marshmallow will harden.

Can I Freeze S’mores Bars?

Yes, you can freeze s’mores bars for up to 3 months. Make sure you wrap them well so the marshmallows don’t get freezer burnt. You’ll want to allow them to thaw to room temperature for about 6 hours before you enjoy them.

Why Are They Called ‘S’mores’?

S’mores (or smores) is a contraction of the words ‘some more.’ While no one is absolutely sure when they were invented, it’s possible Girl and Boy Scouts were making them over 100 years ago! Wherever they came from, we can all agree, there’s always room for some more s’mores!

Tips for Making Recipe Name

  • This recipe can be doubled if you need to make a lot. You’ll want to bake the pans separately though, or make sure you rotate them during baking.
  • This recipe calls for Hershey bars, but you can use other types of chocolate bars. We especially love Jersey Milk bars!
  • Don’t overbake these! You will want to take them out of the oven when the marshmallows begin to turn brown. If you bake them too long, they’ll become hard instead of gooey.

S’mores Bars Recipe

All the goodness of campfire S’mores, but made in the kitchen, these ooey-gooey cookie bars are made with marshmallows, chocolate, and a graham crumb crust. The yummy cookie dough filling layer will make these an irresistible treat your whole family will die for.

  • Add the butter to your graham crumbs slowly. You may need more or less depending on your graham crumbs. You want them to be wet and to stick together slightly, but you don’t want your butter to be pooling.
  • Don’t over-mix your cookie mixture. Once it’s incorporated and there are no more streaks of flour, you’ve mixed enough. Over-mixing will lead to a stiffer dough and your bars won’t be as chewy.
  • To make your graham crumbs, you can place your crackers in a food processor and mix until they are crumbled, or you can place them in a Ziploc bag and roll with a rolling pin.


  • Graham Crackers – Some grocery stores may carry pre-made graham cracker crumbs. Simply measure out the crumbs in equal amounts and you won’t have to crumble your own.
  • Brown Sugar – If you’re out of brown sugar, you can use granulated sugar and molasses to make your own. To make 1 cup of light brown sugar, add 1 tbsp of molasses to 1 cup of granulated sugar and stir well with a fork.
  • Chocolate Bars – You can add all kinds of fun toppings to your S’mores Bars. Sprinkle M&Ms, different types of chocolate bars, and even berries on top! Just watch them carefully to make sure nothing burns.

S'mores Bars Recipe

S'mores Bars Recipe
Prep Time 15 minutes
Cook Time 35 minutes
Total Time 50 minutes



  • 2-1/4 cups graham crackers (1-1/2 sleeves, crushed)
  • 2/3 cup unsalted butter, melted
  • 1/3 cup granulated sugar

Cookie Layer

  • 1 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 3/4 cup packed brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla
  • 2 1/4 cup all-purpose flour
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 3 cups miniature marshmallows, divided
  • 1 cup semi sweet chocolate chips, divided
  • 2 large Hershey bars, broken into squares


  1. Preheat the oven to 350 degrees F. Line a 9x13 pan with parchment paper and spray with nonstick spray.
  2. Mix together the crushed graham crackers, butter and sugar until thoroughly covered in butter. Spread the crumbs into the base of the pan. Use the base of a cup or measuring cup to press the cracker mixture firmly into an even layer. Packing it down well makes sure the bars don’t crumble.
  3. Bake for 7 minutes, and then remove from the oven to cool a bit.
  4. In a large bowl, cream together the butter and sugars. Then, add in the eggs and vanilla and mix well. Add the flour in two additions, making sure to stir the mixture in between each addition. Sprinkle the salt and baking soda on top of the first addition of flour so that it can get mixed in. Combine the mixture until the flour is just incorporated.
  5. Add ¾ of the marshmallows and 3/4 of the chocolate chips to the cookie dough mixture and mix until well disbursed
  6. Carefully spread the cookie dough on top of the crust and bake for 18 minutes.
  7. After removing the bars from the oven, scatter remaining marshmallows, chocolate chips, and place the chocolate squares on top of the bars and bake for an additional 9-11 minutes, or until it is golden brown on top. You want soft and gooey bars so be sure not to over bake them!


You'll need a 9" x 13" pan
