S’mores Bars


Summer may be nearly over but with these delicious s’mores bars you can have a taste of summer all year long! I know in the middle of the winter I’m totally going to be making these decadent bars. They taste just like a s’more but in more of a soft and chewy cookie bar form. They are over the top and melt in your mouth delicious! I’m thinking I’m going to have to start replacing some of the flour in this Chocolate Chip Cookie S’more recipe with fine graham crackers crumbs so I can get the same taste these have.

S’mores Bars

These decadent S'mores bars will leave everyone craving more! You get a buttery graham cracker cookie base that sandwiched with rich chocolate and creamy marshmallow cream.

Servings: 12 Bars
Prep Time 25 minutes
Cook Time 30 minutes


  • 1 1/4 cups all-purpose flour
  • 3/4 cup fine graham cracker crumbs
  • 1/4 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup unsalted butter, softened
  • 1/2 cup packed light-brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 2 (4.4 oz) XL Hershey milk chocolate bars
  • 1 (7 oz) jar marshmallow creme


  1. Preheat oven to 350 degrees. Butter and 8 by 8-inch baking dish and line with two sheets of parchment paper, leaving a slight over hang on each side, and butter paper (if you don't care to lift the bars out in one, for easier cutting, you can just butter the baking dish without lining).
  2. In a mixing bowl whisk together flour, graham crack crumbs, baking soda and salt for 20 seconds, set aside.
  3. In the bowl of an electric stand mixer fitted with the paddle attachment, blend together butter, brown sugar and granulated sugar until creamy. Mix in egg and vanilla extract. With mixer set on low speed, slowly add in dry ingredients and mix until combined.
  4. Divide dough in half and press one half of the dough into an even layer in the bottom of prepared baking dish*. Place chocolate side by side over dough layer. Top chocolate with marshmallow fluff, spreading into an even layer.
  5. Take about golf ball size pieces of remaining dough and flatten into small shingles and layer side by side over marshmallow fluff (work to keep any of the fluff from showing through).
  6. Bake in preheated oven 27 - 30 minutes until top is lightly golden brown. Cool completely on a wire rack before cutting into squares (use parchment overhang to lift bars from pan before cutting. I recommend cutting just before serving as the filling will being to run a little). Store in an airtight container.
  7. Here is a great tip from reader Jane A. that I want to try next time (doing this vs. shaping little squares and pressing together for the top): press in half the dough, then take it out/peel off the parchment and save this slab to put on top of the marshmallows.
  8. Press in the other half of dough into the pan and proceed with recipe. Thanks Jane!

  • Jenn: I’ve made these several times over the years and they are always a hit! Sometimes it can be a challenge to find the correct size Hershey bars but I always manage. Sooooooo good. October 20, 2018 at 6:02pm Reply

  • KE: This is an awesome recipe for smore bars. Family and all others that tried it have liked it. My pan curved at the bottom so the chocolate bars didn’t fit as the recipe described, so I chopped the extra chocolate and used it to garnish the top after it came out of the oven.

  • Lisa: Another winner from you, Jaclyn! School started yesterday here in Texas although it will be hotter than hell for months yet. Two of my grandchildren are in school & I have something special for them each day when they get home. These were in the rotation for yesterday and so delicious. Thank you so much for all of your recipes that my family enjoys. August 21, 2018 at 10:13am Reply

  • Angi: We went on a hunt for a s’mores bar, and this recipe made the cut. Unfortunately, after all was said and done, this was just too rich for my family!

    I’m glad other folks like it, but it’s difficult to get through even a small piece. It’s just too much! My favorite part of it was the roasty toasty edges of the marshmallow that escaped, but that’s it. :-(

    Not hard feelings – just my review! July 25, 2018 at 11:11am Reply
