What’s Up, Hungry People!

I have a confession: I live and breathe for those ooey-gooey s’mores moments. You know, the kind where the chocolate and marshmallow become one, and it’s pure bliss? While there’s something iconic about roasting marshmallows over a blazing campfire, I’ve found that baking s’mores indoors brings its own kind of magic. With these s’more cookie bars, you’re in for a treat bursting with marshmallow and chocolate goodness.

One of the game-changers for ultra-soft and chewy s’more bars? Homemade marshmallow cream. It truly does wonders. However, if you’re in a hurry or don’t have the ingredients on hand, the store-bought version will work just fine.

Pro tip: To get those perfect slices, it’s a good idea to let the bars set until they’ve reached room temperature before cutting. But, between you and me, if you can actually wait that long without sneaking a bite… kudos to you. We all know I’m diving in while they’re still warm!

Here’s What You Need:

  • Sugar: Sweetens and adds texture to the dough.
  • Brown Sugar: Imparts a molasses flavor and moisture to the bars.
  • Butter: Provides fat, flavor, and moisture for a soft texture.
  • Egg: Binds ingredients together and adds moisture.
  • Vanilla Extract: Enhances overall flavor, giving a subtle aromatic touch.
  • Crushed Graham Crackers: Adds a distinct s’mores flavor and texture.
  • Flour: The main structure-builder in the dough.
  • Baking Soda: Acts as a leavening agent, making the bars rise.
  • Marshmallows: Adds the gooey texture and sweetness characteristic of s’mores.
  • Light Corn Syrup: Ensures a smooth, even texture for the marshmallow cream.
  • Hershey Chocolate Bars: Melts to provide the classic s’mores chocolate layer.
  • Whole Graham Crackers: Creates layers and adds crunch to the bars.

  • Dough Consistency: If your dough feels too dry, add a tablespoon of milk or water until it reaches the desired consistency. Remember, the environment, such as humidity, can affect the dough.
  • Double Boiler Technique: When melting marshmallows, using a double boiler prevents them from burning. Always ensure the water doesn’t touch the bottom of the top bowl.
  • Choosing Chocolate: While Hershey’s is classic for s’mores, feel free to experiment with other chocolates like dark or white for a twist.
  • Cutting Bars: For cleaner cuts, use a sharp knife dipped in warm water. This helps slice through the gooey marshmallow layer with ease.
  • Storage: Store in an airtight container to maintain freshness. If they become a bit hard over time, warming them up in a microwave for a few seconds can help soften them.

S’mores have always been a treat that evokes memories of campfires and starry nights, but who says you can only enjoy them outdoors? With the s’mores cookie bars, you get all the flavors you adore, wrapped up in one delightful indoor bake. The ooey-gooey chocolate, the melty marshmallows, and that familiar graham cracker crunch – it’s all there. And the best part? No campfire required. Every bite takes me back, and I hope it does the same for you. Let’s keep the s’mores spirit alive, Hungry People!

  • Preheat the oven to 350°F. In a mixing bowl, combine white sugar, brown sugar, butter, egg, and vanilla extract. Mix until smooth. Then, fold in the crushed graham cracker crumbs.
  • Gradually add the flour and baking soda to the mixture, stirring until a thick dough forms. Once combined, set the dough aside.
  • Prepare a double boiler by filling a pot with water and bringing it to a boil. Place a metal bowl over the boiling water. Add the marshmallows to the bowl, stirring with a wooden spoon until they become sticky. Add the corn syrup and continue stirring until the mixture is smooth, about fifteen minutes.
  • Grease a 9×9-inch baking pan. Divide the previously prepared dough in half. Spread one half of the dough evenly at the bottom of the pan.
  • Layer 4-5 whole graham crackers over the dough. Place the chocolate bars on top of the graham crackers.
  • Pour the smooth marshmallow cream over the chocolate bars. Layer with the remaining whole graham crackers.
  • Take the remaining half of the dough, tear it into pieces, and scatter them over the exposed marshmallows. (Note: As the bars bake, the dough will spread to cover any gaps.)
  • Bake in the preheated oven for 15-20 minutes, or until the top turns a golden brown.
  • After baking, remove the pan from the oven. Allow the s'mores bars to set for at least an hour before cutting into them. If you're feeling adventurous, you can also dig in right away for an ooey-gooey mess. Enjoy!
