Ingredients

Main Ingredients

  • 1 cup Unsalted Butter, softened
  • 1 cup Granulated Sugar
  • 1 cup Brown Sugar, packed
  • 2 Large Eggs
  • 1 tablespoon Vanilla Extract
  • 3 cups All-Purpose Flour
  • 1 teaspoon Baking Soda
  • 1/2 teaspoon Salt
  • 1 cup Semi-Sweet Chocolate Chips
  • 1 cup Mini Marshmallows
  • 1 cup Graham Cracker Crumbs
  • 1/2 cup Mini Chocolate Chips, for topping

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish or line it with parchment paper to ensure easy removal of the bars after baking.
  2. Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy, creating a smooth base for the dough.
  3. Add Eggs and Vanilla: Add the eggs one at a time to the creamed mixture, mixing well after each addition. Then stir in the vanilla extract to enhance the flavor.
  4. Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt to evenly distribute the leavening agents and seasoning.
  5. Combine Dry and Wet Ingredients: Gradually add the dry mixture to the wet ingredients, stirring gently until just combined to avoid overmixing, which can toughen the bars.
  6. Fold in S'mores Elements: Carefully fold in the semi-sweet chocolate chips, mini marshmallows, and graham cracker crumbs, ensuring they are evenly distributed throughout the dough.
  7. Prepare the Baking Dish: Pour the cookie dough into the prepared baking dish, spreading it evenly, and press down gently to compact the dough for a uniform bake.
  8. Add Topping: Sprinkle the mini chocolate chips evenly over the top of the batter for an extra layer of chocolate goodness.
  9. Bake: Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs, indicating they are baked through but still soft inside.
  10. Cool and Serve: Allow the bars to cool in the baking dish for at least 10 minutes. Then, using the parchment paper, lift the bars out and transfer them to a wire rack to cool completely before cutting into squares and serving.

Notes

  • For an extra touch, try adding some crushed graham crackers sprinkled on top before baking for added crunch.
  • Drizzle with melted chocolate once cooled for an even richer flavor and decorative finish.
  • Store bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
