Ingredients and Necessary Utensils

Ingredients

  • 1 cup unsalted butter, softened
  • 1 cup brown sugar, packed
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup graham cracker crumbs
  • 1 cup chocolate chips
  • 1 cup mini marshmallows
  • Extra chocolate chips and marshmallows for topping

Necessary Utensils

  • 9×13 inch baking pan
  • Mixing bowls
  • Electric mixer (or whisk)
  • Rubber spatula
  • Whisk
  • Parchment paper (optional, for easy removal)

Detailed Recipe Steps

  1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking pan or line it with parchment paper for easy removal.
  2. Mix Butter and Sugars: In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy. This step is crucial as it incorporates air into the batter, making the bars tender.
  3. Add Eggs and Vanilla: Beat in the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract for added flavor.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt. This ensures that the leavening agent is evenly distributed throughout the flour.
  5. Mix Dry and Wet Ingredients: Gradually add the dry mixture to the butter mixture, stirring until just combined. Be careful not to overmix, as this can lead to tough bars.
  6. Fold in Graham Cracker Crumbs and Chocolate Chips: Gently fold in the graham cracker crumbs and chocolate chips using a rubber spatula until evenly distributed throughout the dough.
  7. Spread in Pan: Spread half of the cookie dough mixture into the prepared baking pan, pressing it down evenly to form the base layer.
  8. Add Marshmallows: Sprinkle the mini marshmallows over the first cookie layer, then add the remaining cookie dough on top, spreading it gently to cover the marshmallows.
  9. Add Toppings: Top with additional chocolate chips and mini marshmallows for an extra gooeyness that will have everyone drooling!
  10. Bake: Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
  11. Cool and Slice: Allow the bars to cool in the pan for about 10 minutes. If you used parchment paper, lift them out and let them cool completely on a wire rack before slicing into squares.
  12. Serve: Enjoy your delicious S’mores Cookie Bars with family and friends. They are perfect for sharing or indulging in all by yourself!
