Ingredients

Scale

Cookie Base

  • 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

Topping

  • Extra chocolate chips, to taste
  • Extra mini marshmallows, to taste

Instructions

  1. Prepare the pan: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan or line it with parchment paper for easy removal.
  2. Cream butter and sugars: In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
  3. Add eggs and vanilla: Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract until fully incorporated.
  4. Mix dry ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
  5. Combine mixtures: Gradually add the dry ingredient mixture to the butter and sugar mixture, mixing just until combined to avoid overmixing.
  6. Add graham crackers and chocolate chips: Gently fold in the graham cracker crumbs and chocolate chips until evenly distributed throughout the dough.
  7. Layer dough and marshmallows: Spread half of the cookie dough evenly into the prepared baking pan, pressing it down gently. Sprinkle mini marshmallows over this layer, then cover with the remaining cookie dough, spreading gently to cover the marshmallows.
  8. Add toppings: Sprinkle extra chocolate chips and mini marshmallows on top for added gooeyness and texture.
  9. Bake: Place the pan in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
  10. Cool and serve: Let the bars cool in the pan for about 10 minutes. Then use the parchment paper to lift them out and transfer to a wire rack to cool completely before slicing into squares.
  11. Enjoy: Serve and enjoy these delicious S’mores Cookie Bars with family and friends!

Notes

  • Ensure the butter is softened for better creaming with sugars.
  • Do not overmix the dough to keep the bars tender.
  • Use parchment paper for easy removal from the pan.
  • Feel free to adjust the amount of marshmallows and chocolate chips for desired gooeyness.
  • Store bars in an airtight container at room temperature for up to 3 days.
  • Can be frozen for up to 1 month; thaw before serving.
