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 for easy removal of the cookie bars.
  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, which ensures a tender texture.
  3. Add Eggs and Vanilla: Add the eggs one at a time to the creamed mixture, mixing well after each addition to incorporate fully. Stir in the vanilla extract for flavor.
  4. Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt to evenly distribute the leavening and seasoning.
  5. Combine Wet and Dry: Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Avoid overmixing to keep the bars tender.
  6. Fold in Mix-ins: Fold in the semi-sweet chocolate chips, mini marshmallows, and graham cracker crumbs until evenly distributed throughout the dough.
  7. Spread Dough: Pour the cookie dough into the prepared baking dish and spread it out evenly. Press down gently to make the dough compact and uniform.
  8. Add Topping: Sprinkle the mini chocolate chips on top of the batter to add extra chocolate flavor and texture.
  9. Bake: Bake in the preheated oven for 25 to 30 minutes or until the edges turn golden brown and a toothpick inserted in the center comes out with a few moist crumbs, indicating perfect doneness.
  10. Cool and Cut: Allow the cookie bars to cool for at least 10 minutes in the baking dish. Then, use the parchment paper to lift the bars out gently and transfer them to a wire rack to cool completely before cutting into squares for serving.

Notes

  • For an extra touch, sprinkle some crushed graham crackers on top before baking to enhance the texture.
  • Try drizzling melted chocolate over the cooled bars for added decadence.
  • Store any leftovers in an airtight container to keep them chewy and fresh.
