You can add a few optional items for extra flavor: - A sprinkle of sea salt on top - Chopped nuts like walnuts or pecans - Swirls of peanut butter or Nutella These ingredients can give your cookie bars a unique twist. If you need to substitute, here are some ideas: - Use coconut oil instead of butter for a dairy-free option. - Swap brown sugar with coconut sugar for a different taste. - For a gluten-free version, use gluten-free flour. These substitutions keep the recipe fun and flexible. {{ingredient_image_2}} First, you need to preheat your oven to 350°F (175°C). Next, take a 9x13 inch baking pan. Grease it well with non-stick spray. You can also line it with parchment paper. This step helps you remove the bars easily later. In a large bowl, add your softened butter. Then, mix in the brown sugar and granulated sugar. Use an electric mixer on medium speed. Beat the mixture for about 3 to 4 minutes. You want it to look light and fluffy. Now it’s time to add the egg and vanilla extract. Mix until everything is smooth. In another bowl, whisk together the flour, baking soda, and sea salt. Slowly add this dry mix to the wet ingredients. Mix on low speed until just combined. Be careful not to overmix! Gently fold in the chocolate chips, mini marshmallows, and crushed graham crackers. Use a spatula to make sure everything is evenly mixed. Each bite should have a bit of all the good stuff. Pour the cookie dough into your prepared baking pan. Spread it evenly and press it down gently. Place the pan in your preheated oven. Bake for 20 to 25 minutes. The edges should be golden, and the center should feel set. Once baked, remove the pan from the oven. Let it cool for about 10 minutes in the pan. This helps the bars set. After cooling, slice them into bars. For a warm treat, serve them right away. Enjoy the gooey chocolate and marshmallows! To make your S'mores Cookie Bars truly shine, follow these tips: - Use room temperature ingredients: This helps the butter mix well. - Do not overmix the dough: Mix until just combined for soft bars. - Layer the chocolate and marshmallows: Spread some in the dough and top with more before baking. - Watch the baking time: Check at 20 minutes. The edges should be brown, and the center firm. Avoid these common pitfalls for the best results: - Using cold ingredients: Cold butter or eggs will ruin the texture. - Packing the flour: Spoon and level your flour to avoid dense bars. - Not letting cool: Cutting too soon can lead to messy bars. - Skipping the parchment paper: It makes removing the bars easy and neat. Serving your S'mores Cookie Bars can be fun: - Warm them up: Serve right from the oven for gooey treats. - Add toppings: Drizzle with melted chocolate or sprinkle extra marshmallows. - Pair with ice cream: A scoop of vanilla ice cream adds a great touch. - Presentation matters: Use a wooden board for a rustic look. Pro Tips Chill the Dough: For thicker cookie bars, chill the dough in the refrigerator for 30 minutes before baking. This helps the bars maintain their shape and texture during baking. Use Quality Chocolate: Opt for high-quality chocolate chips for a richer flavor. Dark chocolate pairs beautifully with the sweetness of the marshmallows and graham crackers. Don’t Overbake: Keep a close eye on the baking time. The bars will continue to cook as they cool, so it's better to slightly underbake them for a chewy texture. Personalize Your Toppings: Feel free to customize your s'mores cookie bars with different mix-ins like peanut butter chips, nuts, or even a drizzle of caramel for extra indulgence. {{image_4}} You can play with chocolate types in these cookie bars. Use milk chocolate for a sweeter taste. Dark chocolate offers a richer flavor. White chocolate adds creaminess. You can even mix two types for fun. Try using chocolate chunks for big bites. Each option gives a unique twist to your S'mores Cookie Bars. Want to make these cookie bars even better? Add peanut butter chips for a nutty flavor. Chopped nuts like walnuts or pecans add crunch. Dried fruit like cherries or cranberries can bring a sweet tartness. For a minty kick, use mint chocolate chips. Each of these add-ins can change the whole taste. You can make S'mores Cookie Bars gluten-free by swapping all-purpose flour with gluten-free flour. Make sure to check that your chocolate and marshmallows are gluten-free too. For a vegan version, use vegan butter, aquafaba for the egg, and dairy-free chocolate. This way, everyone can enjoy these tasty treats! To keep your S'mores cookie bars fresh, store them in an airtight container. Allow them to cool completely before placing them in the container. This step prevents moisture buildup, which can make your bars soggy. If you plan to eat them within a few days, you can leave them at room temperature. For longer storage, refrigerate them. The best containers for these cookie bars are glass or plastic airtight containers. They keep the bars fresh longer. You can also wrap them tightly in plastic wrap before placing them in a container. If you have a vacuum-sealed bag, that works great too! This method removes air and helps maintain freshness. When you’re ready to enjoy your bars again, reheating them is key. Place a bar on a microwave-safe plate. Heat it in the microwave for 10-15 seconds. This warms it up and melts the chocolate and marshmallows just right. If you prefer, you can reheat them in an oven. Set your oven to 350°F (175°C) and heat for about 5-10 minutes. This enhances the gooey texture! Enjoy your sweet treat warm for the best experience. S'mores Cookie Bars can last up to five days when stored correctly. Keep them in an airtight container at room temperature. This helps keep them soft and gooey. If you want them to last longer, refrigerate them. They can stay fresh for about a week in the fridge. Yes, you can prepare the dough ahead of time. Mix the ingredients as usual, then cover the bowl with plastic wrap. Store it in the fridge for up to 24 hours. When ready to bake, let the dough sit at room temperature for about 15 minutes. This helps it spread evenly in the pan. If you need an egg substitute, try using a flaxseed meal. Mix one tablespoon of flaxseed meal with two and a half tablespoons of water. Let it sit for about five minutes until it thickens. You can also use a quarter cup of applesauce or mashed banana as a good alternative. Yes, you can freeze S'mores Cookie Bars. Cut them into bars before freezing for easy serving. Wrap each bar in plastic wrap and place them in a freezer bag. They can stay fresh for up to three months in the freezer. When you want to eat them, just thaw at room temperature or warm them in the microwave. If you don’t have graham crackers, you can use crushed cookies instead. Try using digestive biscuits or vanilla wafers for a similar taste. Just crush them finely and mix them in like you would with graham crackers. This will still give you that tasty s'mores flavor without missing out. S'mores cookie bars are a fun treat made with simple, tasty ingredients. We covered how to prepare, bake, and enjoy them.

Ingredients
  

  • 1 cup unsalted butter, softened to room temperature
  • 1 cup packed brown sugar, preferably light
  • 1 2/2 cup granulated sugar
  • 1 large egg, at room temperature
  • 2 teaspoons pure vanilla extract
  • 2.25 cups all-purpose flour, spooned and leveled
  • 1 teaspoon baking soda
  • 0.5 teaspoon sea salt
  • 1 cup chocolate chips (your choice of milk or dark chocolate)
  • 1 cup mini marshmallows
  • 1 cup finely crushed graham crackers

Instructions
 

  • Begin by preheating your oven to 350°F (175°C). Prepare a 9x13 inch baking pan by greasing it with non-stick spray or lining it with parchment paper for easy removal of the cookie bars.
  • In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar. Use an electric mixer on medium speed to beat until the mixture is light in color and fluffy in texture, approximately 3-4 minutes.
  • Add the egg and vanilla extract to the creamed mixture, beating well until fully incorporated and smooth.
  • In a separate bowl, whisk together the all-purpose flour, baking soda, and sea salt. Gradually add this dry mixture to the wet ingredients, mixing on low speed until just combined—be careful not to overmix.
  • Gently fold in the chocolate chips, mini marshmallows, and crushed graham crackers using a spatula, ensuring that everything is evenly distributed throughout the dough.
  • Transfer the cookie dough into the prepared baking pan. Spread it out evenly and press it down gently with your hands to create a uniform layer.
  • Place the pan in the preheated oven and bake for 20-25 minutes. The edges should be golden brown, and the center should feel set to the touch. Remember, it will firm up more as it cools.
  • Once baked, remove the pan from the oven and let the cookie bars cool in the pan for about 10 minutes. This will help them set further before cutting.
  • After cooling slightly, slice into bars. For an indulgent treat, serve warm to enjoy the melty chocolate and gooey marshmallows, or allow to cool completely for a firmer texture.

Notes

For an impressive serving suggestion, arrange the cookie bars on a rustic wooden board. Drizzle with extra melted chocolate and scatter additional mini marshmallows on top for a decadent finish that’s sure to catch the eye!
