These ingredients lay the base for a rich brownie. - 1 cup graham cracker crumbs - 1/2 cup unsalted butter, melted - 1 cup mini marshmallows - 1 cup milk chocolate chips Next, let’s focus on the S’mores components. The graham cracker crumbs create the crust. Mix them with melted butter until fully combined. This mix will form a solid base. The mini marshmallows and milk chocolate chips will melt beautifully. They add that classic S’mores taste. Together, these ingredients make each bite a delight. {{ingredient_image_1}} First, preheat your oven to 350°F (175°C). This heat will help bake the brownies just right. Next, grab a 9x13 inch baking pan. You can grease it with butter or line it with parchment paper. Lining it with paper helps you lift the bars out later. Leave some paper hanging over the edges for easy removal. In a mixing bowl, add 1 cup of graham cracker crumbs. Then, pour in 1/2 cup of melted unsalted butter. Mix them well until the crumbs look shiny. Now, press this mixture into the bottom of your prepared pan. Use your hands to make it even. This crust will give your bars that classic S’mores taste. Now, it's time to make the brownie batter. Follow the box instructions for the brownie mix. Don't forget to add 1/2 teaspoon of vanilla extract and a pinch of salt. These extras add great flavor. Pour the brownie batter over your graham cracker crust. Bake it in the oven for 20 to 25 minutes. Check for doneness by inserting a toothpick. If it comes out with a few moist crumbs, it’s ready. When the brownies are done, sprinkle 1 cup of milk chocolate chips and 1 cup of mini marshmallows on top. Return the pan to the oven for another 5 to 7 minutes. Watch the marshmallows puff up and turn golden. Once they look perfect, take the pan out. Let the brownies cool for 10 minutes before moving them to a wire rack. After they cool completely, lift them out using the parchment paper. Cut them into squares or bars and enjoy! To check for doneness, use a toothpick. Insert it into the center of the brownies. If it comes out with a few moist crumbs, they are ready. If it comes out clean, they are overbaked. You want that perfect balance. To avoid overbaking, keep an eye on the time. Set a timer for 20 minutes. Start checking for doneness at that point. Remember, the brownies will continue to cook a bit after you take them out. You can add extra ingredients to boost flavor. Consider mixing in some chopped nuts or swapping dark chocolate chips for milk chocolate. You can also try adding a spoon of peanut butter to the brownie mix for a nutty taste. For serving suggestions, present these bars on a rustic wooden board. Drizzle with chocolate sauce for a rich touch. Garnish with extra mini marshmallows on top for a fun look. This makes each bite even more inviting! Pro Tips Use High-Quality Chocolate: Opt for high-quality milk chocolate chips for a richer flavor that complements the sweetness of the marshmallows. Don’t Overbake: Keep a close eye on the brownies while baking; removing them when they still have a few moist crumbs ensures a fudgy texture. Cool Before Cutting: Allow the bars to cool completely before cutting to ensure clean edges and prevent them from falling apart. Experiment with Toppings: Feel free to add extra toppings like crushed graham crackers or a drizzle of caramel for an added twist on the classic s’mores flavor. {{image_2}} You can make S’mores brownie bars even more fun. Add peanut butter for a rich taste. Swirl it into the brownie batter before baking. You can also drizzle caramel on top after baking. This adds a sweet layer that pairs well with chocolate. Try different types of chocolate too. Use dark chocolate chips for a more intense flavor. Or mix in white chocolate chips for a creamy touch. Each chocolate type can change the taste and feel of your bars. Get creative with your toppings! Instead of mini marshmallows, use flavored marshmallows. They come in many fun flavors like strawberry or coconut. This twist can surprise your taste buds. You can also try other candies. Consider adding crushed candy bars or sprinkles for extra crunch. Explore different cracker bases too. You can use chocolate graham crackers instead. This gives a deeper chocolate flavor. Or try vanilla wafers for a lighter touch. Each option changes the texture and taste of your bars. To keep your S'mores brownie bars fresh, store them in an airtight container. Make sure they cool completely first. This helps maintain their soft texture. You can layer the bars with parchment paper. This will prevent sticking. These bars stay fresh for about 4 to 5 days at room temperature.
