Enjoy picking the best ingredients for your S’mores Brownie Bars! {{ingredient_image_1}} 1. Preheating the oven: Start by turning your oven to 350°F (175°C). This temperature helps the brownies bake evenly. 2. Lining the baking dish with parchment paper: Grab a 9x13-inch baking dish. Line the bottom and sides with parchment paper. Let the paper hang over the edges. This will make it easy to lift the brownies out later. 1. Combining wet ingredients: In a large bowl, mix melted butter, granulated sugar, and brown sugar. Whisk until everything is blended. 2. Incorporating dry ingredients: In another bowl, sift together the flour, cocoa powder, baking powder, and salt. Slowly add this mix to the wet ingredients. Stir gently until just combined. 3. Adding graham cracker crumbs and chocolate chips: Fold in graham cracker crumbs and chocolate chips. Make sure they are evenly spread through the batter. 1. Layering the brownie batter: Pour half of the brownie batter into your lined baking dish. Spread it out evenly using a spatula. 2. Adding marshmallows and chocolate: Sprinkle mini marshmallows and chopped milk chocolate bars over the first layer. Add half of the remaining graham cracker crumbs on top. 3. Topping with remaining brownie batter: Pour the rest of the brownie batter over the marshmallows and chocolate. Spread it out gently, covering everything. 1. Baking time and temperature: Place the dish in the oven. Bake for 25-30 minutes. 2. Testing for doneness: To check if they are done, insert a toothpick into the center. It should come out with moist crumbs. Remember, it might not be clean because of the gooey marshmallows. To make your S’mores Brownie Bars even more delicious, add extra marshmallows. You can layer them on top or mix them into the batter. This gives a gooey texture and sweet taste. Try different types of chocolate too. Use dark chocolate for a rich flavor or white chocolate for a sweet twist. Mixing these chocolates can create a fun flavor blend. Prevent overmixing your batter. Mix just until the dry ingredients blend in. Overmixing can make the brownies tough. Cool the brownies properly for the best texture. Let them sit in the pan for about 15 minutes. Then, transfer them to a wire rack. Cooling helps them set and makes cutting easier. Get creative with toppings! Try drizzling caramel sauce or chocolate syrup on top. You can also add crushed graham crackers for crunch. Pair these bars with ice cream. Vanilla or caramel ice cream works great. The cold ice cream balances the warm, gooey brownies perfectly. Pro Tips Use Room Temperature Eggs: Allow your eggs to come to room temperature before mixing. This helps create a smoother batter and improves the overall texture of the brownies. Don’t Overmix: When combining the dry and wet ingredients, mix until just combined. Overmixing can lead to dense brownies instead of the desired fudgy texture. Let Them Cool: Allow the brownies to cool completely in the pan before cutting. This helps them set up properly, making it easier to achieve clean cuts. Customize Toppings: Feel free to experiment with different toppings like peanut butter chips, butterscotch chips, or even a sprinkle of sea salt for added flavor. {{image_2}} You can make these S’mores Brownie Bars gluten-free. Use gluten-free flour instead of all-purpose flour. This swap keeps the bars tasty and chewy. Be sure to check your flour blend. Some blends work better than others for baking. If you want a vegan version, it’s easy! Replace the eggs with flaxseed meal. Mix one tablespoon of flaxseed meal with three tablespoons of water. Let it sit for a few minutes until it thickens. For dairy-free options, use coconut oil instead of butter. Choose dairy-free chocolate chips too. Want to add a twist? You can mix in nuts like walnuts or pecans. They add a nice crunch. You can also add different candies or even peanut butter chips. Try adding a pinch of cinnamon for a warm flavor. The options are endless! To keep your S’mores brownie bars fresh, store them in an airtight container. This helps lock in moisture. You can keep them at room temperature for up to three days. If you want them to last longer, refrigerate them for up to a week. For the best results, layer parchment paper between the bars. This prevents them from sticking together. A glass container works great as it keeps the bars soft while letting them breathe. If you want to save some for later, freezing is a great option. First, cut the bars into pieces. Wrap each piece in plastic wrap. Then, place the wrapped bars in a freezer-safe bag. Make sure to remove as much air as possible. This keeps them from getting freezer burn. You can freeze them for up to three months. When you want to enjoy them again, take the bars out and let them thaw in the fridge overnight. You can also let them sit at room temperature for a couple of hours. Either way, they will taste just as good! You can check if your S’mores Brownie Bars are done by using a toothpick. Insert it into the center of the bars. If it comes out with some moist crumbs, they are ready. The toothpick may not come out clean due to the gooey marshmallows. Keep an eye on the time as you bake them for 25-30 minutes. Yes, you can make S’mores Brownie Bars ahead of time. They taste great even after a day or two. Just let them cool completely, and store them in an airtight container. This way, they remain fresh and tasty. You can also freeze them for longer storage. Just remember to wrap them well.
