Step‑by‑Step Instructions for Graham Cracker S’mores Brownie Bars

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Graham Cracker S’mores Brownie Bars bake evenly and develop that delicious, fudgy texture. While the oven heats up, gather your ingredients and greased 9×13-inch baking pan, so you’re ready to move on quickly.

Step 2: Melt Butter and Chocolate
In a large mixing bowl, combine the butter and semi-sweet chocolate chips. Microwave them together in 30-second increments, stirring after each interval until the mixture is smooth and glossy, typically taking about 1 to 2 minutes. This melted mixture will form the rich base for your brownie bars.

Step 3: Incorporate Eggs and Vanilla
Once your chocolate and butter mixture is melted and combined, stir in the vanilla extract and eggs. Mix these ingredients vigorously until they are fully blended and the batter is shiny. This step is crucial for providing your Graham Cracker S’mores Brownie Bars with the perfect structure and gooeyness.

Step 4: Mix in Dry Ingredients
Now it’s time to add the dry ingredients: granulated sugar, all-purpose flour, baking soda, and ground cinnamon. Gently fold these ingredients into the wet mixture until just combined. Be careful not to overmix, as this will keep your bars light and chewy with that decadent chocolate flavor shining through.

Step 5: Add Chocolate and Prepare to Bake
Fold in 1½ chopped Hershey Bars into your batter for extra chocolatey delight. Pour the brownie mixture into the greased baking pan, spreading it evenly with a spatula. Ensure the mixture reaches the corners of the pan for consistent baking, creating perfectly shaped Graham Cracker S’mores Brownie Bars.

Step 6: Bake the Brownies
Place the pan in your preheated oven and bake for about 20 minutes. Keep an eye out for visual cues; the edges should be set, while the center will look slightly underbaked. A toothpick inserted into the center should come out with a few moist crumbs, indicating a fudgy texture.

Step 7: Cool and Add Toppings
Once baked, remove the brownies from the oven and let them cool briefly. Before they cool completely, sprinkle the remaining chopped Hershey Bars, crumbled graham crackers, and miniature marshmallows on top. This layer will become the gooey, sweet topping for your delightful bars.

Step 8: Broil for Toasty Goodness
Transfer your pan back into the oven and set to broil. Broil for just 1 to 2 minutes, keeping a close watch, as the marshmallows can burn quickly. Once they are beautifully toasted and golden brown, remove the pan from the oven and let it cool for a few minutes.

Step 9: Slice and Serve
After cooling slightly, use a sharp knife to cut your Graham Cracker S’mores Brownie Bars into squares. Allow them to cool further if desired, then serve warm or at room temperature. These ooey-gooey treats are perfect for sharing and will definitely satisfy your sweet tooth!

Make Ahead Options

These Graham Cracker S’mores Brownie Bars are perfect for meal prepping, allowing you to enjoy a delicious dessert with minimal last-minute effort! You can mix the brownie batter up to 24 hours in advance; simply cover it tightly and refrigerate to maintain freshness. Additionally, you can pre-chop the Hershey Bars and graham crackers to save even more time before baking. When you’re ready to bake, just pour the chilled batter into the baking pan, sprinkle the toppings on, and broil as directed. This way, you’ll have your gooey, chocolatey bars ready to impress in no time, making busy weeknights a little sweeter!

Expert Tips for Graham Cracker S’mores Brownie Bars

Control the Heat: Be cautious while broiling the marshmallows, as they can burn in seconds. Keep the oven door slightly ajar for better visibility.
Perfect Melt: Make sure your chocolate chips and butter are completely melted and combined before adding other ingredients to prevent lumps in your brownie batter.
Don’t Overmix: When combining the wet and dry ingredients, mix gently. Overmixing can lead to dense brownies rather than the desired chewy texture.
Customize with Toppings: Feel free to experiment with different chocolate bars or add nuts for extra crunch. These additions can elevate your Graham Cracker S’mores Brownie Bars to new flavor heights.
Storage Secrets: To maintain the gooeyness of your bars, place parchment paper between layers when storing in an airtight container. This prevents sticking and keeps them fresh.
Served Best: For an even more indulgent treat, serve warm with a scoop of vanilla ice cream or a dollop of whipped cream. It’s the perfect pairing for your brownies!

What if my brownies are too dense or dry?
If you find that your Graham Cracker S’mores Brownie Bars are too dense, it might be due to overmixing the batter or baking them too long. Always mix wet and dry ingredients just until combined to keep the structure light. Check for doneness a couple of minutes early, aiming for a toothpick that comes out with moist crumbs.

Are there any allergy considerations for this recipe?
Definitely! If you’re baking for someone with allergies, it’s important to substitute ingredients accordingly. For a nut allergy, ensure your graham crackers and chocolate are nut-free.
