S’mores Brownies Ingredients
Unleash the sweetness with these essential ingredients!
For the Crust
- Graham Crackers – forms a sweet and crunchy base for the brownies; feel free to use gluten-free graham crackers if needed.
- Sugar – adds sweetness to the crust; adjust according to your personal taste preferences.
- Butter (6 tbsp, melted) – binds the crumbs together for a firm crust; coconut oil can be substituted for a dairy-free option.
For the Brownies
- Brownie Mix (1 box) – the cornerstone providing that fudgy texture; you can opt for homemade brownie batter for a personal touch.
- Miniature Marshmallows (10 oz.) – brings that classic S’mores flavor and adds delightful chewiness; look for gluten-free options if necessary.
- Chocolate Chips (1 cup) – intensifies the chocolate richness; experiment with different types of chips like white chocolate or caramel for a fun twist.
Step‑by‑Step Instructions for S’Mores Brownies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C) to ensure it reaches the perfect temperature for baking your S’mores Brownies. While the oven heats up, take a 9×13-inch baking dish and line it with parchment paper, allowing some overhang on the sides for easy removal later. This prepares your dish for an even bake and easy cleanup.
Step 2: Make the Graham Cracker Crust
In a food processor, pulse enough graham crackers to yield about two cups of fine crumbs. Mix these crumbs with melted butter and sugar until the mixture is fully combined and resembles wet sand. Pour this delicious crust mixture into your prepared baking dish, evenly pressing it down with your fingers or the bottom of a measuring cup to create a firm base for your brownies.
Step 3: Prepare the Brownie Mixture
Next, take your brownie mix and prepare it according to the package instructions for optimal fudginess. Once mixed, pour the brownie batter directly over the graham cracker crust you’ve just made. Be sure to spread it evenly using a spatula, ensuring every nook of the crust is covered for a satisfying layer of brownies in your S’mores Brownies.
Step 4: Bake the Brownies
Place the baking dish in your preheated oven and bake for 22–25 minutes. Keep a close eye on them—when the edges look set and a toothpick inserted into the center comes out with a few moist crumbs, your brownies are perfectly baked. Removing them at the right time will yield a delightful fudgy texture.
Step 5: Add the Marshmallows and Chocolate Chips
Once your brownies are out of the oven, immediately scatter the miniature marshmallows and chocolate chips generously on top. The residual heat will start the melting process, creating a gooey topping that adds to the overall decadence of these S’mores Brownies. Allow them to rest for a few minutes, letting the marshmallows puff up beautifully.
Step 6: Broil for Toasted Perfection
Now, switch your oven to the broil setting. Place the brownies back in the oven for about 3 minutes, watching closely to avoid burning. The goal is to achieve that perfect golden-brown color on the marshmallows. This step will give your S’mores Brownies that delightful toasted look and flavor reminiscent of summer campfires.
Step 7: Cool and Slice
After broiling, remove the dish from the oven and let it cool slightly—just about 10 minutes will do. Using the parchment overhang, carefully lift the brownies out of the dish. Allow them to cool completely before slicing into squares for serving. Cutting them while they’re still a little warm makes for a melty and irresistible treat that everyone will love.

Helpful Tricks for S’mores Brownies
- Knife Technique: Spray your knife and spatula with non-stick spray before slicing. This simple tip helps ensure perfectly shaped brownies without sticking.
- Check for Fudginess: To prevent over-baking, start checking your brownies 2-3 minutes before the timer goes off. They should be set but still fudgy in the center!
- Storage Tip: For fresh brownies longer, store them in an airtight container. Placing half a sliced piece of bread inside will keep them moist and delicious.
- Easy Cleanup: Line your baking dish with parchment paper, allowing for easy removal. This little step makes cleanup a breeze and helps keep your brownies intact.
- Adaptable Ingredients: If you need a gluten-free option, simply substitute with gluten-free graham crackers and brownie mix. Your S’mores Brownies will still be delightful!
Make Ahead Options
These Easy S’mores Brownies are perfect for busy weeknights and meal prepping! You can prepare the graham cracker crust up to 24 hours in advance; simply press the mixture into the baking dish and refrigerate it. Additionally, you can mix the brownie batter ahead of time and store it in the fridge for up to 3 days. When you’re ready to bake, just pour the chilled brownie mixture over the crust and proceed with the baking instructions. This way, you’ll save valuable time while still enjoying that delicious, freshly baked taste. To ensure quality, keep the brownies covered and let them cool completely before slicing; this will help maintain their fudgy texture.
