Ingredients
To make S’mores Brownie Bars, you need fresh and tasty ingredients. Here’s what you’ll need:
– 1/2 cup unsalted butter, melted
– 1 cup granulated sugar
– 2 large eggs
– 1 teaspoon pure vanilla extract
– 1/3 cup unsweetened cocoa powder
– 1 cup all-purpose flour
– 1/4 teaspoon fine sea salt
– 1 cup mini marshmallows
– 1/2 cup semi-sweet chocolate chips
– 1/2 cup crushed graham crackers (plus extra for topping)
– 1/2 cup milk chocolate bar, broken into bite-sized pieces
These ingredients make the bars rich and sweet. The butter gives a soft texture, while sugar adds sweetness. Eggs help bind everything together. Cocoa powder brings that chocolate flavor that everyone loves.
The flour keeps the bars firm, and the salt balances the sweetness. Mini marshmallows add a chewy texture, and chocolate chips bring extra chocolatey goodness. Crushed graham crackers give that classic s’mores crunch. Finally, the milk chocolate pieces melt beautifully on top.
Now you’re ready to gather these ingredients and start your S’mores Brownie Bars adventure!

Step-by-Step Instructions
Preheating and Preparing the Pan
First, preheat your oven to 350°F (175°C). Grab a 9×9 inch baking pan. You can grease it with butter or line it with parchment paper. This will help your brownies come out clean and easy.
Mixing Wet Ingredients
In a large bowl, mix the melted butter and the granulated sugar. Stir until it is smooth. Next, add the two large eggs, one at a time. Mix well after each egg. Finally, stir in the vanilla extract until combined.
Combining Dry Ingredients with Wet Mixture
In another bowl, whisk together the cocoa powder, flour, and sea salt. Make sure they are mixed well. Now, fold this dry mix into your wet mixture. Do this gently to keep the brownies soft.
Folding in S’mores Elements
Now comes the fun part! Gently fold in the mini marshmallows, chocolate chips, and crushed graham crackers. Make sure they spread evenly in the batter. This is what makes it a true s’mores treat.
Baking Instructions
Pour the batter into the prepared pan. Use a spatula to spread it out evenly. Press the milk chocolate pieces into the surface of the batter, letting them sink a bit. Bake in the oven for 25 to 30 minutes. To check if they are done, stick a toothpick in the center. It should come out with a few moist crumbs.
Cooling and Serving Tips
After baking, let the brownies cool in the pan for about 15 minutes. Then, sprinkle more crushed graham crackers and marshmallows on top. For an extra treat, broil it for 1-2 minutes. Keep an eye on it to avoid burning. Let the bars cool completely before cutting them. This makes slicing easier. Enjoy your tasty s’mores brownie bars!
Tips & Tricks
Getting the Perfect Texture
To get the best texture for your s’mores brownie bars, pay close attention when mixing. Mix the wet ingredients until smooth but do not overmix. When folding in dry ingredients, stop as soon as you see no more flour. This keeps your bars soft and chewy. The mini marshmallows and chocolate chips add a great texture contrast, so distribute them evenly in the batter.
Ingredient Substitutions
If you need to switch up some ingredients, here are a few easy swaps:
– Use coconut oil instead of butter for a dairy-free option.
– Try brown sugar instead of granulated sugar for a richer taste.
– Use almond flour if you prefer a gluten-free version. Just remember to adjust the amount to ensure the right consistency.
– For a fun twist, swap the semi-sweet chocolate chips with white chocolate or butterscotch chips.
Serving Suggestions
Serve your s’mores brownie bars warm for a gooey treat. Place them on a rustic wooden platter for a campfire feel. You can garnish with whole graham crackers and fluffy marshmallows around the edges. Drizzle some chocolate sauce on top for extra sweetness. These bars are perfect for camping trips or backyard hangouts. Enjoy them with friends and family!
Pro Tips

Variations
Nutty S’mores Brownie Bars
You can add a nutty twist to your s’mores brownie bars. Chopping nuts adds great flavor. Walnuts or pecans work well. Just mix in half a cup with the other goodies. The nuts give a nice crunch and extra taste.
Gluten-Free Options
If you need a gluten-free version, swap regular flour for almond flour or a gluten-free blend. This change keeps the brownies moist and tasty. Make sure your chocolate chips and graham crackers are also gluten-free.
S’mores Brownie Bars with Peanut Butter
For a rich flavor, try adding peanut butter. Mix in half a cup of creamy peanut butter to the wet ingredients. It adds a great taste and pairs well with chocolate. You can also drizzle some on top before baking for a fun design.

Best Storage Practices
To keep your S’mores Brownie Bars fresh, store them in an airtight container. Layer parchment paper between bars to prevent sticking. Keep the container at room temperature for up to three days. If you want to keep them longer, refrigeration is an option. Just remember, cold storage can affect the texture.
Reheating Instructions
If you want to enjoy a warm brownie bar, simply reheat them in the microwave. Place a bar on a microwave-safe plate and heat for about 10-15 seconds. Check regularly to avoid overheating. This quick method makes the chocolate melt again and gives a gooey experience.
Freezing S’mores Brownie Bars
You can freeze these treats for up to three months. First, cut the brownie bars into squares. Wrap each square in plastic wrap, then place them in a freezer bag. When ready to eat, thaw them in the fridge overnight. You can also reheat them after thawing for a warm treat.
