S’mores Brownies

Easy S’Mores Brownies Recipe for Summer – Graham Cracker Crust with Broiled Marshmallows

Growing up in the bustling streets of Marrakech, I learned that the best comfort food comes from simple ingredients and a touch of love. In my recent kitchen tour of the East Village farmers market, I found the perfect graham crackers that reminded me of my childhood, and I thought, why not bring that nostalgic sweetness into a chocolate brownie? Today, I’m sharing my easy summer S’mores brownies that melt instantly under the broiler and taste like campfire memories in the middle of a hot New York summer.

Picture this: a golden crust of crushed graham crackers, the glossy sheen of melted butter, and the faint scent of caramelized sugar that rises as the oven heats. When the brownies emerge, the chocolate chips cling like tiny jewels, and the marshmallows rise and slightly brown, creating a crunchy top layer that crackles under the broiler. The contrast of crunchy, sweet, and fudgy textures turns every bite into a playful adventure, and the chocolate’s richness balances the tangy sweetness of the marshmallow.

I’ve refined this recipe from a few trial runs and learned that a quick broil step gives the marshmallows the perfect golden finish without overcooking the brownies. A common mistake is leaving the brownies on the rack too long; they’ll dry out. The secret is to keep the broiler on high for just a few minutes, watching closely. Trust me—once you try this, you’ll never look back at plain brownies again.

Why This S’mores Brownies Recipe Is the Best

First, the flavor secret comes from the graham cracker crust. Unlike the traditional no‑bake version, my crust adds a subtle crunch and caramel notes that harmonize with the chocolatey base. My training in Paris taught me the importance of layering flavors, and I apply that to this summer dessert, giving it a sophisticated twist while still feeling like a classic campfire treat.

Second, the texture is perfected by baking the brownie batter on top of a buttery crumb base. The batter sets into a moist, fudgy center, and when I broil the marshmallows and chips, they form a glossy, slightly crisp layer that stays on top without soaking into the cake. This two‑layer approach delivers a satisfying bite every time.

Finally, this recipe is foolproof and fast. With a 15‑minute prep, 25‑minute bake, and a quick broil, you’re ready to serve in under an hour. That makes it ideal for spontaneous parties or a quick treat for a busy NYC day. No fancy equipment or obscure ingredients—just pantry staples and a touch of flair.

S’mores Brownies Ingredients

I usually source the graham crackers at a local Middle‑Eastern market in Astoria, where they’re still made with the original recipe from my mother’s kitchen. The marshmallows come from the same place, and the chocolate chips are from a small artisan producer in Brooklyn that melts like butter in your mouth.

Ingredients List

• 1 Package of Graham Crackers (About 12-15 crackers)
• ½ Cup Sugar
• 6 Tbsp. Butter, Melted
• 1 Box of Brownie Mix, Prepared according to Directions
• 1 – 10 oz. Package of Miniature Marshmallows
• 1 Cup of Chocolate Chips

Ingredient Spotlight

Graham Crackers: They provide the crunchy base and caramelized sweetness that anchors the brownie. Look for whole‑wheat versions if you prefer a slightly healthier twist; the texture is still delightful. Substitution: Shortbread cookies crushed for a buttery depth—flavor remains sweet but with a richer crumb.

Miniature Marshmallows: These tiny pillows of fluff rise quickly under the broiler and give that iconic S’mores crunch. If you can’t find mini marshmallows, use regular marshmallows cut into small cubes—just keep an eye on the broil time to avoid burning. Substitution: Marshmallow fluff spread lightly over the top; it melts into a velvety coating but lacks the crisp texture.

Chocolate Chips: They create pockets of melted chocolate that add a glossy, decadent finish. Opt for semi‑dark chips for a less sweet, richer flavor. Substitution: Dark chocolate chunks (70% cacao) offer a more robust chocolate profile with fewer sugars.

How to Make S’mores Brownies — Step-by-Step

Let’s dive into a quick, step‑by‑step guide that keeps the flavors bright and the process simple.

Step 1: Crush Graham Crackers

Place the graham crackers in a food processor and pulse until finely crushed. Aim for a coarse crumb that still holds together when pressed. This texture ensures a firm base without turning into powder.

💡 Stella’s Pro Tip: For a slightly darker crust, toast the crumbs for 2 minutes before pressing.

Step 2: Add Butter & Sugar

Add melted butter and sugar to the crushed crumbs, pulsing again until everything feels slightly wet. The butter binds the crumbs, creating a crumbly yet cohesive mixture.

⚠️ Common Mistake to Avoid: Overmixing can make the base soggy—pulse just enough.

Step 3: Press Crust

Press the graham cracker mixture firmly into the bottom of a parchment‑lined 9×13 baking dish. A tight, even layer ensures the batter stays in place and bakes uniformly.

💡 Stella’s Pro Tip: Use a flat-bottomed glass to press for a perfectly level crust.

Step 4: Prepare Brownie Mix

Whisk the brownie mix with the required amount of water, oil, and eggs, following the package directions. Stir until smooth; avoid over‑whisking to keep the batter airy.

⚠️ Common Mistake to Avoid: Adding too much liquid; it will make the brownies runny.

Step 5: Pour Brownie Mix

Carefully pour the batter over the pressed crust, spreading evenly. The batter should sit on top without mixing into the crumb layer.

💡 Stella’s Pro Tip: Gently tap the pan to release any air pockets.

Step 6: Bake Brownies

Bake at 350°F for 22‑25 minutes, or until a toothpick comes out mostly clean with a few moist crumbs. The brownies should hold together but still be slightly gooey.

⚠️ Common Mistake to Avoid: Overbaking—stop at the first sign of firmness to keep the center moist.

Step 7: Top with Marshmallows & Chips

Immediately after removing from the oven, top the warm brownies with miniature marshmallows and chocolate chips. The heat will begin to melt the chips and slightly soften the marshmallows.

💡 Stella’s Pro Tip: Use an even layer of marshmallows to ensure uniform browning.

Step 8: Broil for Browning

Turn the oven to broil and place the brownies under the broiler for about 3 minutes, or until the marshmallows just start to brown and the chocolate chips melt into a glossy coating.

⚠️ Common Mistake to Avoid: Leaving the broiler on too long—marshmallows can burn quickly.

Serving & Presentation

Let the brownies rest for 10 minutes before cutting to keep the marshmallow topping from sliding off. Slice into squares, then dust each piece with a light sprinkle of cocoa powder or a drizzle of caramel sauce for a luxurious finish. For a pop of color, garnish with a few fresh strawberries or a handful of crushed pistachios—something that reminds me of my Moroccan evenings.

Serve warm from the oven with a scoop of vanilla ice cream for a classic “brownie sundae” or pair with a chilled glass of sparkling rosé, which adds a floral brightness that cuts through the sweetness. The combination of buttery crust, gooey chocolate, and caramelized marshmallows is perfect for a summer gathering or a cozy night in.

Make-Ahead, Storage & Reheating

I often pre‑make these brownies for my office lunch break. Because the marshmallow topping sets quickly, I assemble the crust and batter ahead of time, then bake and broil the day of. For a true make‑ahead, you can store the pre‑baked, un‑topped brownies in a sealed container.

When reheating, I always let the brownies sit at room temperature for 10 minutes to restore moisture. A quick broil not only re‑bakes the marshmallows but also restores that satisfying crackle.

Variations & Easy Swaps

Nutty Brownie Twist

Whisk in ½ cup chopped walnuts into the brownie batter before pouring over the crust. The walnuts add a crunchy, buttery flavor that complements the chocolate and gives the brownies a festive, New York‑style twist—think of the crunchy pistachio croissants from my favorite bakery in Midtown.

Gluten‑Free & Dairy‑Free Version

Replace the boxed brownie mix with a certified gluten‑free blend and use melted coconut oil in place of butter. The result is a moist, chocolatey treat that’s allergy‑friendly yet still indulgent. I’ve tested it on a friend who is lactose‑intolerant, and she loves the nutty, buttery finish.

Summer Berry Twist

Fold 1 cup fresh blueberries into the batter just before baking. The berries burst with juice during cooking, adding a subtle tartness that pairs beautifully with the caramelized marshmallows. This variation feels like a quick summer berry crumble in brownie form.
