Taking a cue from nostalgic campfire memories, these S'mores brownies transform the classic outdoor treat into an irresistible layered dessert. Each bite delivers the perfect combination of crunchy graham crackers, rich fudgy brownie, and gooey toasted marshmallows, all crowned with melted chocolate bars that take me right back to those summer evening bonfires.

Last weekend, I brought these to a backyard gathering, and watching adults' faces light up with childhood memories as they bit into these brownies was priceless. Even my pickiest nephew, who usually scrapes frosting off everything, devoured two squares without coming up for air.

Essential Ingredients Guide

  • Premium unsalted butter: creates a rich foundation - room temperature results in better incorporation and smoother texture
  • High-quality cocoa powder: brings intense chocolate depth - Dutch-processed offers a more sophisticated flavor profile
  • Fresh graham crackers: provide the perfect crisp base - store-brand works just as well as name-brand here
  • Mini marshmallows: create an even topping - they melt more uniformly than large ones
  • Hershey's bars: add that authentic s'mores touch - their unique melt pattern is part of the magic

I've found that splurging on good cocoa powder makes the biggest difference in the final taste. After trying countless brands, Dutch-processed cocoa consistently delivers that deep, complex chocolate flavor we all crave.

Creating S'mores Magic

Prepare Your Foundation:
Carefully arrange graham crackers in your lined pan, breaking pieces to fit snugly. This base layer sets the stage for everything that follows.
Create Chocolate Harmony:
Gently melt butter and chocolate together, stirring periodically until smooth and glossy. This step requires patience for the perfect consistency.
Build The Heart:
Mix your sugar into the chocolate mixture, allowing it to cool slightly before incorporating eggs. This timing is crucial for the perfect texture.
Layer With Love:
Spread the brownie batter evenly over your graham cracker base, ensuring it reaches all corners for consistent baking.
Add The Crown:
Top partially baked brownies with a generous layer of mini marshmallows and chocolate pieces, creating that classic s'mores appearance.
Final Transformation:
Return to the oven for the magical moment when marshmallows turn golden and chocolate begins to melt.

My first attempt at these brownies taught me the importance of patience - rushing the cooling process resulted in a messy (though still delicious) situation. Now I know that perfect squares require complete cooling.

Perfect Presentation

Transform these layered delights into an elegant dessert by serving them slightly warmed alongside vanilla bean ice cream. For casual gatherings, I arrange them on a rustic wooden board with scattered graham cracker pieces and a few toasted marshmallows. During summer parties, I love setting up a brownie sundae bar with warm chocolate sauce, caramel drizzle, and whipped cream for guests to customize their treats.

Sweet Adaptations

After countless requests from friends with dietary restrictions, I've discovered several delicious variations. Using gluten-free graham crackers and a one-to-one gluten-free flour blend creates an equally impressive treat. For an extra indulgent version, try spreading a thin layer of peanut butter between the graham base and brownie layer - it adds an unexpected but delightful twist that chocolate-peanut butter lovers can't resist.

Treat Storage Success

Store these beauties in an airtight container at room temperature for up to 3 days, though the graham crackers may soften slightly. For optimal freshness, place them in the refrigerator where they'll keep for up to a week. When ready to serve, let them come to room temperature for about 30 minutes, or warm individual pieces in the microwave for 10-15 seconds for that fresh-baked experience.

S'mores Through Seasons

These brownies have become my go-to dessert for every season. In winter, they bring the warmth of summer campfires indoors. During spring, they're perfect for picnics and outdoor gatherings. Summer barbecues wouldn't be complete without them, and they're a hit at fall harvest parties when paired with hot apple cider.

Childhood Memories Renewed

Creating these brownies always takes me back to childhood camping trips, where perfecting the art of marshmallow toasting was a serious business. Now, watching my own children's eyes light up as they help sprinkle chocolate pieces on top brings those memories full circle, creating new traditions in our kitchen.

Baker's Wisdom

  • Let your melted chocolate mixture cool slightly before adding eggs to prevent them from cooking prematurely
  • Score your brownies with a warm knife before cutting completely through for clean, professional-looking squares
  • Keep a close eye during the final marshmallow toasting - they can go from perfect to burnt in seconds

Making these s'mores brownies has taught me that sometimes the best recipes come from reimagining cherished childhood treats. The combination of familiar flavors in an elevated form creates something truly special - a dessert that bridges generations and brings people together, one gooey, chocolatey bite at a time.

Frequently Asked Questions

→ Can I use boxed brownie mix instead?
Yes, you can use your favorite boxed brownie mix for the middle layer. Just prepare it according to package directions and pour over the graham cracker base.
→ Why do you recommend a metal pan over glass?
Metal pans conduct heat more evenly and help achieve better brownie edges. Glass pans can cause uneven baking and may require different baking times.
→ Can I make these ahead of time?
Yes! These brownies stay fresh in an airtight container at room temperature for up to 5 days.
→ Can I use marshmallow fluff instead of mini marshmallows?
Yes, you can spread marshmallow fluff over the partially baked brownies instead of using mini marshmallows.
→ Why do the eggs need to be room temperature?
Room temperature eggs blend better with the batter and help create the right texture. Cold eggs can make your melted chocolate seize up.

Category: Sweet Treats

Difficulty: Intermediate

Cuisine: American

Yield: 16 Servings (16 brownies)

Dietary: Vegetarian

Ingredients

→ Graham Cracker Base

01 5 whole graham cracker sheets

→ Brownie Layer

02 ½ cup unsalted butter (113g)
03 ½ cup semi-sweet chocolate chips (85g)
04 1 cup sugar (200g)
05 2 large eggs, at room temperature
06 ½ cup unsweetened or Dutch processed cocoa powder (40g)
07 1 teaspoon vanilla extract
08 ¼ teaspoon salt
09 ½ cup all-purpose flour (60g)

→ S'mores Topping

10 1 - 1½ cups mini marshmallows (45-68g)
11 1 Hershey's chocolate bar (1.55 oz)
12 1 graham cracker, roughly crushed

Instructions

Step 01

Heat your oven to 350°F (177°C). Take your 8x8 metal pan and line it with parchment paper, making sure it covers the bottom and runs up two sides.

Step 02

Line the bottom of your pan with whole graham crackers. Break pieces as needed to fill in any gaps - you want complete coverage.

Step 03

In a large microwave-safe bowl, combine butter and chocolate chips. Heat in 30-second bursts, stirring between each, until everything's melted and smooth.

Step 04

Stir sugar into your chocolate mixture just until combined. Pop it back in the microwave for 1 minute. Mix thoroughly and let it cool for about 5 minutes if it's too hot.

Step 05

Beat in eggs vigorously for one minute until the batter falls in ribbons. Add vanilla, cocoa powder, and salt, whisking until glossy. Fold in flour until just combined.

Step 06

Pour your brownie batter over the graham crackers and smooth the top. Bake for 25 minutes - they'll still need another bake after toppings.

Step 07

Top your partially baked brownies with mini marshmallows, crushed graham crackers, and pieces of chocolate bar. Return to the oven for 8-10 more minutes.

Step 08

Let the brownies cool in the pan for 1 hour. Use the parchment paper to lift them out, then cut into squares.

Notes

  1. Store these treats in an airtight container at room temperature for up to 5 days
