Easy S’mores Brownies You’ll Want to Make Every Weekend

If you’re anything like me, you crave that nostalgic s’mores flavor all year long. The warm, toasty marshmallows, the sweet chocolate, the buttery graham crackers—it’s pure comfort in a bite. That’s why I came up with these Easy S’mores Brownies, a simple, crowd-pleasing recipe that brings that campfire magic right into your kitchen.

They’re made with a boxed brownie mix (yes, really!) and just a few pantry staples, which means no complicated prep or special skills needed. Whether you’re baking with kids, hosting a potluck, or just treating yourself after a long day, these brownies deliver gooey, chocolatey satisfaction every single time. If you love simple chocolate desserts, you’ll also want to try this Chocolate Sheet Cake—it’s just as rich and easy.

Why You’ll Love These Easy S’mores Brownies

These brownies check all the boxes: simple, quick, and absolutely delicious. I’ve made them for bake sales, family movie nights, and even holiday parties—and they always disappear fast.

Here’s why they’ve become a staple in my home:

• You only need one bowl and one pan. Minimal cleanup means more time for fun (or relaxing on the couch).
• The graham cracker crust adds crunch and flavor that perfectly balances the fudgy brownie base.
• They’re kid-approved and beginner-friendly. My niece made them for her first bake and nailed it!
• You can easily customize them to suit your taste—more marshmallows, different chocolates, or even peanut butter drizzle.

For a different kind of melt-in-your-mouth treat, check out these buttery Whipped Shortbread Cookies—they’re a classic that pairs perfectly with hot cocoa.

Ingredients for the Best S’mores Brownies

To make these Easy S’mores Brownies, you’ll need:

• 5 whole graham crackers
• 1 box of Ghirardelli brownie mix (or your favorite brand)
• ¼ cup water
• ¼ to ½ cup vegetable oil (check your box for the exact amount)
• 1 large egg
• ½ cup semisweet or dark chocolate chips
• 1¼ cups mini marshmallows

If you’re new to baking, don’t overthink the brand. I love Ghirardelli mixes because they’re rich and fudgy, but any good boxed mix will work. Just be sure to follow the directions on the box for the oil, water, and egg amounts—it keeps your brownies moist and perfectly chewy.

If you’re a fan of rich, seasonal flavors, try my Pumpkin Cheesecake Swirl next—it’s creamy, festive, and just as simple.

How to Make Easy S’mores Brownies

You don’t need fancy skills or equipment for this recipe. Just follow these steps and you’ll be sinking your teeth into gooey goodness in no time.

1. Preheat your oven to 325°F. Line an 8×8-inch pan with foil and lightly spray it with nonstick cooking spray.
2. Layer the graham crackers at the bottom of the pan. Break one along the perforations so everything fits snugly.
3. Prepare the brownie batter according to the box instructions using the water, oil, and egg.
4. Spread the batter evenly over the graham crackers.
5. Bake for 35 minutes.
6. Remove from the oven and quickly sprinkle chocolate chips and mini marshmallows evenly on top.
7. Return to the oven for about 5 minutes, or until the marshmallows puff up and turn golden brown.
8. Cool for 20 minutes before cutting. Serve warm for that ooey-gooey texture or at room temperature for clean slices.

That’s it—no complicated techniques or special timing. Just classic, melt-in-your-mouth brownies with a campfire twist. If you love layered treats, my Brown Butter Pecan Pie Bars are another must-try.

Jamie’s Tips for Perfect S’mores Brownies

Every home baker has a few tricks up her sleeve, and I’m happy to share mine to make sure your brownies turn out irresistible every time.

• Don’t overbake. You want the brownies soft and fudgy, not dry.
• Use mini marshmallows—they melt evenly and brown beautifully.
• Line with foil. It makes removing and cutting the brownies so much easier.
• Try different chocolates. White chocolate chips, peanut butter chips, or chopped milk chocolate bars all work great.
• Add a sprinkle of sea salt. It balances the sweetness and makes the chocolate flavor pop.

Family Moments Around a Pan of Brownies

There’s something special about gathering around the kitchen counter, cutting warm brownies, and watching everyone’s faces light up.

My husband always sneaks one before they cool, and my kids fight over the corner pieces. Baking these brownies together has become a small tradition—a quick, easy way to connect without needing a big event.

• Room Temperature: Up to 3 days.
• Refrigerator: Up to 5 days.
• Freezer: Up to 2 months.

Reheat briefly in the microwave and top with ice cream. Or, for another easy fall dessert, try these Pumpkin Pie Bars—they freeze beautifully, too.
