Essential Ingredients You’ll Need

Pantry Staples: What You Likely Already Have

To keep this smores brownies recipe easy and accessible, we’ve designed it around ingredients you probably already have in your pantry. The base is a classic fudge brownie mix—you can use a brand like Betty Crocker®, or your favorite store version. This shortcut guarantees rich, chocolatey flavor without the need to melt down multiple types of chocolate or cocoa powder.

Here’s what you’ll need for the brownie layer:

Ingredient	Amount	Notes
Fudge brownie mix	1 (16-ounce) package	Any trusted brand will work
Vegetable oil	½ cup	Helps with a moist texture
Large eggs	2	Bind everything together
Water	3 tablespoons	Just enough to hydrate the mix

These ingredients work together to create a dense, moist foundation that balances beautifully with the topping. If you’re wondering whether you can make smores brownies with box mix, the answer is yes—and you’ll never know the difference.

Breaking Down the SMores Topping

Now comes the fun part—the gooey, toasty topping that transforms these brownies from basic to unforgettable. This layer is where all the magic happens, so don’t skimp here. You’ll need:

Topping Component	Amount	Purpose
Graham crackers	6 full crackers, broken	Adds that signature crunch
Miniature marshmallows	1 ½ cups	Toasts to golden perfection
Milk chocolate bars	8 bars (1.5 oz each), chopped	Melt into pools of chocolate heaven

We’ve found that using whole milk chocolate bars, coarsely chopped, delivers that melt-in-your-mouth consistency that smores brownies with marshmallows absolutely require. And yes, you can use chocolate chips in a pinch, but for that nostalgic campfire flavor, bars work best.

Pro tip: Don’t break the graham crackers too finely. You want that chunky texture to mimic real smores. Toss everything together in a bowl while the brownies start baking—this timing ensures your topping doesn’t overbake or dry out.

Whether you’re a first-time baker or a dessert pro, these ingredients bring together flavor, texture, and visual appeal in every bite.

Step-by-Step Instructions for Perfect SMores Brownies

Brownie Batter Basics: From Box Mix to Wow

If you’re asking, “Can I make smores brownies with box mix?” — absolutely! In fact, this entire recipe is based on that very concept. It’s the quickest way to guarantee rich, chocolatey flavor without sacrificing texture or taste.

Start by gathering your ingredients and preheating your oven to 350°F (175°C). You’ll need a 9×13-inch baking dish—a must-have for ensuring the brownies are thick enough to hold the smores topping without collapsing.

Here’s how to mix the base:

1. In a medium mixing bowl, add the brownie mix, ½ cup vegetable oil, 2 large eggs, and 3 tablespoons of water.
2. Stir the mixture with a wooden spoon or silicone spatula until everything is well blended—no dry mix or streaks of egg.
3. Pour the batter evenly into the greased 9×13 baking dish. Use a spatula to spread it out so it reaches all corners.

Your kitchen will already smell amazing—and we haven’t even added the topping yet.

Bake the brownies for 15 minutes. This partial bake is crucial. It allows the bottom to firm up just enough before you add the gooey top layer. You’re not fully baking yet—just giving it a solid foundation.

Assembling the Ultimate Marshmallow-Graham Topping

While your brownie layer bakes, it’s time to prepare that epic smores topping. This part is so simple yet so satisfying.

1. In a large bowl, break up 6 graham crackers into 1-inch chunks. You want bite-size pieces, not dust.
2. Toss in 1½ cups of mini marshmallows.
3. Coarsely chop 8 milk chocolate bars (1.5 oz each) and mix them in. The key here is not over-mixing—just combine gently.

Once the brownies come out of the oven after their initial 15-minute bake, immediately sprinkle this topping evenly across the surface. Push the pieces gently into the soft brownie layer so they stick without sinking too deep.

Now, place the pan back into the oven and bake for another 7–10 minutes. Keep a close eye during this stage—you’re aiming for:

• Marshmallows puffed and slightly golden
• Chocolate slightly melted but still intact
• Graham crackers slightly toasted on edges

Use a toothpick inserted 2 inches from the side of the pan to check doneness—it should come out mostly clean, with a few moist crumbs but no raw batter.

Once baked, let the brownies cool in the pan for at least 20–30 minutes. This sets the structure and ensures clean slices (if you can resist diving in!).

Tools & Tips for Baking Perfection

Must-Have Tools for Best Results

You don’t need a full bakery setup to pull off these crowd-pleasing smores brownies. In fact, most kitchens already have the essentials. That said, a few specific tools can take your brownies from “pretty good” to “absolutely perfect.”

Tool	Why You Need It
9×13-inch baking dish	Provides even heat distribution and ideal slice height
Silicone spatula	Helps mix and spread the batter without overworking it
Large mixing bowl	Needed for both the batter and the smores topping
Offset spatula (optional)	Great for smoothing the batter and topping evenly
Toothpick or cake tester	Ensures perfect doneness without cutting the brownie
Cooling rack	Speeds up cooling while preventing sogginess

If you’re serious about presentation, a hot knife or plastic brownie knife helps keep your slices clean and gooey centers intact.

Pro Tips to Avoid Common Mistakes

Even the best bakers sometimes run into brownie problems—burnt tops, sunken centers, or overbaked edges.

1. Pre-bake timing is everything
You only need to bake the brownies for 15 minutes before adding the topping. This gives them structure without fully setting the center. If you wait too long, the marshmallows won’t bond well—and if you add them too early, they may melt completely.

2. Don’t walk away during the final 7–10 minutes
Keep your eye on the marshmallows to prevent over-browning. You want them golden, not torched.

3. Cool before slicing
We get it—the smell is torture. But letting the brownies cool for at least 30 minutes makes slicing clean and prevents marshmallow tearing.

4. Use parchment for easy removal
Line your 9×13 pan with parchment paper, letting it overhang on two sides. This creates a sling that lets you lift the entire batch out for cooling and slicing.

5. Upgrade your box mix
Yes, this is a smores brownies with box mix recipe, but that doesn’t mean it has to taste store-bought. Consider adding a teaspoon of espresso powder or a splash of vanilla extract to deepen the flavor.

Bonus Hack: Want ultra-gooey marshmallows? Try broiling the top for 30–45 seconds after baking. Just watch closely—things move fast under the broiler!

Serving, Storing & Reheating

Best Ways to Serve Your Brownies

There’s no wrong way to enjoy smores brownies, but the way you serve them can enhance the experience. Fresh out of the oven? Pair them with a scoop of vanilla ice cream and a drizzle of chocolate syrup for a warm, melty dessert you’ll crave all week.

For casual events or picnics, cut the 9×13 tray into 12 or 15 squares. These brownies hold their shape well and don’t need utensils—just napkins and hungry hands.

Want a fancy touch? Plate the brownies with a dollop of whipped cream, a few crushed graham cracker crumbs, and a square of Hershey’s chocolate on top. Restaurant-quality, zero stress.

How to Store for Freshness

Brownies are best when fresh—but that doesn’t mean you can’t make them ahead. Here’s how to store smores brownies with marshmallows so they stay soft and gooey.

Refrigerator:
If your kitchen is warm or humid, refrigerate the brownies for up to 5 days. Let them come to room temp before serving, or microwave for 10–15 seconds to restore gooeyness.

Pro Tip: The marshmallows may stiffen in the fridge, so warming them slightly always helps bring back that original texture.

Can You Freeze SMores Brownies?

Yes—and they freeze surprisingly well.

To freeze:

1. Let the brownies cool completely.
2. Cut them into portions and wrap each piece tightly in plastic wrap.
3. Store wrapped pieces in a freezer-safe zip-top bag or airtight container.

To enjoy again, just let one thaw at room temp for about an hour or microwave for 20–30 seconds. The marshmallows soften, the chocolate melts slightly, and the result is nearly as good as freshly baked.

Troubleshooting Common Problems

Why Did My Marshmallows Burn?

Burnt marshmallows are one of the most common issues in smores brownies, especially when baked too long or too close to the top heating element. But don’t worry—this is an easy fix.

Here’s what likely happened:

• You added the topping too early (before pre-baking the brownie layer).
• The marshmallows were sitting too close to the broiler or upper coils.
• Baking went past the recommended 7–10 minutes after topping.

Fix it:
Keep a close eye during the last 5 minutes of baking. You’re looking for light golden edges and puffy marshmallows—not dark brown or black. If you notice them browning quickly, lightly tent the pan with foil.

Fixing Dense or Dry Brownies

Brownies too dry or dense? It happens, especially when overbaked or if the mix isn’t hydrated enough. This is especially relevant for smores brownies with box mix, since different brands bake differently.

Common causes:

• Overmixing the batter (which develops too much gluten).
• Overbaking the brownies before adding the topping.
• Using cold eggs or oil, which don’t incorporate as smoothly.

Fix it:

• Undermix slightly—just until everything is combined.
• Set a timer and pull brownies at the lower end of the time range (15 mins + 7 mins max).
• Consider adding a spoonful of plain Greek yogurt or a splash of milk to the batter for added moisture.

And remember: even slightly overbaked brownies can be saved. Serve them warm with ice cream, or microwave slices individually with a damp paper towel for 10 seconds.

Marshmallows Melted Into the Brownie?

This often happens if you add them too early or don’t pre-bake the brownie layer first. The key to perfect marshmallow topping is timing.

Pro tip: Always wait until after the first 15 minutes of baking to add the smores topping. This ensures the base is set enough to hold the toppings on the surface.

Chocolate Didn’t Melt Properly?

If your chocolate bars didn’t get that smooth melt, you may have:

• Used chocolate chips instead of chopped bars
• Overbaked or baked too hot
• Added cold chocolate pieces

Solution: Use coarsely chopped chocolate bars and let them come to room temp before mixing into the topping. This helps them soften and melt more evenly once they hit the warm brownie layer.

Nutrition Facts & Healthier Swaps

Smart Ingredient Substitutions

Looking to make your smores brownies recipe easy and a little healthier without losing that classic gooey experience? These simple swaps do the trick:

1. Use Greek Yogurt Instead of Oil

Replace half of the vegetable oil with unsweetened Greek yogurt for extra moisture and less fat. It also adds a slight protein boost.

2. Swap Milk Chocolate with Dark Chocolate

Not only do you get a richer flavor, but dark chocolate is also packed with antioxidants.

3. Try Whole Wheat Graham Crackers

Substitute traditional graham crackers with whole wheat or gluten-free versions. It adds fiber and works great with the gooey topping.

4. Use Mini Vegan Marshmallows

Want a dairy-free or vegetarian-friendly version? Use plant-based marshmallows (like Dandies). They toast beautifully and keep the dessert inclusive.

5. Go Low-Sugar Mix

Many brands now offer low-sugar or keto brownie mixes that still deliver great flavor. Just be sure to monitor baking time, as some may set faster.
