They’re incredibly simple to whip up and absolutely crowd-pleasing. Trust me, you’ll want these treats in your dessert repertoire!

Simple & Quick: Ready in about an hour, these brownies come together effortlessly.
Irresistible Flavor: The chocolatey richness pairs beautifully with toasted marshmallows.

Ingredients You’ll Need

5 graham cracker sheets: These provide a delightful crust base that adds a crunchy texture.
1 box of brownie mix for an 8×8 inch pan: A time-saver that gives you a simple foundation for your brownies.
2 egg yolks: These contribute to the fudgy texture, making the brownies rich and moist.
1/2 cup vegetable oil or melted butter: Both will keep the brownies moist; butter adds a depth of flavor.
1/3 cup brewed hot coffee: Enhances chocolate flavor (don’t worry—it won’t taste like coffee!).
1 tsp vanilla extract: A must for elevating sweetness and aroma.
1/4 tsp salt: A pinch of salt balances the sweetness and enhances overall flavor.
1/2 cup chocolate chips: Extra pockets of chocolate make every bite fabulous!
2 cups mini marshmallows: These gooey treats take the brownies to that s’mores level.

How to Make Easy Brownies with Box Mix

Preheat the oven: Set your oven to 325°F and prepare an 8×8 inch baking pan. Line it with parchment paper or aluminum foil, leaving an overhang on the sides for easy removal later.
Prepare the crust: Place the graham cracker sheets in a single layer on the bottom of the pan, breaking them to fit if necessary.
Mix the brownie batter: In a large bowl, combine the brownie mix, egg yolks, hot brewed coffee, vegetable oil or melted butter, vanilla extract, and salt. Stir until just combined, then fold in the chocolate chips for those delightful extra pockets of chocolate.
Bake the brownies: Pour the brownie batter over the layer of graham crackers in the prepared pan and spread it evenly. Bake in the preheated oven for about 40 minutes, until slightly puffed and firm around the edges.
Add marshmallows: Carefully pull the brownies out of the oven and sprinkle the mini marshmallows on top. Return the brownies to the oven and bake for an additional 3-4 minutes, just until the marshmallows begin to puff.
Toast the marshmallows: To achieve that perfect toasted s’mores finish, use a kitchen torch to carefully toast the marshmallows until golden brown. If you don’t have a torch, you can broil them for a few minutes—just be sure to keep a close eye on them to prevent burning.
Cool and slice: Once the marshmallows are beautifully toasted, remove the pan from the oven and let the brownies cool completely before slicing to ensure cleaner cuts. When you’re ready to serve, enjoy these decadent brownies warm!

Storing & Reheating

To keep your brownies fresh, store them at room temperature in an airtight container for up to 3 days. For longer storage, refrigerate them for about a week. You can also freeze brownies for up to 3 months—just wrap them tightly in plastic wrap and foil to prevent freezer burn. When it’s time to enjoy again, simply warm them in the microwave for 15-20 seconds to refresh their gooey goodness. Note that the texture may slightly change after freezing, but they’ll still taste divine!

Chef’s Helpful Tips

Avoid overmixing: When combining the brownie batter, stir just until combined to maintain that fudgy texture.
Let eggs come to room temperature: This step helps achieve better mixing and texture; just let them sit out for 15-30 minutes.
Check for doneness: Use a toothpick to test; it should come out with a few moist crumbs rather than a clean finish for the perfect fudgy brownie.
Play with toppings: Feel free to add crushed nuts or a drizzle of chocolate on top for a fun twist!

Nothing feels as special as a homemade dessert, and these rich, Easy Brownies with Box Mix truly deliver. They’re perfect for satisfying that relentless sweet tooth, whether you’re indulging solo or serving up a treat for friends. Don’t hesitate to experiment with flavors and toppings that suit your taste—you might find a new favorite combination!

Recipe FAQs

Can I use a different size pan for this recipe?

You can adjust the baking time if using a different size pan. A larger pan will require less baking time, while a smaller pan will need longer. Just keep an eye on the brownies, checking for doneness with a toothpick.

Can I make these brownies gluten-free?

Absolutely! Simply use a gluten-free brownie mix and check that your graham crackers are gluten-free as well. You’ll end up with just as delicious of a treat!

What if I don’t have mini marshmallows?

No worries! You can use regular-sized marshmallows cut in half instead. Just be sure to adjust the baking time slightly, as larger marshmallows may take a bit longer to melt.

How do I get the perfect slice?

To achieve clean slices, let the brownies cool completely in the pan before cutting. You can also pour a little hot water over your knife or spatula before slicing to ensure each piece comes out smoothly. Enjoy slicing and sharing these delectable brownies!
