Ingredients You’ll Need

5 graham cracker sheets: These add a delightful crunch and classic s’mores flavor. Feel free to crush them for a finer texture if preferred.
1 box of brownie mix for an 8×8 inch pan: This is the star of the show, making the entire process super convenient. Any brand you enjoy will work well.
2 egg yolks: Adding richness to the brownie batter. This helps achieve that fudgy consistency. You could use whole eggs, but yolks create a denser brownie.
1/2 cup vegetable oil or melted butter: Both will add moisture; choose butter for a richer flavor. Ensure it’s cooled if melted to avoid cooking the eggs.
1/3 cup brewed hot coffee: Enhances the chocolate flavor beautifully. You can substitute with hot water if you’d prefer a milder taste.
1 tsp vanilla extract: This elevates the overall flavor profile. Always opt for pure vanilla extract for the best flavor.
1/4 tsp salt: A pinch of salt balances out the sweetness. Sea salt can be used for added flavor.
1/2 cup chocolate chips: For extra chocolatey goodness, I recommend semi-sweet or dark chocolate chips.
2 cups mini marshmallows: The key to that gooey, marshmallowy top layer. They puff up beautifully in the oven.

How to Make Easy Brownies with Box Mix

Preheat the Oven: Start by preheating your oven to 325°F (165°C). Line an 8×8 inch baking pan with parchment paper or aluminum foil, leaving an overhang so you can lift the brownies out later.
Prepare the Graham Crackers: Place the graham cracker sheets at the bottom of the pan in a single layer. Don’t worry if they break a bit; just fill in the gaps to cover the surface.
Mix the Brownie Batter: In a large bowl, combine the brownie mix, 2 egg yolks, 1/3 cup brewed hot coffee, 1/2 cup vegetable oil or melted butter, 1 teaspoon vanilla extract, and 1/4 teaspoon salt. Stir until just combined. Gently fold in the chocolate chips for that decadent touch.
Bake the Brownies: Pour the brownie batter evenly over the graham crackers in the prepared pan. Bake for about 40 minutes, or until the edges appear set and a toothpick inserted in the center comes out with moist crumbs.
Add the Marshmallows: Carefully pull the brownies out of the oven and sprinkle 2 cups of mini marshmallows over the top. Return them to the oven for another 3-4 minutes until the marshmallows are slightly puffed and begin to melt.
Toast the Marshmallows: Remove the pan from the oven, and using a kitchen torch, gently toast the marshmallows until they’re golden brown and bubbly. If you don’t have a torch, set the pan under the broiler, keeping a close eye to avoid burning, until toasted to your liking.
Cool and Slice: Let the brownies cool completely in the pan before slicing. Using the parchment or foil overhang will make lifting them out much easier!

Storing & Reheating

To store your brownies, keep them at room temperature for up to 3 days, ideally in an airtight container. If you want to extend their shelf life, refrigerate them for up to a week, ensuring they remain in an airtight container to stay fresh. You can even freeze them for up to three months! Just wrap individual squares tightly in plastic wrap and place them in a resealable bag. When you’re ready to enjoy, simply thaw at room temperature or pop them in the microwave for a few seconds to enjoy that freshly baked taste.

Chef’s Helpful Tips

Ensure your egg yolks are at room temperature for better mixing and incorporation into the batter.
Don’t overmix the batter; this can lead to a denser texture—slightly lumpy is perfectly fine!
Allow the marshmallows to cool before cutting, as they’ll be delicate when warm.
If you want a thicker layer of chocolate, add more chocolate chips or use a mini muffin pan for bite-size brownies.
Experiment with adding nuts or different flavored chips like peanut butter or white chocolate for a twist.

Lazy girl s’mores brownies are not only easy to make, but they also balance rich chocolate with sweet marshmallows and crunchy graham crackers beautifully. From the delightful scent wafting through your kitchen while they bake to the gooey, melty bites within, each layer promises to satisfy your sweet tooth. There’s something truly special about this combination that feels both nostalgic and indulgent, perfect for gatherings or simply treating yourself after a long day.

Recipe FAQs

Can I make these brownies gluten-free?

Absolutely! Just use a gluten-free brownie mix in place of regular brownie mix, and you’re set! The graham crackers can also be swapped for gluten-free alternatives.

What can I do if I don’t have a kitchen torch?

If you don’t own a kitchen torch, broiling is a perfect alternative. Just keep close watch while toasting the marshmallows under the broiler, as they can quickly burn in a matter of seconds!

How should I store leftover brownies?

Once cooled, store any leftover brownies in an airtight container at room temperature for up to 3 days. For longer storage, consider freezing them, wrapped tightly in plastic wrap.

Can I add other ingredients to the brownies?

Certainly! Feel free to mix in nuts, different types of chocolate chips, or even crushed candy bars for added flavor and texture. Just remember to keep balance in mind to maintain that delicious texture.
