Ingredients You’ll Need

5 graham cracker sheets: These create a delicious base with a subtle crunch. Feel free to use honey or regular graham crackers depending on your preference.
1 box of brownie mix for an 8×8 inch pan: A classic and convenient base that saves time and guarantees perfectly fudgy brownies.
2 egg yolks: Adds richness and helps bind the brownies without being too cakey.
1/2 cup vegetable oil or melted butter: Oil keeps them ultra moist, but for a richer taste, melted butter is a great substitute.
1/3 cup brewed hot coffee: Enhances the chocolate flavor by balancing sweetness and bringing depth. If you’re sensitive to caffeine, use decaf coffee.
1 tsp vanilla extract: A must-have flavor enhancer that rounds out the taste wonderfully.
1/4 tsp salt: Elevates the sweetness and balances all the flavors.
1/2 cup chocolate chips: More chocolate means more indulgence! Use semisweet or dark chocolate chips for a decadent finish.
2 cups mini marshmallows: These will be the crowning glory, providing that gooey, s’mores-like experience we all adore.

How to Make Easy Brownies with Box Mix

Preheat the oven: Set it to 325°F (162°C). Line the bottom of an 8×8 inch baking pan with parchment paper or aluminum foil, leaving some overhang to make removal simple later.
Prepare the graham cracker base: Place the 5 graham cracker sheets in a single layer on the bottom of the pan, breaking them if necessary to fit the entire surface.
Mix the brownie batter: In a large mixing bowl, combine the box of brownie mix, 2 egg yolks, 1/2 cup vegetable oil or melted butter, 1/3 cup brewed hot coffee, 1 tsp vanilla extract, and 1/4 tsp salt. Mix until just combined. Gently fold in 1/2 cup chocolate chips for an extra chocolatey brownie.
Bake the brownies: Pour the batter evenly over the layer of graham crackers in the prepared pan. Bake in the preheated oven for about 40 minutes or until a toothpick inserted in the center comes out with a few moist crumbs.
Add marshmallows: Pull the brownies out and carefully scatter 2 cups of mini marshmallows on top. Return to the oven and bake for an additional 3-4 minutes, just until the marshmallows puff up and become slightly golden.
Toast the marshmallows: If using a kitchen torch, carefully toast the marshmallows until golden brown. Alternatively, place the pan under the broiler, keeping a close eye to prevent burning – this should only take a few minutes.
Cool and slice: Allow the brownies to cool completely in the pan before lifting out and slicing. Follow the notes provided on how best to slice these delicious morsels.

Storing & Reheating

You can store your lazy girl s’mores brownies at room temperature for up to 3 days, covered tightly to keep them fresh. For longer storage, refrigerate them in an airtight container for about a week. If you’re looking to keep these treats for an even longer period, you can freeze them for up to 3 months. To reheat, warm them in the microwave for about 15-20 seconds, but be aware that the marshmallows might lose some of their fluffy texture. A quick toast under the broiler will refresh them beautifully!

Chef’s Helpful Tips

Don’t overmix: Stir until just combined to maintain that fudgy texture we all love; too much mixing can lead to tough brownies.
Measure your graham crackers carefully: Use a ruler if you need to, as uneven layers may affect the final result.
Cooling tip: Let the brownies cool completely before slicing; this helps reduce the mess and ensures clean cuts.
Flavor boost: For an extra punch, consider adding a pinch of cinnamon to the batter, or swap the chocolate chips for peanut butter chips.
Make-ahead option: Feel free to prepare the brownie mix a day in advance, cover, and bake the next day.

Indulging in these easy brownies is truly delightful. You’ve got a comforting treat that requires minimal effort yet delivers impressive results, perfect for any occasion. So whether it’s a weeknight sweet craving, a potluck dessert, or just a reason to gather around the family table, these brownies will not disappoint.

Recipe FAQs

Can I use a different brownie mix?

Absolutely! You can choose any box brownie mix you prefer, though I recommend going with the traditional chocolate flavor to complement the s’mores theme perfectly.

What if I don’t have a kitchen torch?

No problem! If you don’t have a kitchen torch, simply use your oven’s broiler. Just place the pan under the broiler for a minute or so, closely monitoring to avoid burning the marshmallows.

Can I make these brownies gluten-free?

Yes, you can easily adapt this recipe for gluten-free eaters. Look for a gluten-free brownie mix and make sure your graham crackers are gluten-free as well.

How should I slice these brownies?

To slice the brownies, use a sharp knife dipped in hot water. Wipe it clean between cuts to achieve neat, clean slices and avoid tearing the marshmallow layer.
