Ingredients You’ll Need

5 graham cracker sheets – These provide a crunchy foundation reminiscent of classic s’mores, offering a sweet contrast to the soft brownie layer. If you can’t find graham crackers, you can use digestive biscuits.
1 box of brownie mix for an 8×8 inch pan – This is the heart of the recipe, allowing for quick preparation without sacrificing flavor. Use your favorite brand for the best results.
2 egg yolks – They add richness and moisture to the brownies. You can substitute with a flax egg if you want to go egg-free.
1/2 cup vegetable oil or melted butter – This fat contributes to a fudgy texture. Both options work well, but melted butter will give a richer flavor.
1/3 cup brewed hot coffee – Coffee enhances the chocolate flavor, elevating the overall taste of the brownies without making them taste like coffee. If you prefer, you can use milk or water instead.
1 tsp vanilla extract – Vanilla adds sweetness and depth. Always opt for pure extract for the best flavor.
1/4 tsp salt – A touch of salt balances the sweetness and enhances the flavors.
1/2 cup chocolate chips – These will melt into pockets of gooey chocolate throughout the brownies. Choose semi-sweet or dark chocolate for a more intense chocolate flavor.
2 cups mini marshmallows – A fun addition for that iconic s’mores experience, adding sweetness and a chewy texture.

How to Make Easy Brownies with Box Mix

Preheat the Oven: Start by preheating your oven to 325°F (163°C) and lining the bottom of an 8×8 inch baking pan with parchment paper or aluminum foil. This will help with easy removal later.
Prepare the Graham Crackers: Lay the graham cracker sheets in a single layer in the prepared pan, breaking them if needed to cover the entire surface evenly.
Mix the Brownie Batter: In a large bowl, combine the brownie mix, 2 egg yolks, 1/3 cup hot brewed coffee, 1/2 cup of vegetable oil or melted butter, 1 tsp vanilla extract, and 1/4 tsp salt. Stir until well blended, then fold in the 1/2 cup of chocolate chips.
Bake the Brownies: Pour the brownie batter over the graham cracker layer in the pan and spread it evenly. Bake for 40 minutes, until the edges are firm but the center is still soft.
Add the Marshmallows: Carefully remove the brownies from the oven and sprinkle the 2 cups of mini marshmallows on top. Return the brownies to the oven and bake for another 3-4 minutes, just until the marshmallows begin to puff up.
Toast the Marshmallows: Once the marshmallows are puffy, remove the pan from the oven. Use a kitchen torch to toast the marshmallows until golden brown. If you don’t have a torch, place them under the broiler, watching closely until they turn golden, which should only take a few minutes.
Cool and Slice: Allow the brownies to cool down completely before slicing. For perfect slices, read the notes on how to cut through the sticky marshmallows.

Storing & Reheating

Store your brownies at room temperature in an airtight container for up to 3 days to maintain their chewy texture. If you want to keep them for longer, refrigerate them in a sealed container for up to a week. For longer storage, you can freeze the brownies in freezer-safe bags for up to 3 months. To reheat, pop them in the microwave for 10-15 seconds to enjoy their gooey goodness again, though keep in mind that the texture might change slightly after freezing.

Chef’s Helpful Tips

Avoid overmixing the batter, as this can lead to tough brownies.
Ensure all your ingredients, especially the eggs, are at room temperature for better blending.
For a more decadent treat, add some extra chocolate chips on top of the marshmallows before baking.
If the edges of the brownies are done but the center isn’t, cover them loosely with foil to prevent over-baking.
Play around with flavors by adding nuts, or swapping half the chocolate chips for peanut butter chips for a twist.

Lazy girl s’mores brownies truly embody the magic of comfort food, bringing joy and delight with every bite. The combination of rich chocolate, crunchy graham crackers, and gooey marshmallows is unbeatable. Plus, this recipe is so approachable that even novice bakers can impress their friends and family. Don’t hesitate to let your creativity shine—experiment with flavors, or even incorporate seasonal ingredients!

Recipe FAQs

Can I make these brownies without coffee?

Absolutely! If you’d rather skip the coffee, you can substitute it with an equal amount of milk or even water. It won’t affect the outcome, though the coffee does enhance the chocolate flavor beautifully.

What can I use instead of egg yolks?

If you’re looking for a vegan option, you can replace the egg yolks with flax eggs. To make a flax egg, mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water, and let it sit for a few minutes to thicken.

How can I achieve perfectly toasted marshmallows?

Using a kitchen torch gives a wonderfully controlled toasting experience, but if you don’t have one, keeping an eye on them under the broiler is key. Make sure to remove them as soon as they’re golden brown to prevent burning.

What’s the best way to cut these brownies?

For neat slices, allow the brownies to cool completely. Use a sharp knife dipped in hot water and wiped dry to cut through the marshmallows without sticking. This also helps achieve clean edges in each piece.
