Ingredients You’ll Need

5 graham cracker sheets: These provide that classic s’mores crunch. Feel free to use honey or chocolate-flavored graham crackers for an extra layer of flavor!
1 box of brownie mix for an 8×8 inch pan: The base of this recipe. Choose your favorite brand for the best results.
2 egg yolks: These add richness and moisture to the brownie batter.
1/2 cup vegetable oil or melted butter: Choose butter for a richer flavor or keep it light with vegetable oil.
1/3 cup brewed hot coffee: Enhances the chocolate flavor of the brownies, making them even more decadent.
1 tsp vanilla extract: A must-have to provide that warm, comforting aroma.
1/4 tsp salt: This amplifies the sweetness and balances the flavors.
1/2 cup chocolate chips: Because, more chocolate is always better!
2 cups mini marshmallows: These add that signature s’mores topping. You can substitute with large marshmallows if that’s what you have on hand.

How to Make Easy Brownies with Box Mix

Preheat the Oven: Start by preheating your oven to 325°F. Line an 8×8 inch baking pan with parchment paper or aluminum foil, leaving an overhang on the sides. This will make removing the brownies a simple task later on.
Prepare the Cracker Layer: Place the graham cracker sheets at the bottom of the pan in a single layer, ensuring you cover the entire surface. If needed, break some sheets to fit them neatly.
Mix Your Brownie Batter: In a large bowl, combine the brownie mix, 2 egg yolks, 1/3 cup of brewed hot coffee, 1/2 cup of vegetable oil or melted butter, 1 tsp vanilla extract, and 1/4 tsp salt. Blend until smooth and consistent. Gently fold in the 1/2 cup of chocolate chips for an extra chocolatey punch.
Add the Brownie Batter: Pour the rich brownie batter evenly over the layer of graham crackers in the prepared pan. Bake in the preheated oven for about 40 minutes. The edges should look firm, and a toothpick inserted in the center will come out with some moist crumbs.
Top with Mini Marshmallows: Carefully pull the pan from the oven and immediately sprinkle the 2 cups of mini marshmallows on top of the brownies. Place the pan back in the oven and bake for an additional 3-4 minutes. You want the marshmallows to puff up and slightly toast.
Toast the Marshmallows: Once you’ve removed the pan from the oven, use a kitchen torch to toast the marshmallows until golden. If you don’t have a torch, don’t worry! You can place the pan under the broiler for a few minutes—just keep a watchful eye to avoid burning.
Cool and Slice: Allow the brownies to cool completely in the pan before attempting to slice them. For easy lifting, hold the overhang of the parchment or foil. Cutting easier with a sharp knife dipped in hot water can help achieve clean cuts.
Serving Suggestion: You can enjoy them warm, but letting them sit for a while lets the flavors deepen. Store leftovers (if there are any!) in an airtight container.

Storing & Reheating

To store your brownies, let them cool completely and then place them in an airtight container at room temperature for up to four days. For longer storage, keep them in the refrigerator for up to a week, or freeze them for up to 3 months. When reheating, pop them in the microwave for about 15-20 seconds. They may lose a bit of texture, but a little warmth can refresh that gooey goodness!

Chef’s Helpful Tips

Avoid overmixing your brownie batter, which can lead to tough brownies. Mix until just combined.
For extra richness, consider adding a tablespoon of sour cream to your batter.
If your marshmallows aren’t browning quickly, make sure your oven is well-preheated and keep a close eye to prevent burning!
Experiment by adding nuts or different types of chocolate to the batter for a personal touch.
Plan ahead: you can make the brownie base a day before serving, just add the marshmallows and toast when ready.

These brownies are sure to be the star of any dessert table. They are simple, visually appealing, and a joy to share with family or friends. Plus, everyone loves a good chocolate treat!

Recipe FAQs

Can I use homemade brownie batter instead of a box mix?

Absolutely! If you have a favorite homemade brownie recipe, feel free to use that instead of store-bought mix. Just ensure the quantities are adjusted for an 8×8 inch pan.

How do I know when the brownies are done baking?

After baking for 40 minutes, check the edges for a firm appearance and insert a toothpick in the center. It should come out with a few moist crumbs, indicating that the brownies are done but still fudgy.

Can I freeze these brownies?

Yes, these brownies freeze beautifully! Wrap individual pieces in plastic wrap and then place them in an airtight container to keep them fresh for up to 3 months.

What if I don’t have graham crackers?

If you’re out of graham crackers, you can use crushed digestive biscuits or any other crispy cookie as a substitute. It may change the flavor slightly but will still be delicious!
