Tools You’ll Need

Step-by-Step Instructions
Step 1: Prepare the Crust
Preheat your oven to 350°F (177°C).
Line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy removal.
In a bowl, combine the graham cracker crumbs, melted butter, and granulated sugar.
Press the mixture evenly into the bottom of the prepared pan.
Bake for 8-10 minutes until slightly golden. Set aside.
Step 2: Make the Brownie Batter
In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth.
Add the eggs and vanilla extract, whisking until fully incorporated.
In another bowl, sift together the flour, cocoa powder, salt, and baking powder.
Gradually fold the dry ingredients into the wet mixture until just combined—do not overmix.
Step 3: Assemble and Bake
Pour the brownie batter over the pre-baked graham cracker crust.
Spread evenly with a spatula.
Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Step 4: Add the Toppings
Remove the brownies from the oven and immediately sprinkle the mini marshmallows and chocolate chips over the top.
Return to the oven and bake for an additional 5-7 minutes, just until the marshmallows are golden and toasty.
Watch closely to prevent burning.
Step 5: Cool and Serve
Allow the brownies to cool completely in the pan.
Use the parchment paper to lift them out and place them on a cutting board.
Garnish with extra graham cracker pieces if desired.
Slice into squares and enjoy!

Tips for Perfect S’mores Brownies
Use Parchment Paper – It makes removing and slicing the brownies much easier.
Don’t Overbake – You want fudgy brownies, not dry ones.
Toast Marshmallows Carefully – Keep an eye on them when broiling; they can burn quickly.
Cool Completely – This helps the brownies set properly and makes cutting cleaner.
Customize the Chocolate – Use semi-sweet or dark chocolate chips if you prefer.
Serving Suggestions
Vanilla Ice Cream – A scoop on top makes it even more indulgent.
Hot Cocoa – Perfect pairing for a cozy treat.
Fresh Berries – Strawberries or raspberries add a refreshing contrast.
Whipped Cream – A light and fluffy topping option.
Glass of Milk – Classic and perfect for balancing the rich chocolate flavors.
