Preheat your oven to 350Β°F (175Β°C) and lightly grease a 9x13-inch baking dish or line it with parchment paper.
In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Mix until evenly combined.
Press the graham cracker mixture firmly into the bottom of the prepared baking dish to form an even crust.
Follow the instructions on the brownie mix box to prepare the batter. Typically, this involves combining the brownie mix, eggs, vegetable oil, and water in a bowl until fully incorporated.
Pour the brownie batter over the graham cracker crust and spread evenly with a spatula.
Bake in the preheated oven for 25β30 minutes, or until a toothpick inserted into the center comes out with moist crumbs. Remove the baking dish from the oven.
Sprinkle the chopped milk chocolate and mini marshmallows evenly over the top of the baked brownies.
Return the dish to the oven and bake for an additional 5β7 minutes, or until the marshmallows are golden brown and slightly toasted. Keep a close eye on them to prevent over-toasting.
Remove the S'mores Brownie Bars from the oven and let them cool completely in the baking dish to allow the layers to set.
Once cooled, slice into 12 bars and serve. Store any leftovers in an airtight container at room temperature for up to 3 days.
