Smores Brownie Mix Cookies (Printable)

Chewy brownie-style cookies with chocolate, graham crackers, and a toasted marshmallow topping.

# Components:

→ For the Cookies

01 - 1 box (18–20 oz) brownie mix
02 - 2 large eggs
03 - 1/3 cup vegetable oil
04 - 1 tablespoon water
05 - 1/2 cup semi-sweet chocolate chips
06 - 1/2 cup crushed graham crackers (approximately 4 sheets)

→ For the Marshmallow Top

07 - 18 large marshmallows (one per cookie)
08 - 1/4 cup mini chocolate chips (optional, for garnish)
09 - 1/4 cup additional crushed graham crackers (optional, for garnish)

# Method:

01 - Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper.
02 - In a large bowl, combine the brownie mix, eggs, oil, and water. Mix until just combined and no dry streaks remain.
03 - Gently fold in the chocolate chips and crushed graham crackers.
04 - Scoop heaping tablespoons of dough onto the prepared baking sheets, spacing approximately 2 inches apart to yield about 18 cookies.
05 - Bake for 8–9 minutes, until cookies are just set but still soft in the center.
06 - Remove from oven and immediately press one large marshmallow onto the center of each cookie.
07 - Return cookies to the oven for 1–2 minutes, until marshmallows are puffed and just starting to melt.
08 - For a toasted top, broil for 30 seconds, watching closely, until marshmallows turn golden brown.
09 - Remove cookies from oven. Immediately sprinkle with mini chocolate chips and extra graham cracker crumbs, if using. Cool on baking sheets for 5 minutes, then transfer to a wire rack to cool completely.

# Expert Advice:

01 -
  • They taste like s'mores but you don't need a campfire or a coat, just your regular oven and maybe 30 minutes of your time.
  • The brownie mix does the heavy lifting so you can focus on the fun part—watching marshmallows puff up and turn golden.
02 -
  • Don't skip the 5-minute cooling period on the baking sheet—the cookies need that time to firm up enough to move without falling apart, which I learned the hard way with marshmallow-covered fingers and regret.
  • The marshmallow has to go in while the cookie is hot, or it won't melt properly and you'll just have a cookie with a marshmallow sitting on top like an afterthought.
03 -
  • Don't let anyone tell you that you need fancy ingredients—a box of brownie mix and marshmallows in your pantry are basically an open invitation to make something people will remember.
  • If your marshmallows start sliding off, press them in more firmly or prop them up with a few chocolate chips as little supports, which is a totally normal thing to do and not cheating.
