Smores Brownie Mix Cookies (Printable Version)

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

# What You'll Need:

→ 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
08 - 1/4 cup mini chocolate chips (optional, for garnish)
09 - 1/4 cup 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 brownie mix, eggs, vegetable oil, and water. Mix until just combined with no dry streaks remaining.
03 - Gently fold semi-sweet chocolate chips and crushed graham crackers into the batter.
04 - Scoop heaping tablespoons of dough onto prepared baking sheets, spacing cookies approximately 2 inches apart to yield 18 cookies.
05 - Bake for 8–9 minutes until cookies are set but retain a soft center.
06 - Remove from oven and immediately press one large marshmallow onto the center of each cookie.
07 - Return cookies to oven for 1–2 minutes until marshmallows are puffed and beginning to melt.
08 - Broil for 30 seconds, monitoring closely, until marshmallows achieve golden brown coloration.
09 - Remove cookies from oven. Immediately sprinkle mini chocolate chips and extra graham cracker crumbs if using. Cool on baking sheets for 5 minutes, then transfer to wire rack for complete cooling.

# Expert Tips:

01 -
  • They're ready in 25 minutes flat, which means you can satisfy a chocolate craving without the full commitment of scratch baking.
  • Graham crackers and marshmallows folded right into brownie dough create that s'mores magic without needing to leave your kitchen or build a fire.
  • The marshmallow topping gets all puffy and golden, which is genuinely fun to watch and even more fun to eat.
02 -
  • Timing the marshmallow toast is crucial—30 seconds under the broiler makes them golden, but 45 seconds turns them black and bitter, so stay in the kitchen and watch like a hawk.
  • Pressing the marshmallow in while the cookie is still hot is essential because the residual heat melts them enough to stick, but adding them cold means they'll just slide off mid-bake.
03 -
  • Keep your oven light on while broiling the marshmallows so you can watch them turn golden without opening the door and losing heat.
  • If your marshmallows are looking too golden too fast, move the baking sheet to a lower rack before finishing under the broiler—it gives you more control over the color.
