Smores Brownie Mix Cookies (Printable Version)

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

# List of Ingredients:

→ 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)

# Directions:

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 with no dry streaks remaining.
03 - Gently fold in the chocolate chips and crushed graham crackers until evenly distributed.
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 finish, 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 require almost no skill because brownie mix does the heavy lifting, leaving you to focus on the fun part: watching marshmallows bubble and brown.
  • The combination of soft, chewy cookie base with gooey marshmallow on top creates a texture contrast that somehow tastes even better than actual campfire s'mores.
  • You can make a batch in under 30 minutes, which means you can satisfy a craving or impress someone without spending your whole afternoon in the kitchen.
02 -
  • The marshmallow needs to go on while the cookie is still hot from the oven or it won't stick properly and will just slide off when you try to plate them.
  • Broiling is optional but transforms them—however, marshmallows burn faster than you'd think, so if this is your first time, skip broiling and enjoy the soft, melted version instead.
03 -
  • For deeper chocolate flavor, use a dark chocolate brownie mix or swap half the semi-sweet chocolate chips for dark chocolate ones, which creates a less sweet, more sophisticated cookie.
  • A tiny pinch of cinnamon stirred into the dry mix adds unexpected warmth and makes the whole thing taste more like campfire s'mores and less like a dessert.
