Made from a boxed brownie mix, these S'more Brownie Cookies are filled with marshmallows, chocolate chips, and crushed graham crackers. If you love s'mores, these chewy chocolatey cookies are for you!
Line a baking sheet with parchment paper. Set aside.
In a large bowl, stir the brownie mix, eggs, butter, chocolate chips, marshmallows, and graham crackers together until combined.
Tightly cover the bowl of cookie dough and refrigerate for 30 minutes. While the dough is chilling, preheat oven to 350°F.
Once the dough is chilled, scoop a heaping tablespoon worth of brownie dough onto a baking sheet. Repeat to have 6 cookies on a medium baking sheet or up to 12 on a large sheet, leaving at least 2 inches between each cookie.
Bake for 11-12 minutes, or until the edges are set.
Allow cookies to cool on the sheet pan for 5 minutes, then transfer to a cooling rack to cool completely. Repeat with remaining cookie dough.
