Ingredients

Scale
  • 1 standard 18.3 oz (520 g) box fudgy brownie mix
  • 2 large eggs, room temperature
  • 1/3 cup (80 ml) vegetable oil
  • 1/4 cup (60 ml) water
  • 1 cup (100 g) graham crackers, roughly crushed
  • 1 1/2 cups (about 150 g) mini marshmallows
  • 1/2 cup (90 g) semi-sweet chocolate chips (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
  2. In a mixing bowl, combine the brownie mix, 2 large eggs, 1/3 cup vegetable oil, and 1/4 cup water. Stir gently until just combined.
  3. Fold in 1 cup crushed graham crackers and 1/2 cup chocolate chips if using, mixing gently to distribute evenly.
  4. Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheet about 2 inches apart, each about 1.5 tablespoons of batter.
  5. Bake for 12-14 minutes until edges are set but centers remain soft with a slight sheen.
  6. Immediately after removing from the oven, gently press 3-4 mini marshmallows on top of each cookie.
  7. Toast the marshmallows using a kitchen torch until golden brown and slightly puffed (20-30 seconds), or place under a broiler on low for 1-2 minutes, watching closely.
  8. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a cooling rack to finish cooling.

Notes

If you don’t have a kitchen torch, use the oven broiler on low for 1-2 minutes, watching closely to avoid burning. Do not overmix the batter to keep cookies fudgy. Use room temperature eggs for better batter consistency. Crush graham crackers by hand for a chunky texture. Toast marshmallows immediately after baking while cookies are hot for best melting. Store dough in fridge up to 24 hours before baking. Cookies keep 2-3 days at room temperature or freeze up to 3 months.
