Ingredients

Scale
  • 1 box brownie mix (1820 oz)
  • 1/4 cup vegetable oil
  • 2 tablespoons water
  • 1 large egg (room temperature)
  • 1/3 cup mini chocolate chips (optional)
  • 1/2 cup unsalted butter, softened
  • 1/3 cup brown sugar, packed
  • 1/4 cup granulated sugar
  • 2 tablespoons milk (dairy or plant-based)
  • 1 teaspoon pure vanilla extract
  • 1 cup all-purpose flour (heat-treated)
  • 1/2 cup mini chocolate chips
  • Pinch of salt
  • 1012 large marshmallows (cut in half or use marshmallow fluff)
  • 4 oz milk chocolate, chopped or Hershey bars

Instructions

  1. Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. In a large bowl, combine brownie mix, vegetable oil, water, and egg. Mix until just combined. Fold in mini chocolate chips if using.
  3. Scoop dough onto baking sheets using a medium cookie scoop or tablespoon, spacing 2 inches apart. Flatten slightly. Bake for 8-10 minutes, until edges are set but centers look slightly underdone.
  4. Transfer cookies to a wire rack and cool completely, at least 15 minutes.
  5. While cookies cool, cream together butter, brown sugar, and granulated sugar in a bowl. Add milk and vanilla; mix well. Stir in heat-treated flour and salt until just combined. Fold in mini chocolate chips.
  6. Set broiler to high. Place marshmallow halves on a parchment-lined baking sheet and broil for 30-60 seconds until golden brown, watching closely. Alternatively, use a kitchen torch.
  7. To assemble, spread a generous tablespoon of cookie dough on the flat side of one brownie cookie. Top with a toasted marshmallow and a piece of chocolate. Press a second brownie cookie on top to make a sandwich. Repeat with remaining cookies.
  8. Optional: Melt 2 oz chocolate in the microwave and drizzle over assembled cookies.
  9. Serve immediately for gooey marshmallow, or chill in the fridge for 15 minutes for firmer layers.

Notes

Chill cookie dough for 10 minutes if too soft before spreading. If brownie cookies spread too much, chill dough for 15 minutes before baking. Assemble marshmallow layer quickly for best results. For gluten-free, use gluten-free brownie mix and almond flour. Vegan substitutions work well for butter, milk, and marshmallows.
