Ingredients

Scale
  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 3/4 cup (90g) all-purpose flour (or almond flour for gluten-free)
  • 1/3 cup (35g) unsweetened cocoa powder (preferably Dutch-processed)
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 cup crushed graham crackers (gluten-free crackers optional)
  • 1 1/2 cups mini marshmallows
  • 1 cup chocolate chips (semi-sweet or milk chocolate)

Instructions

  1. Preheat your oven to 350°F (175°C). Warm the 10-inch cast iron skillet on the stove over low heat for 1-2 minutes.
  2. Lightly grease the skillet with butter or non-stick spray. Sprinkle half of the crushed graham crackers evenly on the bottom.
  3. In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth and glossy. Add eggs one at a time, mixing well after each. Stir in vanilla extract.
  4. In a separate bowl, sift together flour, cocoa powder, baking powder, and salt.
  5. Gradually fold dry ingredients into wet ingredients gently until just combined; do not overmix.
  6. Fold in chocolate chips.
  7. Pour half the batter over the graham cracker base in the skillet. Sprinkle remaining crushed graham crackers on top, then dollop the rest of the batter over and spread gently.
  8. Scatter mini marshmallows evenly over the top.
  9. Bake for 25-30 minutes until marshmallows are toasted golden and edges pull slightly from skillet sides; center should jiggle slightly. Tent with foil if marshmallows brown too quickly.
  10. Cool in skillet for at least 15 minutes before serving warm.

Notes

Preheat the skillet slightly to ensure even baking and prevent soggy bottoms. If marshmallows brown too fast, tent with foil halfway through baking. Let brownies cool at least 15 minutes before serving to set the gooey center. For firmer brownies, cool completely and rewarm servings before eating. Use quality Dutch-processed cocoa powder for best flavor. Variations include adding nuts, salted caramel drizzle, or using gluten-free/vegan substitutions.
