Ingredients

Scale
  • 1/2 cup (113g) unsalted butter, melted
  • 1 cup (200g) granulated sugar
  • 1/2 cup (100g) brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 3/4 cup (95g) all-purpose flour
  • 1/2 cup (50g) unsweetened cocoa powder
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder
  • 1 cup graham crackers, roughly crushed
  • 1 1/2 cups mini marshmallows
  • 1/2 cup milk chocolate chips (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease your 8-inch cast iron skillet with butter or nonstick spray.
  2. In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth and slightly glossy, about 2 minutes.
  3. Beat in eggs one at a time, then stir in vanilla extract until the batter is thick and creamy.
  4. In a separate bowl, sift together flour, cocoa powder, salt, and baking powder.
  5. Gradually fold the dry ingredients into the wet ingredients with a spatula until just combined; do not overmix.
  6. Pour the batter evenly into the prepared skillet, smoothing the top.
  7. Sprinkle crushed graham crackers and milk chocolate chips evenly over the batter.
  8. Bake for 20 minutes until edges start to pull away and center jiggles slightly.
  9. Remove skillet from oven and sprinkle mini marshmallows evenly on top.
  10. Return skillet to oven and bake for an additional 3-5 minutes until marshmallows are golden and toasted. Watch closely to avoid burning.
  11. Let the skillet cool for 5 minutes before serving to allow the brownie to set.

Notes

Do not overbake to keep brownies gooey. Use fresh mini marshmallows for best toasting results. A kitchen torch can be used to toast marshmallows for better control. For dairy-free, substitute butter with coconut oil and use vegan chocolate chips and marshmallows. For gluten-free, substitute flour with a gluten-free baking blend.
