Ingredients

Scale
  • 1 cup graham cracker crumbs (100g)
  • 3 tablespoons unsalted butter, melted (42g)
  • 2 tablespoons granulated sugar (25g)
  • 1/2 cup unsalted butter, melted (115g)
  • 3/4 cup granulated sugar (150g)
  • 1/4 cup brown sugar (50g)
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1/2 cup all-purpose flour (60g) (can substitute almond flour for gluten-free)
  • 1/3 cup unsweetened cocoa powder (35g)
  • 1/4 teaspoon salt
  • 1/2 cup chocolate chips or chunks (90g)
  • 1 1/2 cups mini marshmallows (150g)

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. In a small bowl, combine graham cracker crumbs, melted unsalted butter, and granulated sugar. Mix well until crumbs are evenly coated.
  3. Press the crust mixture firmly into the bottom of an 8-inch cast-iron skillet, creating an even layer.
  4. In a medium bowl, whisk together melted unsalted butter, granulated sugar, and brown sugar until smooth.
  5. Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
  6. In a separate bowl, sift together all-purpose flour, unsweetened cocoa powder, and salt.
  7. Gradually fold the dry ingredients into the wet mixture until just combined.
  8. Fold in chocolate chips or chunks.
  9. Pour the batter over the graham cracker crust in the skillet and smooth the top with a spatula.
  10. Bake for 20 minutes until the brownie is nearly set but still soft in the center.
  11. Remove from oven and immediately sprinkle mini marshmallows evenly over the top.
  12. Return to the oven and bake for an additional 5-7 minutes until marshmallows are golden and toasted.
  13. Optional: Broil for 1-2 minutes for a deeper toast, watching carefully to prevent burning.
  14. Remove skillet from oven and let cool for 10 minutes.
  15. Serve warm, straight from the skillet with a scoop of vanilla ice cream or drizzle of chocolate sauce if desired.

Notes

Press the graham cracker crust firmly for best texture. Avoid overmixing the batter to keep it fudgy, not cakey. Add marshmallows near the end of baking to prevent burning. Use broil setting carefully for extra toasting. If using a different pan, crust may not be as crisp. For dairy-free, substitute butter with coconut oil and use vegan marshmallows.
