Ingredients

Scale
  • 1 ½ cups graham cracker crumbs (honey-flavored preferred)
  • 6 tablespoons unsalted butter, melted
  • ¼ cup granulated sugar
  • Pinch of salt
  • ½ cup unsalted butter (1 stick), melted
  • 1 cup granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • ⅓ cup unsweetened cocoa powder (Dutch-processed optional)
  • ½ cup all-purpose flour (or gluten-free flour blend)
  • ¼ teaspoon baking powder
  • ¼ teaspoon salt
  • ½ cup semi-sweet chocolate chips
  • 2 cups mini marshmallows
  • Optional: sprinkle of crushed graham crackers for garnish

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×9-inch pan lightly with butter or non-stick spray.
  2. In a small bowl, combine graham cracker crumbs, melted butter, granulated sugar, and salt. Mix until crumbs are evenly coated and mixture holds together when pressed.
  3. Press the crust mixture firmly into the bottom of the prepared pan to create an even, compact layer.
  4. Bake the crust for 8 minutes. Remove from oven and let cool slightly.
  5. In a large bowl, whisk melted butter and granulated sugar until smooth. Add eggs one at a time, whisking well after each addition. Stir in vanilla extract.
  6. In a separate bowl, sift together cocoa powder, flour, baking powder, and salt.
  7. Gradually add dry ingredients to wet ingredients. Fold gently with a spatula until just combined.
  8. Fold in semi-sweet chocolate chips.
  9. Pour brownie batter evenly over the pre-baked graham cracker crust and smooth the top.
  10. Bake for 20 minutes.
  11. Remove pan and scatter mini marshmallows evenly over the top.
  12. Return to oven and bake an additional 8-10 minutes until marshmallows are golden and toasted. Watch closely to prevent burning.
  13. Remove from oven and let cool completely in the pan on a wire rack.
  14. Slice into squares and serve. Optionally sprinkle with crushed graham crackers.

Notes

Press the graham cracker crust firmly to avoid crumbling. Add marshmallows halfway through baking to keep them gooey and toasted. For a golden finish, broil marshmallows for 20-30 seconds but watch closely to prevent burning. Let brownies cool completely before slicing or chill for 30 minutes for cleaner cuts. Gluten-free and vegan adaptations are possible with ingredient swaps.
