  • 3/4 cup graham cracker crumbs
  • 1 tablespoon sugar
  • 4 tablespoons melted unsalted butter
  • Pinch of salt optional


  • 3 ounces unsweetened chocolate
  • 1/2 cup unsalted butter 4 ounces
  • 2 large eggs
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking powder
  • 2/3 cup all purpose flour
  • 2 cups approximately marshmallows


  • Preheat the oven to 350 degrees F. Line an 8 inch square metal pan with nonstick foil.
  • Crust: Mix the graham cracker crumbs with the sugar, melted butter and salt (if using). Press into bottom of pan and bake for 6 minutes.
  • Brownies: Melt the chocolate and butter together in the microwave, a double boiler or heavy saucepan set over low heat. Let cool for about 5 minutes.
  • Whisk the eggs and sugar and vanilla together in a mixing bowl.
  • Stir the slightly cooled chocolate mixture into the egg mixture, then stir in the salt and baking powder. Add flour and stir until well blended.
  • Pour the brownie mixture over the graham crust, then return to oven and bake for 22-26 minutes or until set.
  • Remove from oven and sprinkle marshmallows over top in one generous layer.
  • Adjust oven rack so that brownies are about 6 inches from broiler element, then set brownies under broiler (set on high) for 1 minute or until golden. Keep a close eye, because marshmallows brown quickly!
  • Let cool on a rack. When cool, chill. Lift from pan and cut into squares. For a cleaner cut, freeze before slicing.
