Ingredients

  • 5 graham crackers
  • 85 g (3 oz) semisweet chocolate
  • 150 g (¾ cup) neutral oil
  • 200 g (1 cup) granulated sugar
  • 142 g ( cup) brown sugar
  • ½ teaspoon salt
  • 3 eggs, room temp
  • 2 teaspoon vanilla extract
  • 120 g (1 cup) all-purpose flour
  • 84 g (1 cup) dutch process cocoa powder
  • 140 g (5 oz) milk chocolate, for mixing in batter
  • 36 Large marshmallows

Instructions

  • Preheat the oven to 350 degrees F and line an 8" square pan with parchment paper.
  • Arrange the graham crackers in the pan. Set aside.
  • In a small bowl, add the semisweet chocolate and oil. Heat in the microwave in 30 second increments until fully melted. Set aside.
  • In a large bowl, add the sugars, salt, eggs, and vanilla. Using an electric hand mixer, beat on high speed for about 5-6 minutes until the mixture has doubled in size.
  • While mixing on low speed, slowly pour the chocolate, oil mixture into the sugar, egg mixture.
  • Next, add the flour and cocoa powder, and mix on low speed until mostly combined.
  • Lastly, fold in the milk chocolate until evenly dispersed.
  • Pour the brownie batter over the graham crackers in the prepared pan.
  • Bake the brownies for about 35 minutes. Allow to cool completely in the pan, about 1 hour.
  • Once cool, arrange the marshmallows on top. Bake for 5-8 minutes until the marshmallows are puffy and evenly golden brown.
  • Remove the brownies from the pan, then cut into 9 squares and enjoy!

Notes

  • Beat the sugars & eggs for a full 5-6 minutes! This is what will give the brownies that gorgeous shiny top, as well as a soft texture. 
  • Wait until the brownies to add the marshmallows. The marshmallows may melt and lose their shape if added to the brownies immediately once they come out of the oven. To prevent this, allow the brownies to cool completely, then add the marshmallows and toast.
