Ingredients

Scale

Graham Cracker Crust

  • 13 full graham cracker sheets (195 g, about 2 sleeves)
  • 3 tablespoons (36 g) granulated sugar
  • 6 tablespoons (84 g) unsalted butter, melted and cooled

Dry Ingredients

  • ¾ cup (93.75 g) all-purpose flour
  • ½ teaspoon (3 g) salt

Wet Ingredients

  • ½ cup (113.5 g) unsalted butter
  • ½ cup (90 g) white chocolate chips
  • 1 cup (200 g) granulated sugar
  • 2 large eggs (100 g total)
  • 2 tablespoons (12 g) matcha powder, sifted
  • 1 tablespoon (13 g) vanilla paste or extract

Marshmallow Topping

  • 1 cup (127 g) marshmallow fluff

Instructions

  1. Prepare the Graham Cracker Crust: Line an 8-inch or 9-inch baking pan with parchment paper to ensure easy removal and cleanup. In a food processor, pulse 13 full graham cracker sheets with 3 tablespoons of granulated sugar until fine crumbs form, about 10-20 seconds. Add 6 tablespoons of melted and cooled unsalted butter, then pulse until the mixture resembles slightly wet sand. Transfer this mixture to the lined pan and press it tightly into the bottom using the flat bottom of a measuring cup to compact it evenly, then smooth the edges with a silicone spatula. Set aside.
  2. Make the Matcha Brownie Batter: Preheat your oven to 350°F (177°C). In a medium microwave-safe bowl, melt ½ cup unsalted butter and ½ cup white chocolate chips in 30-second intervals, stirring after each, until fully melted and combined, about 1-3 minutes total. Alternatively, use a double boiler. In a large mixing bowl, combine the melted butter and white chocolate mixture with 1 cup granulated sugar, stirring until incorporated. The mixture may appear thick and clumpy due to the white chocolate, but this is normal. Add 2 eggs, 2 tablespoons sifted matcha powder, and 1 tablespoon vanilla paste or extract, mixing until smooth. Whisk vigorously if you desire a crinkly top and lighter batter. Gently fold in ¾ cup all-purpose flour and ½ teaspoon salt until no dry streaks remain. Pour the batter over the graham cracker crust in the baking pan.
  3. Add the Marshmallow Topping: Spread 1 cup marshmallow fluff evenly over the brownie batter. Optionally, swirl the fluff into the batter with a spatula or knife to create a marbled effect. Be aware that this swirl will brown during baking and not retain a green color.
  4. Bake: Place the pan in the preheated oven and bake for 45-55 minutes, or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Remove from oven and transfer the pan to a wire rack to cool. Let the brownies cool completely for at least 1 hour before slicing to ensure the layers set properly.
  5. Serve and Enjoy: Once cooled, slice into squares and enjoy the rich matcha flavor combined with the sweet s’mores elements of graham cracker crust and marshmallow topping.

Notes

  • For best accuracy, weigh your ingredients rather than measuring by volume to ensure consistent results.
  • Spoon flour gently into your measuring cup and level it with a knife rather than scooping to avoid packing it tightly, which can change texture.
  • If you want a more distinct swirl effect in the marshmallow topping, avoid fully blending it into the batter.
  • The marshmallow topping will brown in the oven, which adds a toasty flavor reminiscent of traditional s’mores.
