Matcha S’mores Brownies Recipe

Introduction

These Matcha S’mores Brownies combine the earthy flavor of matcha green tea with the classic gooey sweetness of marshmallows and a crunchy graham cracker crust. This unique twist on a beloved treat is perfect for those who enjoy bold flavors and a fun texture contrast.

A batch of square-shaped bars is arranged on a white marbled surface, each piece showing three clear layers: a rough, light brown bottom crust, a thick middle layer of green filling with a somewhat dense texture, and a top layer of cracked, swirled white meringue with light brown swirls. One bar is slightly lifted above the others, showing the layers side by side clearly. Crumbs are scattered around the squares. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

  • 13 (195 g) full graham cracker sheets (~2 sleeves)
  • 3 tablespoons (36 g) granulated sugar
  • 6 tablespoons (84 g) unsalted butter, melted and cooled
  • ¾ cup (93.75 g) all-purpose flour
  • ½ teaspoon (3 g) salt
  • ½ cup (113.5 g) unsalted butter
  • ½ cup (90 g) white chocolate chips
  • 1 cup (200 g) granulated sugar
  • 2 eggs (100 g)
  • 2 tablespoons (12 g) matcha powder, sifted
  • 1 tablespoon (13 g) vanilla paste or extract
  • 1 cup (127 g) marshmallow fluff

Instructions

  1. Step 1: Preheat your oven to 350°F (177°C). Line an 8-inch or 9-inch baking pan with parchment paper for easy removal and cleanup.
  2. Step 2: To make the graham cracker crust, place the graham cracker sheets and 3 tablespoons of sugar in a food processor. Blitz until fine crumbs form, about 10–20 seconds.
  3. Step 3: Add the melted and cooled 6 tablespoons of butter to the crumbs. Pulse until the mixture resembles slightly wet sand.
  4. Step 4: Transfer the crust mixture to the lined baking pan. Pack it tightly and evenly into the bottom using the flat bottom of a measuring cup or a silicone spatula. Set aside.
  5. Step 5: In a microwave-safe bowl, heat ½ cup unsalted butter and ½ cup white chocolate chips in 30-second intervals, stirring between, until melted and combined (about 1–3 minutes). Alternatively, melt using a double boiler.
  6. Step 6: In a large bowl, combine the melted butter and white chocolate mixture with 1 cup granulated sugar. Stir until fully combined, even if the mixture is thick or clumpy.
  7. Step 7: Mix in the eggs, sifted matcha powder, and vanilla paste or extract until smooth. For a crinkly brownie top, whisk vigorously until the batter lightens in color.
  8. Step 8: Gently fold in the flour and salt, mixing just until no dry spots remain. Pour the batter over the prepared graham cracker crust in the pan.
  9. Step 9: Spread 1 cup of marshmallow fluff on top of the batter. Optional: swirl the fluff lightly to create a marbled effect, keeping in mind that the marbling will brown during baking.
  10. Step 10: Bake for 45–55 minutes, or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Remove from the oven and transfer to a wire rack to cool.
  11. Step 11: Allow the brownies to cool completely for at least 1 hour before slicing. Enjoy your Matcha S’mores Brownies!

Tips & Variations

  • Use a kitchen scale to weigh ingredients for more consistent results, especially flour and matcha powder.
  • If you prefer a stronger matcha flavor, add an extra half tablespoon of sifted matcha powder.
  • For a nuttier crust, mix a handful of finely chopped nuts into the graham cracker crust before pressing it into the pan.
  • Swap marshmallow fluff for mini marshmallows if you prefer a more toasted top—add them in the last 10 minutes of baking to prevent burning.

Storage

Store these brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. To reheat, warm individual pieces in the microwave for 10–15 seconds to soften the marshmallow topping. These brownies can also be frozen for up to 2 months; thaw at room temperature before serving.

How to Serve

A group of square bars is placed on a white marbled surface, each bar showing two visible layers; the bottom layer is light brown with a crumbly texture resembling a cookie or crust, while the top layer is green with a moist, slightly grainy texture, covered by a thin, cracked off-white swirl pattern that looks like a baked meringue or topping. One of the bars is lifted and held by a woman's hand, revealing the two layers clearly in profile. The bars are neatly cut, and some crumbs are scattered around on the surface.

FAQs

Can I substitute matcha powder with regular green tea powder?

Matcha powder is finely ground green tea leaves with a vibrant flavor and color, so regular green tea powder will not provide the same intensity or texture. It’s best to use culinary-grade matcha powder for this recipe.

Can I use a different type of chocolate?

White chocolate chips are recommended for their sweetness and creaminess that balance the matcha. However, you can experiment with milk or semi-sweet chocolate for a different flavor, but the overall taste will change.

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.
