White Chocolate Green Tea Brownies

These brownies are made with white chocolate that caramelizes slightly in the brownie. The swirl of green tea is slightly herbal and bitter, balancing with the sweet butterscotch tones of the brownie. The brownie bar itself has a lovely chew and bite, like a soft dense cookie that will have you swoon with love. Pair with a Japanese craft beer or with a glass of green tea or coffee.

Ingredients

  • 1 2/3 cups chopped white chocolate 10 ounces or 285 g (see note below about quality)
  • 3/4 cup unsalted butter at room temperature 1 1/2 sticks, 6 ounces or 170 g
  • 3/4 cup granulated white sugar 150 g
  • 3/4 cup packed dark brown sugar 165 g
  • 2 teaspoon vanilla extract
  • 1 teaspoon baking powder
  • 3/4 teaspoon kosher salt
  • 3 large eggs
  • 1/2 cup extra virgin olive oil
  • 2 1/4 cup all-purpose flour 315 g
  • 1 tablespoon matcha green tea powder (see note below about quality)

Instructions

  1. Preheat the oven to 350°F. Lightly spray a 9 x 13-inch baking pan with cooking oil, then line with parchment paper, making sure 1-inch of paper hangs over the edges
    Spray baking pan with cooking oil, then line with parchment paper.
  2. Melt the white chocolate in a microwave, cooking on high for 30 second increments, stirring thoroughly with a fork between intervals. Alternatively you can melt the chocolate in a double boiler (a metal bowl over a simmer pot of water).

    Melt white chocolate in microwave or double boiler.
  3. Place the butter, both sugars, vanilla, baking powder and salt in the bowl of a stand mixer fitted with the paddle attachment. Beat on low speed until the mixture starts to look like a paste, then increase to medium speed until the mixture starts to cling to the side of the bowl about 2 minutes.
    place butter, both sugar, vanilla, baking powder and salt in the bowl of stand mixer with a paddle attachment and cream until a paste clings to the side of the bowl.
  4. Add the eggs, one at a time, beating each into the mixture first, then scraping down the sides of the bowl before adding the next egg.
    add the eggs one at a time.
  5. Add the olive oil to the mixture and beat to incorporate. Add the melted white chocolate and mix until the mixture thickens and start to look a bit like frosting. At this point some of the chocolate might solidify back into tiny chunks. Don’t worry about that. Add the flour and mix. Once all the flour has been absorbed into the batter, scrape down the sides of the bowl to make sure everything is incorporated, mixing a little more if necessary.
    Add the oil, white chocolate and flour, individually, mixing thoroughly before adding the next addition.
  6. Spoon all but 1/2 cup of the batter into the prepared baking pan. Spread evenly across the pan. Mix the matcha green tea powder into the remaining 1/2 cup of batter.
    Spoon most of the batter into the pan, leaving 1/2 cup left. Then mix the matcha green tea powder into the remaining batter.
  7. Drop small heaping teaspoons of green tea batter over the batter then swirl with a knife or chopstick decoratively. Don’t overmix.
    drop the green tea batter all over the top, then swirl with a chopstick or knife.
  8. Bake in the oven for 23 to 25 minutes long, or until the edges of the brownie pan start to look golden brown. Let cool completely in the pan before lifting the entire brownies sheet out of the pan with the overhanging parchment paper and moving it to a cutting board. Peel away the paper and cut into squares.

Recipe Notes

Matcha is a powdered green tea that you can get at Japanese or Asian grocery stores, well stocked grocery stores (look in the tea section) or online. Don’t bother getting the higher quality matcha, you can usually find culinary grade matcha at a lower price point.

When selecting white chocolate, I usually recommend looking at the ingredient list for the bar or bag and making sure that one of the first ingredients is cocoa butter. If it’s vegetable oil, its subpar white chocolate and you’ll be able to tell with the end product.
