Bon Appetit Matcha Chocolate Cake

 






Ingredients

Makes one 8”-, or 9” diameter cake (used a 9” cake pan)

6 Tbsp. unsalted butter, melted, slightly cooled, plus room-temperature butter for pan

1½ cups (227 g) mochiko (sweet rice flour; such as Koda Farms or Bob’s Red Mill Sweet White Rice Flour)

1 tsp. baking powder

½ tsp. Diamond Crystal or ¼ tsp. Morton kosher salt

2 Tbsp. matcha, sifted, plus more for serving

2 large eggs

1 14-oz. can sweetened condensed milk

1 tsp. vanilla extract

1⅓ cups heavy cream, divided

4 oz. bittersweet chocolate, chopped

 

Preparation

Step 1

Place a rack in middle of oven; preheat to 350°. Generously butter an 8"- or 9"-diameter cake pan. Whisk mochiko, baking powder, salt, and 2 Tbsp. matcha in a large bowl just to combine. Vigorously whisk eggs and melted butter in a medium bowl until pale and emulsified, about 30 seconds. Add sweetened condensed milk, vanilla, and 1 cup cream and whisk until mixture is smooth. Scrape into dry ingredients and whisk vigorously until smooth and very thick. Scrape batter into prepared pan and smooth surface.

Step 2

Bake cake until it starts to pull away from sides of pan, top and edges are golden, and a tester inserted into the center comes out clean, 35–45 minutes (cake in the smaller pan will take longer to bake than one in the larger pan). Transfer pan to a wire rack and let cake cool 5 minutes. Turn cake out onto rack; let cool completely. Baked 40 min; was still undercooked at 35 min.

Step 3

Place chocolate in a small heatproof bowl. Bring remaining ⅓ cup cream to a boil in a small saucepan. Immediately pour over chocolate; let sit 15 seconds. Stir until ganache is smooth.

Step 4

Evenly pour ganache over top of cake. Using a small offset spatula or spoon, spread ganache to edges of cake (drips down the sides are encouraged!). Let sit until ganache is set, about 2 hours. (If you are in a hurry, you can chill cake until glaze is set, about 30 minutes.)

Step 5

Just before serving, dust top of cake with more matcha with a fine-mesh sieve.

Do ahead: Cake and glaze can be made 2 days ahead. Store cake tightly wrapped in several layers of plastic at room temperature. Let glaze cool, then chill in an airtight container. Gently reheat glaze in the microwave or a double boiler over a pan of simmering water (do not let bowl touch water) until just melted before using.
