Black Sesame Cake with Green Tea Mousse



Baked the cake in a 9 inch spring form pan
After the cake cooled, I cut it in half
I assembled the cake in the spring form pan


The green tea mousse in this cake is delicious and nicely pairs with the black sesame cake.

My modifications:
  • I baked the cake in a spring form pan
  • I did not make the white sesame mousse, and just doubled the green tea mousse
  • When making the green tea mousse, 
  • I assembled the cake in a spring form pan, and did not wait 30 min in between putting the first layer of green tea mousse, and adding the 2nd layer of cake. I did however, put the cake in the fridge after putting on the second layer of green tea mouse before frosting the sides. 
Here's what I did:
Cake
  1. Preheat oven to 350 degrees.
  2. Greased 9 inch spring form pan, and put wax paper on bottom
  3. Combined flour, teaspoons baking powder, salt and set aside
  4. Ground 3 tablespoons of black sesame seeds. In a small bowl, combined 1 tablespoon of ground black sesame with 1 table spoon honey to make sesame paste. Added this sesame paste in small bowl with 2 tablespoons of ground black sesame in bowl, 1 egg at room temperature, and 1/2 teaspoon vanilla
  5. Beat together sugar and softened butter for ~ 3 min until light and fluffy. 
  6. Added the black sesame mixture on medium speed in 2 additions
  7. Added flour mixture in 3 additions and coconut milk in 2 additions, alternating starting with the flour mixture first and ending with the flour mixture. 
  8. Baked for 25 min
Green Tea Mousse
  1. Whisked together 8 large egg yolks with 2/3 cup granulated sugar and 1/4 teaspoon of salt
  2. Combine 4 tablespoons of coconut milk and 4 tablespoons of water. Then sprinkle 2 packets of 0.25 oz (0.5 oz total) of unflavored gelatin on top of coconut milk + water and let it bloom for 5 min. 
  3. Combine 2 tablespoons of water with 2 teaspoons of green tea in a different bowl and set aside. 
  4. Add 1 cup of coconut milk and 1.5 cups of heavy cream in a sauce pan and bring to simmer. 
  5. Remove from heat and add to yolk mixture in a steady stream, while constantly stirring to prevent curdling. 
  6. Put everything back in pan and cook on medium heat until mixture thickened and coats back of spoon; constantly stir. 
  7. Remove from heat and stir in gelatin until dissolved, then green tea powder and 2 teaspoons of vanilla. 
  8. Pour mixture through strainer.
  9. Let cool. I stored it in the fridge and finished the mouse the next morning. 
  10. Next morning, I whipped 2 cups of heavy whipping cream with 2 tablespoons of confectioner's sugar.
  11. I had to use the hand mixture to evenly combine the green tea gelatin with the whipped cream.  

Assembling Cake
  1. Slice black sesame cake in half. 
  2. Assemble the came in the spring form pan.
  3. Put first layer of cake down. Then add a layer of green tea mousse. Then add 2nd layer of cake. and finish with another layer of green tea mousse. Make sure a little mousse left to frost sides. 
  4. Put in fridge to set for 30 min. 
  5. Then take off sides of the spring form pan, and frost the sides with the green tea mousse. 
  6. Finish with decorating the cake. Similar to what the recipe suggested, I decorated with green tea powder, black sesame powder, raspberries, and black berries. 


MatchaGoma Mousse Cake (Green Tea-Black Sesame Mousse Cake)




yield: one 9-inch cake (I used a 9-inch spring form pan)

Black Sesame Cake


Ingredients
1-1/4 cups (6-1/4 ounces) unbleached all-purpose flour (used bleached all-purpose flour)
1-1/4 teaspoons baking powder
1/4 teaspoon fine sea salt
2 tablespoons black sesame seeds
2 tablespoons black sesame paste (combined 1 tablespoon of ground black sesame with 1 table spoon of honey)
1 large egg, room temperature
1/2 teaspoon pure vanilla extract
6 tablespoons (3 ounces) unsalted butter, softened (microwaved for 20 seconds)
3/4 cup (5-1/4 ounces) sugar
1/2 cup, plus 2 tablespoons canned unsweetened coconut milk




Directions
1. Adjust oven rack to middle position and heat oven to 350
. Grease one 8-inch round cake pan, line bottom with parchment, grease parchment round, dust cake pan with flour, and tap out excess. In a medium bowl, whisk flour, baking powder, and salt together, set aside.

2. Toast the sesame seeds in a dry pan over medium heat, stirring constantly, until they are fragrant, about two minutes. (Optional but brings out the sesame flavor) Grind, or pound the seeds in a spice grinder until they are the texture of damp sand. Combine grounded sesame sees, sesame paste, eggs and vanilla in a 1-cup measuring cup, stir to combine, set aside.

3. In the bowl of standing mixer, fitted with paddle attachment, beat butter and sugar on medium-low speed until sugar is moistened, about 30 seconds. Increase speed to medium-high and beat until mixture is light and fluffy, about 3 minutes. Reduce speed to medium, add sesame mixture in two additions, beat until combined.

4. Reduce speed to low, add dry ingredients in 3 additions, alternating with coconut milk (in 2 additions), beginning and ending with dry ingredients. Beat in each addition until barely combined. Remove bowl from mixer, stir batter by hand with rubber spatula to ensure there are no streaks of flour left on the bottom of the bowl. Divide batter evenly between prepared cake pans; spread batter to edges of pans with small off-set spatula and smooth surfaces.

5. Bake cakes until toothpick inserted into center of cakes comes out clean, about 25-35 minutes. Cool in pans 20 minutes, then invert cakes onto greased wire rack; peel off and discard paper rounds. Cool cakes to room temperature, about 1 hour. (Cooled cakes can be wrapped in plastic wrap and refrigerate for up to 1 day.)
