Instructions

Prepare the matcha cake

  1. Preheat your oven to 350°F (180°C). Grease and flour two 8-inch (20cm) round cake pans.
  2. In a medium bowl, whisk together the flour, sugar, matcha powder, baking powder, and salt.

  5. Divide the batter evenly between the prepared pans and smooth the tops.
  6. Bake for 20-25 minutes or until a toothpick inserted into the center comes out clean.
  7. Allow the cakes to cool in the pans for 5 minutes, then transfer them to a wire rack to cool completely.

Prepare the white chocolate mousse

  1. In a double boiler or a heatproof bowl set over a pot of simmering water, melt the white chocolate chips.
  2. Remove from the heat and stir in the heavy cream and granulated sugar until well combined.
  3. Allow the mixture to cool to room temperature.

Assemble the cake

  1. Place one of the cooled matcha cakes on a serving plate or cake stand.
  2. Spread the white chocolate mousse over the top of the cake, leaving a 1-inch (2.5cm) border around the edges.
  3. Top with the second matcha cake and press gently to adhere.

Prepare the matcha buttercream
