This video shows a simple recipe for a Christmas wreath cake that can be made by simply mixing and piping. The brownie batter is made by melting butter, chocolate, and brown sugar in the microwave, emulsifying with eggs, and then mixing in sifted cake flour. Pour the batter into a chiffon cake pan, top with walnuts and cashews, and bake in the oven. For the matcha cream, dissolve matcha powder and granulated sugar in warm heavy cream, then whip together with the remaining cold heavy cream. Once the brownies have cooled, remove them from the pan, pipe the matcha cream in a wreath shape, and decorate with powdered sugar, strawberries, and Christmas decorations to complete a beautiful cake. The bitterness of the matcha and the moist texture of the brownies are a perfect combination, and you can also enjoy the texture of the nuts.
