This matcha sponge cake is a light and airy dessert that's perfect for any occasion. The cake is made with flour, sugar, eggs, and matcha powder, which gives it a beautiful green color and a slightly bitter, earthy flavor. The cake is baked in a preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean. The result is a delicate and fluffy cake that's perfect for serving with tea or coffee. To make the cake, you'll need a mixer, a large bowl, and some patience, as the cake must be baked and cooled before serving.
