This matcha marble cake is a beautiful and delicious dessert that's perfect for any occasion. The cake is made with flour, sugar, eggs, butter, baking powder, salt, and matcha powder. Half of the batter is mixed with matcha powder to create a beautiful green color and a slightly bitter, earthy flavor, while the other half is left plain. The two batters are then swirled together to create a beautiful marble effect. The cake is moist and fluffy, with a delicate crumb that melts in your mouth. It'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 in a preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely before serving.
