This matcha pound cake is a classic dessert with a twist. The cake is made with butter, sugar, eggs, flour, and matcha powder, which gives it a beautiful green color and a subtle green tea flavor. To make the cake, simply cream together butter and sugar, and then add in eggs one at a time. Mix in flour and matcha powder, and then pour the batter into a greased loaf pan. Bake for 50-60 minutes, and then let the cake cool before slicing and serving.
