This matcha mochi cake is a delicious and unique dessert that is sure to impress your guests. The cake is made with sweet rice flour, which gives it a chewy texture, and matcha powder, which gives it a beautiful green color and a subtle green tea flavor. To make the cake, simply mix together sweet rice flour, sugar, baking powder, and matcha powder. Then, add in eggs, milk, and oil, and mix until smooth. Pour the batter into a greased cake pan and bake for 30-35 minutes. Once the cake is done, let it cool and then cut into small squares to serve.
