This matcha red bean pound cake is a dense and flavorful dessert that is perfect for tea time. Using a food processor makes the process of making the cake batter much easier. The cake is made with a combination of all-purpose flour, matcha powder, baking powder, and salt. In the food processor, mix together the dry ingredients with sugar, eggs, vegetable oil, and red bean paste until smooth. Pour the batter into a greased loaf pan and bake for 50-60 minutes. Let the cake cool before slicing and serving.
