This matcha red bean swirl cake is a beautiful and delicious dessert that is perfect for any occasion. Using a food processor makes the process of making the cake batter and swirl 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 milk until smooth. Pour half of the batter into a greased cake pan and swirl in red bean paste. Pour the remaining batter on top and swirl in more red bean paste. Bake for 30-35 minutes and enjoy!
