These matcha red bean brownies are a delicious and unique twist on a classic dessert. Using a food processor makes the process of making the brownie batter much easier. The brownies are made with a combination of all-purpose flour, matcha powder, cocoa 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 baking dish and bake for 25-30 minutes. Let the brownies cool before slicing and serving.
