These matcha red bean muffins are a delicious and easy breakfast or snack option. Using a food processor makes the process of making the muffin batter much easier. The muffins are 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 muffin tin and bake for 20-25 minutes. Let the muffins cool before serving.
