Matcha red bean cake is a delicious and unique dessert that combines the earthy flavor of matcha with the sweet and nutty taste of red bean paste. To make this cake, start by mixing together flour, sugar, baking powder, and matcha powder. In a separate bowl, whisk together eggs, milk, and vegetable oil. Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Fold in the red bean paste and pour the batter into a greased cake pan. Bake for 30-35 minutes, or until a toothpick inserted into the center of the cake comes out clean. Let the cake cool before slicing and serving. This cake is perfect for any occasion and is sure to impress your guests with its unique flavor and beautiful green color.
