This recipe is a mini version of the classic matcha red bean cake, perfect for individual servings. To make this cake, you will need flour, sugar, eggs, butter, matcha powder, and red bean paste. First, cream the butter and sugar together until light and fluffy. Add the eggs one at a time, mixing well after each addition. Sift in the flour and matcha powder and mix until just combined. Pour the batter into greased muffin tins and add spoonfuls of red bean paste on top. Bake in the oven for 20-25 minutes at 350°F. Once done, let it cool and enjoy!
