Classic Red Bean Taiyaki is a beloved Japanese dessert that consists of a fish-shaped cake filled with sweet red bean paste. The batter for the taiyaki is made with flour, sugar, baking powder, and water, which is then poured into a fish-shaped mold. The mold is then filled with a generous amount of red bean paste and cooked until golden brown. The result is a crispy, golden exterior with a warm and gooey red bean filling. This traditional taiyaki recipe is perfect for those who enjoy the combination of sweet and savory flavors. Serve it warm for a delightful treat that will surely satisfy your sweet tooth.
