This airy Japanese cheesecake is soft, fluffy, and delicately sweet with a melt-in-your-mouth texture. Perfect for a delightful dessert or tea-time treat. Preheat oven to 320°F (160°C). Line and grease a 7-inch round cake pan, and prepare a hot water bath. In a bowl, melt together cream cheese, milk, and butter until smooth. Whisk in egg yolks, then gently fold in flour and cornstarch. In a separate bowl, beat egg whites with cream of tartar, gradually adding sugar until soft peaks form. Gently fold into the batter. Pour batter into the pan, place in the water bath, and bake for 50-60 minutes, or until set. Cool, dust with powdered sugar, and enjoy! #JapaneseCheesecake #FluffyDessert
