This recipe uses a rice cooker to make a fluffy soufflé cheesecake. Mix room-temperature cream cheese with milk and egg yolks, then add sifted cake flour to make a smooth batter. In a separate bowl, whisk egg whites and granulated sugar with a hand mixer to make a meringue, then gently fold it into the batter. Mix in orange peel and chocolate chips, then pour the batter into the buttered inner pot of a rice cooker and bake using the regular rice cooking setting. Once baked, let it cool slightly, then chill in the refrigerator for a moist and rich flavor. Sprinkle with cocoa powder to taste for an easy and delicious dessert.
