This video shows a recipe for a firm custard pudding cake that can be made with just five ingredients. First, make a caramel sauce with water and granulated sugar and pour it into a heat-resistant container. Next, warm the milk and vanilla extract and add it to a mixture of egg yolks and granulated sugar to make the pudding mixture. Make a meringue with egg whites and granulated sugar and mix it with the cake flour into the egg yolk mixture. Pour this into the mold containing the caramel sauce and bake it in the oven using a water bath. Once the cake is baked, chill it thoroughly in the refrigerator, remove it from the mold and slice it to complete a beautiful two-layered pudding cake. The moist and smooth pudding and fluffy sponge cake create an exquisite harmony. It's a perfect treat for your home cafe or for entertaining guests.
