Instructions:
First, beat the egg whites until stiff peaks form, then set aside. Next, in a mixer or using a whisk, beat the egg yolks, sugar, and margarine until the mixture becomes pale and fluffy.
Then, add the milk and sifted flour. After that, gently fold in the beaten egg whites and baking powder to maintain the batter’s lightness.
Grease a glass baking dish and pour in the batter. Bake in a preheated oven at 356 °F (180 °C) for approximately 35 minutes.
Meanwhile, prepare a mixture of milk and sweetened condensed milk. Always use more sweetened condensed milk than regular milk to achieve a creamier texture. Mix well and set aside.
