This cake evolves into its most delicious and soft state as each day passes. Follow these steps to create the perfect Condensed Milk Castella Cake:

  1. Begin by separating 12 egg whites from the yolks.
  2. In a large mixing bowl, combine 12 egg yolks, 50g sugar, 1 teaspoon salt, and 70g starch syrup. Beat until the mixture turns pale white, then reduce the speed and beat for an additional minute to remove air bubbles.
  3. In another bowl, whip 12 egg whites with 200g sugar until a soft peak meringue is formed.
  4. Combine the egg yolk mixture with the meringue using a spatula until well combined.
  5. Sift in 290g soft flour and 55g cornstarch, folding gently to moisten the batter without overmixing.
  6. Mix 70ml milk, 60ml oil, and 10ml vanilla extract. Add a portion of the batter to this mix, then fold it back into the main batter until incorporated.
  7. Prepare a baking tin lined with parchment paper. Pour in the batter and remove trapped air with a skewer.
  8. Bake in a preheated 190°C oven, then adjust the temperature to 170°C after 15 minutes, 160°C after another 15 minutes, and finally 150°C for the remaining 30 minutes. The total baking time should be 60 minutes.
  9. Once baked, invert the cake onto a greased silicon sheet, remove the parchment paper, and let it cool for at least an hour before serving. For the best flavor, enjoy it after a day.
  10. Cut the edges and slice the cake into desired shapes. Serve with tea or milk and savor the deliciousness.

Top 4 Mistakes and How to Avoid Them

Mistake 1: Overmixing the Batter

Overmixing can lead to a dense texture. Gently fold the flour and other ingredients only until moistened to maintain the cake’s lightness.

Mistake 2: Incorrect Meringue Texture

Ensure the egg whites form a soft peak meringue. This is crucial for the cake’s softness. Avoid undermixing or overbeating the meringue.

Mistake 3: Inadequate Cooling Time

Rushing the cooling process can affect the cake’s texture. Allow it to cool for at least an hour before serving, and for optimal taste, wait until the next day.

Mistake 4: Inaccurate Baking Temperature

Follow the specified baking temperatures to achieve the golden brown top and the perfect texture. Rapid temperature changes can impact the outcome.
