Here’s a recipe for a Castella Cake using condensed milk:
Ingredients:
- 3 large eggs
- 1 cup granulated sugar
- 1 tsp vanilla extract
- 1 cup all-purpose flour
- 1/2 tsp baking powder
- 1/2 cup condensed milk
- 1/4 cup warm water

Instructions:
- Preheat oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan.
- In a large mixing bowl, whisk the eggs until light and frothy.
- Add the sugar and vanilla extract to the eggs and whisk until well combined.
- Sift in the flour and baking powder and gently fold into the egg mixture until just combined.
- In a separate bowl, combine the condensed milk and warm water.
- Slowly pour the condensed milk mixture into the batter, whisking continuously until well combined.
- Pour the batter into the prepared loaf pan.
- Tap the pan gently on the counter to release any air bubbles.
- Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted in the center comes out clean.
- Remove from the oven and let the cake cool in the pan for 10 minutes before removing and letting it cool completely on a wire rack.
- Once cooled, slice and serve. Enjoy!
