🛒 Ingredients

15 servings

15
  • For the sponge:
  • 3 eggs
  • 2½ cups all-purpose flour
  • 2 cups granulated sugar
  • 4 tablespoons margarine, softened
  • 1 cup whole milk
  • 1 pinch of salt
  • 3 teaspoons baking powder
  • For the flan:
  • 3 eggs
  • 1 can (14 oz) sweetened condensed milk
  • 1¾ cups whole milk (same volume as the condensed milk can)
  • For the caramel:
  • ½ cup granulated sugar

Directions

  1. 1

    Preheat the oven to 355 °F (180 °C). Make the caramel: melt ½ cup sugar dry in the baking pan over medium heat until deep amber. Swirl to coat the bottom and sides, then set aside to cool.

  2. 2

    Using an electric mixer, beat the margarine, sugar, and 3 sponge eggs together for 5 minutes until pale and fluffy.

  3. 3

    Gradually add the flour and milk alternately, mix in the salt, and finally fold in the baking powder. Beat until completely smooth.

  4. 4

    Pour the sponge batter into the caramelized pan and spread it evenly.

  5. 5

    In a blender, combine the 3 flan eggs, condensed milk, and whole milk. Blend for 1 minute until perfectly smooth.

  6. 6

    Gently pour the flan mixture over the sponge batter — do not stir. The two layers will magically switch places during baking.

  7. 7

    Bake at 355 °F (180 °C) for 30–35 minutes, until a toothpick inserted into the sponge layer comes out clean.

  8. 8

    Let cool completely at room temperature, then refrigerate for at least 2 hours before unmolding onto a serving plate.

💡 Chef's Tip

Avoid stirring the caramel as it melts to prevent crystallization. It's perfectly normal if the two batters blend slightly when pouring — the oven handles the rest. Run a thin knife around the edges before flipping for a clean, caramel-dripping release.
