🛒 Ingredients

10 servings

10
  • 3 eggs, separated
  • 1 cup (125 g) all-purpose flour, sifted
  • ½ cup + 2 tbsp (125 g) granulated sugar
  • ½ cup (125 g) unsalted butter, softened
  • ½ tsp baking powder
  • Powdered sugar for dusting
  • 1 can (14 oz / 397 g) sweetened condensed milk

Directions

  1. 1

    Preheat your oven to 350 °F (180 °C). Grease and flour an 8-inch (20 cm) round springform pan.

  2. 2

    Beat the sugar, egg yolks, and softened butter with an electric mixer until pale, fluffy, and creamy.

  3. 3

    Gradually fold in the sifted flour until the batter is smooth and well combined.

  4. 4

    In a separate bowl, whisk the egg whites to stiff peaks, then gently fold them into the batter using a spatula, keeping it airy with upward strokes.

  5. 5

    Sprinkle in the baking powder and fold gently one last time to preserve the lightness.

  6. 6

    Pour the batter into the prepared pan and bake for 20–25 minutes, until a toothpick inserted in the center comes out clean. Allow to cool completely.

  7. 7

    Make the dulce de leche: place the unopened condensed milk can in a pot, cover with water, and boil for 40 minutes. Let it cool completely before opening.

  8. 8

    Slice the cooled cake horizontally in half. Spread the dulce de leche generously over the bottom layer, place the top back, and finish with a dusting of powdered sugar.

💡 Chef's Tip

For a richer, thicker dulce de leche, extend the cooking time to 45 minutes — always keep the can fully submerged in water. The cake keeps in the refrigerator for up to 3 days wrapped in plastic film.
