🛒 Ingredients

10 servings

10
  • 1 cup (225 g) unsalted butter, softened
  • 2 cups (400 g) granulated sugar
  • 3 large eggs, yolks and whites separated
  • 1 cup (240 ml) whole milk
  • 3 cups (375 g) all-purpose flour, sifted
  • 2 teaspoons baking powder
  • Pinch of salt
  • Butter and flour to grease the pan

Directions

  1. 1

    Preheat your oven to 350 °F (180 °C). Grease and flour a 9-inch (24 cm) round cake pan.

  2. 2

    In a stand mixer, beat the softened butter and sugar together on medium speed for 4–5 minutes until pale and fluffy.

  3. 3

    Add the egg yolks one at a time, beating well after each addition.

  4. 4

    Pour in the milk in a steady stream while mixing on low speed until fully combined.

  5. 5

    Gradually add the sifted flour and baking powder, mixing until just incorporated — do not overmix.

  6. 6

    In a clean bowl, beat the egg whites with a pinch of salt to stiff peaks.

  7. 7

    Gently fold the egg whites into the batter in three additions using a rubber spatula, using sweeping motions to keep as much air as possible.

  8. 8

    Pour the batter into the prepared pan and smooth the top. Bake for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean.

  9. 9

    Cool in the pan for 10 minutes, then turn out onto a wire rack. Decorate once fully cooled.

💡 Chef's Tip

Room-temperature ingredients are key — cold butter or milk can cause the batter to curdle. If the cake top browns too quickly, loosely tent it with foil after the first 25 minutes.
