Fluffy Sponge Cake

Ingredients

  • 4 large eggs (room temperature)
  • 1 cup granulated sugar
  • 1 cup all-purpose flour (sifted)
  • 1/2 tsp baking powder
  • 1/4 cup milk (warm)
  • 1/4 cup vegetable oil
  • 1 tsp vanilla extract
  • 1/4 tsp salt

Instructions

  1. Preheat Oven:
    Preheat your oven to 170°C (340°F). Line an 8-inch (20 cm) round cake pan with parchment paper. Do not grease the sides (this helps the cake rise evenly).
  2. Separate Eggs:
    Carefully separate egg whites and yolks into two clean bowls.
  3. Beat Egg Whites:
    Using an electric mixer, beat the egg whites and salt on medium speed until foamy. Gradually add half the sugar (1/2 cup), a tablespoon at a time, and beat until stiff peaks form.
  4. Beat Egg Yolks:
    In a separate bowl, beat the egg yolks with the remaining sugar (1/2 cup) until pale and thick. Add vanilla extract, milk, and oil. Mix well.
  5. Combine Mixtures:
    Gently fold the egg yolk mixture into the beaten egg whites using a spatula. Be careful not to deflate the batter.
  6. Add Dry Ingredients:
    Sift flour and baking powder together. Gradually fold it into the egg mixture in batches until just combined.
  7. Pour and Bake:
    Pour the batter into the prepared pan. Tap the pan gently to release air bubbles. Bake for 30–35 minutes or until the top is golden and a toothpick inserted into the center comes out clean.
  8. Cool the Cake:
    Let the cake cool in the pan for 10 minutes, then turn it out onto a wire rack to cool completely.

Tip: For extra fluffiness, invert the cake while cooling to maintain its height.

Let me know if you’d like a flavored version (like chocolate or lemon)!
