Ingredients

Main Ingredients

• 6 large eggs, separated
• 1 cup (120 g) cake flour
• ¾ cup (150 g) granulated sugar
• ¼ cup (60 ml) whole milk
• ¼ cup (60 ml) vegetable oil
• 1 teaspoon vanilla extract
• 1 teaspoon baking powder

Optional Additions

• 1 teaspoon lemon zest
• 1 teaspoon almond extract
• Powdered sugar for dusting
• Fresh strawberries, blueberries, or raspberries
• Whipped cream
• Fruit preserves or jam
• Chocolate drizzle

Tips for Success

• Use room-temperature eggs for better volume.
• Beat the egg whites until they form stiff, glossy peaks.
• Fold the egg whites gently into the batter to preserve the air.
• Sift the flour to avoid lumps.
• Do not overmix after adding the flour.
• Bake immediately after preparing the batter.
• Avoid opening the oven door during baking.
• Let the cake cool gradually to minimize shrinking.

Instructions

1. Preheat the oven to 325°F (160°C) and line a baking pan with parchment paper.
2. In a bowl, whisk together the egg yolks, milk, oil, and vanilla extract.
3. Sift in the cake flour, baking powder, and salt. Mix until smooth.
4. In a separate bowl, beat the egg whites with the cream of tartar until foamy.
5. Gradually add the sugar while beating until stiff peaks form.
6. Fold one-third of the egg whites into the yolk mixture to lighten it.
7. Gently fold in the remaining egg whites until fully combined.
8. Pour the batter into the prepared pan and smooth the top.
9. Bake for 40–50 minutes, or until a toothpick inserted into the center comes out clean.
