Ingredients

• 1½ cups all-purpose flour
• ½ cup vegetable oil
• ¾ cup milk (room temperature)
• 1½ cups sugar
• 3 large eggs (room temperature)
• 1 teaspoon vanilla extract
• Zest of 1 lemon
• Pinch of salt
• 1 teaspoon baking powder
• 1 tablespoon cocoa powder (unsweetened)
• 3 tablespoons milk (extra for chocolate batter)

Instructions

1. Preheat oven to 180°C (350°F). Grease and flour a standard cake pan.
2. In a large bowl, beat the eggs with lemon zest, salt, and vanilla until well combined. Gradually add sugar and continue beating until the mixture is light and creamy.
3. Add vegetable oil, then milk, mixing well after each addition.
4. Sift in the flour and baking powder. Gently fold until just combined — do not overmix.
5. Pour ¾ of the batter into the prepared pan.
6. To the remaining batter, add cocoa powder and 3 tablespoons milk. Mix until smooth.
7. Drop the chocolate batter randomly over the vanilla batter. Use a knife or skewer to gently swirl for a beautiful marble effect.
8. Bake for 40-45 minutes or until a toothpick inserted in the center comes out clean.
9. Let the cake cool in the pan for 10 minutes, then transfer to a wire rack. Decorate with chocolate ganache, pistachios, or powdered sugar as desired.

Tips for Success

• Bring all ingredients to room temperature for better volume and texture.
• Do not overmix the batter after adding flour to keep the cake soft.
• For a more intense chocolate flavor, add ½ teaspoon instant coffee to the chocolate batter.
• This cake stays moist for 3-4 days when stored in an airtight container.
• You can bake it in a bundt pan for a more elegant presentation.
