Step 2: Whisk the Eggs and Sugar

1. In a large mixing bowl, beat the eggs and sugar using an electric mixer until pale and fluffy (about 3-4 minutes).
2. Add the vanilla extract and mix until incorporated.

Step 3: Add Wet Ingredients

1. Slowly pour in the vegetable oil and mix well.
2. Add the milk and continue mixing until fully combined.

Step 4: Combine Dry Ingredients

1. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
2. Gradually sift the dry ingredients into the wet mixture, folding gently with a spatula to avoid over-mixing.
3. If using lemon zest, fold it in at this stage.

Step 5: Bake

1. Pour the batter into the prepared cake pan.
2. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
3. Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.

Step 6: Final Touches

1. Once the cake is cool, dust with powdered sugar using a sifter.
2. Serve with whipped cream and fresh berries if desired.
