Preheat your oven to 180°C (356°F).

In a large mixing bowl, beat the eggs and sugar together until light and fluffy.

Add the lemon juice, lemon zest, vegetable oil, and milk to the egg mixture. Mix well.

In a separate bowl, combine the baking powder with the flour.

Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Butter and flour a 25-centimeter (10-inch) baking pan to prevent sticking.

Pour the batter into the prepared pan and smooth the top.

Bake in the preheated oven for 30 minutes, or until a toothpick inserted into the center comes out clean.

Allow the cake to cool in the pan for a few minutes before transferring to a wire rack to cool completely.
