Preheat your oven to 180°C (350°F). Grease and flour a round or rectangular cake pan (approximately 20 cm or 8 inches) to ensure the cake comes out easily.
Mix the Dry Ingredients:
In a mixing bowl, combine 12 tablespoons of all-purpose flour and 12 tablespoons of granulated sugar. If using lemon zest, add it to the dry ingredients for extra flavor.
Combine Wet Ingredients:
In another bowl, whisk together the 3 eggs, 12 tablespoons of milk, and 12 tablespoons of vegetable oil until well combined. If using lemon juice, add it at this stage for an added tang.
Combine and Mix:
Gradually add the wet ingredients to the dry ingredients, stirring gently until just combined. Avoid overmixing to keep the cake light and fluffy.
Step 2: Bake the Cake
Pour the Batter:
Pour the batter into the prepared cake pan, smoothing the top with a spatula for an even surface.
