Preheat oven to 180°C. Butter and flour a 23cm round cake pan.
02 -
In a large bowl, whisk together eggs, yogurt, oil, and vanilla extract until smooth and well incorporated.
03 -
Incorporate sugar into the wet mixture and blend thoroughly. If using lemon zest, fold it in now to release the aromatic oils.
04 -
In a separate bowl, whisk together flour, baking powder, and salt. Gradually add this dry mixture to the wet ingredients, folding gently until a smooth, homogeneous batter forms. Be careful not to overmix.
05 -
Pour the batter into the prepared pan, smoothing the top with a spatula. Tap the pan gently on the counter to release air bubbles. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
06 -
Allow the cake to cool in the pan for 10 minutes. Then carefully turn it out onto a cooling rack and let it cool completely.

Just before serving, dust the top with icing sugar to create the signature cloud-like appearance.
