Preheat the oven to 180 °.

Grease and flour lightly, or lined with parchment paper, a 24 cm diameter mold.

Sift flour and baking powder in a bowl.

In a bowl or in a planetary mixer, beat the eggs with the sugar whisk until the mixture is clear and frothy. Always with the whisk in action, add the oil, yogurt and lemon zest.

Add the sifted flour, a little at a time.

Pour everything into the pan and level.

Cook for 35/40 minutes or until the appetizer comes out completely dry.

Let cool in the mold for a few minutes before transferring it to a grate to cool completely.

Sprinkle with icing sugar or you can enjoy it with delicious caramel.
