First, preheat oven to 350°F.
In bowl whisk the eggs and salt.
Add in the sugar, vanilla extract and whisk more.
Add yogurt then the oil and whisk well for a minute or two.
Add the sifted all purpose flour and baking powder.
Mix well with a wooden spoon.
Pour the batter in a slightly greased pan (with oil). I have used a 9 inch round pan in this recipe.
Bake for about 40 to 50 minutes or until a knife inserted in the center of cake comes out clean. You may need to place under the broiler in the last 5 minutes of baking.
Let cool for 5 minutes.
Dust with powdered sugar (optional).
