Grease a 9"x9" baking pan with olive oil. In a large bowl combine the sugar, eggs, yogurt, vanilla, and olive oil. Whisk until pale and well combined. In a separate bowl, whisk the dry ingredients together and add to the wet ingredients.
Pour into the prepared pan and bake for 25-30 minutes in the center of the oven until golden brown, or until a toothpick inserted into the center comes out clean.
Cool for 15 minutes in the pan, and invert on to a rack and cool fully before serving.
