In a large bowl, combine the yogurt, sugar, and eggs - stirring until well blended.
Bake for 30-40 minutes or until the cake feels springy to the touch and a toothpick inserted into the center comes out clean (every oven is different, so check with the toothpick test rather than the time). Be careful not to overbake though.
