A simple, lightly sweetened and tender cake that's terrific with fresh fruit and whipped cream. Make it a day ahead, if desired, since it holds up well overnight.
Preheat oven to 350 degrees F. Generously grease a 9-inch round springform pan (or standard cake pan). Lightly coat with flour. Tap out excess flour.
In a large bowl beat the eggs and sugar until pale and billowy, about 2 minutes on high with an electric mixe. Add the yogurt, olive oil, lemon juice, and lemon zest and beat until smooth and blended, another 30 seconds.
Pour into the prepared cake pan and bake just until the top doesn’t make a dent when gently pressed and a toothpick comes out clean when inserted in the center, 40 to 45 minutes.
Let cool for about 20 minutes before releasing the spring form pan (if using a standard cake pan, run a knife along the edge, invert the cake, and set it right-side-up).
Lightly dust the top of the cake with powdered sugar. Cut into slices and serve with berries and optional cream/yogurt
Whip 1 cup heavy cream with a few tablespoons sugar. Gently fold in 1 cup plain Greek yogurt. Chill until ready to serve.
