Preheat the oven to 350ºF and grease and dust the bottom and sides of a 9 inch springform pan or cake pan with flour.
Zest 2 large lemons and extract the juice from them. Measure out the zest and juice and place them in a large bowl.
Mix in the granulated sugar, eggs, and oil and stir until well combined.
In the same bowl, mix in the all-purpose flour, baking powder, salt, and lastly the Greek Yogurt.
Stir until all ingredients are moistened.
Spoon the mixture evenly into the prepared cake pan or springform pan. The cake batter will be very thick.
Bake for 50-55 minutes in the preheated oven. Check the center of the cake with a toothpick to make sure the toothpick comes out clean before removing it from the oven.
Allow the cake to cool for about 20 minutes before removing the cake from the pan.
Cool completely before dusting the cake with powdered sugar.
Notes
Use a full quarter cup of lemon zest. The zest carries the lemon flavor.
Do not overmix. Stir until just combined. The batter will be very thick.
Grease and flour both the bottom and sides of the pan for easy release.
Cool at least 20 minutes before removing from the pan.
Dust with powdered sugar just before serving so it does not dissolve.
Store covered at room temperature for up to 3 days. Freezes well for up to 2 months.
