Preheat oven to 350 degrees F and spray 8x8 square baking dish, 9x5 loaf pan, 8-9 inch cake pan or bundt cake pan with cooking spray. Set aside.
In a large bowl, add eggs and sugar. Beat with an electric mixer until light color and fluffy, about 3 minutes. Add Greek yogurt and beat just to incorporate.
Add baking soda and flour in 1/4 cup portions and beat just until cake batter forms. Pour into prepared pan and bake: for 35 minutes in a square dish or round cake pan, for 30 minutes in bundt pan, 40-45 minutes in loaf pan, or until toothpick inserted in the center comes out clean. Times are guidelines, play it by ear. Don't overbake.
Remove from the oven, let stand for 10-15 minutes and slice into 9 pieces using sharp knife (serrated knife ruins it). Enjoy!
