Preheat your oven to 180°C (350°F). Grease and line an 8-inch (20 cm) round cake pan with parchment paper.
Step 2: Beat the Eggs and Sugar
In a large mixing bowl, beat the eggs and sugar together using a hand mixer or whisk until light, pale, and fluffy. This will take about 3-5 minutes.
Step 3: Add the Greek Yogurt and Lemon Zest
Gently fold in the Greek yogurt and lemon zest using a spatula or whisk until well combined.
Step 4: Add Dry Ingredients
In a separate bowl, whisk together the cornstarch and pinch of salt. Gradually sift the dry ingredients into the wet mixture, folding gently to avoid deflating the batter.
Step 5: Bake the Cake
Pour the batter into the prepared cake pan and smooth the top.
