Preheat oven to 350°F/180°C/Gas 4. Lightly spray an 8-inch springform baking pan with cooking spray and set it aside.

Place the eggs and sugar into a large mixing bowl and whisk until well combined. Add lemon zest, orange zest, lemon juice, orange juice, Greek yogurt, olive oil, and vanilla extract. Continue to whisk until the mixture is smooth.

Add the flour, baking powder, and salt to the bowl. Gently fold the dry ingredients into the batter using a spatula, taking care not to overmix.

Pour the batter into the prepared cake pan and bake for 25-30 minutes or until a cocktail stick inserted into the center of the cake comes out clean. Begin to check the cake at 25 minutes to avoid over-baking.

Leave the cake to cool for 10 minutes in the pan, carefully remove it and place it on a wire rack. Allow it to cool to room temperature before slicing.

Serve with some fresh or frozen berries of choice. Enjoy!
