This creamy yogurt cake is the perfect balance of tangy yogurt and a soft, velvety texture. It's an easy-to-make dessert that's both refreshing and indulgent. Preheat your oven to 180°C (350°F) and grease a 9-inch round cake pan. In a large bowl, whisk the eggs and sugar together until light and fluffy. Add in the yogurt, vegetable oil, vanilla extract, and lemon juice (if using), and mix until smooth. Sift the flour, baking powder, and salt together, then gently fold them into the wet ingredients until fully combined.
