Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line it with parchment paper for easy removal.
Mix Dry Ingredients: In a large mixing bowl, whisk together the flour, sugar, baking powder, and a pinch of salt until well combined.
Combine Wet Ingredients: In another bowl, whisk together the yogurt, oil, eggs, lemon juice, and lemon zest until smooth and creamy.
Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring gently until just combined. Be careful not to overmix; a few lumps are perfectly fine!
Pour Batter into Pan: Pour the batter into the prepared cake pan, smoothing the top with a spatula.
Bake: Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center of the cake comes out clean. The top should be lightly golden and spring back when touched.
Cool: Once baked, remove the cake from the oven and allow it to cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely.
Serve: This cake can be enjoyed plain, but for an extra touch, consider topping it with a simple lemon glaze made from powdered sugar and lemon juice, or serve it with fresh whipped cream or fruit.
