01 - Preheat the oven to 350°F. Grease and line a 9x5-inch loaf pan with parchment paper.
02 - In a large bowl, whisk together flour, baking powder, baking soda, and salt until well blended.
03 - In a separate bowl, combine Greek yogurt, granulated sugar, eggs, oil, lemon zest, lemon juice, and vanilla extract. Whisk until smooth and creamy.
04 - Pour the wet mixture into the dry ingredients. Gently fold with a spatula until just combined—avoid overmixing to keep the loaf tender.
05 - Transfer batter to the prepared pan and smooth the top. Bake for 45–55 minutes until a toothpick inserted into the center comes out clean.
06 - Let the loaf cool in the pan for 10 minutes, then remove to a wire rack. Once completely cooled, whisk powdered sugar with lemon juice to create a thick glaze and drizzle over the top.
07 - Slice into 10 even portions and serve at room temperature.
