01 - Preheat oven to 350°F. Grease a 9x5-inch loaf pan and line with parchment paper.
02 - Whisk together flour, baking powder, baking soda, and salt in a large bowl until thoroughly 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, being careful not to overmix.
05 - Pour the batter into the prepared loaf pan and smooth the top with a spatula for even baking.
06 - Bake for 45-55 minutes until a toothpick inserted into the center comes out clean.
07 - Let the loaf cool in the pan for 10 minutes, then carefully remove to a wire rack to cool completely.
08 - Whisk powdered sugar with enough lemon juice to achieve a thick but pourable consistency.
09 - Drizzle the glaze over the completely cooled loaf. Slice into pieces and serve.
