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.
03 - In a separate bowl, mix Greek yogurt, granulated sugar, eggs, oil, lemon zest, lemon juice, and vanilla until smooth.
04 - Add the wet ingredients to the dry ingredients and gently fold until just combined. Do not overmix.
05 - Pour the batter into the prepared loaf pan and smooth the top evenly.
06 - Bake for 45-55 minutes or until a toothpick inserted into the center comes out clean.
07 - Cool in the pan for 10 minutes, then remove to a wire rack to cool completely.
08 - Whisk powdered sugar with enough lemon juice to make a thick but pourable glaze.
09 - Drizzle the glaze over the cooled loaf, slice, and serve.
