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 mixing bowl.
03 - In a separate bowl, combine Greek yogurt, granulated sugar, eggs, oil, lemon zest, lemon juice, and vanilla extract. Whisk until smooth and well blended.
04 - Pour wet mixture into dry ingredients. Gently fold with a spatula until just combined. Do not overmix—small lumps are acceptable.
05 - Transfer batter to prepared loaf pan. Use a spatula to spread evenly and smooth the top surface.
06 - Bake for 45-55 minutes until golden brown and a toothpick inserted into the center emerges clean.
07 - Let loaf rest in pan for 10 minutes. Remove carefully and transfer to a wire rack to cool completely before glazing.
08 - Whisk powdered sugar with fresh lemon juice, adding juice gradually until reaching a thick, pourable consistency.
09 - Drizzle glaze over the completely cooled loaf. Allow glaze to set for 5 minutes before slicing into 10 servings.
