Start by preheating your oven to 350°F (175°C). This ensures your loaf bakes evenly and rises beautifully.
Lightly grease your loaf pan with coconut oil or line it with parchment paper for easy removal later on.
In a mixing bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside.
In another bowl, combine the Greek yogurt, sugar, eggs, lemon zest, vanilla extract, and melted coconut oil. Mix until smooth and well combined.
Gradually add the dry mixture to the wet mixture, stirring gently until just combined. Be careful not to overmix, as this can lead to a dense loaf.
Pour the batter into the prepared loaf pan, smoothing the top with a spatula.
Bake in the preheated oven for about 50-60 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden brown and slightly domed.
Once baked, remove from the oven and let the loaf cool in the pan for about 10 minutes before transferring it to a cooling rack to cool completely.
In a small bowl, whisk together the powdered sugar and fresh lemon juice until smooth. Drizzle over the cooled loaf for a sweet, tangy finish.
