In a mixing bowl, whisk together the Greek yogurt, sugar, eggs, and oil until no lumps remain.
Add the lemon extract and lemon zest and whisk again.
Add the flour, baking powder, and salt, and stir until combined. Transfer the batter to the prepared loaf pan and bake for 55-65 minutes, or until of the loaf is done and a toothpick inserted in the middle comes out mostly clean.
Allow the loaf to cool completely before removing from the pan and glazing.
Make the glaze by whisking together the glaze ingredients in a mixing bowl. Add an additional 1 tsp water if the glaze is too thick to slowly pour over the lemon loaf.
Drizzle the lemon glaze over the cooled loaf and allow the glaze to set for at least 15 minutes before slicing and serving!
