01 - Preheat oven to 350°F. Line a standard 12-cup muffin tin with paper liners or lightly coat with nonstick spray.
02 - In a large mixing bowl, whisk together all-purpose flour, granulated sugar, baking powder, baking soda, salt, grated ginger, and lemon zest until well blended.
03 - In a separate bowl, whisk eggs, vegetable oil, Greek yogurt, lemon juice, and vanilla extract until the mixture is smooth and homogenous.
04 - Add wet ingredients to the dry mixture. Stir gently until just incorporated; do not overmix to ensure a tender crumb.
05 - Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full. Place tray in the center of the oven.
06 - Bake for 16 to 18 minutes, or until a toothpick inserted into the center emerges clean with a few moist crumbs.
07 - Allow muffins to cool in the tin for 5 minutes before transferring to a wire rack to cool completely.
08 - Whisk together powdered sugar, lemon juice, and grated ginger (if using) in a small bowl until the glaze is smooth and pourable.
09 - Drizzle the glaze generously over cooled muffins. Let set before serving.
