01 - Preheat oven to 350°F. Line a standard 12-cup muffin tin with paper liners or lightly grease each cavity.
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, fresh lemon juice, and vanilla extract until smooth and homogenous.
04 - Add the wet mixture to the dry ingredients and gently mix until just combined, taking care not to overmix the batter.
05 - Divide the batter evenly among the muffin cups, filling each about three-quarters full for even rising.
06 - Bake for 16 to 18 minutes, or until a toothpick inserted into the center of a muffin emerges clean.
07 - Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely before glazing.
08 - For the glaze, whisk powdered sugar, lemon juice, and grated ginger (if using) in a small bowl until smooth and pourable. Drizzle glaze generously over cooled muffins and allow to set before serving.
