01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or coat lightly with nonstick spray.
02 - In a large bowl, whisk together flour, granulated sugar, baking powder, baking soda, salt, grated ginger, and lemon zest until well mixed.
03 - In a separate bowl, whisk eggs, vegetable oil, Greek yogurt, lemon juice, and vanilla extract until smooth and homogeneous.
04 - Pour wet mixture into the bowl of dry ingredients. Stir gently until just combined. Avoid overmixing for best texture.
05 - Distribute batter evenly among prepared muffin cups, filling each about three-quarters full.
06 - Bake muffins for 16 to 18 minutes, or until a toothpick inserted in the center emerges clean.
07 - Let muffins rest in the pan for 5 minutes. Transfer to a wire rack to cool completely before glazing.
08 - In a small bowl, mix powdered sugar with 2 to 3 tablespoons lemon juice and grated ginger (if using) until smooth and pourable.
09 - Drizzle glaze over completely cooled muffins. Allow glaze to set before serving.
