01 - Preheat oven to 350°F. Line a standard 12-cup muffin tin with paper liners or lightly grease each cup.
02 - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, salt, finely grated fresh ginger, and lemon zest until well combined.
03 - In a separate bowl, whisk the eggs, vegetable oil, Greek yogurt or buttermilk, lemon juice, and vanilla extract until mixture is smooth.
04 - Pour the wet mixture into the bowl with the dry ingredients and stir gently until just combined. Avoid overmixing for optimal texture.
05 - Divide the batter evenly among the muffin cups, filling each about three-quarters full for best rise.
06 - Bake for 16 to 18 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
07 - Allow muffins to cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
08 - For the glaze, whisk powdered sugar with 2 to 3 tablespoons lemon juice and grated ginger (if using) until smooth and pourable.
09 - Drizzle glaze over the completely cooled muffins. Let the glaze set before serving.
