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 all-purpose flour, granulated sugar, baking powder, baking soda, salt, finely grated ginger, and lemon zest until thoroughly blended.
03 - In a separate bowl, whisk together eggs, vegetable oil, Greek yogurt or buttermilk, freshly squeezed lemon juice, and vanilla extract until the mixture is smooth and cohesive.
04 - Pour wet ingredients into the dry mixture. Stir gently just until combined and no dry streaks remain. Do not overmix to avoid toughness.
05 - Divide the batter evenly among the prepared muffin cups, filling each approximately three-quarters full.
06 - Bake in the preheated oven 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 tin for 5 minutes before transferring to a wire rack to cool completely.
08 - In a small bowl, whisk together powdered sugar, lemon juice, and grated ginger (if desired) until smooth and pourable.
09 - Drizzle or spoon the glaze over cooled muffins. Let glaze set before serving.
