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 flour, sugar, baking powder, baking soda, salt, grated ginger, and lemon zest until evenly blended.
03 - In a separate bowl, whisk together eggs, vegetable oil, Greek yogurt, lemon juice, and vanilla extract until smooth.
04 - Pour wet ingredients into the dry mixture. Stir gently until just combined, being careful not to overmix.
05 - Divide the batter evenly into the prepared muffin cups, filling each about three-quarters full.
06 - Transfer muffin tin to the oven and bake for 16–18 minutes, or until a toothpick inserted into the center comes out clean.
07 - Allow muffins to cool in the tin for 5 minutes, then remove to a wire rack to cool completely.
08 - In a small bowl, blend together powdered sugar, lemon juice, and optional grated ginger until smooth and pourable.
09 - Drizzle glaze over cooled muffins. Let the glaze set before serving.
