Heat oven to 375°F. Line a 12-cup muffin tin with liners or lightly grease.
Whisk flour, sugar, baking powder, baking soda, and salt in a large bowl. Stir in poppy seeds.
Whisk eggs, yogurt, milk, melted butter, vanilla, lemon zest, and lemon juice in a separate bowl.
Pour the wet mixture into the dry ingredients. Fold gently until just combined; a few small lumps are fine.
Divide batter evenly among muffin cups, filling each about three-quarters full.
Bake until tops are set and lightly golden, 16 to 18 minutes. A toothpick should come out clean.
Cool in the pan for 5 minutes, then transfer muffins to a rack to finish cooling.
Serve warm or at room temperature.
